Speaks for itself, doesn't it? NASA:
When the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired this image on December 7, 2013, thick haze stretched from Beijing to Shanghai, a distance of about 1,200 kilometers (750 miles). For comparison, that is about the distance between Boston, Massachusetts, and Raleigh, North Carolina. The brightest areas are clouds or fog. Polluted air appears gray. While northeastern China often faces outbreaks of extreme smog, it is less common for pollution to spread so far south.
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!
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.
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.
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.

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.

From NASA's Image of the Day blog: "This face-on galaxy, lying 45 million light-years away from Earth in the southern constellation of Fornax (The Furnace), is particularly attractive for astronomers. NGC 1097 is a Seyfert galaxy. Lurking at the very center of the galaxy, a supermassive black hole 100 million times the mass of our sun is gradually sucking in the matter around it. The area immediately around the black hole shines powerfully with radiation coming from the material falling in."

It was forty years today (at 22:54:37 UT) that human beings left the moon for the last time. Miles O’Brien remembers Commander Gene Cernan’s last words from the moon, lofty, rehearsed and memorized: “as we leave the Moon at Taurus-Littrow, we leave as we came and, God willing, as we shall return: with peace and hope for all mankind.”

Today is the 40th anniversary of the "Blue Marble," the iconic photo taken by the crew of the Apollo 17. More on the photo and its impact at LIFE.com and Wikipedia. Here's NASA's original caption:
View of the Earth as seen by the Apollo 17 crew traveling toward the moon. This translunar coast photograph extends from the Mediterranean Sea area to the Antarctica south polar ice cap. This is the first time the Apollo trajectory made it possible to photograph the south polar ice cap. Note the heavy cloud cover in the Southern Hemisphere. Almost the entire coastline of Africa is clearly visible. The Arabian Peninsula can be seen at the northeastern edge of Africa. The large island off the coast of Africa is Madagascar. The Asian mainland is on the horizon toward the northeast."
Here's the best way I can sum up this story: Yes, some NASA scientists are working on a design for a warp drive. No, that doesn't mean warp drives are real.
Warp drives — as a purely theoretical thing and/or science-fiction plot device — involve manipulating space-time to allow a spaceship to go faster than the speed of light. It's basically loophole that would allow you to get around those pesky laws of physics. Swiss bank account:taxes::Warp drives:speed of light. You get the picture.
Harold White of NASA’s Johnson Space Center is currently leading an effort to design a warp drive space ship. But, as Amy Teitel explains in a story for Vice's Motherboard, the fact that this is happening does not necessarily mean a real working warp drive is possible. It's more about the fact that NASA is partly in the business of letting really smart people try things that are kind of crazy and unlikely, if they can back up the idea with a reasonably plausible hypothesis. Speculative research is a thing that happens.
The problem is that breaking the light barrier isn’t at all like breaking the sound barrier. The sound barrier–properly, the aerodynamic effects of pressure waves interacting with a body as it approaches the speed of sound–was broken with a cleverly engineered aircraft and an at-the-time state of the art rocket engine.
Bell’s X-1 was, importantly, a physical aircraft made of matter, not made of sound. But the atoms and molecules that make up all matter are connected by electromagnetic fields, and that’s the same stuff that light is made of. So when it comes to breaking the light barrier, it’s like breaking through light with light (sort of… ask Brian Greene). As NASA poses the question, “How can an object travel faster than that which links its atoms?” It’s a very different matter.
Another issue special relativity brings up is the light speed barrier. Moving takes energy, and the faster you move the more energy you use. So, theoretically, to move at the cosmic speed limit of light you need an infinite amount of energy. That’s a distinct barrier if there ever was one.

What might the Curiosity rover find on Mars? So many cool things. Maybe friends that hug your face! Maybe Nixon's secret tapes! Or maybe even something less easily fit into song lyrics, like significant amounts of Martian methane.

Just before Thanksgiving, the lead mission scientist for the Curiosity rover told NPR that his team had found something that would "be one for the history books." Naturally, we all began speculating about the presence of life, giant obelisks, and half-buried Statues of Liberty
. Yesterday, however, a different NASA spokesman basically asked the world to not get its hopes up too high, revising the level of importance down from "earthshaking" to "interesting"
. So far, nobody has said what, exactly, was discovered. (Via Colin Schultz)
Space.com spoke to space policy expert John Logsdon
, a professor emeritus at George Washington University, about rumors that NASA may soon unveil new manned moon missions.
"Plans have probably already been cleared with the Obama Administration but have been kept under wraps in case Republican candidate Mitt Romney won," according to Space.com.
As the Independent notes, these comments sync with remarks by NASA deputy chief Lori Garver at a conference in September. (via Jenny Winder)
This computer simulation uses what we know about physical forces in the universe to model how a galaxy might have been born, and how it might grow over 13.5 billion years.
This cosmological simulation follows the development of a single disk galaxy over about 13.5 billion years, from shortly after the Big Bang to the present time. Colors indicate old stars (red), young stars (white and bright blue) and the distribution of gas density (pale blue); the view is 300,000 light-years across. The simulation ran on the Pleiades supercomputer at NASA's Ames Research Center in Moffett Field, Calif., and required about 1 million CPU hours. It assumes a universe dominated by dark energy and dark matter.
The result is a beautiful (if silent) video that is significantly labeled as public domain. It seemed like something you guys might enjoy playing around with.
