Artists Attempt At 'Zero Gravity Art' Ends in Nausea



Three British artists, a black cat, and a mouse spent Tuesday aboard a Russian aircraft nicknamed the "vomit Comet" in pursuit of Dalí-esque "zero gravity" art. The plane is usually used to train astronauts, and simulates weightlessness by doing steep ascents and dives, something akin to a giant roller coaster ride.

Apparently only one artist, Nasser Azam, escaped debilitating nausea, and he finished Francis Bacon-inspired paintings with oil pastels. The cat and mouse were supposed to chase each other in zero gravity while one of the artists filmed them. However, both the cat and the artist became ill after about 3 'loops' and had to be secured to the plane for the remainder of the flight. In summary, Nasser Azam, the only artist not to become ill said, "Quite frankly it was euphoric, there were instances when I was painting upside down. We'll go and have a few vodkas - a few stiff ones..."

The flight, which was provided to the artists free of charge, was a unique cultural exchange between the two countries, which have had strained relations since the 2006 poisoning of a prominent Kremlin critic on British soil, and the forced closing of two British council offices in Russia earlier this year.

Get Married in Space for Just $2M

Get Married in Space, and for Only $2Million

Getting your ashes shot into space when you die is so 2007. The space fad for 2008 is weddings! Or at least signing up for them. A Japanese company called First Advantage has joined forces with an American aerospace firm called Rocketplane to offer weddings 100 kilometers (62 miles) above earth. First Advantage now joins Richard Branson's Virgin Galactic in the space-marriage racket.

The $2 million covers not only the flight on the Rocket Plane XP, but also a ground-based party where friends and family can watch a live stream of the zero-G ceremony. The company will even even throw in a wedding dress! The first ceremonies will take place in 2011, beginning with the wedding of Cindy Cashman, entrepreneur and author, and Mitch Walling.

Northern Lights May Increasingly Interfere With GPS



GPS units are not infallible.

Stories abound of users blindly following poor GPS directions (based on improperly developed maps) onto train tracks, off marked roads, and even into a nasty part of town.

Now, there's a brand new problem: interference from the Northern Lights, or Aurora Borealis, the natural lightshow seen near the Earth's poles when high-speed particles from the Sun hit the atmosphere. The natural light show distorts the signals from Global Positioning Satellites (GPS) that are 12,600 miles overhead. With increasing solar activity expected in the coming years, the bright lights could foul up navigation devices at an increasing rate.

The last peak of solar activity came in 2000, which is before portable navigation devices were popular, so users haven't experienced this kind of interference to date. The next peak is expected in 2012, with increasing activity each year until then.

According to a report in the American Geophysical Union's 'International Journal of Space Weather' (their Summer Fun issue is a must-read), tests conducted in Norway during Northern Light activity showed GPS units were not able to precisely identify the roads the researchers were on. Sometimes the units lost their signal entirely.

The global positioning satellites hover in fixed positions 12,600 miles above sea level. For the portable navigation units that people use in their cars, boats and planes to work, they must be able to receive unimpeded signals from these satellites. When the Northern Lights are in play, the Earth's ionosphere gets "lumpy," rendering the signals inaccurate.

Navigation device makers say this won't cause a dangerous situation for drivers as long as they use common sense while behind the wheel. So, mainly, the same common sense that (we hope) will keep you from driving off the road into a river, either. [Source: Telegraph.co.uk.]

Mars Phoenix Lander Discovers Ice on Mars


It's only fitting that the glorious news of water ice on Mars was broken over Twitter last night, via the Mars Phoenix lander's own first-person ramblings. Apparently, Mars Phoenix was keeping an eye on some white patches it uncovered the other day, only to discover they'd disappeared today. According to the scientist folk over at NASA, that means those white patches must've been ice, which dissipated once uncovered.

Now Mars Phoenix still has the considerable task of uncovering more ice and sampling it, but the mission is ahead of schedule and NASA has already identified a hard patch of ground it wants to dig into. Congrats to Mars Phoenix and all the fine folks at NASA. Now be sure to watch out for the cave-dwelling little green men! [Source: Phoenix Mars Mission via Wired Science]

Mars Probe Hampered By Radio Glitch


The first thing the news Mars lander Phoenix wanted to do when it reached the red planet was stretch its arm. (What do you typically do after a long flight?)

This first step was hampered, though, by a radio communications glitch that delayed its activity for most of Tuesday. The glitch, however, was aboard the Reconnaissance, the Mars orbiter responsible for relaying data between the planet surface and mission control here on cozy planet Earth. The extremely smart folks at NASA's Jet Propulsion Lab who head up the Mars lander program say the radio on the orbiter likely switched its radio off due to a cosmic ray.

Even though the glitch has been fixed, a second orbiter, the Odyssey, will be used for now to relay information to Phoenix. The lander has settled on a promising patch of Martian soil that looks like it may contain ice about one foot below the surface, which could mean evidence of life. The arm will be used to start digging the surface to collect samples for analysis.

The effort to explore Mars has been hampered by unexpected glitches before. A major computer malfunction severely hampered the abilities of the polar lander in 1999. Another craft intended to study Mars' atmosphere wasn't properly calibrated, which caused it to burn up as it approached the Red Planet. [Source: CNN]

Richard Branson to Officiate First Wedding In Space

Branson May Conduct First Galactic Wedding

If you were ponying up $100,000-per-seat for you and someone special to take a ride on Richard Branson's SpaceShipTwo into the outer atmosphere, chances are it'd be a moment that you'd have a hard time forgetting. That said, some couples are taking things a bit further to make that journey a memorable one. One as-yet-identified couple has plans to get married while out there, and it looks like Branson might just be the man for the job.

Virgin Galactic C.E.O. Branson, who is ordained, has already conducted a wedding while in mid-flight on a Virgin airplane (which was appropriately en-route to Las Vegas). The set of intergalactic nuptials to be exchanged on the upcoming SpaceShipTwo flight will be the first extra-atmospheric wedding. In addition to the nuptial couple, Virgin Galactic advister George Whitesides and his new wife, Loretta Hidalgo will be getting the first honeymoon in space.

So, if you thought your bride-to-be would be impressed with that trip to Acapulco, better think again! [Source: Daily Mail]

German Schoolboy Who Corrected NASA Is Wrong, Says NASA, ESA

german schoolboy asteroid

A possible 'Armageddon'-like disaster has been predicted and averted, all within a few hours today, as NASA scientists confirmed their original estimate of a possible asteroid collision with Earth to be slight, even though a 13-year-old German schoolboy found himself fêted across the Internet for "correcting" the estimate. Using open source software he downloaded, the boy stated a high probability of impact for the asteroid.

NASA's numbers spell out a 1 in 45,000 chance of the asteroid Apophis hitting Earth in 2036. The schoolboy, from Potsdam, Germany, tried to factor in the odds of the asteroid actually hitting a man-made satellite during its first close pass to our planet in 2029, which he said could alter the trajectory and put it on course with Earth during its return trip, with a 1 in 450 chance of hitting our friendly planet.

The story made the rounds today across the Internet, even getting picked up by various international press outlets. Now, it seems, NASA and the European Space Agency (ESA) are refuting the boy's prediction, saying the odds of the asteroid hitting a satellite were not properly calculated.

Phew. That was a close one. [Sources: The Register and IT Week.]

Low(er) Cost Commercial Space Flight Prototype Revealed

Low(er) Cost Commercial Space Flight Prototype Revealed

SpaceShipOne from Scaled Composites was the first, the first commercial ship to probe the (sub-orbital) heavens. It's successor, SpaceshipTwo has been revealed and, for just $200,000 each, you and five friends can sign up for a two and a half hour trip waaay up there. It'd be the trip of a lifetime, but at a cost many would have to spend their entire lives saving for. Now another company, XCOR, has unveiled plans for smaller, quicker, and (presumably) cheaper flights by 2010.

The ship is called the Lynx and seats just two, one of whom has to be the pilot, of course. This means that you won't be able to take any friends along, but the relative light weight and economy of the ship means just a 25-minute round-trip to the outer limits and the potential for multiple flights in a single day. No specific word on cost just yet, but if it's not considerably more affordable than the offerings from Scaled Composites we can't see this one getting off the ground.

New Lunar Rover Could Build Roads On the Moon


If you've been wondering what your tax dollars are being spent on over at NASA just take a quick look at this video. The new lunar rover, dubbed Chariot because astronauts ride it while standing on the back, is getting put through its paces at the Lunar Yard at the Johnson Space Center in Houston, Texas.

The six-wheeled Chariot tops out at 20-miles-per-hour and can accept a range of interchangeable attachments, including plows and drills. Scientists have so far been happy with the results, and say it has had no problem handling the moon-like loose surface at the Lunar Yard, which is a good thing since the Chariot is designed to one day build roads or drill for minerals on moon's surface.

Even though the first build has exceeded the engineers expectations, it will undergo further improvements, including wheels that can move up or down independently of one another for greater agility and a smoother ride.

Space Pinwheel Could Kill Us All With Gamma Rays

Space Pinwheel Could Kill Us All With Gamma RaysIn what can only be described as a storyline that sounds more appropriate in a science fiction film than a news story, scientists are reporting that a "pinwheel" in outer space, 8,000 light years away, could potentially kill us all with a burst of gamma ray radiation.

The spiral appearance is actually formed by two orbiting stars pulling each other apart slowly, contributing solar gasses in a twisting form between them. It just so happens that this pinwheel's center is pointing almost directly at us and, when when the stars go supernova (exploding at the end of their life), the gamma ray energy they expel could be focused by the pinwheel and directed at us.

The stars are roughly 8,000 light years away, which is a massive distance. But, despite that distance, if we were to be struck by the resulting gamma radiation, it could burn off part of our atmosphere and cause drastic changes to our climate and way of life. Most frightening of all is that we'd have absolutely no warning whatsoever since the gamma rays travel at the speed of light.

But, don't freak out just yet. Scientists aren't sure that the gamma ray burst would even happen and, if it did, a direct hit on Earth is a long-shot at best.

Space Balloons Deliver Cell Phone Service to Rural America

The same thing that sent the Hindenburg zeppelin skyward (and dramatically brought it down) could be the solution to providing cell phone coverage to rural areas across America, according to a Phoenix, Ariz.-based company that launches six-pound transmitters into the stratosphere with the help of hydrogen-filled balloons.

According to Space Data Corporation's Jerry Knoblach, the best way to provide cell phone service to America's often underserved rural areas is not by stringing along more cable wire or building expensive cell phone towers – which wouldn't be cost effective since so few customers equals very low revenues. Instead, the solution, as Knoblach sees it, is to send up these balloons, which, amazingly, are not expected to be anything close to permanent. In fact, the average lifecycle of one of these hydrogen balloons is about one day.

The interesting thing that could be inflating Jerry Knoblach's fortunes is interest from Google, which as a part of its push into wireless services may cooperate with Space Data Corporation or even buy it out.

Space Data Corporation is constantly making new balloons -- about 10 balloons per day -- and, believe it or not, relies on a network of strategically placed regular folks such as dairy farmers who launch the devices at specific locations and times.

When the transmitters come down, it's up to a network of volunteers to seek them out and pick them up, returning them to the company for a $100 reward. They use GPS to find the transmitters, which descend gently on parachutes after being separated from the balloon, which rises higher into the atmosphere until it bursts into tiny pieces, which Knoblach says are harmless.

Space Data Corporation is able to adjust the direction of the balloons and their overall trajectory is pretty well easy to predict and monitor, so this isn't just like letting a regular balloon go and hoping it ends up somewhere interesting.

Each balloon travels 20 miles into the stratosphere and can bring service to an area that would otherwise need 40 cell towers.

Spy Satellite Splashdown Point Identified (With Map)

Spy Satellite Landing Site Map

In what has become a highly publicized excuse to use some of their explosive toys, the U.S. Navy is planning to shoot a disabled spy satellite out of the starry skies tomorrow morning. Whether they'll even succeed in hitting the thing is a topic of debate, but assuming they do, there's the question of where the debris will land -- not to mention the potential toxic gas cloud created by the 1,000lbs of fuel still on-board. To this effect, the Navy has issued a warning to stay out of a 1,400-mile area in the Pacific.

All flights are prohibited from this area at any altitude from the hours of 2:30 to 5:00 am tomorrow morning local time. As you can see from the above map (viewable in Google Earth via this kmz file courtesy of Alan Clegg) the area includes a region that is, by our accounts, is fairly close to Hawaii. We're sure the Navy has this thing completely in the bag, but that said, just this once we're happy to not be sunning ourselves on the beaches of Maui.

Astronomers Find Solar System Like Our Own

Astronomers Find Solar System Like Our Own
Last week, astronomers announced that they had discovered a solar system that was "like our own" about 5,000 light years away. And, of course, by like our own they mean that it might be... potentially... kinda-sorta... similar in some respects... to our own solar system.

The new system has a red star at the center about half the mass of our own sun and is orbited by at least two planets. The two planets discovered are large gas giants, but unlike previously discovered planetary systems, they're orbiting farther out from their star, allowing room for potential smaller rocky planets to exist.

One planet is about two-thirds the size the Jupiter, while the second is roughly 90 percent of the size of Saturn. Both planets in the new solar system orbit at a much shorter distance from their sun than either Saturn or Jupiter orbit from our sun.

The most amazing part of the discovery, however,is that some of the most important data was produced by a pair of amateur astronomers from Auckland, New Zealand. Jennie McCormick and Grant Christie were able to calculate not only the mass of the star and the planets, but also an approximation of their orbits -- all by using a simple 10-inch Meade telescope in Ms. McCormick's shed.

Until now. all work on extra-solar planets was done at massive multi-million dollar telescopes, which just proves that even expensive astronomical equipment is not immune to the democratization of resources that advances in technology have aleady brought to music-, film-, and video-creation, among other previously expensive and hard-to-break-into endeavors.

U.S. May Just Shoot Down Broken Spy Satellite

US to shoot down spy satellite

The Pentagon plans to fire a missile into space to dismantle a 5,000-pound broken U.S. spy satellite carrying sophisticated imaging and computer equipment. We reported on this story back in January, and government officials project that the satellite will crash somewhere in North America in early March.

Launched late last year, the spy satellite quickly lost power and all control systems failed. The Navy will likely destroy the satellite to avoid the danger of falling debris and the satellite's dangerous load of rocket fuel. Air Force General Gene Renuart said, "It's really just a big thing falling on the ground that we want to make sure we're prepared for."

Beatles' 'Across the Universe' to Be Blasted Into Space


Picture this: Aliens on a distant planet stopping in their tracks, turning to the sky and then holding hands and swaying to The Beatles "Across the Universe." The Fab Four fans at NASA will be hoping for that result this Monday when they beam the song at 186,000 miles per second at the North Star, Polaris, via the Deep Space Network.

Set to be a multiple anniversary on Monday, the song's space release marks the original recording of the Beatles classic 40 years ago, NASA's 50th anniversary, 45 years of the Deep Space Network, and the launching of Explorer 1 (the first U.S. satellite). John Lennon's widow Yoko Ono sent her congratulations and encouragement to the space agency saying, "I see this as the beginning of the new age in which we will communicate with billions of planets across the universe." We're just hoping we communicate with more than billions of planets, since we're pretty sure they are non-sentient.

Fans are encouraged to participate by cranking up their stereos (the neighbors won't mind since it's a stellar occasion) at midnight GMT (that's 7pm Eastern Standard Time) on Monday the 4th.
