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

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.

NASA Receives 461GB of Moon Data Each Day

NASA_LRO_Moon.jpg

Hold onto your hard drive: NASA’s Lunar Reconnaissance Orbiter (LRO) has been sending 461 gigabytes of images and other data back home every day, according to Slashdot. Interestingly, it’s using a 100 Mbps data pipe–specifically, a K-band transmitter called the Traveling Wave Tube Amplifier.

It’s a 13-inch long tube that uses electrodes in a vacuum tube to amplify microwave signals, the report said. L-3 Communications Electron Technologies and NASA’s Glenn Research Center built the device in tandem. 100 Mbps doesn’t sound all that impressive on paper, since wired Ethernet has had that for years–until you release the data is traveling almost 240,000 miles. Suddenly FiOS doesn’t seem all that fast.

NASA Discovers Building Block for Life in Comet

NASA_Comet_Stardust.jpgBack in 2004, NASA’s Stardust spacecraft passed right by Comet Wild 2’s nucleus and collected samples of the dense gas and dust material surrounding the icy center; two years later, a capsule containing those samples separated from the craft and returned to Earth.

Now scientists have discovered a fundamental building block for life–glycine–in those samples, according to NASA. “The discovery of glycine in a comet supports the idea that the fundamental building blocks of life are prevalent in space, and strengthens the argument that life in the universe may be common rather than rare,” said Carl Pilcher, director of the NASA Astrobiology Institute, which co-funded the research.

It’s taken this long because researchers spent two years developing the tools necessary to analyze the tiny sample, and to rule out (via isotopic analysis) that the glycine was from Earth and somehow contaminated the samples. (Image credit: NASA/Stardust rendering)

10 Extreme Cameras for Taking Impossible Shots

Modern consumer cameras can manage almost anything you throw at them, but sometimes even the swankest DSLR just won’t do. In photography, when the conditions get crazy, the cameras get crazier.

Here are ten cameras designed to capture the kinds of images that humans by all means shouldn’t be able to see, and that you and I will probably never have the opportunity—or need—to shoot.

NASA Builds First New Test Rocket in 25 Years

NASA_Rocket.jpgIt’s been a long time coming: NASA has completed the first new test rocket in over a quarter century, in an effort to replace the aging Space Shuttle fleet, according to Space.com.

The new Ares I rockets will eventually take humans back to the moon; this first one will launch on October 31st in a maiden test flight designed to show that the rocket is capable of carrying astronauts inside an Orion spacecraft into orbit. Ares I is a two-stage rocket that consists of a solid-fueled first stage and a larger, liquid-fueled upper stage, the report said.

The rocket stands at 327 feet high, which is about 14 stories taller than a launch-ready shuttle with all rockets attached, according to the article.

NASA plans to retire the shuttle fleet by 2011, replace them with a system of Ares rockets and Orion craft by 2015, and return astronauts to the moon by 2020.

Astronomers Discover Planet Going the Wrong Way

Astronomers have discovered a planet in another solar system 1,000 light years away that orbits its star opposite from the way the star rotates, making it the only planet ever discovered to do so.

The system was discovered by the UK’s Wide Area Search for Planets (WASP) project in collaboration with Geneva Observatory, according to Space.com. It’s also turning out to be quite a curiosity among the 350+ extrasolar planets known to date. The running theory is that the planet, dubbed WASP-17, had a close encounter with a larger one–and the resultant gravitational interaction slung WASP-17 onto its strange course.

“I would have to say this is one of the strangest planets we know about,” said Sara Seager, an astrophysicist at MIT who was not involved in the discovery, in the article. “I think it’s extremely exciting. It’s fascinating that we can study orbits of planets so far away. There’s always theory, but there’s nothing like an observation to really prove it.” (Image credit: NASA/Extrasolar planet artist rendering)

NASA: Build Us a Space Taxi

Hey buddy, need a ride to the moon? NASA plans to invest in the development of commercial passenger transportation services to space, using $50 million of federal economic stimulus funds, according to Reuters.

Agency officials said Monday that aspiring spaceship entrepreneurs will have 45 days to submit proposals, ahead of award announcements before the end of September.

Currently, NASA is spending $500 million to help Space Exploration Technologies and Oribtal Sciences Corp, two U.S. companies, develop rockets and capsules to deliver cargo to the International Space Station, the article said.

Not everyone is happy with the new plan, though. “It’s a little disappointing that (the new program) is only $50 million,” SpaceX founder and chief executive Elon Musk said in the report. “Fifty million is what it costs for one seat on the (Russian) Soyuz.” (Image: NASA/Hubble repair mission)

Kepler Telescope Scores Early Discovery

NASA’s Kepler telescope launched in March and is still undergoing preliminary tests, but that hasn’t stopped it from making an early discovery.

The new telescope is sensitive to light changes enough that scientists were already able to determine that a planet orbiting a distant star has an atmosphere, only shows one side to the sun, and is so hot it glows, according to CNN. That sensitivity “proves we can find Earth-size planets,” said William Borucki, Kepler’s principal science investigator, in the report.

Over the next three and a half years, Kepler will survey thousands of stars in our galaxy in an attempt to find more Earth-sized planets, and get a better sense of how common they are. (Image credit: ESO)

Mars Life Looks Increasingly Unlikely

Despite the discovery of a meteorite on Mars the other day that looks vaguely like the famous one from the 1990s, hopes are beginning to dim for finding life on the red planet, Space.com reports.

That’s because while methane was found in the Martian atmosphere–which led to speculation that something living had produced it–a new study released today in the journal Nature said that the methane plumes were actually concentrated in one spot, the report said. That means they were probably generated by a chemical reaction within the atmosphere, instead of spread out across the atmosphere the way it happens with living beings. And the plumes are also destroyed quickly–within the hour.

“If observations of spatial and temporal variations of methane are confirmed, this would suggest an extraordinarily harsh environment for the survival of organics on the planet,” wrote Franck Lefevre and Francois Forget, of the Universitaire Pierre et Marie Curie in Paris, in the journal.

Astronauts Tool Bag Vaporizes in Earths Atmosphere

NASA_Tool_Bag_ISS_2.jpg

After months of circling the planet and getting ever closer, a lost tool bag that belonged to one of NASA’s astronauts vaporized in a fiery burst as it re-entered Earth’s atmosphere and burned up Monday, according to Space.com.

Last November, the astronaut accidentally lost the tool bag during a spacewalk. At the time, it slowly drifted away from the International Space Station, forever out of reach. Ever since, the tool bag has been orbiting earth–and monitored by the U.S. Air Force’s Joint Space Operations Center, which tracks over 19,000 other pieces of space junk in orbit from Vandenberg Air Force Base in California, the report said.

The tool bag weighed about 30 pounds and contained a scraper tool, grease guns, and trash bags. It was about the size of a small backpack, according to the article. This would have been a perfect video clip for YouTube, if someone could have, well, orbited the Earth and filmed it before burning up with the bag. Guess that wouldn’t have worked out.
