European Space Agency launches flood-predicting, earth monitoring satellite

by Laura June posted Nov 3rd 2009 at 12:01PM

On Sunday (the first of November) the European Space Agency launched a new satellite from a Russian rocket. This one, named the European Soil Moisture and Ocean Salinity (SMOS) satellite has a few very important jobs to do. For the next 3-5 years, the satellite will gather data about the circulation patterns in Earth's oceans and the moisture in its soil. The collected information will hopefully be used to forecast weather patterns such as droughts and flood risks. Check out the video after the break for a detailed explanation and a peek at the satellite of love itself.

Ion propulsion engine could take you to Mars in 39 days

by Vladislav Savov posted Oct 20th 2009 at 10:31AM

Ready for some interplanetary exploration? We've had the force shields, currency, and refuel stations all sorted out for a while, and now here come the ion thrusters we've been missing to make manned trips to Mars really viable. Currently, a return journey to Mars can take up to two years, with crew members having to wait a full year for the planets to realign, but with ion propulsion -- which uses electricity to accelerate ions and produce small but longevous thrust -- ships can get there within a reasonably tight 39-day window. Ion propulsion rocket engines were first deployed successfully by NASA in the Deep Space 1 probe in 1998, and the latest iteration's successful Earth-bound testing has led to plans for a flight to the moon and use on the International Space Station as test scenarios for the technology. It's all still very much in the early stages, of course, but should all that testing, checking, and refinement bear fruit, we might finally have a whole new world to colonize and sell sneakers on.

Physicist wants to test Hyperdrive Propulsion in Large Hadron Collider

by Joseph L. Flatley posted Oct 11th 2009 at 12:14AM

How come news can never come out of the Large Hadron Collider that doesn't remind us of our planet's impending SciFi Techno-Apocalypse(tm)? When not busy being called a doomsday machine, being bedeviled by hackers and Chuck Norris (yuck!), or just plain failing, the facility could be used to test "hyperdrive" spacecraft propulsion. Seriously! And you know what that means -- someone is planning on escaping the planet, and fast. A physicist named Franklin Felber has been musing over a little known German paper from the 1920s ("The Foundations of Physics" by David Hilbert) which states, in part, that under certain conditions a stationary mass should repel a relativistic particle. If this is true, Felber, concludes, then shouldn't a relativistic particle repel a stationary mass? According to MIT's Technology Review, the LHC would be the perfect place to test this idea: Felber could "set up a test mass next to the beam line and measure the forces on it as the particles whiz past." The experiment could be run in tandem with the collider's other work -- and who knows? Mankind may soon be on its way to the stars at near-light speeds. Let's just hope we figure this out before the robots take over.

NASA LCROSS moon impact in T-minus 15, water discovery expected in T-minus 19 (update: video!)

by Thomas Ricker posted Oct 9th 2009 at 7:15AM

NASA's LCROSS (Lunar CRater Observing and Sensing Satellite) mission is coming to a glorious end. The mission launched on June 18, 2009 is just minutes away from making dual-impact on the face of the moon. The first impact sees the Centaur craft hitting the surface at a speed of about 1 mile per second ejecting about 350 tons of debris from a crater about 20-30-meters in diameter and 2- to 4-meters deep. A second Shepherding spacecraft will pass through the debris plume 4 minutes later, collecting and relaying data back to Earth in real-time before meeting its end. With any luck, we'll know shortly if the moon contains the water-ice theorized by scientists... and cheese. While the obvious use of lunar-based water is to sate the thirst of astronauts, it could also be used be make fuel for off-Earth exploration. Hit the read link for live streaming of the mission from NASA -- first impact occurs at 07:31:19 AM EDT.

Update: Impact occurred... are we still here? Data is now being analyzed and NASA is expected to know the facts in about an hour. Post-impact news conference scheduled for 10:00 AM EDT.

Update 2: Video added after the break showing the final minutes before impact. The highlight seems to be the denied high-5 at 5:00 minutes in.

Video: NASA rockets inflatable heat shield 124 miles up, deploys it successfully

by Tim Stevens posted Aug 24th 2009 at 8:25AM

Space is mighty cool and the Earth's atmosphere isn't particularly hot either (most of it, anyway), but when you transition from one to the other a lot of friction can be generated. NASA typically uses gas-generating ablative shields for smaller orbiters and of course everyone is familiar with the silica tiles on the bottom of the space shuttle, but now it's tested a rather more lightweight and compact option: an inflatable shield. It's comprised of layers of silicon-coated kevlar fabric that, at least for this initial test, inflates in 90 seconds and forms a sort of saucer shape that's just perfect for keeping MUFON's phone lines busy. There's a dizzying video of it being blasted out of the atmosphere just after the break, and we think you'll be seeing plenty more of this tech deployed on future martian landers and the like.

Infrared sensors hit 16 megapixels, can now spy on an entire hemisphere

by Vladislav Savov posted Aug 13th 2009 at 5:12AM

Aerospace and defense manufacturer Raytheon wants everyone to know it has developed the world's first 16 megapixel infrared sensor, which is set for a life of orbiting the Earth and generally being a lot more useful than lesser models. With its higher resolution, the unit is able to cover an entire half of the planet without "blinking" to relocate its focus, and should be warmly received by meteorologists, astronomists and military types, all craving for a bit more real-time reconnaissance. We advise wide-brimmed tin foil hats to shield your body heat from these Sauron-like satellites while working on those plans for a global uprising of the proletariat.

Orbiting fuel stations proposed for trips to the Moon, Mars, and beyond

by Vladislav Savov posted Aug 5th 2009 at 1:51AM

A US government panel, summoned by el presidente to review the future of human space travel, has expressed strong support for introducing fuel depots into Earth's orbit. Refueling between stops is expected to cut down significantly on the weight of spacecraft and, accordingly, eliminate the need to engineer ever more powerful rockets to launch missions. It would then be up to private companies to compete -- and NASA already knows a thing or two about privatizing space missions -- by reducing costs and developing more efficient methods. While by no means the only potion NASA has bubbling, if the panel concludes in favor of orbiting gas stations, they will form the backbone of all future extraterrestrial exploration. So we're just letting you know in advance -- we're nice like that.

Transparent aluminum! Would that be worth somethin' to ya, eh?

by Darren Murph posted Aug 4th 2009 at 1:44AM

It's hard to say if boffins at Oxford University got their inspiration from Nimoy and Co., but one thing's for sure: they aren't joking about the creation of transparent aluminum. In what can only be described as a breakthrough for the ages, a team of mad scientists across the way have created "a completely new state of matter nobody has seen before" by blasting aluminum walls (around one-inch thick) with brief pulses of soft X-ray light, each of which is "more powerful than the output of a power plant that provides electricity to a whole city." For approximately 40 femtoseconds, an "invisible effect" is seen, giving the gurus hope that their experiment could lead to new studies in exotic states of matter. For a taste of exactly what we mean, feel free to voice command your PC to jump past the break. Or use the keyboard, if you're feeling quaint.

Aabar Investments takes 32 percent stake in Virgin Galactic, we're still not cool enough to go to space

by Laura June posted Jul 28th 2009 at 8:06PM

United Arab Emirates company Aabar Investments and today announced that it would be taking a 32 percent stake in Richard Branson's Virgin Galactic space tourism venture, a deal worth about $280 million dollars. Though the deal has yet to be approved by US regulatory agencies, Aabar, which is an investment vehicle for Abu Dhabi's government, said that it plans to build a spaceport in the capital city, and that it's committed an addition $100 million to fund satellite launch capabilites. The deal gives Aabar the regional rights to host tourism as well as scientific research flights. When asked how they felt about having Richard Branson hanging around their city, reps from Aabar said, "King Crazy? We love that guy!"

"Flying laptop" spacecraft could "transform" in space, sort of

by Donald Melanson posted Jul 22nd 2009 at 5:41AM

Impressive as they are, satellites and space probes aren't always the most versatile pieces of equipment once they're up in orbit. A new satellite developed by researchers from the University of Stuttgart's Institute of Space Systems looks set to shake things up in a pretty big way when it launches in 2012, however, even if it's not quite the "transforming" space probe that you might be imagining. Described as a "flying laptop," the satellite promises to pack a vast array of instruments and sensors, including cameras, multispectral imagers, star trackers, and GPS receivers, to name a few, all of which can apparently be completely reconfigured on the fly in space. That, the researchers say, could let the satellite switch from, say, an atmospheric pollution sensor to a near-Earth asteroid detector, an even open up some new commercial possibilities, with different groups able to rent out the satellite to perform various tasks.

Apollo 11 moon mission to be recreated on the web

by Darren Murph posted Jul 13th 2009 at 9:19AM

While the shuttle Endeavour is having a tough time getting off of the launch pad, the Apollo 11 moon mission should proceed as scheduled later this week. Some 40 years after Neil Armstrong and a host of behind-the-scenes workers at NASA made JFK's vision a reality, WeChooseTheMoon.org is being launched to recreate the whole spectacle. Starting a full 90 minutes prior to the 40th anniversary (that's 8:02AM on July 16th), the site will be fully operational, tracking the capsule's route from Earth to the moon. Reportedly, visitors will be able to peek "animated recreations of key events from the four-day mission, including when Apollo 11 first orbits the moon and when the lunar module separates from the command module." If you're one of those who remembers "exactly where you were on that fateful day," you should probably queue up a Google alert and bookmark your browser to relive the whole experience again.

Motorola's Aura Celestial Edition soon taking "giant leaps" for "mankind"

by Darren Murph posted Jul 2nd 2009 at 8:21AM

Here's a fact: the world really doesn't need another mildly tweaked Aura. Sorry, it just doesn't. That being true and all, we're still pretty jazzed to see Motorola giving the ultra-luxurious handset another go with the moon-themed Celestial Edition. Word on the street has it that this here handset won't deviate much from the predecessor, but it will come pre-loaded with multimedia from the original moon landing mission, a laser etched quote honoring the 40th anniversary of the journey and a price tag that's far, far beyond stratospheric. We're told that it's all set to go on sale next month, but good luck finding one.

Video: Japanese astronaut surfs through space on 'flying carpet'

by Thomas Ricker posted May 20th 2009 at 5:20AM

The Japanese can turn pretty much anything into a variety show. So it's no real surprise to hear that the Japanese public have issued a set of 16 zero-gravity challenges to be carried out by Jaxa astronaut, Koichi Wakata, during his time at the International Space Station. Tasks included folding laundry, applying eye-drops, and attempting to ride a "flying carpet;" the latter accomplished with some adhesive tape and a full-size bathroom mat. Seriously, shaka brah. Check the surf and full length videos after the break.

Quantum cryptography: now ready for space travel

by Darren Murph posted May 4th 2009 at 7:37AM

It's been awhile since we've heard of any major advancements in the world of quantum cryptography, but at long last the silence is being broken by a squad of jubilant Austrian physicists. As the story goes, a team from Austria's Institute for Quantum Optics and Quantum Information (IQOQI) managed to send "entangled photons" 90 miles between the Spanish islands of Las Palmas and the Balearics. Calling the ephemeral test successful, the crew has boldly asserted that it's now feasible to send "this kind of unbreakable encrypted communication through space using satellites." Funny -- last we remember, quantum cryptography still had a few kinks to work through here beneath the stratosphere.

Virgin Galactic's WhiteKnightTwo caught mid-flight on video

by Ross Miller posted May 2nd 2009 at 1:23PM

In case you were wondering if Virgin Galactic's efforts at space tourism are still going strong, the company's released new footage from a recent test flight of its WhiteKnightTwo near its Mojave headquarters. Much longer and higher res than the last bit of video we had, it also provides some new aerial shots of it mid-flight. The craft's public debut will be a fly over at the Virgin Galactic Spaceport America groundbreaking ceremony next month, so until then, navigate your browser to after the break for the feature presentation.
