The Kepler space telescope seemed doomed to become space junk back in August, when it lost its ability to accurately and reliably point in any particular direction. Now NASA has a plan that could allow the telescope to keep working
, great news given the fact that all the rest of its hardware is still in good order. Excelsior! — Maggie
Want to read the first research published from NASA's Mars Curiosity expedition? That'll be $20, per paper, for a one-day pass. Or, at least, that's how much it would cost you to read those reports through Science
, the journal that published them. Last Thursday, Michael Eisen, a biologist who founded the open-access journal Public Library of Science, put up a blog post in which he released free pdfs for all five of NASA's Curiosity papers
. Meanwhile, Mother Jones has a profile on Eisen
, which goes more in-depth into his campaign to make taxpayer-funded research more easily available to the taxpayers, themselves. — Maggie
If a Saturn V rocket had ever exploded on the launchpad, it would have been a catastrophic event. NASA engineers once calculated that the resulting fireball would have been 1048 feet wide and would have hit temperatures as high as 2,500 degrees Fahrenheit. In the hopes of not losing astronauts or launch crew to the inferno, NASA tricked out the Apollo launchpad with some safety systems that still exist today, including an underground, rubber-lined bunker that was accessible from the launch platform via a 200-foot twisty slide. (Which almost sounds like fun, until you consider the context.)
Amy Shira Teitel is one of the few people who have been inside the rubber room recently. In the video above, and she shares photos and stories about it in the video above, at her blog, and on Discovery.com.
Are you the kind of person who could lie in bed for 70 days for science? If so, you could make $18,000 in a NASA study of microgravity
. The catch (because lying on your back for 70 days wasn't already enough of a catch): The bed will be tilted 6 degrees towards your head, forcing bodily fluids upwards and replicating what happens to your cardiovascular system in microgravity environments. — Maggie
Here's something new for the BoingBoing evil lair collection — NASA is selling the massive platforms that used to move spacecraft from the hangar to the launchpad at Kennedy Space Center. From The Guardian:
The platforms provided power and umbilical connections to Apollo and the shuttles, and had open sections for flames and rocket exhaust to pass through. "At this point Nasa is looking to gauge interest for potential use of the [platforms] and concepts for potential use," spokeswoman Tracy Young said. Proposals are due by 6 September.
I'm sure you all have some good ideas.
EDIT: I previously understood this story to mean that the whole platform/crawler system was for sale. That appears to be incorrect. You can't have the tread-wheeled vehicle. NASA will be using that. But you can buy the platform that sat on top of the vehicle.

This photo, taken by astronautics grad student and photographer Ved Chirayath, was meant to be a bit of free promotion for NASA and space exploration. It's part of an art exhibition called Physics in Vogue, which combines real science with the style of fashion photography. With the help of a Viking re-enactment troupe and some of his colleagues from the Ames Research Center, he put together a shot that was meant to connect current NASA projects to the exploration-oriented Viking culture. What if two of Earth's greatest explorers met face-to-face?
The photo was done on Chirayath's own time, using funds from two arts grants that had nothing to do with NASA. But it has become the center of an extensive investigation initiated by Senator Chuck Grassley, aimed at discovering whether dastardly NASA scientists were using taxpayer money to make whimsical photos. They weren't. Ironically, though, the investigation did use taxpayer money. More, Chirayath estimates, than it would have cost him to get such a photo done by a professional.
Space educator Sawyer “@thenasaman” Rosenstein, 19, is a hardcore space fan. His enthusiasm for space flight was captured in a 2011 Boing Boing special feature, and shines weekly in his “Talking Space” podcast. He traveled to Florida for the opening of the new permanent exhibit of Shuttle Atlantis at Kennedy Space Center, and shared photos with us. All images in this review are Sawyer’s. —Xeni Jardin.

On Sunday, NASA launched three PhoneSats into orbit. House in a standard "cubesat" structures, a Google-HTC Nexus One serves as the onboard computer and sensor system, taking photos of Earth. Aamateur radio operators are monitoring the transmissions and picking up data packets that will be recombined here on Earth. According to a NASA press release, the use of commercial-of-the-shelf parts, a minimalist design, and limited mission requirements kept the cost of each satellite as low as $3500.

Aerospace contractor Bo Jiang
, who is accused by U.S. Rep. Frank Wolf
(R-VA) of being a spy, made a first appearance in federal court on Monday. The Chinese national worked on contract at NASA's Langley's Research Center in Hampton, VA.
Federal agents grabbed him over the weekend just as he was boarding a flight from Dulles airport (in DC) to Beijing. He is charged with making false statements to U.S. authorities by failing to disclose all of the electronic devices he was carrying on his one-way flight, and has since been jailed.

The Lunar Orbiter Image Recovery Project
(LOIRP) was started by Dennis Wingo and Keith Cowing in 2008. They obtained the original analog tape drives from lunar missions in the '60s, which were literally covered in dust in a farmer’s barn, and they also got their hands on a complete collection of Lunar Orbiter analog data tapes that held a full set of all images carried back to Earth by the five spacecraft that flew between 1966 and 67.
Amazing, historic stuff. But all of these old media formats are fragile, and preservation can be a long and tedious process.
Cowing and Wingo funded the archival effort themselves in the beginning, then secured some funding from NASA. But the NASA funding was modest, and has run out; the guys have been funding the project themselves, and they don't have the resources they need. They have exceeded the requirements of NASA’s funding, but just haven't been able to retrieve and digitally archive all of these irreplaceable historic space images—yet.
So they're crowdsourcing funds on RocketHub. They've raised about 1/3 of their goal at the time of this blog post, and they have only 5 days left.
Miles O'Brien did a "This week in Space" webshow episode about the project back in 2010; check it out above.
Below, more on the project from Cowing, who is also the guy behind NASAwatch.

Gravity isn't uniform. Denser planets and objects in space — that is, things with more mass to them — experience a stronger pull of gravity. But even if you zoom in to the level of a single planet (or, in this case, our Moon), gravity isn't uniform all the way around. That's because the mass of the Moon isn't uniform, either. It varies, along with the topography. In some places, the Moon's crust is thicker. Those places have more mass, and thus, more gravitational pull.
This map, showing changes in density and gravity across the surface of the Moon, was made from data collected by Ebb and Flow — a matched set of NASA probes that mapped the Moon's gravitational field before being intentionally crashed on its surface last December. By measuring the gravitational field, these probes told us a lot about how the density of the Moon varies which, in turn, tells us a lot about topography.
You can read more about the probes (and see some videos they took of the lunar surface) at the NASA Visualization Explorer.
In 2010, a group of scientists claimed to have found bacteria that could build its DNA using arsenic, instead of the phosphorous used by the rest of Earth's life forms. Within days, the research behind "arsenic life" was under serious scrutiny and we now know that it was totally wrong. But the work was peer-reviewed. It was sponsored by NASA. How do so many experts make such a big mistake?
Dan Vergano at USA Today has an excellent article looking at just that — and it includes the peer review comments that helped the arsenic life paper get published. Though normally secret, Vergano got a hold of them through a Freedom of Information Act request. — Maggie
