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.
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.Read the rest
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.

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.

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.
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.

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.”Read the rest
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.

"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.
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.
"A giant planet with a liquid interior full of liquid beef and pork, into which a thousand earths would fit."
Darren Cullen of Spelling Mistakes Cost Lives and friend Mark Tolson edited together this 'lost episode' of Carl Sagan's Cosmos, about a fabled Meat Planet, with details of its famous pork volcano, Mount Sustenance, "well-known to astronomers since the time of Galileo."
If NASA would focus on the important planets, the delicious bacon-y ones like this, perhaps we'd have a real future in space exploration. Astronomy-gastronomy!
This video interview with Ashwin Vasavada, Deputy Project Scientist of the Mars Science Laboratory, is a nice overview of the what everybody's favorite currently operational Mars rover is looking for.
Here's a Google Map of the route, with stopping points. Big shuttle is big. Bigger than the streets that must accommodate her. Basically, the whole thing is like the ultimate slow-speed car chase, but with fewer live news choppers overhead.
