NEW YORK  —  The new Navy assault ship USS New York, built with World Trade Center steel, arrived in its namesake city Monday with a 21-gun salute near the site of the 2001 terrorist attack.

First responders, families of Sept. 11 victims and the public gathered Monday at a waterfront viewing area, where they could see the crew standing at attention along the deck of the battleship gray vessel.

The big ship paused. Then the shots were fired, with a cracking sound, in three bursts.

The bow of the $1 billion ship, built in Louisiana, contains about 7.5 tons of steel from the fallen towers.

"It's a transformation ... from something really twisted and ugly," said Rosaleen Tallon, who lost her firefighter brother, Sean, on 9/11. "I'm proud that our military is using that steel."

Tallon said her brother, who was also was a Marine, also would have been proud.

JoAnn Atlas, of Howells, N.Y., who lost her husband, fire Lt. Gregg Atlas, draped a flag-themed banner along the fence. The names of emergency workers who died were written on the red stripes.

"We have to remember. It's a way to honor them," she said.

Of the 361 sailors serving aboard the ship, around 13 percent are from New York state, which is higher than would normally be the case, Murphy said. There were many requests from Navy personnel to serve on the ship, which will carry some 250 Marines.

After the ground zero stop, the ship — ecorted by about two dozen tugboats and other vessels — headed up the Hudson River toward the George Washington Bridge. After a U-turn there, it was to head south to Pier 88. An official commissioning ceremony is scheduled for Saturday.

The New York will remain in the city through Veteran's Day and then head to Norfolk, Va., for about a year of crew training and exercises, Murphy said.

The ship is 684 feet long and can carry as many as 800 Marines. Its flight deck that can handle helicopters and the MV-22 Osprey tilt-rotor aircraft.

It was scheduled to be built before the terrorist attacks. About a year later, the announcement came that the ship would bear the name New York to honor the city, state, and those who died.

It's the latest in a line of Navy ships to bear that name. The others included a Spanish-American War-era cruiser, a battleship that served in World Wars I and II and a nuclear submarine retired from the fleet in 1997.

The ship is technically known as a San Antonio-class amphibious dock vessel. Four vessels in that class are in service, the USS San Antonio, USS New Orleans, USS Mesa Verde and USS Green Bay. Four others are being built. Of those, two also have been named in connection with the Sept. 11 attacks.

The USS Arlington was named to honor the attack on the Pentagon. The USS Somerset was named after the county in Pennsylvania where United Airlines flight 93 crashed.

What an awesome ship... and an awesome tribute to those who perished in the terrorist attack. That steel will be put to good use fighting terror around the globe!

Ares I Rocket Launch a Soaring Success!

NASA Ares I Launch - 10-28-09

NASA Ares I Launch - 10-28-09

NASA Constellation Program

NASA Ares Concept

CAPE CANAVERAL, Fla. —  At 11:30 a.m. Wednesday morning, the Ares 1-X experimental rocket — the next-generation of America's space flight program — blasted off flawlessly through clear skies at Cape Canaveral.

This launch shows how challenging rocket science really is: Blue skies over the launch pad in Florida hid a variety of challenges, including static-filled clouds and high-altitude winds.

Launching a rocket through these conditions isn't like a plane taking off from a landing strip: It's more like shooting a rubberband through a keyhole from across a parking lot.

At 11:26, NASA resumed the 4-minute launch countdown that had been on pause since 8 a.m Tuesday morning. The ignition system armed, the water and electrical systems activated, and at 11:30 a.m., the Ares 1-X experimental rocket blasted off through clear skies from NASA's launch pad in Florida.

The ship passed Mach 2, achieving speeds of over 1,540 mph. Then, at 22.2 nautical miles up in the air, "burnout" occurred, a stage at which the two segments of the rocket separate and the capsule falls back to Earth.

The test rocket includes a real solid-rocket first stage, with a mock second stage and dummy Orion crew capsule on top to simulate the intended weight and size of Ares I. Ares I-X is the tallest booster in service or about to fly and stands about 327 feet high — 14 stories taller than NASA's space shuttles.

This rocket could eventually take man into space, back to the moon. In an actual moon launch, the second stage of the rocket will contain the liquid propellant that carries the capsule further into space, and ultimately into orbit.

Clouds, snagged tethers and even a misdirected cargo ship within the danger area in the Atlantic Ocean contributed to an eventual postponement in Monday's scheduled launch of the Ares 1-X.

Check out the article at Fox News.

It's nice to see NASA's Constellation Program moving right along ahead of schedule. It would be really nice to see American astronauts avoid having to hitch a ride on Russian rockets!

Crop Circles!

Most Complex Crop Circle Ever Depicts Pi

Astronomical Crop Circle

3D Crop Circle

3D Crop Circle

Jellyfish Crop Circle

Google's homepage is today given over to a "doodle" showing a flying saucer hovering over crop circles. The word "Google" is spelt out in several crop circles, with what appears to be a tractor completing the letter "L".

The internet giant also posted a tweet on its Twitter account with the map reference 51.327629, -0.5616088, which eagle-eyed sci-fi fans have identified as the centre of the small town of Horsell in Surrey. This was the spot where HG Wells set the first UFO landing in his novel The War of the Worlds.

Everyone's trying to read deep significance into this. Is it about abduction? Or aliens? Or Horsell? Or just crop circles? No. It's almost certainly a viral marketing campaign teasing people ahead of some launch in a week or two. One possible explanation is that it's trailing an online "happening" that will coincide with the 143rd anniversary of Wells's birth next week.

Crop circles were once fascinating additions to the English countryside, but now they have become tacky vehicles for corporations to advertise just about anything. A cottage industry has grown up with groups of circle-makers ready - for a price - to reproduce just about anything. The Royal Bank of Scotland, Disney, NBC, UKTV, Red Bull, Greenpeace, Microsoft, Nike, Shredded Wheat, Pepsi, Weetabix, the BBC, The Sun, Mitsubishi, O2, Big Brother, National Geographic, and the Discovery Channel have all paid to emblazon fields with their signatures.

Solar Sunflowers

Fifteen flower-shaped solar panels have been installed in an open space between a highway and a retail lot in Austin, Texas.

They not only provide a green source of energy, but also bring a fresh look to solar panel design.

Designed by Massachusetts art duo Harries/Heder, the SunFlowers are an art exhibit at heart, and stand over 30 feet tall.

They collect power from the sun by day, and use that energy to power their blue LEDs at night.

Up to 15 kilowatts of surplus power is sent back to the grid as payment for any maintenance fees the SunFlowers incur.

Cool idea! I need some of those for my yard... wonder how much they cost!

How Humans Will Get to Mars

Mission to Mars

Mission to Mars

Mission to Mars

Mission to Mars

As the 40th-anniversary celebrations of the moon landing end, a human voyage to Mars remains a holy grail for NASA.

"We're still looking at human exploration of Mars as one of the goals of the future at the top level," said NASA researcher Bret Drake with Lunar and Mars Integration at Johnson Space Center in Houston. "Having a human actually set foot on another planet would be one of the greatest adventures possible, one of the greatest monuments to history."

A crewed mission to the red planet is a daunting challenge that lies at the edge of current technological capabilities and possibly beyond. Still, NASA keeps a strategy to go there and constantly keeps up to date with new ideas.

"Mars is one of those targets of fascination that has been around a long time," Drake said.

How to get there

A voyage to Mars would take a crew about 180 days. So far NASA is exploring two options for propulsion there — a nuclear thermal rocket and a chemical engine.

A nuclear thermal rocket, based off designs from the '60s and '70s, would use a nuclear reactor to super-heat a gas and blast it out the nozzle to generate thrust. "It's a very high-performance vehicle, and we think it's very safe, not radioactive at launch, but it is a nuclear system," Drake said. "The idea for the chemical engine is similar to that used on the space shuttle, liquid oxygen and liquid hydrogen. It's a fairly well-known technology, but it's not as efficient as nuclear thermal."

To reach the Martian surface, NASA envisions an aerodynamic lander that flies down with thrusters to help it descend. The ascent vehicle that takes the crew back into space for the six-month trip home will likely rely on a combination of methane and liquid oxygen. "Oxygen is present in the Martian atmosphere in the carbon dioxide, so you can use resources on Mars to make it," Drake said.

Before the crew even gets to Mars, the plan is to send as much cargo there ahead of time as possible.

"That way we can know it's operating right before we ever commit the crew," Drake said. "A Mars mission is not like a lunar mission where you can come home at any time — once they're committed, a crew is out there for years."

By current NASA estimates, a crewed mission to Mars needs to lift about twice the mass of the International Space Station into space — roughly 1.76 million lbs. (800 metric tons) of technology. To launch the equipment, NASA plans on using the Ares V rocket, designed to be the most powerful rocket ever built and capable of carrying about 414,000 lbs. (188 metric tons) to low Earth orbit at one time.

"We're going to try to minimize the amount of assembly needed," Drake said. "The heavy lift capacity we'll have with the Ares V will allow for simple automatic rendezvous in orbit and docking of components."

The crew would ride up in one of the upcoming Ares I rockets before starting the voyage to Mars.

"Having humans in place could bring a wealth of experience and training and the ability to put into context what they see and to make real-time decisions, all things difficult to do with robots," Drake said.

The very habitat the crew stays at on the Martian surface would be sent ahead of time. "You can also do things like produce and store oxygen from resources at Mars beforehand for the crew and the ascent vehicle. You could generate water as well."

Big crew, long stay

NASA envisions a crew of six astronauts for a Mars mission. "That's about what's required for the skills needed — a commander, scientist, engineer, medical officer, things like that, as well as cross-training," Drake said. "They'll need expertise in a wide range of disciplines."

Currently NASA envisions a long stay for a crew at Mars, about 500 days.

"Crew autonomy is vital, because there's an up to 40 minute time delay in communication between Earth and the crew because of the distance," Drake said. "And the crew doesn't have a capability for re-supply — they'll just have what they send ahead or what they bring with them — so when things fail, they'll have to be able to repair them. They must be self-sufficient."

To survive the voyage, air and water need to be completely recycled regularly.

"We're learning a lot on the International Space Station right now on air revitalization and water recovery," Drake said. "What's nice about Mars is that there's carbon dioxide in the atmosphere, so that can help get us oxygen and water for the crew. In terms of food, we're looking at smaller systems, 'salad machines,' to grow food for the crew. Fresh food is not only good for nutrition, but good for the mind as well. A fresh tomato can really boost psychology."

Mental and physical challenges

The long hardship of roughly two-and-a-half years in space with only a few people in a potentially lethal environment will undoubtedly challenge the psyches of Mars explorers.

"The Russians are conducting a test right now that hopefully will shed light on the behavioral sciences aspect of a Mars mission," Drake said. "Looking at other remote exploration endeavors is helpful as well — Antarctica, or submarines — all that feeds into the human behavioral aspects of crew selection."

A key concern for astronauts as well as during the stay on Mars is dangerous radiation in the form of storms of high-energy particles from the sun as well as cosmic rays from deep space. "The best radiation protection material is hydrogen, or water, which is rich in hydrogen," Drake said.

On the surface of Mars, NASA envisions that cargo deployed ahead of time can produce water before the crew arrives to use as a shield during the crew's stay there. On the way to and from Mars, the ship could be configured so that water and food surround areas where crew spend most of their time, but "a 'storm shelter' aboard the ship will be an integral part for short events of radiation that can be lethal," Drake said.

No firm date has been set for any potential Mars mission, but it remains of keen interest not just to NASA, but also others, such as China.

"It's humanity's next step to understanding and expanding our presence outward," Drake said. "We view human exploration of Mars as being an international endeavor, most likely not limited to just one country, but probably of global scale.

Check out the article at Fox News.

If human exploration and colonization of Mars is a subject that interests you, I highly recommend Kim Stanley Robinson's Mars Trilogy - consisting of Red Mars, Green Mars, and Blue Mars. In this awesome work of science fiction, Robinson delves into the technological, social and political aspects in a realistic future of Martian colonization and terraforming. You'll find no light-sabres or warp drives in these books... just down-to-earth, well-written sci-fi!!!

CAPE CANAVERAL, Fla. - Neil Armstrong moved slowly down the ladder. Getting to the moon had been a long time coming. He was an Ohio pilot who came from the same soil as Orville and Wilbur, who ejected from a crippled jet fighter over Korea just after turning 21, who flew seven test flights in the X-15 rocket, who saved himself and a crewmate in Gemini 8, who ejected from a lunar landing trainer a split second before it crashed.

In the 1950s and '60s, he flew about every propeller, jet, rocket and helicopter built by his country. To say that this Midwestern farmboy was the best test pilot in an emergency ever was an easy argument. That’s why chief astronaut Deke Slayton chose Neil Armstrong to take the first step on a small world that had never been touched by life. A landscape where no leaf had ever drifted, no insect had ever scurried, where no blade of green ever waved, where in the silence of vacuum even the fury of a thermonuclear blast would sound no louder than a falling snowflake.

More than 200,000 miles away, billions of eyes stared at the black-and-white TV picture. They watched Neil’s ghostly figure move like a spacesuited phantom, closer and closer, planting his boots in moondust at 10:56 p.m. ET, July 20, 1969.

All motion stopped. "That's one small step for a man," Neil said slowly, "one giant leap for mankind."

Neil gathered several ounces of rock and soil from the lunar surface and stuffed the invaluable material in a suit pocket. The plan was, after Buzz Aldrin joined him, they would remain outside for two hours, planting experiments and collecting primarily rocks, but if something should go wrong, at least they would have a tiny bit of the moon.

With the contingency sample safely tucked away, he took the time to look around. “The moon has a very stark beauty all its own,” he said, almost whispering. “It’s like much of the high desert areas of the United States. It’s different, but it’s pretty out here.”

What we on Earth did not know at the time was exactly why history’s first moonwalk began when it did. NASA had scheduled a four-hour sleep and rest period for Armstrong and Aldrin in the lunar module, or LM, and we were told to wait.

It turned out that we were hoodwinked.

The truth came out last November. NBC News President Steve Capus was giving me a dinner to celebrate my 50 years at the network. Former astronauts Neil Armstrong, John Glenn and Edgar Mitchell flew in, along with other survivors of the old days. Following dinner and a short ride to one of our favorite watering holes, Neil spilled the beans.

“Of course we wanted to get outside as soon as possible, before an emergency. But we thought we would need several hours to get the LM’s fluids and systems settled,” he explained.

"For several hours you reporters would have been speculating, guessing about possible problems, and we didn’t want one of you inventing stories,” Neil grinned. “That’s why we put in a four-hour sleep and rest period we hoped we would never use.”

We laughed, and Neil laughed, and he added, “Everything went much faster than we expected.”

Most of us were having dinner when the call came that the moonwalk would begin early. We rushed back to our microphones and reported the history-making event of our lives.

Buzz takes his turn

While Neil took his one small step, Buzz Aldrin stayed aboard the lunar module, which they named Eagle, to monitor its systems. That was his duty as lunar module pilot, and that was one reason why he was the second man to walk on the moon. When he and Mission Control were convinced that the Eagle was safe and purring, he joined Neil on the surface.

“Beautiful, beautiful! Magnificent desolation,” Buzz said as he stared at a sky that was the darkest of blacks above a landscape that was many shades of gray, a touch of brown, and utter black where the rocks cast their shadows. No real color, not even the places lit by the unfiltered sun.

Then there was the weak gravity. They weighed only one-sixth of their Earth poundage, and Neil reported, “The surface is fine and powdery. It adheres in fine layers, like powdered charcoal, to the soles and sides of my boots. I only go in a fraction of an inch, maybe an eighth of an inch, but I can see the footprints of my boots and the treads in the fine, sandy particles.”

Was the moonwalk faked? No!

It would be these highly defined footprints that would set some armchair physicists crying the moonwalk was a fake. In the years to come there would be those who would claim Apollo astronauts never went to the moon. They said all of it was done on a movie set in an Arizona.

It occurred to me that if NASA had been so deviously smart to persuade 400,000 Apollo workers to lie, to persuade the Russians to lie, to persuade the people tracking the lunar flights with giant radio antennas around the world to lie ... well, if NASA got away with it once, would the agency be so stupid as to try to get away with this world-class hoax nine times?

The claim is too dumb not to be laughable. It is sad. We as a people would rather think the worst of ourselves than the best.

Nevertheless, scientific investigators investigated.

Myth-believers claimed that Neil and Buzz could have only left such firm, defined bootprints in soil with moisture — and everyone knows there is no water on the moon, right?

Wrong. There’s now evidence there could be water ice at the poles, but that hasn’t a thing to do with the first footprints on the moon.

Close examination of the lunar soil back on earth showed it to be virgin. The grains still had their sharp edges. They had not been rounded off by wind and erosion in an atmosphere. In their vacuum the sharp edges of lunar soil cling together, leaving a smooth surface much as moist sand does on a beach.

"Where were the stars," the myth-believers ask. "Where’s the crater carved out by Eagle's descent rockets during landing?"

The cameras that NASA sent to the moon had to use short-exposure times to take pictures of the bright lunar surface and the moonwalkers' white spacesuits. Stars’ images were too faint and underexposed to be seen, as they are in photographs taken from Earth orbit. And why didn’t the descent rockets carve out a crater? Their thrust was simply too weak to make a huge dent in the lunar surface.

So much to see, so little time

For Neil and Buzz there was so much to see and do and so little time. They moved their television camera 60 feet from Eagle. This would help Earth’s viewers see some of the things they were seeing and let them watch them going about the business of setting up Apollo 11’s experiments.

The two had problems jamming the pole that held the American flag into the lunar surface. Though a metal rod held the flag extended, the subsurface soil was so hard that they had to bang and push on the pole to get it to barely remain erect. Their forcible actions left the flag’s staff rocking back and forth for an unusual length of time.

Ah, said the myth-believers. That’s wind blowing the flag, and everyone knows there’s no wind on the moon. Right?

Right, there’s no wind on the moon. No atmosphere, just vacuum. And everyone knows an object that is forced into repeating motions in vacuum repeats many more times than it does in atmosphere. Atmospheric drag dampens movement. Vacuum is nothing. No resistance.

The flag’s motion was later duplicated in a vacuum chamber at the Marshall Space Flight Center in Huntsville, Alabama.

No fraud, no conspiracy.

With Old Glory standing, Neil moved off to take more pictures while Buzz set up a seismometer to gather information on quakes and meteorites hitting the moon. An instrument to measure the flow of radiation particles inside the solar wind and a multi-mirror target for returning laser beams fired from Earth were deployed — laser reflectors that have been used by American universities and Russian institutes and other global investigators to determine the distance between Earth and the moon to the inch.

Those laser reflectors could not have been used if Neil and Buzz had not put them there.

Just days ago, NASA's Lunar Reconnaissance Orbiter, launched last month from Cape Canaveral, returned its first images of the Apollo moon landing sites. The pictures show five of the six Apollo descent stages, including Apollo 11's, resting on the moon's surface. The Apollo 14 landing area shows a faint trail of Alan Shepard and Edgar Mitchell's two-mile round-trip march to Cone Crater with their "rickshaw."

Guess we really did go to the moon, huh? So much for the myth-believers and the conspiracy theorists.

In the lunar dust, the two Americans placed mementos for the five astronauts and cosmonauts who had lost their lives, and Neil read the words on a plaque mounted on Eagle's descent stage: “Here men from the planet Earth first set foot upon the moon, July 1969, A.D. We came in peace for all mankind.”

Neil and Buzz gathered about 46 pounds of lunar materials, and once everything was loaded for flight back to Earth, they shut down the first moonwalk.

Was Buzz Aldrin a publicity hog? No!

Because of the primitive state of television at the time, most of us couldn’t wait for Apollo 11 to get back with all the great pictures the crew had shot. That in itself was the beginning of yet another controversy.

When all the film had been developed, there was only one image out of the 121 Hasselblad still-camera photographs that showed Neil on the moon, plus the film from a 16mm movie camera that was set up to peer out one of Eagle's windows. Neil had taken great shots of Buzz moving about, Aldrin took only one rear shot of Neil stowing samples for return to Earth.

Why?

Was Buzz angry?

No.

“I was the one with the camera,” Neil told me. “His job was to set up the experiments. He had much to do. Nothing more than that.”

Two months ago I had the same conversation with Buzz, and got a similar response. “NASA should have trained us in public relations,” he said with passion. “We were just doing our job.”

Simply put, MIT-educated Buzz Aldrin was one of the smartest guys in the astronaut corps.

During Project Gemini, spacewalker after spacewalker had failed. They tired quickly, and Buzz studied their problems. By the time he stepped into space, he had invented the tools and methods needed to walk in a vacuum. For example, he fashioned a pair of golden slippers that could be placed where needed to hold his booted feet. A spacewalker needs that — something to hold his or her feet in place — to keep stable attachment with the spaceship. Otherwise you will thrash about wildly. During Gemini 12, Buzz Aldrin whistled and sang through his spacewalk assignments.

And when he returned from the moon, when one of those moon-conspiracy theorists shoved a Bible in Aldrin’s face and ordered him to swear on it that he walked on the moon, Buzz decked him. Fellow astronaut Wally Schirra, one of the original Mercury 7, renamed him Rocky. That’s my kind of man.

After 51 years on the job, after covering every spaceflight flown by Americans, I can report that Neil Armstrong and Buzz Aldrin — and Michael Collins, who kept stoking the home fires on board the Apollo 11’s command ship Columbia — were the best Earth had to offer.

History, this time we got it right.

Happy 25th Birthday Tetris!

Happy 25th Birthday Tetris!

Happy 25th Birthday Tetris!

Happy 25th Birthday Tetris!

NEW YORK — With its scratches and sticky brown beer stains, the "Tetris" arcade machine near the back of a Brooklyn bar called Barcade has seen better days. Which makes sense, given that the machine was made in the 1980s.

Even today, though, it's not hard to find 20- and 30-somethings plucking away at its ancient controls, flipping shapes made up of four connected squares and fitting them into orderly patterns as they descend, faster and faster as the game goes on.

"You could just play infinitely," said Michael Pierce, 28, who was playing against Dan Rothfarb, also 28. Both have been fans since they — and the game — were young. "Tetris" has its 25th birthday this week.

Completed by a Soviet programmer in 1984, "Tetris" has come a long way from its square roots. It's played by millions, not just on computers and gaming consoles but now on Facebook and the iPhone as well.

"Tetris" stands out as one of the rare cultural products to come West from the Soviet Union during the Cold War. And the addictive rhythm of its task-by-task race against time was an early sign of our inbox-clearing, Twitter-updating, BlackBerry-thumbing world to come.

In her book "Hamlet on the Holodeck," Georgia Tech professor Janet Murray called "Tetris" the "perfect enactment of the overtasked lives of Americans."

The game, she wrote, shows the "constant bombardment of tasks that demand our attention and that we must somehow fit into our overcrowded schedules and clear off our desks in order to make room for the next onslaught."

Many people who grew up with "Tetris" haven't stopped playing.

"Tetris" is easy to pick up. Rotate the falling shapes so that you form full lines at the bottom of the screen. Fit the shapes so there are as few open spaces left as possible. Aim for a Tetris: four lines completed in one swoop. Repeat. Watch your score zoom.

But Tetris is hard to master. Because the shapes — technically known as tetrominoes — come in a random order, it is hard to predict the best way to organize them so that they can form neat rows.

In fact, in 2002, Massachusetts Institute of Technology researchers determined that the potential combinations are so numerous that it would be impossible even for a computer to calculate the best place to put each falling shape.

Erik Demaine, an associate professor of computer science, praised the game's "mathematical elegance," which perhaps stems from the background of its developer.

Alexey Pajitnov was 29 and working for the Moscow Academy of Sciences when he completed "Tetris" on June 6, 1984, for a Soviet computer system called the Elektronika.

A computer programmer by day who researched artificial intelligence and automatic speech recognition, Pajitnov worked on the game in his spare time.

"All my life I liked puzzles, mathematical riddles and diversion," Pajitnov said in a recent interview from Moscow. "Tetris," he said, was just one of the games he made back then. The others are mostly long forgotten.

Pajitnov's creation spread in Moscow through the small community of people who had access to computers. Word filtered through computer circles to the West, where the game drew the interest of entrepreneurs.

A company called Spectrum HoloByte managed to obtain PC rights, but another, Mirrorsoft, also released a version.

Years of legal wrangling followed, with several companies claiming pieces of the "Tetris" pie — for handheld systems, computers and arcades.

Complicating matters, the Soviet Union did not allow privately held businesses. The Soviet state held the "Tetris" licensing rights and Pajitnov had no claim to the profits. He didn't fight it.

"Basically, at the moment I realized I wanted this game to be published, I understood that Soviet power will either help me or never let it happen," he said.

It wasn't until 1996 that Pajitnov got licensing rights. Asked whether he made enough money off the game to live comfortably, he says yes, but offers no more details.

Today, he is part owner of Tetris Co., which manages the game's licenses worldwide.

Nintendo Co. was an early and big beneficiary of the game, which stood out from its mid-'80s peers because it had no characters and no shooting.

When Nintendo was preparing to release its Game Boy device in 1989, the company planned to include with it one of the games that are also classics today: "Super Mario," "Donkey Kong" and "Zelda."

But Nintendo wanted something everyone would play — a "perfect killer game" that would sell the Game Boy, said Minoru Arakawa, the president of Nintendo of America from 1980 to 2002.

The solution was "Tetris" — though Nintendo needed help from Henk Rogers, a U.S. entrepreneur.

Rogers had spotted "Tetris" at the International Consumer Electronics Show in Las Vegas and bought the rights to a PC version of the game in Japan from Spectrum HoloByte.

In February 1989, he went to Moscow on a tourist visa to try to get the rights for Nintendo. He spent his first day in a taxi with a driver who didn't speak English, communicating by gestures and trying in vain to find the ministry of software and hardware export.

The next morning, he hired an interpreter and things went more smoothly, and "Tetris" got bundled into the first Game Boy.

Since then, "Tetris" has expanded to all kinds of devices and inspired a generation of knockoffs. Tetris Co. says 125 million copies have been sold in various incarnations.

Pajitnov says "Tetris" could stick around another quarter-century.

"I hope so, why not?" he said. "Technology changes a lot, but I can't say people change a lot."

Check out article at Fox News.

From playing against my brother via wire on long car trips... to hooking up my grandpa's Super-Gameboy on his TV so he could play Tetris without having to squint at the little screen... to competing against many family members for bragging rights on highest score... to downloading Tetris Party for the Wii and introducing it to my kids... I have many fond memories of this classic game! Congrats on 25 great years!!!

Happy Birthday Samuel Morse!

Samuel Morse Statue

Morse Telegraph

International Morse Code

Morse code is a type of character encoding that transmits telegraphic information using rhythm. Morse code uses a standardized sequence of short and long elements to represent the letters, numerals, punctuation and special characters of a given message. The short and long elements can be formed by sounds, marks, or pulses, in on off keying and are commonly known as "dots" and "dashes" or "dits" and "dahs". The speed of Morse code is measured in words per minute (WPM) or characters per minute, while fixed-length data forms of telecommunication transmission are usually measured in baud or bps.

Originally created for Samuel F. B. Morse's electric telegraph in the early 1840s, Morse code was also extensively used for early radio communication beginning in the 1890s. For the first half of the twentieth century, the majority of high-speed international communication was conducted in Morse code, using telegraph lines, undersea cables, and radio circuits. However, the variable length of the Morse characters made it hard to adapt to automated circuits, so for most electronic communication it has been replaced by machine readable formats, such as Baudot code and ASCII.

The most popular current use of Morse code is by amateur radio operators, although it is no longer a requirement for amateur licensing in many countries. In the professional field, pilots and air traffic controllers are usually familiar with Morse code and require a basic understanding. Navigational aids in the field of aviation, such as VORs and NDBs, constantly transmit their identity in Morse code. Morse code is designed to be read by humans without a decoding device, making it useful for sending automated digital data in voice channels. For emergency signaling, Morse code can be sent by way of improvised sources that can be easily "keyed" on and off, making Morse code one of the most versatile methods of telecommunication in existence.

Check out article at Wikipedia.

I checked out the Development and History section of the Morse Code article and I must say that I learned something new! Having not known much about the history of Morse Code, I had always assumed that it was originally invented for the same reasons that it has been used for the last 150+ years. Surprisingly enough, the technology evolved through some interesting methods... history never ceases to amaze!

On another note, if the world and all of it's technology were to be turned upside down one day, one could depend on basic technologies such as Morse Code for communication. Those possessing this knowledge would be indispensable! Unfortunately, like many old-school technologies and skills, they are falling by the wayside as digital technologies take over. But one day, it will all blink off and we'll need to know how to do things old-school again... one can only hope the library has some good info in print. But, I digress...

Scientists Race to Prevent 'Catastrophic Disaster' in Space!

Space Debris in Low Earth Orbit

In 1970, Marshall Kaplan, then an aerospace engineering professor at Penn State, had a peculiar dream — he wanted to retrieve Sputnik, the world's first orbiting satellite, from space.

Sputnik had been launched by the Russians in 1957, and by 1970 it was no longer operational. Kaplan wanted to go get it.

NASA had never considered space retrieval before, but it thought it was a good idea. Kaplan got the job, but it didn't work out — because the time frame was too short. Sputnik, nearing the end of its life cycle, was already about to deorbit — the technical term for what happens when an object circling the Earth gets close enough to be caught in gravity and burned to cinders in the atmosphere.

But that didn't mean Kaplan needed a new line of work. In fact, his work was just beginning.

For the next 40 years, Kaplan, now a senior researcher in the space department at the Johns Hopkins University Applied Physics Laboratory in Laurel, Md., has been figuring out how to bring down objects from space.

That makes him one of a few dozen scientists feverishly trying to prevent what he calls a "coming catastrophic disaster" — a collision between a manned spacecraft and orbital debris, or space junk, thousands of pieces of which are zooming at thousands of miles per hour 300 to 800 miles above the Earth, ready to take out anything in their paths.

Space junk is anything that's lost or discarded in orbit — everything from the spare glove astronaut Ed White lost on the first American spacewalk in 1965, to the garbage bags jettisoned by cosmonauts stationed on the Mir space station in the '80s and '90s, to the dangerous remnants of a old weather satellite blasted into smithereens by a Chinese missile in 2007.

The probability of a disastrous orbital collision has been on front pages lately. On Feb. 12, a Russian-made satellite smashed into a commercial U.S. telecommunications satellite, creating the second worst mess (after the deliberate Chinese incident) ever in space.

Fortunately, the telecom satellite was quickly replaced, and the Russian "bird" had long been out of commission.

But a month later, on March 13, the two astronauts and one cosmonaut aboard the International Space Station had to scramble into an escape capsule after they got less than 20 minutes' warning that a piece of speeding junk was heading straight for them.

There wasn't time to reposition the ISS, which could have suffered a fatal loss of pressure had the five-inch piece of an old rocket punctured the walls of a living area. Fortunately, the debris missed.

"This is just a taste of what's to come. Experts are saying we could expect a crash every couple of years, but this is an educated guess," says Michael Krepon, co-founder of The Henry L. Stimson Center, a Washington-based think tank that focuses on security concerns.

"We really don't know the scale of the problem — we just know that we've already done serious damage to a zone of space that's essential to our security."

Our fast-paced, hyperlinked world could not exist without orbital relays; everything from phone calls to GPS devices to banking transfers needs satellites to work.

Even more damaging to satellites, and the enormous potential of the commercial development of space overall, could be a ground-based threat — crippling lawsuits over orbital-debris collisions.

"Liability claims killed the private aviation industry," says Peter Diamandis, founder and chairman of the X Prize Foundation, which sponsors contests and awards for private space ventures and innovation. "In space, we're going to be dealing with 'Your satellite killed my satellite' claims. It's going to be a mess."

No ... it's a mess already.

"We're currently tracking 18,000 objects floating through space," says Kaplan. "But that's only objects larger than 4 inches. At 10,000 mph, even a nut or a bolt could do serious damage."

In the microscopic range, there are literally billions of micro-particles around — too small to puncture a spacecraft's exterior, but enough to have already pitted windows on a space shuttle and destroyed a lens on an orbiting telescope.

It's Kaplan's job to figure out how to get all of this down, and it's a big job.

"This clean-up will cost tens of billions of dollars," he says. "It's going to require a whole new space program to pull off. But we don't have a choice. This is just a cost-benefit analysis. If we don't clean this mess up in the next 20 years, we're going to lose our access to space."

Nations are beginning to act. On Feb. 13, the United Nations endorsed seven "Space Debris Guidelines to Curtail Space Debris in the Future."

The guidelines include adding more shielding to spacecraft and giving satellites extra fuel so they can either deorbit themselves quickly (it normally takes decades) or put themselves into higher, less crowded orbits at the ends of their life cycles.

The Colorado-based Secure World Foundation, a space think tank, is calling for a Civil Space Situational Awareness System — essentially a global air-traffic controller that would track everything in orbit so collisions could be avoided.

That sounds like a no-brainer, but it's something of a problem for the Air Force, to use only one example of a governmental authority that naturally has serious concerns about telling anyone where its surveillance satellites are at any given time.

A Stanford study released in late March suggests that future space junk can be minimized by simply forcing nations to "take out their own garbage" by deorbiting anything after it's done its job.

Most experts feel the U.N. recommendations will be ratified by international treaty, or a similar mechanism for good-conduct rules will be enacted soon.

But while all of these ideas are good planning, they don't get rid of the junk that's already up there.

That's what Kaplan spends most of his time working on.

Recently, he conducted a global survey of orbital waste-management ideas. He got over 100 — some pipe dreams, some crack-pipe dreams, but 30 or 40 of them with merit.

One concept that's gotten attention is the "space broom," a ground-based laser that will use quick pulses to singe orbital debris, changing each piece's trajectory so that it deorbits faster. The idea has considerable merit, and considerable problems — how to hit each piece, for one.

"We don't really know where this junk is with any real sense of accuracy," says Kaplan. "We can get within a few meters, perhaps, but that's not enough for a laser."

You could get a lot closer by putting the lasers on a spacescraft, but that would be a space-based weapon, and those are banned by several international treaties.

"Collection by collision" is another possibility Kaplan is earnestly examining.

The idea is simple — coat a spaceship in something sticky and put it into orbit. Think of it as a giant lint roller — debris will naturally collide with the craft, but instead of bouncing off or tearing through it, the junk will simply adhere. The added mass will lower the ship until it deorbits on its own.

And then there are a bevy of independent thinkers eager to jump into the mix.

Retired aerospace engineer Jim Hollopeter was profiled in a recent Wall Street Journal article, which reported that he wants to load aging rockets with water and bring down debris with what would essentially be the world's largest fire hose.

Meanwhile, the folks at Tether Unlimited, a Washington-based aerospace company funded by the Air Force, have created the "terminator tape," basically a pizza-sized box that can be clamped on to to a defunct satellite.

Once attached, the box opens, several hundred meters of electro-dynamic wire unspool and atmospheric drag does the rest to bring the bird down.

There are also nets, and magnets, and a science-fiction treasure trove of tantalization. The bad news is that none of them, even something as low-tech as the terminator tether, comes cheap.

The good news is that many could be "bootstrap"-financing technologies. There's a fortune to be made in space-mining operations, for example in harvesting nickel from the moon.

Diamandis himself believes this future industry will produce the world's first trillionaire, and if the fortunes of the 19th-century "robber barons" are anything to go by, he may not be wrong.

The point is that cleaning debris out of space means learning how to tow objects around space — a fundamental component of any mining operation.

"You don't even have to go that far out," says Diamandis. "Whatever 'waste management' organization gets the contract for space is looking at heaps of valuable material already floating around above us. You have to remember — one man's waste is another's treasure."

It seems that wherever we go, humans somehow manage to pollute and litter the environment. When will we ever learn... LEAVE NO TRACE!!!

The Science of the Spring Equinox

Spring Equinox 2009

Spring Equinox 2009

Spring Equinox 2009

The first day of spring is no guarantee of spring-like weather, but officially the season's start comes around at the same time each year nonetheless.

Well, sort of.

The first day of spring arrives on varying dates (from March 19-21) in different years for two reasons: Our year is not exactly an even number of days; and Earth's slightly noncircular orbit, plus the gravitational tug of the other planets, constantly changes our planet's orientation to the sun from year to year.

And weather-wise, Earth's seasons have shifted in the past 150 years or so, according to a study that came out last month.

The hottest and coldest days of the years now are occurring almost two days earlier.

This year, spring starts Friday, March 20, because that is when the so-called vernal equinox occurs. Equinoxes (which mark the onset of spring and autumn) and solstices (which mark when summer and winter begin) are points in time and space that mark a transition in our planet's annual trip around the sun.

At each equinox, the sun crosses the Earth's equator, making night and day of approximately equal length on most of the planet. At the equator, the sun is directly overhead at noon on either equinox.

How it works

Earth's multiple motions — spinning on its axis and orbiting the sun — are behind everything from day and night to the changing seasons.

The sun comes up each day because Earth rotates once on its axis every 24 hours or so. Seasons are a result of Earth being tilted 23.5 degrees on its spin axis coupled with the planet's 365-day orbit around the sun.

(At the North Pole, the sun rises only once a year — at the start of spring. It gets higher in the sky each day until the summer solstice, then sinks but does not truly set until late September, at the autumn equinox.)

Imagine Earth as an apple sitting on one side of a table, with the stem being the North Pole. Tilt the apple 23.5 degrees so the stem points toward a candle (the sun) at the center of the table. That's summer for the top half of the apple.

Keep the stem pointing in the same direction but move the apple to the other side of the table: Now the stem points away from the candle, and it's winter on the top half of the fruit.

The very top of the apple, representing the north polar region, is in total darkness 24 hours a day, during that season.

At winter solstice, the sun arcs low across the Northern Hemisphere sky for those of us below the Arctic Circle, and the stretch of daylight is at its shortest. By the time of the spring equinox, days have grown noticeably longer.

At the summer solstice, the sun gets as high in our sky as it can go, yielding the longest day of the year in the Northern Hemisphere.

As long ago as the fourth century B.C., ancient peoples in the Americas understood enough of this that they could create giant calendars to interact with the cycle of sunlight. They built observatories of stone to mark the solstices and other times important for planting or harvesting crops. Shrines and even tombs were also designed with the sun in mind.

More seasonal facts

As we orbit the sun, the part of the night sky that's in our view changes. A given star sets about 4 minutes earlier each night. Over a month, this amounts to two hours.

In winter, this means that we're looking at stars that during the summer were in our daytime sky, overwhelmed of course by the glare of the sun. Since we complete a circle around the sun every year, the stars of summer, such as those in the Big Dipper, are always the stars of summer.

During summer on the top half of Earth, our planet is actually farther from the sun than during winter, a fact owing to our non-circular orbit around the sun. The difference is about 3 million miles (5 million kilometers), and it makes a difference in radiant heat received by the entire Earth of nearly 7 percent.

But the difference is more than made up for by the longer days in the Northern Hemisphere summer with the sun higher in the sky.

Which brings up a common question: If the summer solstice is the longest day of the year, why are the dog days of August typically hotter?

Because it takes a while for the oceans to warm up, and a lot of weather on land is driven by the heat of the oceans.

Engineering Breakthrough = Space Elevator Tech?

Space Elevator Station

Space Elevator

Space Elevator Diagram

Ever since it was first popularized by Arthur C. Clarke, the idea of a "space elevator" has languished in the realms of science fiction. But now a team of British scientists has taken the first step on what could be a high-tech stairway to heaven.

Spurred on by a $4 million research prize from NASA, a team at Cambridge University has created the world's strongest ribbon: a cylindrical strand of carbon that combines lightweight flexibility with incredible strength and has the potential to stretch vast distances.

The development has been seized upon by the space scientists, who believe the technology could allow astronauts to travel into space via a cable thousands of miles long — a space elevator.

They predict the breakthrough will revolutionize space travel. Such an elevator could potentially offer limitless and cheap space travel.

At a stroke, it would make everything from tourism to more ambitious expeditions to Mars commercially viable. The idea couldn't come too soon for NASA, which spends an estimated $500 million every time the shuttle blasts off, not to mention burning about 900 tons of polluting rocket fuel.

Check out the article at Fox News.

Can you imagine the view from up there? Whenever they build it, I'm taking a ride up to the space elevator resort! =)

USS George H. W. Bush

Nimitz Class Aircraft Carrier

Commissioning of Aircraft Carrier USS George H. W. Bush

NORFOLK, Va. — It's the perfect gift for an old Navy flier: 1,092 feet of flattop.

"What do you give a guy who has been blessed and has just about everything he has ever needed?" asked President George W. Bush from aboard the Navy's newest ship. "Well, an aircraft carrier."

The USS George H.W. Bush, a steel-gray vessel longer than three football fields and built at a cost of $6.2 billion, was commissioned Saturday with its namesake, the 41st president, and other members of the Bush family on hand for the ceremonies at Naval Station Norfolk.

Adorned for the day with red, white and blue bunting, the USS George H.W. Bush is one of the Nimitz class of nuclear-powered aircraft carriers, the largest warships in the world.

"The ship that bears our dad's name is more than 95,000 tons of aluminum and steel," Bush said from a podium tucked under the flight deck. "She will carry nearly 6,000 of the finest sailors and Marines in the world. She represents the craftsmanship of many skilled builders, and thousands of hours of preparation."

Bush, who took his last scheduled flight aboard Air Force One to get to Norfolk, added: "Laura and I are thrilled to be here to help commission an awesome ship and to honor an awesome man."

It was the ultimate honor for former President George H.W. Bush, a decorated World War II pilot.

The former president recalled the day 65 years ago in Philadelphia when he attended the commissioning of the USS San Jacinto, a light carrier on which he served during the war. It was during that trip, he said, that he gave his fiancee, Barbara, an engagement ring.

"I thought that the San Jac was by far the biggest ship, or anything else, I'd ever seen," said the elder Bush, comparing it to the massive aircraft carrier, spit and polished for its unveiling. He marveled at its 4.5-acre landing field, a tower that reaches 20 stories above the waterline and its 1,400 telephones.

Speaking to the sailors preparing to serve on the new ship, his voice quavering at times with emotion, the former president said: "I wish I was sitting right out there with you, ready to start the adventures of my naval aviation career all over."

Bush, 84, joined the Navy on June 12, 1942, his 18th birthday and six months after the Japanese attack on Pearl Harbor. During the war he flew torpedo bombers off the USS San Jacinto. He was awarded the Distinguished Flying Cross and three Air Medals for his service.

On a mission over the Pacific in September 1944, Bush's plane crashed into the ocean after being hit by Japanese anti-aircraft fire. The future president parachuted into the sea and was rescued by a Navy submarine. He returned to combat and served until the end of the war.

The Nimitz class of nuclear-powered aircraft carrier was first launched in 1972. The USS George H.W. Bush is the 10th and final vessel of its type.

A bronze statue on its hangar bay deck depicts the former president as a youthful, smiling pilot in his flight suit. On an upper deck, a "tribute room" presents Bush's life from his days in the Navy to his four years in the White House.

No other former president has visited a carrier named after him. Ronald Reagan was the first living ex-president to have a carrier named in his honor, but he was unable to visit the vessel before he died.

Doro Bush Koch, the president's sister and ship's sponsor, had the honor of bringing the carrier to service, calling out: "Man our ship. Bring her to life." With that, hundreds of sailors charged up gangplanks as a band played "Anchors Aweigh," the song of the Navy.

Four F-18s flew overhead, followed by a solo World War II torpedo bomber similar to the one the elder Bush flew during the war.

The president's daughters, Jenna Hager and Barbara Bush, and Vice President Dick Cheney and his wife, Lynne, were among the throng of attendees. Also on hand were Secretary of State Condoleezza Rice, Defense Secretary Robert Gates, Adm. Michael Mullen, chairman of the Joint Chiefs of Staff, and Virginia Gov. Tim Kaine.

Check out article at Fox News.

You have to admit... the Nimitz Class Nuclear-Powered Aircraft Carrier is one awesome and intimidating piece of naval technology. We can be thankful that no other nation in the world can match the power that one of these holds... not to mention all ten of ours!

Congratulations to President H W Bush on this honor!

Each year, millions of eyes from all over the world are focused on the sparkling Waterford Crystal Times Square New Year's Eve Ball. At 11:59 p.m., the Ball begins its descent as millions of voices unite to count down the final seconds of the year, and celebrate the beginning of a new year full of hopes, challenges, changes and dreams.

On November 11th, 2008, The co-organizers of New Year’s Eve in Times Square (Times Square Alliance, Countdown Entertainment) unveiled a new Times Square New Year’s Eve Ball at a press conference at Hudson Scenic Studio in Yonkers, New York.

The new Times Square New Year’s Eve Ball is a 12 foot geodesic sphere, double the size of previous Balls, and weighs 11,875 pounds. Covered in 2,668 Waterford Crystals and powered by 32,256 Philips Luxeon Rebel LEDS, the new Ball is capable of creating a palette of more than 16 million vibrant colors and billions of patterns producing a spectacular kaleidoscope effect atop One Times Square.

The organizers also announced that the new Ball will become a year-round attraction above Times Square in full public view January through December.

“For one hundred years, the Times Square New Year’s Eve Ball has attracted millions of revelers to Times Square on December 31st to celebrate the beginning of the New Year” said Jeff Straus, president of Countdown Entertainment and co-organizer of Times Square New Year’s Eve. “The new Times Square New Year’s Eve Ball will be a bright sparkling jewel atop One Times Square entertaining New Yorkers and tourists from around the world not only on December 31, but throughout the year.”

“The New Year’s Eve ball is bigger, better and brighter than ever, just like Times Square itself,” said Times Square Alliance President Tim Tompkins. “And like Times Square, it’s not afraid to show off. That’s why we’re proudly putting it on display year-round so visitors to the neighborhood can enjoy a true Crossroads of the World icon.”

Just a second, 2009 - the Earth needs to catch up!

Greenwich Meridian Line at the Royal Observatory in Greenwich, London

Greenwich Meridian Line at the Royal Observatory in Greenwich, London

AT THE GREENWICH PRIME MERIDIAN, England (AP) -- Just a second, 2009. It's going to take a little longer to say goodbye to the worst economic year since the Great Depression, but all for good cause. The custodians of time will ring in the New Year by tacking a "leap second" onto the clock Wednesday to account for the minute slowing of the Earth's rotation. The leap second has been used sporadically at the Royal Observatory at Greenwich since 1972, an adjustment that has kept Greenwich Mean Time the internationally agreed time standard.

Some scientists now say GMT should be replaced by International Atomic Time - computed outside Paris - because new technologies have allowed atomic time to tick away with down-to-the-nanosecond accuracy.

But opponents say atomic time's very precision poses a problem.

A strict measurement, they say, would change our very notion of time forever, as atomic clocks would one day outpace the familiar cycle of sunrise and sunset.

The time warp wouldn't be noticeable for generations, but within a millennium, noon - the hour associated with the sun's highest point in the sky - would occur around 1 o'clock. In tens of thousands of years, the sun would be days behind the human calendar.

That bothers people like Steve Allen, an analyst at the University of California at Santa Cruz's Lick Observatory.

"I think (our descendants) will curse us less if we choose to keep the clock reading near 12:00 when the sun is highest in the sky," Allen said.

Atomic time advocates argue that leap seconds are onerous because they're unpredictable.

Since the exact speed of the Earth's rotation can't be plotted out in advance, they're added as needed. Sometimes, like this year, they're added on Dec. 31, sometimes they're inserted at the end of June 30.

Those willy-nilly fixes can trip up time-sensitive software, particularly in Asia, where the extra second is added in the middle of the day.

Critics say everything from satellite navigation to power transmission and cellular communication is vulnerable to problems stemming from programs ignoring the extra second or adding it at different times.

Although the time will pass in the blink of an eye, Judah Levine, a physicist at the National Institute of Standards and Technology in Boulder, Colo., predicts the change will make him a very busy man starting about 5 p.m. Mountain Time. As part of the institute's Time and Frequency Division, he'll be helping to work out the bugs that follow.

"There's always somebody who doesn't get it right," Levine said. "It never fails."

Britons seemed less concerned about the remote prospect of having tea at 3 a.m. than the notion of leaving a France-based body in control of the world's time.

"I think there's some kind of historical pride we might feel in Britain about Greenwich being the point around which time is measured," 50-year-old telecoms executive Stephen Mallinson said as he waited to board a Eurostar train for Paris at London's St. Pancras Station.

"But in practice, does it make a difference? No."

At the Royal Observatory, 53-year-old homemaker Susie Holt was adjusting her wristwatch to match the digital display above the meridian. She said it would be a pity if GMT were made obsolete. Her daughter, 15-year-old Kirsty, was more forthright.

"We don't want the French to control time," she said. "They might get it wrong or something."

Meanwhile, Elisa Felicitas Arias, a scientist at the International Bureau of Weights and Measures, which computes atomic time at a facility outside Paris, has been busy lobbying to scrap the leap seconds that have given the 17th century Royal Observatory pride of place.

"GMT is out of date," she sniffed.

She said she has been garnering considerable support, with the International Telecommunications Union - the arbiter of international time standards - considering a vote on a switch as early as next year, with a 2018 target to implement it.

The U.S., France, Germany, Italy, and Japan were all on board, she said.

But David Rooney, the Royal Observatory's curator of time, defended leap seconds, saying they give everyone "the best of both worlds."

The arrangement, he said, allows satellites, physicists, and high-frequency traders to benefit from the accuracy of atomic time while keeping our clocks consistent with the position of the sun in the sky - and with GMT.

The American Astronomical Society is officially neutral on the proposal to switch to atomic time, which is calculated based on readings from more than 200 atomic clocks maintained across the world.

Perhaps predictably, Britain's Royal Astronomical Society has come out in favor of conserving leap seconds. While spokesman Robert Massey said star-watchers could cope no matter what happened, he urged caution on such an important change.

"It's not just a matter for the telecommunications industry to tell everybody to get rid of the leap second," Massey said. "It would be a big cultural change at the very least. Abandoning the connection between time and solar time is really a big shift."

Check out article at The Advocate.

I'm on the fence on this one... scientific accuracy is important, but I kinda like that time matches solar time. Guess we'll have to see how this argument plays out over the next few years.

Anyway... Please everyone remember to be safe and responsible tonight... and enjoy the celebrations!

Space Shuttles For Sale!!!

Space Shuttle Atlantis

Space Shuttle Discovery

Space Shuttle Columbia

Space Shuttle Atlantis riding a Boeing 747 Shuttle Carrier Aircraft (SCA)

Need that perfect gift for the space buff in your life?
Got 129 million cu ft of spare hangar space?
Then has NASA got a deal for you: Once the space shuttle fleet retires,
probably by 2010, the shuttles will be ready for purchase.
But even for the Smithsonian's National Air and Space Museum,
the shuttles come at a hefty price—about $42 million each!

Earlier this week the space agency issued a Request for Information (RFI) to educational institutions, museums, and "other organizations" in an attempt to sell off the remaining space shuttles in 2010. The estimated total for tax, tags and freight is $42 million. According to NASA, the RFI will "gauge the level and scope of interest of U.S. organizations in acquiring … orbiters and other major flight hardware."

The agency hopes to find homes for two of the three orbiters; Discovery is already earmarked for the Smithsonian's National Air and Space Museum. By law, the institution has something akin to a rights-of-first-refusal agreement with NASA that allows it first crack at space memorabilia once the government is done with it.

Discovery's long, active history makes it a logical choice for the Smithsonian. The third of NASA's winged spaceships and the oldest working orbiter, Discovery was deployed for the Hubble Space Telescope on mission STS-31 in April 1990, carried the 77-year-old John Glenn back into space in 1998, and was twice NASA's return-to-flight spacecraft—after the Challenger disaster in 1986 and the Columbia explosion five years ago. While Enterprise, the shuttle built for test flights, anchors the Smithsonian's space collection at the Steven F. Udvar-Hazy Center near Dulles airport in Virginia, the museum has long wanted to replace it with an operational orbiter. "To have any flown orbiter would be wonderful," says Valerie Neal, the Smithsonian's curator of the human spaceflight collection. "The Smithsonian tries to acquire the oldest or first-flown aircraft—so up until 2003, we'd hoped it would be Columbia. Now, of course, Discovery would be a perfect fit."

But that history comes with a hefty price tag—even for the internationally renowned Smithsonian. "We were in a different era then, where we had no eBay and people who were looking to make money off of artifacts," NASA spokesman Michael Curie told CollectSpace, a Web site devoted to space memorabilia. "So it was to everyone's advantage to try to provide them to those who might display them." NASA makes an important distinction: The $42 million isn't to buy an orbiter, but to prepare it for public presentation—nearly $30 million goes to "safeing" the craft (removing the fuel systems and other environmental hazards), approximately $8 million goes to display preparation and the final $6 million or so is spent on transportation and installation. Technically, the agency says, the cost is compensation for shipping and handling.

Industry observers also suggest that the cash-strapped space agency is grabbing every dollar it can find for the over-budget Constellation Program. In August, budget constraints forced NASA to scrap plans to have the shuttle's replacement, Orion, ready by 2013. The orbiters should be available Sept. 30, 2011, according to the RFI, and they should be ferried to their final destinations by May 31, 2012—where they will likely remain for a long time, since the agency is also decommissioning the 747 that is used to haul the spacecraft. "In the past, sometimes we have paid for this sort of 'shipping and handling,'" Neal says, "but this is unprecedented in terms of the cost involved. We're thrilled to have an orbiter designated for us, but we'll have to resolve the cost matter. Luckily, it's not like we have to come up with the money in 90 days."

CAMBRIDGE, England — Most clocks just tell time. Not the newly unveiled clock at Corpus Christi College in Cambridge, which aims to disorient and dazzle, to remind people of their own mortality and to pay tribute to one of the most famous watchmakers of all time.

No wonder it cost more than 1 million pounds (US$1.8 million) to build and drew the attention of famed cosmologist Stephen Hawking, who formally unveiled the masterwork Friday.

This clock blasts away all preconceptions about timepieces. For one thing, it has no hands. And it is specially designed to run in erratic fashion, slowing down and speeding up from time to time.

The "Corpus clock" is the brainchild of inventor John Taylor, who used his own money to build it, in part to pay homage to the genius of John Harrison, the Englishman who in 1725 invented the "grasshopper" escapement — a mechanical device that helps regulate a clock's movement.

Making a visual pun on the grasshopper image, Taylor has designed a fantasy version of a grasshopper at the top of the clock face, and uses this beast — with its long needle teeth and barbed tail — as an integral part of the clockworks.

Its jaws begin to open halfway through a minute, then snap shut at 59 seconds. The creature's eyes, usually a dull green, occasionally flash bright yellow.

The oversize grasshopper is called a chronophage, or "time eater."

"Time is gone, he's eaten it," Taylor said. "My object was simply to turn a clock inside out so that the grasshopper became a reality."

At the unveiling, Hawking predicted the creature atop the clock would become "a much-loved, and possibly feared, addition to Cambridge's cityscape."

The chronophage stands atop the clock face, which is four feet in diameter. It displays time with light — a light races around the outer ring once every second, pausing briefly at the actual second. The next ring inside indicates the minute, and the inner ring shows the hour.

The lights are light-emitting diodes, or LEDS, which are constantly on. The apparent motion is regulated mechanically through slots in moving discs.

Weirdly, the pendulum slows down or speeds up. Sometimes it stops, the chronophage shakes a foot, and the pendulum moves again. Because of that, the time display may be as much as a minute off, although it swings back to the correct time every five minutes.

"There are so many expressions in everyday life about time going fast, time going slow and time standing still. Your life is not regular, it's relative to what's going on," Taylor said.

"This is the first clock in the world that does not set out to show accurate time," Taylor said.

He noted Albert Einstein's observation: "When a man sits with a pretty girl for an hour, it seems like a minute. But let him sit on a hot stove for a minute and it's longer than any hour. That's relativity."

On Taylor's clock, the hour is tolled not by a bell or a cuckoo, but by the clanking of a chain that falls into a coffin, which then loudly bangs closed.

"I'm in my early 70s," Taylor told The Associated Press in a telephone interview. "When you're a young person you think there is plenty of time. The sound was to remind me of my mortality."

The clock is the showpiece of Corpus Christi's new library, also a gift from Taylor. His wealth comes from inventing controls for electric tea kettles, inventions which he estimates are used 1 billion times a day around the globe.

Taylor is intrigued by making the ordinary interesting.

"Clocks are boring. They just tell the time, and people treat them as boring objects," he added. "This clock actually interacts with you."

Big Bang Machine!

Large Hadron Collider Successfully Completes First Test

Large Hadron Collider

Large Hadron Collider Start-up

The God Particle could be found by the Large Hadron Collider

Fictional Anti-Scientific Propaganda - Cool Artwork Tho!
The sky is falling! Quick, get under a blanket!

The world's largest particle collider successfully completed its first major test by firing a beam of protons all the way around a 17-mile tunnel Wednesday in what scientists hope is the next great step to understanding the makeup of the universe.

After a series of trial runs, two white dots flashed on a computer screen indicating that the protons had traveled the full length of the $3.8 billion Large Hadron Collider.

The startup was eagerly awaited by 9,000 physicists around the world who now have much greater power than ever before to smash the components of atoms together in attempts to see how they are made.

The organization, known by its French acronym CERN, fired the protons — a type of subatomic particle — around the tunnel in stages, several miles at a time.

Now that the beam has been successfully tested in clockwise direction, CERN plans to send it counterclockwise. Eventually the two beams will be fired in opposite directions with the aim of smashing together protons to see how they are made.

"The beam is the size of a human hair," Paola Catapano, a spokeswoman for the host European Organization for Nuclear Research said after the protons were fired into the accelerator below the Swiss-French border at 9:32 a.m. (3:32 a.m. EDT).

It'll be months before any usable data comes out from the experiments, but the so-called "Big Bang machine" already has physicists salivating at the prospect of unlocking the mysteries of the universe — and many other people worried it'll create a black hole or strange self-replicating particle that will gobble up the Earth.

Professor Stephen Hawking, easily the world's most renowned living physicist, came down squarely in the "it's a good thing" camp Tuesday in a interview with BBC Radio: "Whatever the LHC finds, or fails to find, the results will tell us a lot about the structure of the universe."

The researchers' top aim is to find the Higgs boson, a sub-subatomic particle that's essential to the so-called Standard Model of nuclear physics, but which has never been seen.

Previously unknown particles are also expected to pop up, if only for a millionth of a second, from the high-energy collisions of protons and antiprotons.

A pair of Russian scientists even think the LHC would be the world's first time machine, and that we should expect visitors from the future to arrive soon after it goes into operation.

For that, $10 billion dollars has been spent to build the machine, the largest supercollider on Earth ever since the project to build an even larger ring in Texas was canceled in 1993.

But the very fact that it would create unknown particles, as well as incredibly dense microscopic black holes that would almost instantly evaporate, has raised many fears.

"It's nonsense," CERN chief spokesman James Gillies told the Associated Press.

A columnist on Wired magazine's Web site said that "the likelihood of these black holes becoming the more well-known kind of black hole is nearly nonexistent."

Brian Cox, a glamorous particle physicist who literally was once a rock star, told London's Daily Telegraph that he and his colleagues had been receiving death threats.

He then bluntly characterized anyone who feared the LHC would destroy the world with an unprintable term for a female body part.

That hasn't stopped several people, including a former nuclear engineer from Hawaii and a German biochemist, from speaking out against the project.

"Someone will spot a light ray coming out of the Indian Ocean during the night and no one will be able to explain it, retired Professor Otto Roessler told London's Mail on Sunday. "Very soon the whole planet will be eaten in a magnificent scenario — if you could watch it from the moon. A Biblical Armageddon. Even cloud and fire will form, as it says in the Bible."

"The compression of the two atoms colliding together at nearly light speed will cause an irreversible implosion, forming a miniature version of a giant black hole," reads a lawsuit filed in March in U.S. District Court in Honolulu by Walter L. Wagner and a Spanish colleague, Luis Sancho.

The case, in which Wagner and Sancho demand that the LHC stop operations until an independent safety review is conducted, is still pending.

Wagner first became famous a decade ago when he filed suit against the opening of the smaller Relativistic Heavy Ion Collider on Long Island, claiming it too would destroy the world when it started up in 2000.

Public reaction, true to form, has been mixed.

"This reminds me of the Millennium Bug! I love hysteria — it makes me laugh and I need a good laugh," said "Johan of Brisbane" in the comments to an Australian News Corp story.

Best of all was the posting on the same page by "KnowerOfAll": "Chuck Norris doesn't look for God Particles — he creates them."

Gillies told The Associated Press that the most dangerous thing that could happen would be if a beam of protons at full power were to go out of control, and that would only damage the collider itself and burrow into the rock around the tunnel.

Full power is probably a year away.

"On Wednesday, we start small," Gillies said. "What we're putting in to start with is one single low-intensity bunch at low energy and we thread that around. We get experience with low-energy things and then we ramp up as we get to know the machine better."

Huge amounts of data will pour in — so big that the lab's computers can't sift through it all. So scientists, who will monitor the experiment at above-ground control centers, have devised a way to share the load among dozens of leading computing centers worldwide.

The result is the "LHC Grid," a network of 60,000 computers to analyze what happens when protons are hurled at each other. That computing power is needed if scientists are to find what they are looking for among the mountains of data.

"You can think of each experiment as a giant digital camera with around 150 million pixels taking snapshots 600 million times a second," said CERN's Ian Bird, who leads the grid project.

Sophisticated filters discard all but the most interesting data, still leaving some 15 petabytes to be analyzed. That's enough to fill 2 million DVDs.

The data will be sent to 11 top research institutions in Europe, North America and Asia, and from there to a wider network of 150 research facilities around the world for scrutiny by thousands of researchers.

Collaborating on such a large project has proved invaluable, said Ruth Pordes, executive director of the Open Science Grid at Fermilab in Chicago. The U.S.-government funded project is among the major contributors to the grid.

"We are doing things that are at the boundaries of science," Pordes said. "But the technologies, the methods and the results will be picked up by industry."

Even if the LHC experiment doesn't yield answers to the cosmic questions, historians may one day see it as a key step in developing networked computing.

It wouldn't be the first time that has happened at CERN. In 1990, young British researcher Tim Berners-Lee created a computer-based system for sharing information with colleagues around the world.

He called it the World Wide Web.

Now, that's some exciting science! So exciting that it has captured the imaginations of people around the world!

Even Google got in on the act!Google features the Large Hadron Collider start-up

EA Sports Video Game Testing Center coming to LSU!

Electronic Arts Inc. eventually to hire 220 people at facility

EA Sports video game testing center coming to LSU

Rarely has recruiting a new company with a $6 million yearly payroll created such a buzz in Baton Rouge, but it’s the kind of jobs and the potential for keeping young people excited about staying in Louisiana that animated Wednesday’s announcement of a video game testing center coming to LSU.

Electronic Arts Inc.’s center at LSU’s South Campus on GSRI Avenue eventually will hire 220 people, 200 of whom will form a part-time platoon of students doing the heavy lifting on games like EA’s 20-year-old Madden NFL franchise, its Tiger Woods PGA Tour game and its NCAA Football series to make sure they’re consumer-ready.

Over the next decade, Gov. Bobby Jindal and economic development Secretary Stephen Moret envision EA’s Baton Rouge presence growing to higher-paying jobs for professionals who actually develop the video games, something that now takes place for EA largely in Orlando, Fla., and Vancouver, British Columbia.

If Baton Rouge reaches that zenith, construction of a digital research complex for kindred companies could result on LSU’s 200-acre South Campus area, Moret said.

“Ladies and gentlemen, with EA Sports this place definitely is more cool today than it was yesterday,” Adam Knapp, the Baton Rouge Area Chamber’s Generation X chief executive, told a Capitol audience at Wednesday’s announcement. “We have some investors (at the chamber) who believe and dream that the Baton Rouge area can be cool — and it is.”

Among the noteworthy Baton Rouge credentials cited by EA leaders in their location decision is this stunner: Not only is Louisiana’s obsession with LSU football and other sports not a negative as is often assumed by critics of the state’s higher education priorities, but the sports obsession is a huge plus, because the testers need to be savvy about the games they play for a living at EA.

“Is it fun? Does it have the right feel? Is it too hard? Is it too easy” are among the questions EA employees will answer at LSU, where Southern University and Baton Rouge Community College students are expected to fill the testing ranks as well, said Dave Steele, EA’s senior director of quality assurance.

“Because of the sports knowledge here, people can look at a football game and have the skills needed to test functions,” he said. “They still have to have a feel for the game. You’re down by less than a touchdown with less than two minutes to go on fourth down — what do you do? That’s really one of the reasons we wanted to come to Baton Rouge.”

The company also benefits from Louisiana’s offer of a 20 percent tax credit against state income tax liability, credits that can be claimed by the company or sold to a third-party for a cash advance.

All told, EA’s incentives for bringing the testing center to Baton Rouge will be worth about $14 million in the next decade, including payroll tax credits through the state’s Quality Jobs program.

Jindal said EA’s recruitment is invaluable for what it will mean to building the digital industry in the state, but it’s a good deal on the bottom line alone for this project.

“The state Department of Economic Development really looks at a 10-year return on investment as a good deal,” the governor said. “Within five years, we will get our return on investment. We look at this as the first step toward a much larger and bigger relationship with EA Sports.”

Simon Carless, publisher of Game Developer magazine, agreed that EA’s site selection represents a coup for Louisiana that could generate many more digital media gains.

It’s unusual for a global video game software company to open a testing-only center, which leads to the conclusion that actual video-game development business from EA could be within Baton Rouge’s reach, he said.

“I think what states struggle to do is get large-name publishers to set up offices in their area,” Carless said. “Electronic Arts is the world’s largest publisher, so I think it’s important if you can get someone like that. I think it’s definitely a positive introductory step, but it’s also important for individual area to reach a critical mass of game production or development before you can really get an ecosystem there, if you will.”

So far, three significant game developers have emerged in Baton Rouge: Founded by Southern University engineering graduate and former Motorola executive Jacqueline Beauchamp, Nerjyzed Entertainment LLC has published “Black College Football: The Experience”; Yatec LLC will publish its third major game, “Say N Play,” with voice recognition software late this year; and a Resurgent Entertainment LLC unit publishes the “Enigma: Rising Tide” war game.

“The industry will not develop overnight in Louisiana,” Redman said by e-mail Wednesday. “We said that back in 2005, but a couple of small companies every few months add up, and the synergy with Louisiana’s film industry will only become more apparent. … With EA, Louisiana has an enormous win to hold up and show to the world.”

Excellent news coming out of LSU! That's exactly the kind of thing we needed here! Not to mention... What a kick-ass job that would be!!!

NASA Celebrates 50 Years!

The Space Race

After the Soviet space program's launch of the world's first human-made satellite (Sputnik 1) on 4 October 1957, the attention of the United States turned toward its own fledgling space efforts. The U.S. Congress, alarmed by the perceived threat to U.S. security and technological leadership (known as the "Sputnik crisis"), urged immediate and swift action; President Dwight D. Eisenhower and his advisors counseled more deliberate measures. Several months of debate produced an agreement that a new federal agency was needed to conduct all non-military activity in space.

Explorer 1, officially Satellite 1958 Alpha, was the first Earth artificial satellite of the United States, having been launched at 10:48pm EST on 31 January 1958.

On 29 July 1958, President Dwight D. Eisenhower signed the National Aeronautics and Space Act, establishing the National Aeronautics and Space Administration (NASA). When it began operations on 1 October 1958, NASA consisted mainly of the four laboratories and some 80 employees of the government's 46-year-old research agency, the National Advisory Committee for Aeronautics (NACA). A significant contributor to NASA's entry into the Space race was the technology from the German rocket program, led by Wernher von Braun, who became a naturalized citizen of the United States after World War II. He is today regarded as the father of the United States space program. Elements of the Army Ballistic Missile Agency (of which von Braun's team was a part) and the Naval Research Laboratory were incorporated into NASA.

NASA's earliest programs involved research into human spaceflight and were conducted under the pressure of the competition between the U.S. and the USSR (the Space Race) that existed during the Cold War. Project Mercury, initiated in 1958, started NASA down the path of human space exploration with missions designed to discover simply if man could survive in space.

On May 5, 1961, astronaut Alan Shepard—one of the seven Project Mercury astronauts selected as pilot for this mission—became the first American in space when he piloted Freedom 7 on a 15-minute suborbital flight. John Glenn became the first American to orbit the Earth on 20 February 1962 during the 5 and a quarter-hour flight of Friendship 7.

Once the Mercury project proved that human spaceflight was possible, Project Gemini was launched to conduct experiments and work out issues relating to a moon mission. The first Gemini flight with astronauts on board, Gemini 3, was flown by Gus Grissom and John Young on 23 March 1965. Nine other missions followed, showing that long-duration human space flight was possible, proving that rendezvous and docking with another vehicle in space was possible, and gathering medical data on the effects of weightlessness on human beings.

Apollo program

The Apollo program was designed to land humans on the Moon and bring them safely back to Earth. Apollo 1 ended tragically when all the astronauts inside died due to fire in command module during an experimental simulation. Because of this incident, there were a few unmanned tests before men boarded the spacecraft. Apollo 8 and Apollo 10 tested various components while orbiting the Moon, and returned photography. On July 20, 1969, Apollo 11, landed the first man on the moon, Neil Armstrong. Apollo 13 did not land on the Moon due to a malfunction, but did return photographs. The six missions that landed on the Moon returned a wealth of scientific data and almost 400 kilograms of lunar samples. Experiments included soil mechanics, meteoroids, seismic, heat flow, lunar ranging, magnetic fields, and solar wind experiments.

Skylab

Skylab was the first space station the United States launched into orbit. The 75 tonne station was in Earth orbit from 1973 to 1979, and was visited by crews three times, in 1973 and 1974. Skylab was originally intended to study gravitational anomalies in other solar systems, but the assignment was curtailed due to lack of funding and interest. It included a laboratory for studying the effects of microgravity, and a solar observatory. A Space Shuttle was planned to dock with and elevate Skylab to a higher safe altitude, but Skylab reentered the atmosphere and was destroyed in 1979, before the first shuttle could be launched, landing over parts of Western Australia and the Indian Ocean, with some fragments being recovered.

Apollo-Soyuz

The Apollo-Soyuz Test Project (or ASTP) was the first joint flight of the U.S. and Soviet space programs. The mission took place in July 1975. For the United States of America, it was the last Apollo flight, as well as the last manned space launch until the flight of the first Space Shuttle in April 1981.

Shuttle era

The Space Shuttle became the major focus of NASA in the late 1970s and the 1980s. Planned to be a frequently launchable and mostly reusable vehicle, four space shuttles were built by 1985. The first to launch, Columbia, did so on April 12, 1981.

The shuttle was not all good news for NASA — flights were much more expensive than initially projected, and the public again lost interest as missions appeared to become mundane until the 1986 Challenger disaster again highlighted the risks of space flight. Work began on Space Station Freedom as a focus for the manned space program, but within NASA there was argument that these projects came at the expense of more inspiring unmanned missions such as the Voyager probes.

Nonetheless, the shuttle launched milestone projects like the Hubble Space Telescope (HST). The HST is a joint project between NASA and the European Space Agency (ESA), and its success has paved the way for greater collaboration between the agencies. The HST was created with a relatively small budget of $2 billion but has continued operation since 1990, delighting both scientists and the public. Some of its images, such as the groundbreaking Hubble Deep Field, have become famous.

In 1995 Russian-American interaction resumed with the Shuttle-Mir missions. Once more an American vehicle docked with a Russian craft, this time a full-fledged space station. This cooperation continues to today, with Russia and America the two biggest partners in the largest space station ever built – the International Space Station (ISS). The strength of their cooperation on this project was even more evident when NASA began relying on Russian launch vehicles to service the ISS during the two year grounding of the shuttle fleet following the 2003 Columbia disaster.

Costing over one hundred billion dollars, it has been difficult at times for NASA to justify the ISS. The population at large has historically been hard to impress with details of scientific experiments in space, preferring news of grand projects to exotic locations. Even now, the ISS cannot accommodate as many scientists as planned.

During much of the 1990s, NASA was faced with shrinking annual budgets due to Congressional belt-tightening in Washington, D.C. In response, NASA's ninth administrator, Daniel Goldin, pioneered the "faster, better, cheaper" approach that enabled NASA to cut costs while still delivering a wide variety of aerospace programs (Discovery Program). That method was criticized and re-evaluated following the twin losses of Mars Climate Orbiter and Mars Polar Lander in 1999. Yet, NASA's shuttle program had made 116 successful launches as of December 2006.

The Space Shuttle Columbia disaster in 2003, which killed the crew of six Americans and one Israeli, caused a 29-month hiatus in space shuttle flights and triggered a serious re-examination of NASA's priorities. The U.S. government, various scientists, and the public all reconsidered the future of the space program.

NASA's future

NASA's ongoing investigations include in-depth surveys of Mars and Saturn and studies of the Earth and the Sun. Other NASA spacecraft are presently en route to Mercury and Pluto. With missions to Jupiter in planning stages, NASA's itinerary covers over half the solar system.

Managed by the NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, the Phoenix mission was launched on August 4, 2007. It will search for possible underground water courses in the northern Martian pole. This lander revives much of its experiments and instrumentation from the failed 1999 Mars Polar Lander, hence its name. An improved and larger rover, Mars Science Laboratory, is under construction and slated to launch in 2009. On the horizon of NASA's plans are two possibilities under consideration for the Mars Scout 2013 mission.

The New Horizons mission to Pluto was launched in 2006 and will fly by Pluto in 2015. The probe received a gravity assist from Jupiter in February 2007, examining some of Jupiter's inner moons and testing on-board instruments during the fly-by.

Vision for space exploration

On January 14, 2004, ten days after the landing of the Mars Exploration Rover Spirit, US President George W. Bush announced a new plan for NASA's future, dubbed the Vision for Space Exploration. According to this plan, mankind will return to the Moon by 2018, and set up outposts as a testbed and potential resource for future missions. The Space Shuttle will be retired in 2010 and Orion will replace it by 2014, capable of both docking with the ISS and leaving the Earth's orbit. The future of the ISS is somewhat uncertain — construction will be completed, but beyond that is less clear. Although the plan initially met with skepticism from Congress, in late 2004 Congress agreed to provide start-up funds for the first year's worth of the new space vision.

Hoping to spur innovation from the private sector, NASA established a series of Centennial Challenges, technology prizes for non-government teams, in 2004. The Challenges include tasks that will be useful for implementing the Vision for Space Exploration, such as building more efficient astronaut gloves.

Moon base

On December 4, 2006, NASA announced it was planning to build a permanent moon base. NASA Associate Administrator Scott Horowitz said the goal was to start building the moonbase by 2020, and by 2024, have a fully functional base, that would allow for crew rotations like the International Space Station. Additionally, NASA plans to collaborate and partner with other nations for this project.

Man on Mars

On September 28, 2007, NASA administrator Michael D. Griffin stated that NASA aims to put a man on Mars by 2037, and in 2057, "We should be celebrating 20 years of man on Mars."

Blue Angels Airshow

The Blue Angels - Pensacola Beach, Florida

Blue Angels #5 solos upside down over Pensacola Beach, Florida

Blue Angels fly Echelon over Pensacola Beach, Florida


The United States Navy's Navy Flight Demonstration Squadron, popularly known as the Blue Angels, was formed in 1946 and is the world's first officially sanctioned military aerial demonstration team, as well as the oldest currently flying aerobatics team.

The Blue Angels’ mission is to enhance Navy and Marine Corps recruiting efforts and to represent the naval service to the United States, its elected leadership and foreign nations. The Blue Angels serve as positive role models and goodwill ambassadors for the U. S. Navy and Marine Corps.

A Blue Angels flight demonstration exhibits choreographed refinements of skills possessed by all naval aviators. It includes the graceful aerobatic maneuvers of the four-plane Diamond Formation, in concert with the fast-paced, high-performance maneuvers of its two Solo Pilots. Finally, the team illustrates the pinnacle of precision flying, performing maneuvers locked as a unit in the renowned, six-jet Delta Formation.

The team is stationed at Forrest Sherman Field, Naval Air Station Pensacola, Florida, during the show season. However, the squadron spends January through March training pilots and new team members at Naval Air Facility El Centro, California.

The Blue Angels are scheduled to fly 66 air shows at 35 air show sites in the United States during the 2007-2008 season, as the team celebrates 20 years of flying the F/A-18 Hornet. Last season, more than 15 million spectators watched the Blue Angels perform. Since its inception in 1946, the Blue Angels have performed for more than 427 million fans.

Check out the Official Blue Angels website.

We headed back to Pensacola to catch the annual Blue Angels Airshow. Saturday rained out, so it was rescheduled for Sunday, July 13... but they didn't disappoint! If you've never seen the Blue Angels perform live, you don't know what you're missing! They're awesome every time you see them!

Flying Suirrel Suit?

Wingsuit Flying

Flying Squirrel

It sounds crazy, and it probably is: Skydive from 15,000 feet (4,600 meters) and land safely—without a parachute—wearing a getup that resembles a flying squirrel costume.

"It's pretty much considered impossible," said Maria von Egidy, a designer with Jii-Wings in Cape Town, South Africa.

Von Egidy isn't interested in trying the stunt herself. But she aims to design the first wingsuit that will help pull it off.

Wingsuits are jumpsuits with fabric panels between the arms and legs that enable skydivers to zoom around in freefall.

By angling the self-inflating, rigid "wings," pilots can turn, dive, or rocket forward.

What wearers can't do—at least not yet—is land safely without the aid of a parachute.

"In terms of downward speed, we're actually within the margin of safety there for landing," von Egidy said. "But of course the forward speeds are tremendous."

And therein lies the catch.

Terminal Velocity

If pushed from a high-flying plane, a naked human would fall to Earth at a terminal velocity—or maximum speed—of about 120 miles (190 kilometers) an hour.

A wingsuit doubles a person's surface area, slowing the descent rate to about 30 miles (50 kilometers) an hour, about the same as with a small parachute, von Egidy said.

The main problem with making a safe landing is that wingsuit pilots descend not only downward but also forward, propelled by the gliding action of their wings.

Forward speeds can top 75 to 90 miles (120 to 150 kilometers) an hour.

For now wingsuit pilots deploy a parachute at the end of their jumps to slow their descent for touchdown.

But a few pilots and designers have been exploring ways to set down on solid ground without the aid of a chute.

Some, like BASE (building, antennae, spans, and Earth) jumper Jeb Corliss of Malibu, California, are reportedly experimenting with landing gear or special surfaces.

Von Egidy has a different idea.

"We're trying to flare the suit without using landing gear [but] with aerodynamics," she said. "It's really a very simple solution in the end."

The designer won't discuss her plans in more detail, lest she divulge trade secrets. But she does say that the key to her concept is to create a forward brake at the right moment.

"Our design efforts are centered around solving that problem," she said.

Von Egidy's passion for the wingsuit might seem ironic, as she has never skydived at all, let alone jumped wearing one of her prototypes.

Instead she relies on a clutch of experienced skydivers around the world to test the suits and report on their performance.

"I don't have the luxury of actually experiencing it myself," von Egidy said. "So I have to rely on really good descriptions from [the testers]."

Danger Dives

Jean Potvin, a physics professor at St. Louis University in Missouri, analyzes parachute safety for the Parks College Parachute Research Group.

Potvin, a veteran skydiver who's logged more than 2,400 jumps, believes it's possible to land the right wingsuit without a parachute.

But, he says, the very high speeds involved and the potential for pilot error pose huge risks.

"It's something that's doable, but it's … fraught with danger," Potvin said.

Whether von Egidy's strategy will work remains to be seen. She says it will be another few months before a prototype can be safely tested in the air.

In the meantime, she and business partner Cate Turner will continue to subsidize their wingsuit work with income from their main business: Tailors of Tinseltown, which supplies costumes to South Africa's television and film industry.

As for her quest to design the first wingsuit to safely deliver a person to Earth, the South African says she harbors few doubts she will succeed.

"The preliminary ground tests are very positive," she said. "Everybody who knows what I'm doing believes in it. It's just a damn good idea that no one spotted."

CAPE CANAVERAL, Fla. — Shuttle Endeavour and a crew of seven blasted into orbit Tuesday on what was to be the longest space station mission ever, a 16-day voyage to build a gangly robot and add a new room that will serve as a closet for a future lab.

The space shuttle roared from its seaside pad at 2:28 a.m., lighting up the sky for miles around as it took off on a multinational flight involving Canada and Japan.

It was a rare treat: The last time NASA launched a shuttle at nighttime was in 2006. Only about a quarter of shuttle flights have begun in darkness.

"Good luck and Godspeed, and we'll see you back here in 16 days," launch director Mike Leinbach radioed to the astronauts right before liftoff.

"Banzai," replied Endeavour's commander, Dominic Gorie, using a Japanese exclamation of joy. "God truly has blessed us with a beautiful night here, Mike, to launch, so let's light them up and give Him a show."

They did. The shuttle took flight with a flash of light, giving a peach-yellow glow to the low clouds just offshore before disappearing into the darkness.

Shortly after liftoff, the astronauts had to deal with alert messages regarding their ship's steering thrusters. Then for unknown reasons, the cooling system had to be switched from the primary to backup line. NASA said it was looking into the problems.

Gorie and his crew face a daunting job once they reach the international space station late Wednesday night. The astronauts will perform five spacewalks, the most ever planned during a shuttle visit.

The launching site was jammed with Canadians and Japanese representing two of the major partners in the international space station.

The Canadian Space Agency supplied Dextre, the two-armed robot that was hitching a ride aboard Endeavour, while the Japanese Space Agency sent up the first part of its massive Kibo lab, a storage compartment for experiments, tools and spare parts.

Also on hand for the liftoff was a 19-member congressional delegation led by Rep. Nick Lampson, D-Texas, whose district includes Johnson Space Center in Houston. He is pushing for increased NASA funding.

For the first time since space station construction began nearly 10 years ago, all five major partners were about to own a piece of the orbiting real estate. The launch of the first section of Kibo, or Hope, finally propelled Japan into the space station action.

"Our Japanese people have been waiting for a very long, long time," said Yoshiyuki Hasegawa, the Japanese Space Agency's station program manager.

"With this flight I believe that we finally became a real partner of the (space station) project, not just one of the members on the list, after 20 some years of effort in the project," said Keiji Tachikawa, head of the Japanese Space Agency.

Work on the space station project began in the mid-1980s, with preliminary design work for Kibo (pronounced KEE'-boh) starting in 1990. Space station construction, however, was stalled over the years for various reasons, most recently the 2003 Columbia tragedy.

The main part of the Kibo lab will fly on the next shuttle mission in May, with the final installment, a porch for outdoor experiments, going up next year.

Altogether, the Japanese Space Agency has invested about $6.7 billion in the space station program, including a Kibo control center near Tokyo.

Canada's $200 million-plus Dextre, meanwhile, is designed to eventually take over some of the more routine outdoor maintenance chores from spacewalking astronauts.

Dextre, short for dexterous and pronounced like Dexter, will join the space station's Canadian-built robot arm, already in orbit for seven years.

In addition to working with their international payloads, Endeavour's astronauts will try out a caulking gun and high-tech goo on deliberately damaged shuttle thermal tile samples.

The test — part of NASA's ongoing post-Columbia safety effort — should have been performed last year, but was put off because of emergency space station repairs.

Astronaut Garrett Reisman will stay behind on the space station until June, swapping places with a Frenchman who accompanied Europe's Columbus lab into orbit in February.

A Japanese astronaut is also part of Endeavour's all-male crew.

Endeavour's countdown was the smoothest in years, officials said. Shortly after liftoff, however, the astronauts had to deal with a couple of problems that ended up being minor. They got alert messages for some of their ship's steering thrusters, but it turned out to be a bad electronics card. Then the primary cooling system failed, and they had to switch to the backup.

A cursory look at the initial launch images — fewer than usual because of the nighttime launch — showed only one significant loss of debris from the external fuel tank 83 seconds into the flight. But it appeared to miss the right wing.

In any event, Endeavour will be checked thoroughly in orbit for any potential damage, standard procedure ever since the loss of Columbia because of a foam strike.

"This is just a wonderful beginning to what's going to be a long and challenging mission for us," said LeRoy Cain, a shuttle manager who gave the final "go" for launch. "But we're really looking forward to it and we're ready to go, ready to get to work on orbit."

It is the second of six planned shuttle missions this year, all but one to the space station. NASA faces a 2010 deadline for finishing the station and retiring its shuttles.

The End is Near!

Coronal Mass Ejection

Scientist have nailed down how and when the Earth will cease to exist.

The sun will slowly expand into a red giant, pushing the Earth further out into space, but not far enough.

Our home planet will be snagged by the sun's outer atmosphere, gradually plunging to its doom inside the fiery stellar furnace.

"The drag caused by this low-density gas is enough to cause the Earth to drift inwards, and finally to be captured and vaporized by the sun," explains astronomer Robert Smith of the University of Sussex in southern England.

Previous projections had all figured that the Earth would avoid falling into the sun, even during our star's red-giant phase.

The good news: This won't happen for another 7.6 billion years.

The bad news: Life on Earth will end long before then.

In fact, we've only got a billion years left before the slowly expanding sun boils off the oceans and reduces our planet to an uninhabitable cinder, says Smith.

That may sound like a long time, but in fact life on Earth's been around a lot longer than that — a total of 3.7 billion years, according to the latest estimates.

For those first three billion years, true, we were nothing but pond scum. Still, the new figures indicate the long story of life on our fair blue-green planet may be entering its last act.

Is there any way our future descendants can save themselves? Why, yes, explains Smith.

He cites a recent study emanating from the University of California, Santa Cruz. It proposes taming an asteroid to swing by the Earth every few thousand years, slowly nudging the Earth into higher solar orbit, enough to outpace the sun's own outward growth.

"This sounds like science fiction," says Smith. "But it seems that the energy requirements are just about possible and the technology could be developed over the next few centuries."

Holy crap does that sound like a bad day!

Target Practice?

U.S. Officials Plan to Shoot Down Satellite

US Navy Aegis Combat System

SM-3 Launch from US Navy Aegis Cruiser

WASHINGTON — Taking a page from Hollywood science fiction, the Pentagon said Thursday it will try to shoot down a dying, bus-size U.S. spy satellite loaded with toxic fuel on a collision course with the Earth.

The military hopes to smash the satellite as soon as next week — just before it enters Earth's atmosphere — with a single missile fired from a Navy cruiser in the northern Pacific Ocean.

One of the main goals of the satellite's destruction is to prevent any sensitive equipment from falling into the wrong hands.

"We are worried about something showing up on e-Bay," defense and intelligence expert John Pike said, adding that breaking up the satellite's pieces lessens the chance that sensitive U.S. technology could wind up in Chinese hands.

"What they have to be worried about is that a souvenir collector is going to find some piece, put it on e-Bay, and the Chinese buy it," said Pike, who is director of the defense research group GlobalSecurity.org.

The dramatic maneuver may well trigger international concerns, and U.S. officials have begun notifying other countries of the plan — stressing that it does not signal the start of a new American anti-satellite weapons program.

Military and administration officials said the satellite is carrying fuel called hydrazine that could injure or even kill people who are near it when it hits the ground.

That reason alone, they said, persuaded President Bush to order the shoot-down.

"That is the only thing that breaks it out, that is worthy of taking extraordinary measures," said Gen. James Cartwright, vice chairman of the Joint Chiefs of Staff, during a Pentagon briefing.

He predicted a fairly high chance — as much as 80 percent — of hitting the satellite, which will be about 150 miles up when the shot is fired.

The window of opportunity for taking the satellite down, Cartwright said, opens in three or four days and lasts for about seven or eight days.

"We'll take one shot and assess," he said. "This is the first time we've used a tactical missile to engage a spacecraft."

Deputy National Security Adviser James Jeffrey discounted comparisons to an anti-satellite test conducted by the Chinese last year that triggered criticism from the U.S. and other countries.

"This is all about trying to reduce the danger to human beings," Jeffrey said. "Specifically, there was enough of a risk for the president to be quite concerned about human life."

There might also be unstated military aims, some outside the administration suggested.

Similar spacecraft re-enter the atmosphere regularly and break up into pieces, said Ivan Oelrich, vice president for strategic security programs at the Federation of American Scientists.

He said, "One could be forgiven for asking if this is just an excuse to test an anti-satellite weapon."

A key issue when China shot down its defunct weather satellite was that it created an enormous amount of space debris.

"All of the debris from this encounter, as carefully designed as it is, will be down at most within weeks, and most of it will be down within the first couple of orbits afterward," said Jeffrey. "There's an enormous difference to spacefaring nations in ... those two things."

He and others dismissed suggestions that this was simply an attempt by the U.S. to flex its muscles, and that officials were overstating the toxic fuel threat.

Left alone, the satellite would be expected to hit Earth during the first week of March. About half of the 5,000-pound spacecraft would be expected to survive its blazing descent through the atmosphere and would scatter debris over several hundred miles.

If the missile shot is successful, officials said, much of the debris would burn up as it fell. They said they could not estimate how much would make it through the atmosphere.

They said the largest piece that would survive re-entry would be the spherical fuel tank, which is about 40 inches wide — assuming it is not hit directly by the missile.

The goal, however, is to hit the fuel tank in order to minimize the amount of fuel that returns to Earth, Cartwright said.

A Navy missile known as Standard Missile 3 would be fired at the spy satellite in an attempt to intercept it just before it re-enters Earth's atmosphere.

It would be "next to impossible" to hit the satellite after that because of atmospheric disturbances, he said.

Known by its military designation US 193, the satellite was launched in December 2006. It lost power and its central computer failed almost immediately afterward, leaving it uncontrollable. It carried a sophisticated and secret imaging sensor.

Software associated with the Standard Missile 3 has been modified to enhance the chances of the missile's sensors recognizing that the satellite is its target. The missile's designed mission is to shoot down ballistic missiles, not satellites.

Other officials said the missile's maximum range, while a classified figure, is not great enough to hit a satellite operating in normal orbits.

"It's a one-time deal," Cartwright said when asked whether the modified Standard Missile 3 should be considered a new U.S. anti-satellite technology.

He said that if an initial shoot-down attempt fails, the military would have about two days to reassess and decide whether to take a second shot.

NASA Administrator Michael Griffin told reporters that analysis shows the hydrazine tank would survive a fall to Earth under normal circumstances, much as one did when the space shuttle Columbia crashed.

"The hydrazine which is in it is frozen solid, as it is now. Not all of it will melt," he said.

If the tank hits the ground it will have been breached because the fuel lines will have broken off and hydrazine will vent out, he said.

Jeffrey said members of Congress were briefed on the plan earlier Thursday and that diplomatic notifications to other countries were being made by the end of the day.

"It should be understood by all, at home and abroad, that this is an exceptional circumstance and should not be perceived as the standard U.S. policy for dealing with errant satellites," said House Armed Services Chairman Ike Skelton.

If you're interested in getting a look at this satellite before we blow it out of the sky, it will be easy to see with the unaided eye. Just go check out the Satellite US 192 page at Heavens-Above.com for more info. I'm kinda hoping I can catch a glimpse of the explosion... provided I don't get a close-up view of any falling debris!

Messenger reveals new side of Mercury!

Messenger's image of Mercury as it passes Venus

Messenger's first photo of Mercury - the side we've never seen before!

Mariner 10's image of Mercury - 1973

NASA Messenger - Mission to Mercury

January 16, 2008—The first of many planned images from NASA's MESSENGER spacecraft is showing astronomers a side of Mercury no one's ever seen before.

Mercury is tough to view from Earth, since it's so close to the sun. And when the Mariner 10 probe flew past the innermost planet in 1974 and 1975, only one side of the body was facing sunlight.

That's because Mercury rotates three times during every two orbits, so the same side of the planet is lit up every other time it is nearest to the sun—including during all of Mariner's flybys.

Added up, these factors have meant that although Mercury sits only about 57 million miles (92 million kilometers) away from Earth, for more than 30 years scientists have had almost no details about its other face.

But on Monday MESSENGER, the first mission to Mercury since the 1970s, snapped the first image of the "missing" half of the rocky world.

Among many new sights, the picture features the full Caloris Basin, a huge impact basin more than 620 miles (1,000 kilometers) across that sits on the border between the known and previously unknown regions of the planet.

More unprecedented images of the tiny planet are expected as the MESSENGER craft completes three flybys of Mercury before settling into orbit in March 2011.

From that point on, writes astronomer Phil Plait on the Bad Astronomy blog, "we'll get as many images of this tiny, hot, battered, dense and neglected planet as we can handle."

Awesome new photos! I can't wait to see the map of Mercury once Messenger gets settled into orbit!

Manned Asteroid Mission?

NASA Manned Asteroid Mission

NASA Manned Asteroid Mission

NASA Manned Asteroid Mission

Here we are, nearly eight years into the 21st century, and the most spectacular manned mission NASA can pull off is a trip to the International Space Station, a mere 210 miles above the Earth. Even the most ambitious part of NASA's current plans for human spaceflight involves visiting a celestial body we've already been to: the moon. Astronauts, space buffs and an unimpressed public hunger for space exploration that's more dramatic, more heroic, more new. Something like, say, landing astronauts on a distant rock hurtling through space at 15 miles per second.

That's exactly the kind of trip NASA has been studying. In fact, scientists at the space agency recently determined that a manned mission to a near-Earth asteroid would be possible using technology being developed today. The mission wouldn't be easy. A crew of two or three would spend months riding in a cramped spacecraft before reaching their barren, nearly gravity-free target. That such a mission is even being considered, though, says a lot about the versatility of NASA's next fleet of spacecraft and the ambitions the agency has for them. If nothing else, it's a signal that space exploration could soon get much more exciting.

The Allure of an Asteroid

This wouldn't be our first trip to an asteroid. We've been visiting them by proxy for years now, using unmanned space probes. In 2000 NASA's NEAR Shoemaker spacecraft arrived at 433 Eros, which a century earlier became the first near-Earth asteroid known to man; five years later, the Japanese Hayabusa probe touched down on asteroid 25143 Itokawa.

Yet unmanned probes have their limitations. NEAR Shoemaker and Hayabusa gathered a good deal of data, but we still don't know the exact composition and internal structure of the asteroids they visited. And although Hayabusa was designed to collect two small samples from Itokawa, it's doubtful the probe will actually have anything onboard when it returns in 2010.

Humans, however, could be much more effective. Unlike robots, we adapt to our environment in real time. "We spend weeks at a rock with a Mars rover, trying to determine what it is," says Rob Landis, an engineer at NASA's Johnson Space Center and one of the co-leaders of the mission feasibility study. "An astronaut could make that determination in a matter of seconds."

A human crew could travel across an asteroid more intelligently than a robot, making it easier to deploy scientific instruments, collect samples, and zero in on the areas of greatest interest. "No doubt, on a human mission we would characterize an asteroid better than we ever have," says Bruce Betts, director of projects for the Planetary Society.

Plenty of characterization needs to be done. While most asteroids are a safe distance from Earth (in an approximately 190-million-mile-wide expanse between Mars and Jupiter), Jupiter's gravitational tug and, less often, collisions between asteroids can kick these objects into orbits that pass uncomfortably close to Earth. The 270-meter-wide asteroid 99942 Apophis, for example, will pass within roughly 24,000 miles of Earth in 2029, and could come back for a direct hit in 2036.

And if we're to have any hope of deflecting asteroids, we need to know a lot more about them than we do now. First off: What, exactly, are they made of? Measurements taken by Hayabusa indicate that 40 percent of Itokawa's volume is empty space. If some asteroids are truly this porous, that's helpful information for any plan to destroy or deflect an Earth-bound object.

Averting the apocalypse isn't the only reason to study near-Earth asteroids, though. They could be floating gold mines for future deep-space expeditions. Preliminary observations suggest that some asteroids are rich in useful minerals and, better yet, frozen water—the most valuable resource a space traveler could hope to find. If water could be extracted from asteroids, it could not only be used for drinking, but also broken down into oxygen for breathing and hydrogen for rocket fuel. "It might be an ultimate way to get to Mars," Landis says.

Just image the resources that could be discovered and the knowledge that would be gained by this venture. Truly exciting stuff!

Earth-rise in HD!

HD image of Earth taken from Japan's satellite Kaguya, aka Selene

Selene's HD version of the famous Apollo photo: Earth-rise

Selene's HD image of the Earth setting on the moon

Selene's HD compilation of the Earth setting on the moon

The original Earth-rise - taken by William Anders
during the Apollo 8 mission to the Moon on December 24, 1968.

A Japanese moon probe has replicated the famous Apollo-era "Earth-rise" photograph with modern high-definition imaging.

The Kaguya spacecraft, also called Selene, has been orbiting 62 miles (100 kilometers) above the moon since Oct. 18.

The new Earth-rise image shows our blue world floating in the blackness of space. It is a still shot taken from video made by the craft's high-definition television (HDTV) for space.

A second image, taken from a different location in the lunar orbit, has been dubbed Earth-set. A related series of still images shows our planet setting beyond the lunar horizon.

In the Earth-set image, Earth appears upside-down; visible are Australia and Asia. A region near the moon's south pole is seen in the foreground.

The footage was taken Nov. 7 using equipment provided by the Japan Broadcasting Corporation (NHK).

The orbiter mission is run by the Japan Aerospace Exploration Agency (JAXA). Its first high-definition videos of Earth were sent back last month. The mission objectives are to obtain scientific data on the origin and evolution of the moon and to develop the technology for future lunar exploration.

Check out the article at Space.com.

Awesome images... I want to get my hands on that video! Congrats to JAXA on a successful mission, and thanks for sharing!

Spy-Bugs!

Realistic Dragonspy

Realistic Spyfly

Tiny Spybug

Ever wish you could be a "fly on the wall" at a closed-door meeting or to hear a foe’s secrets?

Enter the robobug.

Witnesses are buzzing about recent sightings of robotic-looking dragonflies seen at Washington and New York political events. And U.S. government and private agencies have admitted to striving for the spy technology, The Washington Post reports, though no one has confessed to deploying the bugged bugs.

Vanessa Alarcon saw them while working at an antiwar rally in Lafayette Square last month.

"I heard someone say, 'Oh my god, look at those,' " the college senior from New York recalled. "I look up and I'm like, 'What the hell is that?' They looked kind of like dragonflies or little helicopters. But I mean, those are not insects."

Out in the crowd, Bernard Crane saw them, too.

"I'd never seen anything like it in my life," the Washington lawyer said. "They were large for dragonflies. I thought, 'Is that mechanical, or is that alive?' "

That is just one of the questions hovering over a handful of similar sightings at political events in Washington and New York. Some suspect the insectlike drones are high-tech surveillance tools, perhaps deployed by the Department of Homeland Security.

Others think they are, well, dragonflies -- an ancient order of insects that even biologists concede look about as robotic as a living creature can look.

No agency admits to having deployed insect-size spy drones. But a number of U.S. government and private entities acknowledge they are trying. Some federally funded teams are even growing live insects with computer chips in them, with the goal of mounting spyware on their bodies and controlling their flight muscles remotely.

The robobugs could follow suspects, guide missiles to targets or navigate the crannies of collapsed buildings to find survivors.

The technical challenges of creating robotic insects are daunting, and most experts doubt that fully working models exist yet.

"If you find something, let me know," said Gary Anderson of the Defense Department's Rapid Reaction Technology Office.

But the CIA secretly developed a simple dragonfly snooper as long ago as the 1970s. And given recent advances, even skeptics say there is always a chance that some agency has quietly managed to make something operational.

"America can be pretty sneaky," said Tom Ehrhard, a retired Air Force colonel and expert in unmanned aerial vehicles who is now at the Center for Strategic and Budgetary Assessments, a nonprofit Washington-based research institute.

Robotic fliers have been used by the military since World War II, but in the past decade their numbers and level of sophistication have increased enormously. Defense Department documents describe nearly 100 different models in use today, some as tiny as birds, and some the size of small planes.

All told, the nation's fleet of flying robots logged more than 160,000 flight hours last year -- a more than fourfold increase since 2003. A recent report by the U.S. Army Command and General Staff College warned that if traffic rules are not clarified soon, the glut of unmanned vehicles "could render military airspace chaotic and potentially dangerous."

But getting from bird size to bug size is not a simple matter of making everything smaller.

Check out the article at Fox News or the original article at The Washington post.

Cool, I could use a few of those!

Seriously, let's just hope that these things don't get in the wrong hands... yeah, like they aren't already.

Just imagine how good the New England Patriots would be if Bill Belichick got his hands on one of those spybugs!

The Beep Heard Around the World

Sputnik I - The Beep Heard Around the World

Sputnik I Launch

Sputnik I Model

With a series of small beeps from a spiky globe 50 years ago Thursday, the world shrank and humanity's view of Earth and the cosmos expanded.

Sputnik, the first artificial satellite, was launched by the Soviets and circled the globe Oct. 4, 1957. The Space Age was born. And what followed were changes to everyday life that people now take for granted.

What we see on television, how we communicate with each other, and how we pay for what we buy have all changed with the birth of satellites.

Communications satellites helped bring wars and celebrations from thousands of miles away into our living rooms. When we go outside, weather satellites show us whether we need to carry an umbrella or flee a hurricane. And global positioning system satellites even keep us from getting lost on unfamiliar streets.

Sputnik gave birth to more than mere technology. The threat of a Soviet-dominated space spurred the U.S. government to increase tenfold money spent on science, education and research. Satellite pictures of Earth inspired an embryonic environmental movement.

Spy and communications satellites also kept the world at relative peace, experts say. Just last week, scientists used commercial satellite images to document human rights violations in Myanmar.

When Sputnik was launched, the public thought a space future would consist of gigantic space stations and colonies on the moon and other planets. The fear was warfare in space raining down on Earth.

"The reality is that the things we expected did not come to pass, and the things that we did not fathom changed our lives in so many ways that we cannot even envision a life that's different at this point," said Roger Launius, senior curator at the Smithsonian Institution's National Air and Space Museum.

America got a taste of that in May 1998. Just one communications satellite malfunctioned. More than 30 million pagers went silent. Credit card payment approvals didn't work. National Public Radio and CNN's Airport Television Network went off the air in some places.

"The civilization we live in today is as different from the one that we lived in the mid-1950s as the mid-1950s were from the American revolution," said Howard McCurdy, an American University public policy professor. "It's hard to imagine these things happening without space. I guess I could have a computer, but I wouldn't be able to get on the Internet."

All thanks to an 184-pound metal ball with spikes shot into space by a country that doesn't exist anymore.

"The launch of Sputnik actually triggered heightened interest among the American people, not only in space, but in science, mathematics and education," said White House science adviser John Marburger. "It also opened up people's eyes to the possibility that space could actually be used for something."

Check out the article at Fox News.

It's amazing the technology that hostility and competition can breed. Where would we be now if not for the World Wars and the Cold War? I don't think we could even imagine!

Sputnik was not the original plan by the Russians... they used rockets from their ICBM program and threw together the simple little sphere with a radio transmitter in an effort to beat the USA to space. The only thing that they actually accomplished was to show the world that it could be done and that they did it first, and to broadcast the "Beep Heard Around the World."

Lunar Ark - A Sanctuary for Civilization

The Sanctuary for Civilization

The Moon - Destination of the Lunar Ark

Lunar Ark - The Sanctuary for Civilization

The moon should be developed as a sanctuary for civilization in case of a cataclysmic cosmic impact, according to an international team of experts.

NASA already has blueprints to create a permanent lunar outpost by the 2020s.

But that plan should be expanded to include a way to preserve humanity's learning, culture, and technology if Earth is hit by a doomsday asteroid or comet, said Jim Burke of International Space University (ISU) in France.

An impact of the size that wiped out the dinosaurs hasn't happened since long before the rise of humans, he pointed out.

Yet scientists' expanding knowledge of asteroids and craters left throughout the solar system has created a consensus that Earth remains vulnerable to a civilization-crushing collision.

This calls for the creation of a space age Noah's ark, Burke said.

Lunar Ark

Humans are just beginning to send trinkets of technology and culture into space. NASA's recently launched Phoenix Mars Lander, for example, carries a mini-disc inscribed with stories, art, and music about Mars.

The Phoenix lander is a "precursor mission" in a decades-long project to transplant the essentials of humanity onto the moon and eventually Mars.

The International Space University team is now on a more ambitious mission: to start building a "lunar biological and historical archive," initially through robotic landings on the moon.

Laying the foundation for "rebuilding the terrestrial Internet, plus an Earth-moon extension of it, should be a priority," Burke said.

The founders of the group Alliance to Rescue Civilization (ARC) agreed that extending the Internet from the Earth to the moon could help avert a technological dark age following "nuclear war, acts of terrorism, plague, or asteroid collisions."

But the group also advocates creating a moon-based repository of Earth's life, complete with human-staffed facilities to "preserve backups of scientific and cultural achievements and of the species important to our civilization," said ARC's Robert Shapiro, a biochemist at New York University.

"In the event of a global catastrophe, the ARC facilities will be prepared to reintroduce lost technology, art, history, crops, livestock, and, if necessary, even human beings to the Earth," Shapiro said.

"The establishment of an ARC sanctuary would for the first time provide a compelling purpose for the colonization of space."

If the international lunar outpost of the 2020s expands into a colony and then a city, "it is possible that a whole new phase in civilization may develop—the branching of history into one stream on Earth and another on the moon," ISU's Burke added.

This "dual-world expansion" could be within reach by the end of this century, he said.

"Look at the last century, when we went from the Wright brothers to the Apollo missions—along with man's great expansion of his understanding of the cosmos."

Check out the article at National Geographic News.

What an exciting venture! I think that it's an excellent contingency plan for the preservation of our civilization... and yet another justification for the space program!

Spaceport America

Spaceport America - Flight at Dawn

Spaceport America - Inside the Terminal

Spaceport America - Cutaway View

GOLDEN, Colorado -- Architectural and engineering teams have begun shaping the look and feel of New Mexico's Spaceport America, taking the wraps off new images today that showcase the curb appeal of the sprawling main terminal and hangar at the futuristic facility.

Last month, a team of U.S. and British architects and designers had been recommended for award to design the primary terminal and hangar facility at Spaceport America - structures that symbolize the world's first purpose-built commercial spaceport.

When the 100,000 square-foot (9,290 square-meter) facility is completed -- the centerpiece of the world's first, purpose-built, commercial spaceport -- the structures will serve as the primary operating base for Sir Richard Branson's Virgin Galactic suborbital spaceliner, and also as the headquarters for the New Mexico Spaceport Authority.

The terminal and hangar facility will also provide room for aircraft and spacecraft, and Virgin Galactic's operations facilities, including pre-flight and post-flight facilities, administrative offices, and lounges. The spacious maintenance hangar can hold two White Knight Two carrier aircraft and five SpaceShipTwo spaceliners - vessels now under construction at Scaled Composites in Mojave, California.

Destination experience

The terminal and hangar facility are projected to cost about $31 million, and will provide a "Destination Experience" for visitors to Spaceport America. Virgin Galactic intends to sign a 20-year lease for approximately 84,000 square feet (7,803 square meters) in the building.

"The URS/Foster team presented us with a concept that blends sensitivity to the environment, cutting-edge technology and a stunning image and shape when viewed from high above," noted Kelly O'Donnell, chair of the New Mexico Spaceport Authority in a press statement last month.

The design chosen is a low-lying, striking bit of construction that uses natural earth as a berm, and relies on passive energy for heating and cooling, with photovoltaic panels for electricity and water recycling capabilities. A rolling concrete shell acts as a roof with massive windows opening to a view of the runway and spacecraft.

According to a press statement, the low-lying, organic shape resembles a rise in the landscape, and will use local materials and regional construction techniques.

"A careful balance between accessibility and privacy is achieved, as visitors and astronauts enter the building through a deep channel cut in the landscape," the statement noted. "The walls will form an exhibition area leading to a galleried level above the hangar that houses the spacecraft and on through to the terminal building.

Construction on the 100,000 square-foot hangar and terminal facility is scheduled to begin in 2008.

WOW... I can't wait to check this place out when it's finished! I think I'll take a wait-and-see attitude when it comes to space tourism. I'd like to have a destination other than "fly into space, enjoy the view and float around for a few minutes, fly home." Maybe these guys need to build a space station resort as the destination, then I'll go.

Cyber Security?

Cyber Security Threat

Richard Clarke remembers standing in the Oval Office and handing President George W. Bush a letter regarding what the nation should do to secure cyberspace.

"I think he signed it. I don't think he read it. I don't think he knows what it was," Clarke said during his keynote here in Las Vegas at the Black Hat security conference on Aug. 1.

Clarke is somebody whose advice Bush should have heeded.

Until his retirement in 2003, Clarke was a member of the Senior Executive Service, having served as an advisor to four presidents between 1973 and 2003.

He was the chief counter-terrorism advisor on the U.S. National Security Council for both the latter part of the Clinton administration through the early part of Bush's administration and the 9/11 attacks.

Serving with the Clinton administration, he toured the country for two years, collecting industry and academic intelligence on one crushingly important question: How do we secure cyberspace?

This is important. Within the coming 20 years, Clarke said, our soldiers will enter the battlefield with multiple IP addresses.

The Pentagon is already working toward what Clarke called net-centric warfare, part of which will be exoskeleton armor covered with interior and exterior sensors.

These exoskeletons will allow soldiers to literally have eyes in the back of their heads, to see around corners as robots fly ahead and beam back images to their visors, to lift weights at 5 to 10 times their normal capability due to exoskeletal servo-motors, and have their health monitored and their illness or fatigue medicated — again, automatically through the exoskeletal suit.

The Pentagon's vision of net-centric warfare relies on IP addresses, lots of them.

It's why the Pentagon is the only part of government now pushing for the next-generation Internet, IPv6, with its vast capacity for IP addresses, Clarke said.

But this all assumes that cyberspace is secure.

"It's not," Clarke said. "The chaos that goes on in cyberspace very day, I don't have to tell you about," he said to the audience of black, white and gray hackers.

"We are building more and more of our economy, our global economy, on the foundation of cyberspace 1.0," Clarke said. "The fundamental architecture hasn't changed since creation. And we still have secured very little" of that architecture, he said, including the very foundations of today's Internet's, DNS and PHP — themselves still not very secure.

We're also still running code from major vendors across the world that's "replete with errors, replete with errors people can use to hack into systems," Clarke said.

We still have no industry or academically generated standards to secure code, he added.

We still don't write secure code, either, he said, with high rates of errors commonplace.

We still don't authenticate much of cyberspace, either, he said.

We could also be using encryption far more than we do today, Clarke said — an omission evidenced by the loss of a laptop bearing the Social Security numbers of U.S. veterans.

"When some government laptop with the Social Security numbers of every veteran in the United States is stolen in Washington, we shouldn't have to worry about it; it should be encrypted. Databases should be encrypted," he said.

And, yet, they're not.

VoIP (Voice over IP) can be encrypted. With headlines about national security letters being abused by the FBI and other uses of surveillance, perhaps we should encrypt phone calls, Clarke suggested.

The United States also needs to adopt IPv6 "much more rapidly," Clarke said — not only because the Defense Department's plans rest on having IP address-loaded soldiers, but "because it also offers opportunity for security and for prioritization, which we don't have today. Think of how prioritization could improve disaster response in situations like 9/11 or Katrina, where communications channels get swamped immediately, barring emergency first responders from the prioritization they should have.

"And yet we're now planning disaster relief and other response based on cyberspace. On the Internet," Clarke said. "There's no way today to differentiate e-mail from someone to their grandmother or a packet with their vacation photos with that of [communications from a first responder in a disaster situation]."

The work needed to create an Internet infrastructure that could support a more secure, more rationalized cyberspace has unfortunately been starved of funding by a Congress, an administration and a society that just "doesn't get it," Clarke said.

"The Bush administration has systematically reduced the work necessary to secure cyberspace," he said.

"It's not because the answers aren't there," he said. "Or because it's a really hard problem. Sure it's a hard problem, but a lot can be done quickly. Two years we went around holding meetings, asking experts, asking industry, What should we do to secure cyberspace?"

Perhaps, instead of debating stem cell research, instead of debating whether evolution should be taught in schools, instead of surveilling citizens rather than terrorists, we should be having this crucial debate, Clarke said.

"The enemy is terrorists. The enemy is not citizens," he said.

The takeway from his talk: The enemy is an insecure cyberspace.

Scary stuff! One can only hope that the government and society recognize the threat and begin to act before it's too late!

Phoenix Mars Lander

Phoenix Mars Lander Launch - August 4, 2007

CAPE CANAVERAL, Fla. — A robotic dirt and ice digger blasted off Saturday, August 4th, 2007 on a 422 million-mile journey to Mars that NASA hopes will culminate next spring in the first ever landing within the red planet's Arctic Circle.

The unmanned Delta rocket carrying the Phoenix Mars Lander rose from its seaside pad at 5:26 a.m., exactly on time, and hurtled through the clear moonlit sky. It was easily visible for nearly five minutes, a bright orange speck in a spray of stars.

If all goes as planned — a big if considering only five of the world's 15 attempts to land on Mars have succeeded — the spacecraft will set down on the Martian Arctic plains on May 25, 2008, and spend three months scooping up soil and ice, and analyzing the samples in minuscule ovens and mixing bowls.

The Phoenix Mars Lander won't be looking for evidence of life on Mars but rather traces of organic compounds in the baked and moistened samples, which would be a possible indicator of conditions favorable for life, either now or once upon a time.

If organic compounds are present on Mars, they're more likely to have been preserved in ice. That's why NASA is aiming for the planet's high northern latitudes, where ice is almost certainly lurking just beneath the surface.

Only about six inches of soft red soil should cover the ice, and so the digger shouldn't have to probe too deeply. The ice is expected to be as hard as concrete, and a drill on the scoop will help gather enough frozen samples. Some dirt and ice samples will be baked and their vapors analyzed. Other soil samples will be mixed with onboard water and the muddy soup examined by onboard microscopes.

"We're really going there just to understand whether the conditions might have been hospitable for microbial life at some point," said the University of Arizona's William Boynton, lead scientist for the oven experiment.

Even if organic molecules pop up, they could be from incoming meteorites, Boynton noted. "It is important, I think, to keep in mind that we are just looking for organic molecules to see if the conditions are right that they could survive," he said, "and that we aren't really going to be making any inference about whether these molecules are indicative of life."

Mars landings are especially risky. Only five of the 15 U.S., Russian and European attempts have worked, all of them American successes beginning with the 1976 Viking touchdowns. Given those odds, the Phoenix team said it did everything possible to test for failures and will continue to do so as the spacecraft flies to Mars. The entire mission costs $420 million.

NASA has never attempted to land a spacecraft on Mars at such a high northern latitude. A lander intended for the red planet's South Pole went silent immediately upon arrival in 1999. That failure, combined with the loss of the companion Mars orbiter, prompted NASA to cancel a 2001 lander mission. The parts from that scrapped mission were used for Phoenix, thus its name, which alludes to the mythological bird that rises from its own ashes.

Phoenix should help pave the way for human visitors, especially if it confirms the presence of water ice in large amounts near the pole, said Michael Meyer, NASA's lead Mars scientist. That would be a tremendous resource, he noted. But if organic matter is indeed found, it could pose a dichotomy: "As Mars gets more interesting, you may not want to send humans right away until you learn out a little bit more about the red planet and find out whether or not life ever got started there."

Science fiction writer Kim Stanley Robinson, whose novel "Green Mars" is one of dozens of writings going up on a disk aboard Phoenix, is thrilled to see another robot headed to Mars.

The photos beamed back by recent Mars spacecraft "are just astonishingly precise compared to what I got to deal with when I was working on my books," he said. "It's like putting on glasses after you've been semi-blind all your life."

"I'm quite confident that humans will go to Mars and I do think it's important," Robinson said Friday. "When people get there, they'll be able to do on the ground what maybe 100 robotic missions would have been able to do."

This is so interesting! What's more, it brings us one step closer to understanding Mars and sending manned missions there in the future!

Transformers: The New Benchmark for Movie F/X!

Transformers

Transformers

Transformers

Transformers

More than 750 parts stretching a half-mile long. Some 350 engineers working round-the-clock. Thousands of rusty, old mechanic photos — clutch plates, transmissions, brake discs — spilling across the table. All for one beat-up Camaro? Sure doesn't sound like your average auto manufacturer.

"The idea is they're not fresh off the showroom floor," says Jeff White, the man charged with creating the yellow sports car and 13 others for a big new garage. He's right: They're supposed to look realer than that. And be from outer space. And turn into 30-ft. robots. And save the universe.

That's all in a day's work for the motor magicians at George Lucas's Industrial Light & Magic (ILM), who for the last two years have been juggling the limits of the possible (turning a real car into a fake robot and figuring out what the heck to put inside) and the demands of reality (studio budgets, GM sponsorship, the wrath of fanboys worldwide) to build the most painstaking — and maybe most believable — effects achievement in movie history: Transformers.

When it revs up at the box office this Fourth of July, Michael Bay's $150 million adaptation of the legendary 1980s cartoon and toy series will include nearly 50 so-called transformations. Hand-rendered metallic uncorkings of real-life cars, trucks and helicopters represented uncharted territory for the gooey-alien experts at ILM, each transformation taking six months to imagine and each re-engineering the way digital Hollywood does computer graphics imagery (CGI).

"How are we gonna get this thing from a car into the robot and back in a believable way?" White, the film's digital production supervisor, asked the Transformers crew in 2005, when, after their back-and-forth with toymaker Hasbro, the F/X plan consisted of little more than robot sketches and shiny new Hummers — and not much in between. "Of course, Michael Bay wants a lot of energy, he wants ninja-fighting warriors that can punch and put their arms over their heads and do all this crazy stuff," White says. "So we had to design these really complicated systems — how do all these systems match together and fly over each other to keep it looking real? And that was a huge challenge."

From Jar Jar Binks in the new Star Wars films to villains of the Pirates of the Caribbean trilogy, the modern CGI pipeline has tended to work from the ground up: Pre-build a creature, film it with a stand-in on set, then animate it to react, to actors such as Samuel L. Jackson or Johnny Depp, in postproduction. But after realizing that the simple route, with one transformation per Autobot or Decepticon, might not look robotic enough, Bay and Co. pulled a 280-terabyte U-turn.

ILM designed a backwards interface, moving the beginning of CGI production out of the hands of creature development and onto the desktops of the animators. By allowing animators to get the first crack at rigging control — the way a computer-generated character is built, the way it walks and rotates — ILM's IT team could develop software for custom transformations designed on the fly that might satisfy Bay's notorious flying camera angles. Click a button here, and a flatbed's brake light can pivot into an Optimus Prime punch. Set a control function there, and an alien jetfighter wing can cock into a Megatron claw for any of a half-dozen different scenes.

Optimus Prime has lips. Moving metal lips. The Autobot leader went to the grave in the original 1986 movie without ever having opened his voice box, but Bay hated the idea of action heroes wearing a mask. So he had ILM juice up each robot's jaws, eyes and metallic visage, from cartoony strobe light to winking, blinking, crackling Norelco blades.

But the most important finishing touch? Grease. Lots of it. Sure, stagehands dusted off the real Pontiac Solstice GXP before the cameras rolled, but digital painters at ILM were shading the doors and really mucking up each car's gearbox guts before they rolled up into robots. "Here we've got a car but we don't have any robots, so that's what made this project way harder than Pearl Harbor, where we had real planes to look at," says Ron Woodall, admitting that he painted some cars to look twice as dirty as their exteriors. "We don't have a target, and it's up to everyone's imagination."

Ultimately, that's the point of spending $150 million on car chases, explosions and millions of little CGI polygons: Drummed-up digital trickery is now at the level of turning the unreal into the real — as long as it doesn't seem too cheesy, and doesn't piss off too many fans. "Our goal is to please Michael Bay. He's got to answer to all the other folks," Benza says. "So top of the priority list? If it looks cool, that's where we start. That's the ultimate goal, then we can figure out ways to get the Chevy logo visible and the kind of signature things that the GM folks wanted in there. But I think ultimately even GM wanted Michael to have creative control over the coolness of the transformations."

What ends up on the silver screen this week is something that for once actually looks silver, justifiably chrome. Bay even had to send back one of the few non-CGI scale models made for the film — a painted fiberglass Bumblebee made for a scene when the Autobot savior is tied to train tracks — because it didn't look real enough. "It's been a struggle for all of us in this business to get the computer graphics looking as good as they are now, and I really do believe Transformers is a new high-water mark for making materials look good," says Farrar, the visual-effects supervisor and Bay's right-hand computer geek. "It's surprisingly complicated in the world of computer graphics to make objects look like what everybody in the world sees every day."

Check out the article at Popular Mechanics.

This was a totally awesome movie! Being a big fan of the Original Transformers in the 80's, I was worried that they would screw this one up... but it was great! The special effects were so realistic, I found myself immersed in the movie and actually believing that the people were talking to the robots. Way to go, Michael Bay and ILM!!!

New Planet Bonanza!

Planet Gliese 581a

HD 69830 Planets

Twenty-eight new planets have been discovered outside the solar system in the past year, scientists announced yesterday.

The new discoveries raise the total number of exoplanets—worlds that circle other stars—to 236.

Many of the discoveries were published in scientific journals over the past year.

Monday's announcement at a meeting of the American Astronomical Society in Honolulu, Hawaii, was the first time the finds were presented together to the public.

Most of the new planets are probably huge balls of gas, more like Jupiter than Earth.

But scientists say the increasing rate at which they're finding new exoplanets makes it almost certain that the galaxy is swarming with smaller, rocky, and potentially habitable worlds that have so far eluded detection.

"We're finally now getting a sense that our solar system is not a rarity," said Geoff Marcy, who led the California and Carnegie Planet Search team that made many of the discoveries.

"There are indeed tens of billions of planetary systems out there, no doubt some of them rocky Earths, lukewarm, and suitable for life."

Marcy, an astrophysicist at the University of California, Berkeley, spoke to National Geographic News from the Keck Observatory atop Hawaii's Mauna Kea, where many of the new exoplanets were first spotted.

Advanced Wobbles

Because exoplanets are too far away to be seen directly, the 28 new planets were discovered by looking for the so-called Doppler wobble among stars.

This technique is based on the idea that if an unseen planet orbits a star, its gravitational pull causes a slight "wobble" in the light wavelengths coming from that star.

In addition to revealing the 28 new planets, advances in this technique recently allowed a postdoctoral astronomer at the University of Geneva in Switzerland to pin down the size of a large exoplanet that was discovered almost two years ago by Marcy's team.

Finding Other "Earths"

Based on data gathered so far, of the more than 200 billion stars in the Milky Way galaxy, at least 10 percent are thought to have planetary systems, UC Berkeley's Marcy said.

And at least 30 percent of all stars that are known to host planets have more than one, scientists say.

"Many of them remind us of our home solar system," Marcy said.

"We're finding a lot of cases in which the larger planets—the Jupiters and the Saturns—orbit further from the star than the smaller planets, and that is in fact the case for our solar system," he said.

Among this year's exoplanet finds are at least four new multiple-planet star systems.

Astronomers are finding that stars harboring the most planets are those that are rich in heavier elements, such as silicon, oxygen, iron, and nickel.

This may give researchers a clue as to where to look for possible habitable worlds.

"It's those richer stars that we're focusing our attention on, because those heavy elements are the building blocks of rocky planets like our Earth," Marcy said.

After all, he said, "it's not just the planets that require the heavy elements, it's the organisms themselves, should any exist."

There are bound to be TONS of potential new homes for us... we just have to know where to look.

Robot Warfare!

Israeli VIPeR Combat Robot

Very few drones are built to kill. Even the missile-firing Predator UAV was originally designed for aerial reconnaissance, with some units later modified for combat duty. But for the Israeli-manufactured VIPeR (Versatile, Intelligent, Portable Robot), delivering firepower isn’t an afterthought — it’s practically job one.

Designed to act as a partner to dismounted troops in urban environments, the 9-in.-tall, 25-pound VIPeR can accept various sensor packages, including infrared cameras and software that maps buildings as the drone moves through them, as well as an explosives sniffer and a device that shoots jets of water to disarm bombs. But it also can open fire with a mini-Uzi submachine gun or release grenades from a 4-ft.-long robotic arm.

At just 18 in. wide, and equipped with innovative treads that change shape to help boost it over obstacles, the tiny drone can navigate cramped hallways and climb stairs to seek out targets. It can’t open fire autonomously, like South Korea’s Intelligent Surveillance & Security Guard Robot, essentially an armed guard tower that can target potential intruders.

VIPeR is remotely controlled via a harness and helmet-mounted display, with a human operator ultimately deciding whether to pull the trigger. According to its manufacturer, Elbit Systems, VIPeR will be deployed by Israel Defense Forces infantry after field testing.

A cool invention that will keep soldiers safe whilst killing enemies... let's just not try to make them "smart"... we all saw what happened in The Terminator!

In a whale-sized project, the world's scientists plan to compile everything they know about all of Earth's 1.8 million known species and put it all on one Web site, open to everyone.

The effort, called the Encyclopedia of Life, will include species descriptions, pictures, maps, videos, sound, sightings by amateurs, and links to entire genomes and scientific journal papers. Its first pages of information will be shown Wednesday in Washington where the massive effort is being announced by some of the world's leading institutions. The project will take about 10 years to finish.

"It's an interactive zoo," said James Edwards, who will be the encyclopedia's executive director. Edwards currently helps run a global biodiversity information system.

If the new encyclopedia progresses as planned, it should fill about 300 million pages, which, if lined up end-to-end, would be more than 52,000 miles long, able to stretch twice around the world at the equator.

Two foundations have given $12.5 million to pay for the first 2 1/2 years of the massive effort, but it will be free and accessible to everyone.

The pages can be adjusted so that they provide useful information for both a schoolchild and a research biologist alike, with an emphasis on encouraging "citizen-scientists" to add their sightings. While amateurs can contribute in clearly marked side pages, the key detail and science parts of the encyclopedia will be compiled and reviewed by experts.

"It could be a very big leap in the way we do science," said Cristian Samper, acting secretary of the Smithsonian Institution, one of seven museums, universities and labs to launch the encyclopedia. "This is a project that is so big, not even the Smithsonian, could do it by itself. It is a global effort."

For more than a decade, scientists have tried to compile even just a list of all species on Earth, but failed. It's been too complicated, too expensive and too cumbersome. This effort may succeed where the others have faltered because of new search engine technology, the scientists said.

Check out the article at Discovery News.

I can't wait until they get this project up and running... what an excellent resource this will be for everyone!

What interests me the most is the combination of un-editable encyclopedia quality information and user-based wiki-style areas for you and I to contribute to... all on the same page! No more will we have to worry if our information source has been tainted by one misinformed or biased user contribution... but at the same time, users will not be prohibited from adding to the database.

Think about it... one user sighting that is added to the site could effectively change the borders of that animal's range. For instance... I recently caught a snake in my yard and took a few photos (see above). I pulled the snake's photo up and went searching the Snakes of Louisiana website. Sure enough, I found what I was looking for: Texas Rat Snake. Funny thing, though... their range map shows the snake's range ending more than 50 miles west of me, on the other side of the Mississippi River! With the new Encyclopedia of Life website, the range map could be updated by the experts thanks to my sighting. Now, that's science that makes sense!

The Sun in 3D!

The first Stereo image of the sun - 2D

The first Stereo image of the sun - 3D
View image with 3D Glasses

NASA's Stereo Satellites

How the Stereo satellites work

April 23, 2007 — Break out those 3-D glasses and get ready to see the sun in a whole new light.

NASA released the first three-dimensional images of the sun ever compiled, a feat made possible by the agency's twin Solar Terrestrial Relations Observatory (STEREO) spacecraft.

Like a person's two eyes providing depth perception, the two spacecraft orbit the sun at a set distance from each other to offer a stereo view.

"The improvement with STEREO's 3-D view is like going from a regular x-ray to a 3-D CAT scan in the medical field," Michael Kaiser, STEREO project scientist at NASA's Goddard Space Flight Center, said in a press release.

Until now, 2-D images of our star (such as the one at top) have allowed scientists to see the sun's weather, but the flat views made it difficult to decipher the exact motion of solar eruptions and the distance they spanned.

Understanding the sun's physics is critical, scientists say, because especially strong events called coronal mass ejections create radiation storms that can disrupt satellites and radio communications and can even knock out power grids on Earth.

The new 3-D images (such as the one at bottom) will help researchers better track these ejections—like meteorologists tracking hurricanes—and thus predict when and where violent storms are headed.

"Previous imagery did not show the front of a solar disturbance as it traveled toward Earth, so we had to make estimates of when the storm would arrive," STEREO investigator Russell Howard of the Naval Research Laboratory told Space.com.

"These estimates were uncertain by a day or so. With STEREO, we can track the front from the sun all the way to Earth and forecast its arrival within a couple hours."

Check out the article at National Geographic News.

I broke out an old pair of 3D glasses and checked out the images... AWESOME! These satellites have delivered more than I expected they would when they were launched last year!

I'd be very interested to see images of Earth if they would develop Earth Stereo satellites!

Space-Plane Travel

NASA - Virgin Galactic X43b hypersonic space plane

X43 Mission Profile

X43 - Mach 7 Computational Fluid Dynamic

Virgin Galactic, the space tourism venture of billionaire entrepreneur Sir Richard Branson, is the first step toward hypersonic travel between Earth-based cities, according to a company executive.

Hypersonic speeds are greater than five times the speed of sound. An aircraft flying that fast could theoretically reach London from New York in less than an hour.

Virgin Galactic's space flights will accustom passengers to flying at the extreme altitudes likely necessary for hypersonic travel, said Alex Tai, the venture's chief operating officer.

"The experiential rides that we're providing with Virgin Galactic are the first rung, or the stepping stone, for us to use space for other activities," Tai said.

"And the first one of those we'd like to look at is point-to-point travel on the planet," he continued.

The venture will explore the possibility of hypersonic travel as part of a memorandum of understanding it signed last month with the U.S. space agency NASA.

"If Virgin's going to go off and build a high-speed transoceanic passenger service craft of some sort, NASA's of course very interested," said Dan Coughlin, NASA's lead for the Virgin Galactic agreement at the Ames Research Center in Moffett Field, California.

Unique Skills

In 2004 NASA twice flew a demonstration vehicle successfully at hypersonic speeds. Since the demonstration flights, NASA researchers have continued to hone their engineering tools, but budget cuts and other priorities have put plans to build a hypersonic space plane on the back burner.

Nevertheless, "NASA has unique capability and unique engineering skills and facilities that we've developed over 40 or 50 years that could benefit Virgin," Coughlin said.

According to Tai, Virgin Galactic sees that benefit. The collaboration with NASA will allow the venture to tap the agency's engineering prowess to assess the feasibility of a hypersonic passenger service.

"We can't do it ourselves, so we've gone to the experts in the world, which are NASA," Tai said.

Virgin Galactic plans to take customers into space aboard SpaceShipTwo beginning in 2009. The round-trip flights will take off from Mojave. Tickets cost U.S. $200,000.

The two-and-a-half-hour trip, according to Tai, will accustom civilians to space travel much in the same way pilots returning from World War I accustomed civilians to air travel.

World War I pilots went from town to town taking people up for joy rides in their planes as a way to kick-start the airline industry, he said.

Virgin Galactic's spaceflights will also give passengers "an appreciation for the fragility of the Earth and a fantastic view," Tai noted.

"But the long-term goal—going from A to B—is probably where the larger market is," he added.

Check out the article at National Geographic.

I can't wait to book a seat on that flight! Just imagine the photo opportunities!

Top 10 F/X Scenes in Movie History

1. STAR WARS (1977)

Star Wars

Motion-control photography, in which a computer is used to control a long, complex series of camera movements, made possible the spaceship battles in Star Wars. It would have taken too long to film the scenes manually, says Anne Thompson, deputy film editor at The Hollywood Reporter.

2. TRON (1982)

Tron

It wasn't the first film to use computer-generated (CG) graphics (and many effects were hand-drawn) but the sci-fi video-game fantasy flick Tron was the first to use computer imagery to create a 3D world, making it one of the pioneering CGI films. "Effects people said, 'Let's see what the computer can do,'" says Harry Knowles, movie critic at Ain't It Cool News.

3. TERMINATOR 2: JUDGMENT DAY (1991)

Terminator 2 - Judgement Day

"Morphing" was first used in Willow (1988), but in T2 the effect was "jaw-dropping," Knowles says. The liquid-metal robot's humanoid texture, which was layered onto a CG model, looked frighteningly real.

4. CLIFFHANGER (1993)

Cliffhanger

Faux alpinist Sly Stallone was held up by wires that were later digitally removed. The ability to erase wires changed how stunts are done: Now stars and stuntmen can be put in real-world environments as well as in front of green screens.

5. JURASSIC PARK (1993)

Jurassic Park

Although they enjoyed only about 6 minutes of screen time, Jurassic Park's digital dinos were a revelation: They introduced CGI live animals with realistic movements, and believably textured muscles and skin. The photorealisitic digital elements were intercut with animatronic dinosaurs.

6. FORREST GUMP (1994)

Forrest Gump

While most filmmakers in the early '90s used digital effects to create fantasy, the creators of Forrest Gump altered history. Using Kodak's Cineon system, they digitized archival footage, and composited Tom Hanks's character into historical clips.

7. THE PERFECT STORM (2000)

The Perfect Storm

Although much previous work had been done to make CGI water look real, The Perfect Storm's monster wave scene set a new benchmark. "Water is an organic thing that's hard to create in software," says Andy Maltz of the Motion Picture Academy of Arts and Sciences. "To make it look believable was a big thing."

8. LORD OF THE RINGS (2001)

The Lord of the Rings

For the huge battle scenes in the Lord of the Rings trilogy, the filmmakers created Massive, a computer program that generates crowds of artificially intelligent individuals "who make their own decisions based on behavior patterns," Knowles says. This makes for more realistic battles.

9. THE POLAR EXPRESS (2004)

The Polar Express

Director Robert Zemeckis used a large motion-capture stage and up to 200 cameras to gather data from the performance of Tom Hanks and other actors. This data was used to help animators create digital versions of the actors while maintaining their performances.

10. THE DAY AFTER TOMORROW (2004)

The Day After Tomorrow

The creators of the film about worldwide climatic disaster took more than 50,000 photos of New York City and scanned them into a computer, providing "a 3D, photorealistic model of the city," Thompson says. After that, destroying the metropolis with a giant digital wave was a piece of cake.

Check out the article at Popular Mechanics.

That's a pretty good list, but I think they're missing a couple of notable films, such as The Matrix and Back to the Future.

Clean Energy from Garbage?

Longo's Plasma Converter creates clean energy from garbage!

Detailed Schematic of Longo's Plasma Converter

Scene from Back to the Future utilizing a trash converter

Joseph Longo's Plasma Converter turns our most vile and toxic trash into clean energy – and promises to make a relic of the landfill

The entire thing takes up about as much space as a two-car garage, surprisingly compact for a machine that can consume nearly any type of waste—from dirty diapers to chemical weapons—by annihilating toxic materials in a process as old as the universe itself. Called plasma gasification, it works a little like the big bang, only backward (you get nothing from something). Inside a sealed vessel made of stainless steel and filled with a stable gas—either pure nitrogen or, as in this case, ordinary air—a 650-volt current passing between two electrodes rips electrons from the air, converting the gas into plasma. Current flows continuously through this newly formed plasma, creating a field of extremely intense energy very much like lightning. The radiant energy of the plasma arc is so powerful, it disintegrates trash into its constituent elements by tearing apart molecular bonds. The system is capable of breaking down pretty much anything except nuclear waste, the isotopes of which are indestructible. The only by-products are an obsidian-like glass used as a raw material for numerous applications, including bathroom tiles and high-strength asphalt, and a synthesis gas, or “syngas”—a mixture of primarily hydrogen and carbon monoxide that can be converted into a variety of marketable fuels, including ethanol, natural gas and hydrogen.

Perhaps the most amazing part of the process is that it’s self-sustaining. Just like your toaster, Startech’s Plasma Converter draws its power from the electrical grid to get started. The initial voltage is about equal to the zap from a police stun gun. But once the cycle is under way, the 2,200˚F syngas is fed into a cooling system, generating steam that drives turbines to produce electricity. About two thirds of the power is siphoned off to run the converter; the rest can be used on-site for heating or electricity, or sold back to the utility grid. “Even a blackout would not stop the operation of the facility,” Longo says.

It all sounds far too good to be true. But the technology works. Over the past decade, half a dozen companies have been developing plasma technology to turn garbage into energy. “The best renewable energy is the one we complain about the most: municipal solid waste,” says Louis Circeo, the director of plasma research at the Georgia Institute of Technology. “It will prove cheaper to take garbage to a plasma plant than it is to dump it on a landfill.” A Startech machine that costs roughly $250 million could handle 2,000 tons of waste daily, approximately what a city of a million people amasses in that time span. Large municipalities typically haul their trash to landfills, where the operator charges a “tipping fee” to dump the waste. The national average is $35 a ton, although the cost can be more than twice that in the Northeast (where land is scarce, tipping fees are higher). And the tipping fee a city pays doesn’t include the price of trucking the garbage often hundreds of miles to a landfill or the cost of capturing leaky methane—a greenhouse gas—from the decomposing waste. In a city with an average tipping fee, a $250-million converter could pay for itself in about 10 years, and that’s without factoring in the money made from selling the excess electricity and syngas. After that break-even point, it’s pure profit.

Someday very soon, cities might actually make money from garbage.

Check out the article at Popular Science.

A very impressive invention! With this machine, we'll be able to generate clean energy and reduce the amount of waste that we put in the environment. It's a win-win situation!

Equally impressive is the fact that Sci-fi writers thought of this idea 20 years ago for the movie Back to the Future.

Grand Canyon Skywalk?

A Cold Day in the Grand Canyon

Map of the Grand Canyon

Angel's Window - Grand Canyon

Members of a Native American group based in a remote part of Arizona are hoping to entice more tourists by inviting visitors to step off the edge of the Grand Canyon.

The 1,500-member Hualapai tribe announced last week that the Skywalk—a giant, 30-million-dollar steel-and-glass walkway—will open to the public in March 2007.

The Skywalk will jut out 70 feet (21 meters) from the canyon rim, allowing tourists to go for a stroll with nothing between their feet and the Colorado River—4,000 feet (1,220 meters) below—except for four inches (ten centimeters) of glass.

The Hualapai, or "People of the Tall Pines," are working with the Las Vegas, Nevada-based Destination Grand Canyon to market the Skywalk and draw in valuable tourist dollars.

Many other tribes have turned their government-sanctioned right to run casinos into a major revenue source. But the Hualapai's remote location has undermined their efforts to host gambling.

"This is what's going to feed our tribe."

Grand Roll Out

The Skywalk will be accessible through Grand Canyon West, the tribe's once-humble tourist destination. Although Grand Canyon National Park along the south rim sees about four million tourists a year, until recently Grand Canyon West hosted only about 125,000 visitors.

To help bolster their numbers, the tribe agreed to build the Skywalk, which will eventually be joined by a three-story visitors' center, including a restaurant with patio seating along the canyon.

Mark Johnson, of Las Vegas-based MRJ Architects, has been working on the Skywalk for about three years, beginning with a lengthy design phase.

"There really is no building type for this," Johnson said.

He and a team of tribal consultants, engineers, and geologists started with the idea to build a single, straight walkway that would have stuck out from the canyon wall like a diving board.

They moved through several more design concepts before settling on a U-shaped walkway.

Sometime before opening day in March, the behemoth structure will be rolled out at a rate of half an inch (1.3 centimeters) a minute on tracks while concrete weights anchor the back.

When it's in place, the Skywalk will be anchored to giant poles drilled 40 feet (12 meters) into the canyon wall. Only 120 people will be allowed on the walkway at a time.

Johnson says the rock wall, not the walkway's design, is the wild card that could determine the Skywalk's life span.

At that height, the wall is made of 350-million-year-old limestone—porous material that is highly prone to erosion.

Geologists have a simple explanation for the formation of the Grand Canyon: the Colorado River cuts down through the rock, and the canyon's sides fall in.

Periodic rockfalls are an accepted and unpredictable reality. Johnson said there's no way to tell whether the part of the canyon that will support the Skywalk will last a hundred years or a thousand.

Check out the article at National Geographic.

Talk about going out on a limb... I sure hope those architects know what they're doing!

I think it will be really cool to go out on this thing and get a view of the Grand Canyon from directly above... but there's no way I'm going on this thing when it's up to full capacity! I'll just wait 'til the off-season, or right before they close for the day.

Martian Terraforming

Projected Mars Terraforming Stages

Projected Mars Terraforming Stages


The three covers of the Mars Trilogy: Red Mars, Green Mars, Blue Mars

The Sunset on Mars

The Ragged Landscape of Mars

Martian Research Station

Martian Tent City

The interests of the Mars Society—an organization with the overarching goal of colonizing Mars—tend to elicit snickers from non-space fans. Why talk about building homes on Mars when we have problems on Earth like war, bird flu, AIDS and global warming? To the Mars enthusiast, these scourges simply count among the reasons to ditch this rock and head for the Red Planet.

Robert Zubrin, the founder of the Mars Society, likes to point out that Columbus encountered similar resistance from noobs when he pointed across the Atlantic. But Zubrin isn’t a seafarer—he's a scientist, with calculations that say people could create an oxygen atmosphere on Mars in just over 1,000 years. Compare that with other scientists’ predictions of 20,000 or 100,000 years, and he might seem like he's peddling interplanetary snake oil, but there’s no denying that his scheme for “terraforming” is thoroughly conceived.

Click here for an illustrated guide to Zubrin’s six-step plan for inhabiting Mars.

Check out the article at Popular Science.

I like Zubrin's ideas and I'm all for the future efforts to colonize and terraform Mars. In fact, I'd love to visit the red planet one day... I don't know about living there, but at least an extended vacation.

Well, we're definitely headed in the right direction. With NASA's recent announcement of a Permanent Moon Base, we'll have a great place to stage Mars missions from! Hopefully Mars Bases and terraforming will progress quickly from there.

The very idea of terraforming is fascinating! Check out the Terraforming Wiki Page for an interesting read, cool pics and other links.

If this is a subject that interests you, I highly recommend Kim Stanley Robinson's Mars Trilogy - consisting of Red Mars, Green Mars, and Blue Mars. In this awesome work of science fiction, Robinson delves into the technological, social and political aspects in a realistic future of Martian colonization and terraforming. You'll find no light-sabres or warp drives in these books... just down-to-earth, well-written sci-fi!!!

Hypersonic Cruise Missile?

THE MISSION:
Attack anywhere in the world in less than an hour.

But is America's New Global Strike Weapon
a critical new method for hitting elusive targets,
or a good way to set off a nuclear war?
X-51 Hypersonic Cruise Missile

Ohio Class Missile Submarines will fire the X-51 Cruise Missile

The B-52 Stratofortress will fire the X-51 Cruise Missile

X-51 Hypersonic Cruise Missile deployment strategy

X-51 Hypersonic Cruise Missile deployment strategy

A tip sets the plan in motion — a whispered warning of a North Korean nuclear launch, or of a shipment of biotoxins bound for a Hezbollah stronghold in Lebanon. Word races through the American intelligence network until it reaches U.S. Strategic Command headquarters, the Pentagon and, eventually, the White House. In the Pacific, a nuclear-powered Ohio class submarine surfaces, ready for the president's command to launch.

When the order comes, the sub shoots a 65-ton Trident II ballistic missile into the sky. Within 2 minutes, the missile is traveling at more than 20,000 ft. per second. Up and over the oceans and out of the atmosphere it soars for thousands of miles. At the top of its parabola, hanging in space, the Trident's four warheads separate and begin their screaming descent down toward the planet. Traveling as fast as 13,000 mph, the warheads are filled with scored tungsten rods with twice the strength of steel. Just above the target, the warheads detonate, showering the area with thousands of rods-each one up to 12 times as destructive as a .50-caliber bullet. Anything within 3000 sq. ft. of this whirling, metallic storm is obliterated.

If Pentagon strategists get their way, there will be no place on the planet to hide from such an assault. The plan is part of a program — in slow development since the 1990s, and now quickly coalescing in military circles — called Prompt Global Strike. It will begin with modified Tridents. But eventually, Prompt Global Strike could encompass new generations of aircraft and armaments five times faster than anything in the current American arsenal. One candidate: the X-51 hypersonic cruise missile, which is designed to hit Mach 5 — roughly 3600 mph. The goal, according to the U.S. Strategic Command's deputy commander Lt. Gen. C. Robert Kehler, is "to strike virtually anywhere on the face of the Earth within 60 minutes."

The question is whether such an attack can be deployed without triggering World War III: Those tungsten-armed Tridents look, and fly, exactly like the deadliest weapons in the American nuclear arsenal.

Check out the article at Popular Mechanics.

I think it's very important for America to have far-reaching non-nuclear weapons technology. Currently, our best weapons (nukes) are total overkill... especially in the War on Terror. I'm all for this new technology... we just have to figure out this little problem of potentially setting off WWIII.

Remote Controlled Warfare!

Predator B - MQ-9 Reaper hunter/killer UAV

Predator B - MQ-9 Reaper hunter/killer UAV

Military commanders use tactics and strategy in combat to inflict as much damage on the enemy while trying to risk as few personnel and resources as possible. This principle was at the heart of the development of the RQ-1 and MQ-1 Predator Unmanned Aerial Vehicle.

These high-tech aircraft, controlled by a crew miles away from the dangers of combat, are capable of reconnaissance, combat and support roles in the hairiest of battles. In a worst-case scenario, if a Predator is lost in battle, military personal can simply "crack another one out of the box" and have it up in the air shortly -- and that's without the trauma of casualties or prisoners normally associated with an aircraft going down.

In May 1998 General Atomics was awarded a Block 1 Upgrade contract to expand the capabilities of the Predator system. System upgrades include development of an improved Relief-On-Station (ROS) system which allows continuous coverage over areas of interest without any loss of time on station, secure air traffic control voice relay, Ku-band satellite tuning and implementation of an Air Force Mission Support System (AFMSS).

The upgrade also covers a more powerful turbocharged engine and wing de-icing systems to enable year-round operations. The upgraded Predator, the MQ-9 Reaper Hunter/Killer, has been operational in the Balkans since April 2001. In March 2005, the USAF awarded a further contract for the System Design & Development (SDD) of MQ-9. 15 MQ-9 have been ordered and eight delivered to the USAF. A decision on full-rate production is expected in 2009.

The Predator B has an operational ceiling of 50,000ft and maximum internal payload of 800lb and external payload over 3,000lb. Predator B (MQ-9 Reaper hunter/killer) has been flight tested with Hellfire II anti-armour missiles and can carry up to 14 missiles. The MQ-9 will also be able to deploy the GBU-12 and EGBU-12 bombs and 500lb GBU-38 JDAM (Joint Direct Attack Munition). MQ-9 flight trials have also taken place with the General Atomics Lynx SAR (Synthetic Aperture Radar) payload. Lynx also features ground moving target indicator technology. The Predator is to be flight tested with a L-3 Communications Tactical Common Datalink (TCDL).

The UAV ground control station is built into a single 30ft trailer, containing pilot and payload operator consoles, three Boeing data exploitation and mission planning consoles and two synthetic aperture radar workstations together with satellite and line-of-sight ground data terminals. The mission can be controlled through line-of-site data links or through Ku-band satellite links to produce continuous video.

The USAF has also ordered two versions of Predator B with turbofan jet engines, to be known as Predator C. First flight of the Predator C is expected in early 2007.

Check out the article at HowStuffWorks.com.

Check out the article at Airforce Technology.

I bet it would be really cool to fly one of these! It couldn't be any tougher than the latest Microsoft Flight Simulator game, right? I'm waiting for a civilian model that can be flown from your home computer!

If you think this is cool... just wait until you see the Predator's little brother, the Dominator (which is smaller, more expendable, and travels in groups of 100) and the concept for the new UCAV!

Space Slingshot?

Forget rockets!
All you need to launch a satellite is
a sled and a giant magnetic slingshot

Concept Art of the Magnetic Space Slingshot

Magnetic Space Slingshot Schematic

Astronauts are trained to withstand as much as nine times the force of gravity. (Three Gs, by comparison, could make the average guy pass out.) But even the toughest among them fall out of the running when it comes to a launch concept from a small civilian company in Goleta, California. To survive the ride on Launchpoint Technologies’s invention, the payload has to be able to survive a brain-splattering 10,000 Gs.

The design calls for a high-speed accelerator that whips a projectile as heavy as 220 pounds around a circular 1.5-mile-radius vacuum tunnel. Powerful electromagnetic motors inside the tunnel will accelerate the unit, strapped to a magnetic sled, in circles until it reaches a velocity of six miles per second and then will eject the projectile from a launch ramp into space.

The system is still just an idea on paper, but the U.S. Air Force has awarded Launchpoint a two-year, $500,000 grant to prove it can work. Project leader Jim Fiske, an expert in magnetic levitation, believes that the magnetic forces would counteract the pulverizing G-forces generated by radial acceleration and prevent the sled from touching the tunnel wall.

As for the system’s cost, its low power requirements would allow spy micro-satellites to be slung into orbit for $50,000, a small fraction of the current $5-million launch cost. That explains the Air Force’s interest, but the system could also be a boon for space exploration. An inexpensive magnet-propelled pipeline could toss construction materials, food and other basic resources into orbit to supply tomorrow’s space colonies. “You could send a block of aluminum, water or even frozen mashed potatoes,” Fiske suggests—anything durable enough to handle the stress.

Fiske says a demonstration device could be ready in four years and will probably be located on a dry lake bed at the Department of Energy’s Nevada Test Site. But future launch rings, he adds, could sit near mountain ranges or even float on the ocean.

How it Works

The Sled: The projectile is encased in a protective polycarbonate sabot and attached to a magnetic sled with a Kevlar sheet. When the sled reaches launch speed, a laser slices through the sheet, freeing the projectile to enter the launch ramp.

The Launch: The projectile contains a small rocket engine and avionics that enable it to steer itself into orbit once it escapes Earth’s atmosphere.

The Track: Magnetic motors above and below the vacuum tube create a magnetic field that accelerates the sled to six miles per second.

Check out the article at Popular Science.

What an interesting design concept! If this can be perfected, imagine the amusement park rides of the future!

Not to mention, the amount of money NASA and the Air Force could save and apply to the Moon outpost and Mars missions. I hope they can make it work!

Crater Rim Moonbase?

Craters at the Moon's South Pole

The Orion Moon Lander Module

Potential Initial Moon Base Design

NASA is on a flight path to replant astronauts on the Moon, looking to sustain a human presence on that cratered, airless orb on a "go-as-the-nation-can-afford-to-pay" basis. That approach is seen as letting people step back onto the lunar surface no later than 2020.

Space engineers have honed in on one possible site for a lunar outpost: the Moon's south pole.

It's a tactical setting on the rim of Shackleton Crater, a feature some 12 miles (19 kilometers) in diameter.

There's real estate here that basks in near-perpetual sunlight. Also, it's a region that is a doorway into the depths of always dark, Sun-deprived, territory.

What's possibly lurking there in that super-cold darkness is water ice — portrayed by some researchers as the gold standard for future exploration on and from the Moon. Yet there is considerable debate about this resource. If there, such a raw storehouse might be processed into usable oxygen and hydrogen.

Ample evidence

According to NASA Moon outpost thinkers, there are five key reasons for building up an encampment near a lunar pole:

Polar sites have plenty of sunlight, which lessens concerns about energy storage. It would be possible to operate a polar outpost on solar power. While not highlighting it as such, NASA's go-solar tactic also doubles as a non-nuclear, perhaps more politically correct approach.

The environment at the poles of the Moon is relatively benign, making it easier to design a habitat. Temperatures at the poles vary no more than about 50 degrees Celsius all year round, while temperatures at the equator can vary 250 degrees Celsius from day to night.

At the Moon's south pole there is "ample evidence," NASA planners point out, of enhanced hydrogen — an important natural resource for future development for energy generation, propellant production and other potential uses.

The poles can teach robotic and human explorers volumes about the Moon. This landscape is among the most complex of regions, yet very little is known about them.

To land equipment and scientific payloads near the lunar south pole, specifically, as opposed to another location, will require less propellant and could be more cost effective.

Check out the article at Fox News.

This is getting more and more interesting! I can't wait until this comes to fruition, then I can talk to my travel agent about lunar tourism!

Underwater Hotel

Pacific Ocean Atoll

View from Above

Top Notch Underwater Accomodations

Spectacular Undersea View

Bruce Jones has spent much of his career designing underwater toys for the rich and famous. The 50-year-old president of U.S. Submarines is best known for building ultraluxe custom subs, $80-million vessels that feature private staterooms, paneled interiors made from exotic hardwoods, plush carpeting, and enough onboard oxygen to keep you and 10 friends breathing easy for three weeks of cruising at depths of nearly 1,000 feet. Now Jones is redirecting his expertise in undersea opulence toward the hotel industry. His plan: to open the Poseidon Mystery Island, the world’s first major resort at the bottom of the ocean, by September 2008.

The hotel, which will sit in about 40 feet of water, will boast individual suites, as well as a library, a wedding chapel and a restaurant. In addition to scuba diving, the guests will be able to cruise around the lagoon in either a 16-person submarine capable of 300-foot-depths, or learn to pilot a three-person Triton sub, which can reach 1,000 feet.

Jones designed Poseidon to provide guests—scuba aficionados and landlubbers alike—with an all-inclusive vacation package: fine dining, stunning views of the surrounding lush coral habitat, and the opportunity to dive directly from the hotel’s airlock, a hatch that lets divers out but keeps the sea from flooding into the hotel. Once the resort opens, visitors staying in one of the 550-square-foot guest rooms will enjoy a 270-degree view of the vibrant coral reef and tropical fish, visible through floor-to-ceiling windows and illuminated by external flood lighting. Guests will access the hotel through two elevators. Because the interior pressure will be held at one atmosphere (the same pressure as onshore), they won’t have to worry about getting decompression sickness. A Frisbee-shaped module at one end of the resort will house a kitchen, reception lounge and 3,000-square-foot rotating restaurant and bar. A second saucer will enclose a library, a conference room, a wedding chapel, a spa and the largest underwater accommodation in the world, the 1,200-square-foot “Nautilus” suite priced at $15,000 a night. To ensure that guests always have a crystal-clear view of the teeming marine life, Poseidon will have an automatic window-cleaning system (barnacles, algae and other marine creatures cling to just about anything in the sea). High-powered water jets will glide along tracks mounted to the sides of the resort, spraying the windows with high-pressure seawater, filtered so as not to coat the acrylic with barnacle larvae or other critters—a mechanism modeled after the cleaning jets in an automated car wash.

If the windows of a guest module become damaged, or if the room requires other repairs, maintenance workers can detach it from the main body of the resort and bring it to the surface. To loosen the joint that connects each suite to Poseidon’s “spine,” workers will close the watertight doors separating the guest module from the spine and then pump the joint full of seawater. As the hydrostatic pressure increases inside the coupling, it will force the suite loose so that an overhead crane can hoist it out of the water.

Like so many other ambitious hotel-resort plans, Poseidon must overcome unenviable logistical hurdles before the first guest walks through the door. Other promising underwater projects have ground to a halt because of budget overruns and legal wrangling. Even funding and lagoon space isn’t a surefire guarantee that Poseidon will ever be completed, although Jones’s decision to pre-fab the hotel, rather than risk the vagaries of underwater construction, tips the odds in his favor. Finally, some industry analysts are skeptical that the pool of potential guests is large enough to keep the hotel afloat. But Jones is confident that he will be taking guest reservations for Poseidon—and that guests will pony up the $15,000-per-person, per-week reservation fee—for a long time to come.

Check out the article and slideshow or the photo gallery at Popular Science.

What a cool idea! Not only will it be great for tourism, but in an overpopulated future this technology may become a lifestyle for some groups of people.

I'll just settle for the underwater vacation, and keep my house on solid ground.

How We'll Get Back to the Moon

The Moon

Moonrise

Ares V Cargo Ship

Ares I Crew Ship

Moonbase

NASA has announced plans to establish a permanently-occupied lunar base with manned missions starting in 2020, a key step in further human exploration of the solar system.

The project, which would send humans back to the lunar surface for the first time since 1972, is a long-term joint effort of 14 of the world's space agencies, the National Aeronautics and Space Administration said Monday.

According to the current plan, which NASA described as a "blueprint for a return to the moon," robots would travel to the lunar surface ahead of manned missions to study the best landing sites and determine what natural resources would be available.

Then, starting in 2020, four-person crews bringing lunar exploration vehicles would be dispatched on a series of week-long missions to build living quarters equipped with their own power units.

Once permanent housing is established the program envisions lunar missions lasting 180 days.

NASA plans to set up a solar-powered base on one of the moon's poles that, once construction is completed, could serve as a forward base for manned missions to Mars.

"With such an outpost, NASA can learn to use the moon's natural resources to live off the land, make preparations for a journey to Mars, conduct a wide range of scientific investigations and encourage international participation," NASA said.

In 2004, US President George W. Bush had raised the idea of sending a manned exploratory mission to the red planet.

To help set out the goals of the lunar station, NASA consulted more than 1,000 experts. NASA officials talked to members of 13 other space agencies — including those of China, India, Russia and Ukraine — as well as experts from academic, public and private groups, and business interests.

This strategy will be "making optimum use of globally available knowledge and resources to help energize a coordinated effort that will propel us into this new age of discovery and exploration," said NASA Deputy Administrator Shana Dale.

NASA is developing a new crew capsule, the Orion, and new rocket engines, the Ares, for the mission. Test flights for the new rockets are scheduled for within two and a half years, and the Orion capsule is scheduled to be first flown around 2012.

In the meantime the space agency plans using the current space shuttle fleet until it is retired in 2010, with a focus on completing the building of the International Space Station.

NASA, Russia and the European Space Agency are currently constructing the ISS, in orbit around the Earth, which could itself be a springboard and operations base for the moon program.

Check out the article at Discovery News.

I really am looking forward to this! Just imagine how much more we will learn about the moon and surviving in space! It's going to be good practice for Mars.

Hubble Space Telescope to get upgrade!

Hubble Space Telescope

Cats Eye Nebula - photo taken by Hubble Space Telescope

The terrific thing about NASA chief Michael Griffin’s decision to launch a Hubble servicing mission—the telescope’s fifth since 1990—isn’t simply that the spacecraft will be able to limp along for another four years. After astronauts visit Hubble on this latest mission (set to launch no earlier than May 2008), the telescope will be more powerful than it has ever been, thanks to some incredible new instruments being tested now.

The first is a replacement for Hubble’s main camera, the 13-year-old Wide Field Planetary Camera 2. The new camera, cleverly named the Wide Field Camera 3, will do everything the old camera did, but better. It’s like keeping all the lenses from your old film camera but upgrading to a professional-model digital SLR body.

I was lucky enough to be at the NASA Goddard Space Flight Center yesterday right after the announcement was made, and I spoke with James Green, principal investigator for the Cosmic Origins Spectrograph project, the other major upgrade scheduled for the servicing mission. The COS had just been loaded for testing into a sort of three-story-tall, 50-foot-wide Thermos that’s designed to replicate the vacuum and temperature extremes of space. It will pummel the COS for the next two months.

Above the din of the vacuum pumps, Green explained that the COS will be the first instrument that will allow scientists to track the 95 percent of normal matter in the universe that doesn’t glow—the interstellar gas clouds wafting between stars and galaxies. It will look at distant quasars and trace how these clouds absorb the quasars’ light. In this way, scientists can tell what elements and molecules the clouds are made of, and hence can map the hidden structure of the universe.

If all goes well, the servicing mission should keep the new, improved Hubble working until 2013, when its successor, the James Webb Space Telescope, is set to launch.

Voyaging to Interstellar Space

NASA Voyager Mission

The Heliosphere

Voyager 1 logged yet another milestone in space history August 17 when it crossed an invisible boundary that marks 100 astronomical units (AU) from the Sun -- about 15 billion kilometers (9.3 billion miles) out there -- farther away than any human-made object has ever gone in space. It's headed now for interstellar space. Voyager 2, at 80 AU, is about six years behind.

Nearly 30 years after the twin Voyager spacecraft took off from Cape Canaveral, the mission has become a legend in its own time, rewriting the planetary science books, and introducing us to our own diverse neighborhood. The twins, meanwhile, have become the poster children of space exploration, still communicating after all these years and sending data home regularly via the Deep Space Network.

“One of our objectives was to explore interstellar space, and following the successful Saturn flyby in 1981, the mission was renamed the Voyager Uranus Interstellar Mission," said Voyager Chief Scientist Ed Stone, professor of physics and director of the Space Radiation Laboratory at the California Institute of Technology (Caltech), and a former director of the Jet Propulsion Laboratory (JPL), where the mission was designed and is being managed. "This was a boldly optimistic goal because we knew neither how long it would take to reach interstellar space nor how long the spacecraft would continue operating beyond their original 4-year mission to Saturn which is only 10 AU from the Sun. It is indeed remarkable that the Voyager spacecraft have already operated 7 times longer and 10 times further from the Sun than originally planned," he said.

"With some luck, the two will reach interstellar space while they still have electrical power," continued Stone, who has been the project scientist on the mission since 1972, overseeing the efforts of 11 teams of scientists in their studies of Jupiter, Saturn, Uranus, and Neptune. "Whether they reach interstellar space or not under power, they will be -- and [Isaac] Newton tells us this -- humankind's first interstellar probes, the first objects launched from Earth to reach interstellar space. Crossing into interstellar space will be a major milestone in our journey from Earth into the Milky Way."

Check out the article at The Planetary Society.

Together, Voyager 1 and Voyager 2 -- twin probes launched on September 5, 1977 and August 20, 1977 -- represent the most successful planetary exploration mission of all time. In their flybys of all the outer planets, and dozens of other planetary bodies, the Voyagers set the benchmark in planetary exploration on an undertaking that has come to be deemed as one of NASA’s greatest triumphs.

The two 1-ton spacecraft returned more knowledge-changing data than any mission before or since: stunning photographs that consistently revealed our solar system to be much more diverse, complex, and beautiful than anyone ever imagined, and a veritable bounty of scientific information to go along with them.

Even now, both Voyager spacecraft are still communicating with Earth. Many of their instruments are still functioning, as the two spacecraft head in different directions out of the solar system on their "Interstellar Mission." Voyager 1 has now passed the termination shock, where the solar wind abruptly slows down as it pushes against the interstellar medium.

Asteroid Defense?

Asteroid!

Deep Impact

Experts say there are an estimated 1,100 known objects that are 1 kilometer (about a half-mile) or wider across — large enough to not only take out a sizable European country but threaten the entire world.

"The goal is to discover these killer asteroids before they discover us," said Nick Kaiser of the University of Hawaii's Institute for Astronomy, whose Pan-STARRS program will train four powerful digital cameras on the heavens to watch for would-be intruders.

NASA's Spaceguard Survey, which already has identified 800 of the larger objects and has 103 on an impact risk watchlist, wants to find 90 percent by the end of 2008.

The U.S. Congress has asked the space agency for a plan to comb the cosmos for faint objects as small as 140 meters (153 yards) across and log their position, speed and course by 2020.

Astronomers will have their work cut out for them: Experts say there are about 100,000 such objects hidden among the haze of stars, and as many as 1 million half that size.

One known as the Tunguska object slammed into remote central Siberia in 1908, unleashing energy equivalent to a 15-megaton nuclear bomb and wiped out 60 million trees over an 830-square-mile area. Had it hit a populated area, the loss of life would have been staggering.

Giovanni Valsecchi of Italy's National Institute of Astrophysics said the ultimate aim is a permanent warning system like those that now monitor the Pacific for tsunamis and keep tabs on volcanoes and earthquake zones.

The idea: Give the world enough lead time to come up with a workable response to a confirmed threat, such as sending up a rocket to deflect an Earth-bound object or a spacecraft to nudge it into a harmless orbit.

"Right now, unfortunately, there are no 'asteroid busters' or hotlines. Who ya gonna call?" said Andrea Milani Comparetti, a professor of mathematics at the University of Pisa.

The IAU offered some reassurance Thursday about 99942 Apophis, a smallish asteroid that will come within just 18,000 miles of Earth when it whizzes by in 2029. That's closer than many commercial satellites, and 220,000 miles nearer than the moon.

Last year, scientists were concerned Apophis could come even closer in another fly-by in 2036, with a 1-in-5,500 chance of striking Earth with enough energy to wipe out New York City and its suburbs.

Check out the article at Fox News.

You have to wonder how many asteroids are out there heading this way. It might be a good idea to form some kind of contingency plan to avoid potential impacts.

The current cutting edge of fighter design combines previous emphasis on versatility with new developments such as thrust vectoring, composite materials, supercruise, and stealth technology. To date, none of these aircraft have been used in combat. Current developments include reducing the radar visibility of fighters—techniques known as stealth—as well as increased range at supersonic speeds (supercruise) and better maneuverability.

Of these, only the American F-22 Raptor, put into production in 2004 are operational, and it is often regarded as the first of a new generation of fighters, termed the fifth generation. (Although the European Eurofighter Typhoon is often considered a direct rival to the F-22 Raptor with a similar performance). The in-development F-35 Lightning II (formerly Joint Strike Fighter) has also been designed for stealth, and the F-22 has influenced the continued development of the 4th generation designs, and the shape of design work for other countries' long-term fighter development projects (for instance, the rumoured Chinese Shenyang J-XX project, Indian Medium Combat Aircraft, and the Russian PAK FA).

Space Elevator

Space Elevator

Space Elevator Diagram

Space Elevator Concept

Space Elevator Concept

Admittedly, at least for now, the idea of a beanstalk-like space elevator connecting Earth and space is a stretch.

But next month’s X Prize Cup will host the Space Elevator Games, an unprecedented challenge for today’s engineers looking at ways to alter the future of access to space.

Teams from around the country will gather October 20-21 in Las Cruces, New Mexico to compete for $400,000 in prize money as part of NASA’s Centennial Challenges—the space agency’s program of prize contests to stimulate innovation and competition in solar system exploration.

No matter how you look at it—from the top down or bottom up—building a full-scale space elevator is an uphill battle. But at least physics is in your favor.

The concept is a system utilizing an ultra-strong ribbon that extends from the surface of the Earth to a point beyond geosynchronous orbit. The ribbon is held in place by a counterweight in orbit. As the Earth rotates, the ribbon is held taut. Vehicles would climb the ribbon powered by a beam of energy projected from the surface of the Earth. [See video animation here.]

Visionaries like science fact/fiction writer, Sir Arthur C. Clarke, are space elevator advocates.

Still, wordsmithing the technology is a far cry from hammering it out for real, and there are those who believe the innovations and breakthroughs needed, like nanotubes, might not work.

Check out the article at Space.com.

What an awesome concept! This would be a major investment, but would save so much fuel and energy in the long run that it would be a bargain for whoever builds it. We just need to make sure we keep such a major project out of any one entity's possession... it needs to be a world collective project.

On the other hand, just read Red Mars to see what kind of catastrophe the sabotage of a Space Elevator would be.

A New Look at an Old Face

Valles Marineris - The Grand Canyon of Mars

Face on Mars - 1976 Viking Orbiter 1 Photo

New Look at an Old Face

The famous "Face on Mars" has gotten another close-up.

The European Space Agency has released new, highly detailed images of the controversial, face-like formation first captured by a Viking orbiter at Mars’ Cydonia region in 1976.

The Face may be a popular target for orbiters – NASA’s Mars Global Surveyor snapped images in 1998 and 2001 – but it’s not an easy one.

The site, located at 41 degrees north Martian latitude, is often obscured by atmospheric dust and haze. Still, after several attempts, the High Resolution Stereo Camera on board ESA’s Mars Express captured a series of images with a ground resolution of approximately 13.7 meters per pixel.

"These images of the Cydonia region on Mars are truly spectacular," said Agustin Chicarro, ESA Mars Express Project Scientist. "They not only provide a completely fresh and detailed view of an area famous to fans of space myths worldwide, but also provide an impressive close-up over an area of great interest for planetary geologists."

Chicarro and his team say the high-resolution images further confirm what NASA scientists have been saying for years: It’s not a face, but a raised, eroded surface.

NASA’s chief scientist for Mars exploration, Jim Garvin, describes the formation as the equivalent of a butte or mesa, landforms common around the American West. Such formations are common in Mars’ Cydonia region, which is located between the planet’s southern highlands and northern plains.

But then, some may never be convinced.

Since the spooky, face-like structure was first photographed by NASA’s Viking 1 Orbiter 30 years ago, the site has been the subject of breathless speculation.

In movies, books and on the Web, some have argued this is a massive sculpture built by intelligent life and that surrounding conical-like structures are pyramids, or remnants of a great city, built by a complex civilization.

Check out the article at Discovery News.

Natural shapes can take on many forms when viewed with the human eye... ever looked for shapes in clouds?

Upgraded Space Station May Rival Venus in Night Sky

The biggest and brightest man-made object orbiting Earth just got bigger and brighterInternational Space Station - 2006

International Space Station - 2005

Space Shuttle Atlantis

Astronauts on board the international space station unfurled a new pair of solar-energy panels that sprout out of the end of a new 17.5-ton truss section, which was brought up by the space shuttle Atlantis.

They are the largest solar panels ever taken to space; fully unfolded, they reach a length of 240 feet (73 meters).

They are designed to double the ISS' capability to generate power from sunlight when they go online during a future shuttle mission.

Like other satellites, the ISS shines by virtue of sunlight reflected off of its metallic skin. The station orbits approximately 213 miles (341 kilometers) above Earth.

How bright?

Before the ISS spread its new pair of gold wings, it was already the brightest of all space vehicles, at times appearing to shine with a brilliance equal to the planet Jupiter.

Now skywatchers should notice the orbiting outpost glowing with an even greater luster.

Nobody knows exactly how much brighter it will be, but there's a good chance that it could be brighter than magnitude -3, approaching the glow of Venus, the brightest planet.

On this astronomers' scale, smaller numbers denote brighter objects, and negative numbers are reserved for the handful of the very brightest.

The ISS will likely get even brighter. The solar panels are only the second of four planned arrays that will be deployed between now and when the shuttle fleet retires in the year 2010.

When to look

Skywatchers across much of North America will have opportunities to see the ISS in the coming weeks.

To the unaided eye, it appears as a large "star" with a yellowish-white tint that moves with a steady speed across the sky.

Beginning late next week and running through the first two weeks of October, early risers will be able to look for the station in the dawn twilight if skies are clear.

Starting in mid-October, it will make passes during convenient evening hours, soon after sundown.

To find out if the international space station will pass over your hometown, go to NASA's tracking page or the Heavens Above web site.

Amateurs with large telescopes and some knowledge of astrophotography have in the past had success photographing the space station.

Check out the article at Fox News.

I'm hoping to catch a good photo of it this month!

Terrorism vs. Technology

Raghead Mujahideen Sketch
Airport Luggage X-Ray
Toxin sniffers, missile jammers, dirty-bomb detectors:
Will a new security arsenal make us safer?

Five years after terrorists chillingly exposed our home-front vulnerabilities to unconventional warfare, are we safer? Ask Maureen McCarthy, director of science and technology transition at the Department of Homeland Security, and she answers in a word: “Absolutely.”

Pause. Clarification: “They can still game us, but figuring out how to get past our defenses now is harder to do.”

In the race to prevent future 9/11-style attacks—or worse—Washington has marshaled the U.S. science establishment on a scale not seen since Sputnik. Federal investment in homeland-defense research has swallowed nearly $4 billion since 2003, and that’s a mere drop of total security spending. (DHS’s budget this year alone is $40 billion.) More important, McCarthy suggests, is that the accelerated spending has brought together formerly disparate disciplines: Software engineers, epidemiologists and biologists have teamed up to produce technologies that protect air and food against bioterrorism. Nuclear physicists and bioforensics specialists now cooperate with the best brains in behavioral science to devise ways to reduce the threat of nuclear smuggling and suicide bombers.

Yet some experts argue that much of the big spending provides only an illusory sense of security. “A lot of it is security theater—technology designed to make you feel better,” says Bruce Schneier, author of Beyond Fear: Thinking Sensibly about Security in an Uncertain World. He points to high-tech protection poured into landmarks, from the White House to local city halls, that he claims diverts terrorist attention to “softer” targets like subways and stadiums. But the government seems to have taken the point. Its ever-expanding homeland-security measures cover not just big targets but the nation’s broader vulnerabilities as well.

Check out the article at Popular Science.

For a look at the technologies that will soon safeguard your travel plans, launch the photo gallery.

There will always be "soft targets" for Islamic militant extremists, we just need to make sure they don't hit a vital area. One major vital area that we are extremely vulnerable in is our shipping ports. There's a hella lot of cargo coming in through our major port cities, such as New Orleans, every day.

Not many people are talking about shipping ports because of the fact that recent targets were passenger aircraft on 9-11 and very recently in England. I would think it important to correct such a vulnerability BEFORE it is exploited... wasn't 9-11 a big enough wake-up call? No, it was only a wake-up call for the airline industry.

It's like plugging a leaky dam one hole at a time... sooner or later we're going to run out of fingers.

Smart Gun?

Smart Gun

Armed with $2 million in federal grants, researchers at the New Jersey Institute of Technology (NJIT) are close to perfecting the first commercially viable "smart gun." The prototype pistol, unveiled last month, is designed to recognize specific people's grips. When seized by an unauthorized hand—say, that of a child or a criminal—the gun locks its shooting mechanism.

Gun-safety advocates hail the device as a way to significantly reduce the estimated 29,000 firearm deaths in the U.S. each year, although some gun-rights advocates worry that the technology could prove more error-prone than traditional guns. Sebastian says the NJIT prototype currently has a failure rate of 1 in 100 trigger pulls, but his team aims to improve that rate to 1 in 10,000—the Pentagon's standard for military weapons—by increasing the number of grip sensors from 32 to "hundreds" and further refining the pattern-recognition software. If all goes well, Sebastian expects a commercial version by 2008.

Check out the article at Popular Science.

I like the way this is going, but they're not there yet. Look for the gun rights opponents to call for legislation to make this mandatory in all weapons.

I really only have one concern... Let's say you are in a gunfight with an intruder in your home. You are shot in the shoulder, but are still alive and aware enough to switch hands and defend yourself before the intruder comes to finish you off. But, you are no longer gripping the weapon as it was programmed to be gripped. Too bad, you're SOL!

NASA's CloudSat Mission

Revealing the inner secrets of clouds!
NASA CloudSat

Rainbow Clouds

Noctilucent Clouds

Cumulous Clouds
Cumulous Storm Clouds - photo by Renegade

In early 2006, NASA launched the CloudSat and the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) spacecraft to study the role that clouds and aerosols play in regulating Earth's weather, climate and air quality.

Scientists are improving their understanding of Earth's climate system, but many questions remain. Weather and climate models, the prediction tools scientists use to study the Earth system, are complicated, and the information scientists use to build the models is incomplete. CloudSat and CALIPSO will collect information about the vertical structure of clouds and aerosols unavailable from other Earth observing satellites. Their data will improve our models and provide a better understanding of the human impact on the atmosphere. Policy makers and business leaders will make more informed long-term environmental decisions about public health, the economy and better day-to-day weather predictions as a result of these missions.

For the first time from Earth orbit, CloudSat and CALIPSO will:
- Provide statistics on the vertical structure of clouds around the globe (both missions)
- Provide statistics on the geographic and vertical distribution of aerosols around the globe (CALIPSO)
- Provide estimates of the percentage of Earth's clouds that produce rain (CloudSat)
- Detect subvisible clouds in the upper troposphere and Polar Stratospheric Clouds (CALIPSO)
- Provide vertically-resolved estimates of how much water and ice are in Earth's clouds (CloudSat)
- Detect snowfall from space (CloudSat)
- Estimate how efficiently the atmosphere produces rain from condensates (CloudSat)
- Provide an indirect estimate of how much clouds and aerosols contribute to atmospheric warming (both missions)

Check out the article at NASA's Homepage.

Some excellent images are coming back from these satellites! Just imagine how much extraordinary data they will provide!

Tank + Motorcycle =

Hyanide
Hyanide
Deep mud, sand and snow are no match for this go-anywhere mutated motorbike!

You may not have room in your garage (or budget) for a dirt bike and a snowmobile and a four-wheeler. But what if one vehicle could take the place of all three? That’s the idea behind the Hyanide, a wild concept vehicle created by German designers Oliver Keller and Tillman Schlootz for the 2006 Michelin Challenge Design. This year’s competition showcased vehicles made especially for California’s diverse and often rugged topography.

Named for its supposed resemblance to a crouching hyena, the Hyanide is designed to run on a flexible rubber tread that spans the machine’s entire underside. So if any part of the bottom is touching the ground, the Hyanide should be able to move, no matter how deep the quagmire, no matter how rough the terrain. The tank-like tread consists of 77 identical segments—each made from hard plastic covered with tire rubber —held together by Kevlar rope. Each segment flexes independently, making the tread significantly more limber than if its components were rigid. Not only does this setup help with traction, but it would allow the tank-cum-motorcycle to corner like no other vehicle!

Check out the article at Popular Science.

How could that replace a 4-wheeler? I don't see any place to put the deer!

Graham Flint is the sort of man who uses the structural bracing of a nuclear reactor's safety door as a camera stand. The bracing secures his camera casing to the inside of his minivan and is indicative of the precision and focus with which he approaches all aspects of his life, none more so than his current and most ambitious project: a 1,000-shot survey of America at the dawn of the 21st century, his Portrait of America, taken with the camera he designed and built, the highest-resolution landscape camera ever created.

Flint knows that he may already have devised something more profound than a crisper image. He tells the story of how the 19th-century photographer Eadweard Muybridge—who famously showed that all four of a galloping horse's hooves are off the ground at the same time—used his camera as a scientist would. "He's somebody who used photography to create an image that was both startling and different and gave people an understanding that they didn't have before," Flint says. "We're trying to take images that people have photographed thousands of times and give people a whole new perspective of those scenes." Despite Flint's own protestations to the contrary, perhaps the 21st century has found Muybridge's corollary: the scientist who uses his camera as an artist.

Mining the Moon

Mining the Moon

Crashing Moon screenshot from The Time Machine
screenshot from The Time Machine

Before NASA sends astronauts to live on the moon in 2020, per presidential mandate, the agency must first figure out what resources the lunar neighborhood has to offer. Are there stores of ice that could be melted and processed to provide oxygen to breathe and hydrogen for rocket fuel? Or is the potential fuel locked up inside rocks? To find out, NASA has a simple yet ingenious plan, set to launch in 2008: Slam two chunks of steel into a crater near the moon’s southern pole and study what flies out. Of top interest is hydrogen, discovered beneath the soil during previous missions. The key here, says NASA investigator Anthony Colaprete, is that scientists will finally learn how the hydrogen is stored—in ice, minerals or as free protons in the lunar soil. This information, he explains, “will tell us which way we need to go in terms of the technology for extracting it.”

Launch this slideshow to see how LCROSS will bring NASA one step closer to its lunar home away from home.

Check out the article and video at Popular Science.

I wonder if they've seen The Time Machine! In the movie, humans miscalculated the impact of demolitions during the colonization of the moon... throwing the orbit off and sending it crashing down on us, nearly rendering mankind extinct.

I hope NASA knows what they're doing!

Medusa Multicaliber Revolver

Medusa Multicaliber Revolver
How the Medusa works

The shooter in the bay next to mine watches skeptically as I load the conventional-looking revolver with an unusual array of ammunition: a .380 ACP, two 9mm Lugers, a .38 Special Plus-P and two .357 Magnums. He maintains a discreet distance as, with my right index finger outside the trigger guard, I raise the gun to chest level pointing down range, then close and lock the cylinder into the frame.

I cock the hammer with my right thumb and squeeze off the first round. Bright yellow appears at the edge of the dark black center ring of the target 50 ft. away. Even though the Medusa is a double-action pistol that will fire a single bullet with every pull of the trigger, I repeat the single-action process until all six rounds are spent–the final three higher-powered rounds accompanied by a satisfying kick not evident with the first three. More yellow spots appear in the black, nearer the center.

I reload the same mix of calibers, close the cylinder as before, and repeat the process using double-action. When I am finished, my skeptical observer steps up and says, "Pretty unique. Can I try that?" It's a scene that will be repeated many times before the range goes cold for the day.

Unique is exactly the way to describe the Medusa Model 47 revolver, a standard 6-shot revolver from Phillips & Rodgers that chambers, fires and extracts 25 different cartridges in the .38/9mm/.357 ammunition range. This multicaliber firearm is a long-sought solution to a problem worked on by Colt, Smith & Wesson, and other firearms builders for more than a century.

Sharp Ship!

Take a tour of the Navy's new M80 Stiletto!
M80 Stiletto

Built to deliver and support Navy SEAL operations, this high-tech carbon-fiber craft is both beautiful and deadly smart. Get a closer look at the military's floating feat of engineering in this slideshow at Popular Science.

A dramatic departure from earlier military designs, the M80 Stiletto has the potential both to protect troops in combat and to keep the U.S. homeland safer by allowing a greater number of higher-speed patrols without a negative environmental impact. The M-hull’s inherent properties of bow wave suppression, shock mitigation, high speeds and fuel efficiency – all while retaining safety – make it an ideal solution for future navy ships operating locally and in duty areas around the world.

Sugar High!

Launch a Model Rocket with Oreo Cookies!
Sugar Rocket

Food contains an amazing amount of energy. If you don’t believe it, feed candy to some kids and watch them bounce off the walls. Of course, tot-baiting is only one way to turn food energy into noise and destruction.

A king-size Snickers has 541 Calories. That’s Calories with a capital “C,” or 1,000 lowercase calories. A small-“c” calorie represents the energy required to heat one gram of water by one degree Celsius. So that Snickers could theoretically heat a gram of water 541,000 degrees or, more realistically, bring a gallon and a half of water from nearly freezing to nearly boiling.

The energy in food is typically released when, through a complex biochemical pathway, sugars, starches and fats react with oxygen from the lungs. It’s a form of slow-motion burning that, thankfully, rarely involves fire.

But you can liberate the same amount of energy in much less time by mixing the Snickers with a more concentrated source of oxygen—say, the potent oxidizer potassium perchlorate. The result is basically rocket fuel. Ig­nited on an open fireproof table, it burns vigorously, consuming an entire candy bar in a few seconds with a rushing tower of fire. If you could bottle the energy of kids playing and turn it into a Molotov cocktail, this is what it would look like.

Of course, you can’t actually fire a rocket with a Snickers bar; the nuts would clog the nozzle. Oreo cookie filling, however, works very nicely in standard model-rocket engines. (Caution: The Model Rocket Safety Code does not approve of filling rocket motors with highly reactive chlorate-Oreo mixtures.)

Of course, burning calories can't be that easy when you're on a diet!

Warp Speed Ahead!

Warp Speed

In a rush to flee the solar system? Scientists have an interstellar travel plan, but it entails a brief stint outside the known universe.

What is Warp Speed? A spacecraft that travels at faster-than-light speeds by distorting, or “warping,” the fabric of spacetime. Instead of trying to move through space, the warp drive moves space itself. The ship sits inside a bubble of spacetime bound by a negative energy field that races across the cosmos.

1. Fuel Up: Start beyond Earth’s immediate gravitational pull. Convert matter into negative energy (particles with negative mass that are repelled by gravity rather than attracted to it).

2. Curve Spacetime: Emit pulses of negative energy to curve spacetime. Form a sphere around the ship with the energy, insulating passengers in their own private spacetime bubble.

3. Drop Out: The bubble warps spacetime so drastically that it actually slips out of the visible universe. Only a narrow tube of negative energy keeps it tied to our world.

4. Expand Space: Now that the craft is protected in its spacetime bubble, the real work can begin: Expand space behind the bubble at faster-than-light speed, and shrink the space in front.

CLEVER Car!

British CLEVER Car

CLEVER Car CorneringCLEVER Car Engine

It has two seats, three wheels and so far has cost $2.9 million. Students at the University of Bath in western England, who on Monday unveiled the prototype of the CLEVER (Compact Low Emission Vehicle for Urban Transport), hope that it represents a greener future for transport.

The prototype, a skeletal speedster which had safety netting in place of body panels, exhibited the general design and technology of the vehicle rather than its actual, finished appearance.

It has the compactness of a motorcycle but the safety of a car, and cornering is smoothed by a tilting technology developed by mechanical engineering students Matt Barker, 29, Ben Drew, 27 and their instructors.

Equipped to handle both city streets and long-distance highway driving, the vehicle runs on compressed natural gas and is capable of 80-mph speeds with a fuel efficiency of 100mpg!

Check out the article at Fox News.

I can't wait to see the American SUV version! Sure it will only get 50mpg... but it will have lots of extra cargo room, a DVD player, mud tires, and all of the other bells and whistles! WOOT!

Attack at the Speed of Light

Lasers!

After decades of expensive, well-publicized failures, laser weapons may finally be on the horizon. Can scientists end the era of bombs and bullets?

The ray-gun potential of weapons that fire with precision over tremendous distances is far too militarily appealing, particularly at a time when American soldiers are fighting guerrilla foes who melt quickly into the background. “If I could reach into a crowd and take out one or two targets without a puff of dust or a crack of a rifle—if I could fire for a long time, without ever having to reload,” says Marine Corps Major General Bradley Lott, “that’s something the United States Marine Corps would be very, very interested in pursuing.”

X-Racers: NASCAR of the future?

X-Racers

The plane, dubbed the EZ-Rocket, sails through a turn, wings back toward the spectators. Rick Searfoss, the Air Force—trained test pilot and former space-shuttle commander at the controls, glides in silence until he relights one of the two isopropyl-alcohol-powered rocket engines. He banks left, blasting through a high S-curve at 160 mph to come back around parallel to the runway, and swings the rocket's faint blue exhaust toward the cheering crowd.

Sounds cool, I think I'll watch it on T.V. Just something about the plane speeding toward the crowd at 160mph that makes me think, "That's not where I want to be."

Protecting New Orleans - Popular Science Ideas

New Orleans Cat 5

By now you know that engineers had long predicted the cataclysmic flooding that struck New Orleans. But what you might not realize is that Katrina—a category-4 cyclone when it made landfall in Louisiana on August 29—was not the worst-case scenario. That would be a direct hit from a category-5 hurricane, which would send a storm surge over the city’s levees and submerge New Orleans in minutes. Anyone who had ignored evacuation orders would drown.

New Orleans needs more protection than levees alone can offer. But in Louisiana, a comprehensive flood-control program had been repeatedly rebuffed—by environmentalists who fretted over the effects on ecosystems, by fishermen who feared for their livelihood, by engineers dead-locked over competing proposals, and by administrators who dismissed the plans as too expensive.

Katrina changed everything. All ideas—no matter how costly or far-fetched—are back on the table. In the end, officials might opt for a Band-Aid approach. They shouldn’t. Relying solely on patched-up old levees is like asking the U.S. Border Patrol to fend off a full-scale military invasion.

The biggest reason for New Orleans’ weakness to storm surge is the erosion of the coastal wetlands. This erosion is natural, but has been drastically accelerated by man made shipping channels, canals and levees. The channels and canals breach the natural coastal barrier and allow saltwater to seep into the freshwater marshes, killing the plant life that is such a vital shield for the city. The levees prevent the sediment deposits from reaching vital areas, which is why New Orleans is sinking. There has to be a way to protect the city and revitalize the coastal wetlands at the same time.

I like the ideas Popular Science has come up with, for the most part. One question I have is regarding the “subterranean plumbing,” how do you plan on installing this system? Have you ever tried to dig a hole in New Orleans? Seriously, dig a hole just to install a basketball goal, there is water at the bottom of that shallow hole... that’s why no one is buried in the ground here, all in above-ground tombs.

Of course, one has to ask, “Where is all of this money going to come from?”

In 2002, NOLA produced a Special Report regarding the vulnerabilities and worst case scenarios that New Orleans faces. This article is loaded down with graphs, illustrations, and photos. Check it out!

One more thing, check out the above photo... do you think that satellite dish would still be there in a Category 5 Storm?
