Kepler Aria lyrics by Bruce Sterling
Kepler Aria:Punk Rock Star
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 the late 1950s, American scientists very publicly readied a crew of monkeys for a series of trips into Earth orbit and back. As far as the researchers knew, Project Discoverer was an actual, honest-to-Ike peaceful scientific program. Naturally, they were wrong about that. In reality, their work was part of an elaborate cover-up masking a spy satellite program

Chris Hadfield will be doing his first live Reddit AMA
(ask me anything) Sunday, February 17 at 9:00 GMT/UTC (4 pm ET). The Canadian astronaut and current commander of the International Space Station will answer all your questions about life in space, and whatever else you care to ask. Recently, Hadfield spoke with
fellow Canadian and space-lover William Shatner; their conversation is above.
Living on Mars time is making Katie Worth fat.
The journalist is attempting to live, on Earth, as if she's operating in a Martian time zone and blogging about the experience for Scientific American. On the 15th day of her experiment, she writes about how Mars time has changed her eating habits ... and made her drinking habits a whole lot sketchier-sounding.
Marc Fries, a research associate in the Smithsonian’s National Museum of Natural History and senior scientist at the Planetary Science Institute in Tucson, is doing a Reddit AMA to answer questions about meteorites. There's a briefQ&A on the Smithsonian Science website with Fries, too.
And while you're at it, check out this video with Smithsonian meteorite experts Cari Corrigan and Linda Welzenbach: a look inside the Smithsonian's new Antarctic meteorite storage facility in Suitland, MD., where all Antarctic meteorites in the national collection are kept under close security and tight airlocks.
A meteor has exploded over
, a remote part of Russia 150km north of Kazahstan. The meteor's descent was captured by many video cameras (largely the ubiquitous Russian dashboard cams, it seems). There are no reports of deaths, but apparently there are now 400 reported injuries. At least one large building, a zinc factory, had its roof demolished by the explosion.
A witness in Chelyabinsk reported hearing a huge blast early in the morning and feeling a shockwave in a 19-storey building in the town centre.
The sounds of car alarms and breaking windows could be heard in the area, the witness said, and mobile phones were working intermittently. "Preliminary indications are that it was a meteorite rain," an emergency official told RIA-Novosti. "We have information about a blast at 10,000-metre altitude. It is being verified."
"I was driving to work, it was quite dark, but it suddenly became as
bright as if it was day," said Viktor Prokofiev, a 36-year-old resident of
Yekaterinburg in the Urals mountains.
"I felt like I was blinded by headlights," he told Reuters.

What would happen if scientists suddenly stumbled upon a message from outer space? There's not actually a formal plan. No international body has ever decided whether we reply or not, and, if so, how we do it and what we say. But in 1967, we did get a dry run at a close encounter and, in the process, worked out a system of how confirm and report an alien communication that's still used today. Technology review has the story.

Members of the Barenaked Ladies performed their song 'I.S.S. (Is Somebody Singing)' over a video-link with Chris Hadfield, who is on the International Space Station:
Watch the video above as astronaut Chris Hadfield, from aboard the International Space Station, performs "I.S.S. (Is Somebody Singing)" with Ed Robertson, the rest of the Barenaked Ladies and the Wexford Gleeks from Wexford Collegiate School for the Arts, who were all at the CBC studios in Toronto.
The song, which was written by Hadfield and Robertson in partnership with Music Monday, CBC Music and the Canadian Space Agency, explores what it's like to look down on the Earth from outer space. It will also be the official song for the 2013 edition of Music Monday, which takes place on May 6.

12-year-old Lauren Rojas and her dad, Rod, built a balloon-lofted Hello Kitty space-capsule for her science fair project in Antioch, CA, and launched it 17 miles above the Earth's surface, recording its journey with video cameras and various sensors. The video is spectacular, especially the moments right before and right after the balloon burst and the parachutes deployed.
“We spent about one month planning and executing it,” he said. “We used a company called High Altitude Science in Colorado to get the equipment, the weather balloon and flight computer.”
Lauren and her father mounted small video cameras on their rocket-shaped gondola to record Hello Kitty’s journey. The balloon reached an altitude of 93,625 feet (17.73 miles), Rojas said. There, the air was so thin that the balloon burst, sending Hello Kitty from the sky. It landed in a tree 47 miles from the launch site, according to Rojas.

The European Space Agency is contemplating 3D printed moon-bases:
By using the Moon’s loose rocks (regolith) as a base for concrete, robots based on Monolite’s D-Shape 3-D printer will be able to build up a structure that uses as many local materials as possible. The idea is that with a shell made of moon rocks to act as a shield against micro-meteors and similar hazards, the living quarters for moon colonists could be inflatable envelopes protected by these shells.
3-D printing concrete in a vacuum is very, very different from printing it on earth. The teams have been experimenting with simulated moon rock material in vacuum chambers to find methods of construction that work. The problem being that concrete relies on applying liquids and unprotected liquids boil away when there’s no atmosphere. They discovered that by inserting the 3-D printer’s nozzle underneath the regolith, capillary forces kept enough liquid in place long enough to set properly.
This is also the premise of a novella I'm writing for Neal Stephenson/Arizona State University's Heiroglyphyics project. Nice to see reality clipping along!

Artist Philip J Bond created a set of illustrations depicting the women who've been to space. They're beautiful and full of personality and style, and really do justice to their subjects. I just showed these to my five year old daughter, and she was as entranced as I was.
Working for months at a time just penciling a comic book I started these portraits to get a bit of inking and colouring out of my system. I shouldn't say 'portraits', I'm not going for much of a likeness. Usually I'll glance at a couple of photographs and then go off and draw a vague impression. Margaret Seddon is blonde, Judith Resnik is a bit barmy looking, that sort of thing.
RealAbsurdity's "Modular Snap-Fit Airship" on Thingiverse is a 3D-printable toy whose parts can interchangeably form part of a Saturn V rocket. More snap-fit vehicles are planned.
This is a fully modular snap-fit (no glue required) model of an Airship. It is the vanilla base for a series of absurd mashups that currently includes a Trireme and a Saturn V rocket. Designed for 3D print, it comes in two flavors: solid and shell.

Caleb sends us an article, "Wherein I present the results of and detail the technical feats needed to stitch together imagery from six cameras into interactive fully spherical imagery and video taken from a balloon sent up to nearly 100,000 feet. (*phew*)"
There are some other factors that come into play with panorama stitching. You want to avoid placing control points on objects that move between images taken. Typical panoramas are done with one camera being rotated after each photo is taken. Objects that move between photos taken that have control points on them will severely hinder the stitching process.
You also want to avoid placing control points on objects at largely different distances from the lens. Don’t mix control points between objects a couple feet away and a hundred feet away as the optimizer won’t be able to make them fit to one transform. I’m able to mostly ignore this issue at very high altitudes as everything is so far away that the difference between the closer and the further objects is so slight that it doesn’t do much to negatively impact the optimization. Of course, that means I don’t allow any control points to be placed on anything attached to the camera payload, including the parachute and the balloon.
In order to place control points you have to have common features. That’s why you need the overlap between images. The more overlap the better the result. In the sample images above we have one image, the fourth, that isn’t able to be connected to any of the others. And it’s not because there’s no overlap. There are three issues with the fourth image that presents us from finding control points in it.
Operation StratoSphere – Conclusion
"Punk Voyager" is this week's story on the Escape Pod podcast, and it is fucking amazing. It's Shaenon Garrity story about punks at the twilight of the 1970s who are drunkenly outraged to discover that the Voyager probe has been launched with classical music records for aliens. They build their own Voyager probe out of garbage, razor-blades, beer cans and a surfboard some douchebag left on the beach, filled with all the most important human artifacts that they can find in their van. They forget about it as the 80s roar in, and then the aliens come to Earth and cockpunch Ronald Reagan.
Punk Voyager was built by punks. They made it from beer cans, razors, safety pins, and a surfboard some D-bag had left on the beach. Also plutonium. Where did they get plutonium? Around. Fuck you.
The punks who built Punk Voyager were Johnny Bonesaw, Johnny Razor, Mexican Johnny D-bag, Red Viscera, and some other guys. No, asshole, nobody remembers what other guys. They were Fucking wasted, these punks. They’d been drinking on the San Diego beach all day and night, talking about making a run to Tijuana and then forgetting and punching each other. They’d built a fire on the beach, and all night the fire went up and went down while the punks threw beer cans at the seagulls.
Forget the shit I just said, it wasn’t the punks who did it. They were Fucking punks. The hell they know about astro-engineering? Truth is that Punk Voyager was the strung-out masterpiece of Mexican Johnny D-bag’s girlfriend, Lacuna, who had a doctorate in structural engineering. Before she burned out and ran for the coast, Lacuna was named Alice McGuire and built secret nuclear submarines for a government contractor in Ohio. It sucked. But that was where she got the skills to construct an unmanned deep-space probe. Same principle, right? Keep the radiation in and the water out. Or the vacuum of space, whatever, it’s all the same shit to an engineer.
Fuck that, it wasn’t really Lacuna’s baby. It wasn’t her idea. The idea was Red’s.
“Fucking space,” he said that fateful night. He was lying on his back looking up at space, is why he said it.
“Hell yeah,” said Johnny Bonesaw.
It is definitely now the future.
A new venture is joining the effort to extract mineral resources on asteroids. The announcement of plans by Deep Space Industries to exploit the rare metals present in the space rocks turns asteroid mining into a two-horse race. The other venture, Planetary Resources, went public with its proposals last year.

Sunita Williams was in charge of the International Space Station for six months. On her last day in space, she made this 25-minute video — a much more in-depth tour of the ISS than I've personally ever seen before. This is the first time I've actually been able to get a sense of the whole interior layout of the ISS, rather than just seeing one place and then another with no understanding of how they connect. What's more, you really get a sense of the unearthly weirdness of moving through this space where walls are never just walls and "up" and "down" are essentially meaningless.
The video includes a detailed (but safe for work) demonstration of how to use the ISS bathroom; a behind-the-scenes peek of the pantry (with separate pantries for Russian and Japanese food); a visit to the Soyuz craft waiting to take Williams home; and the vertigo-inducing horror pod where all the really great pictures of Earth get taken.
Money quote: "I haven't sat down for 6 months now."
Also, for some reason, it bothers me that she refers to the "left" and "right" side of the Space Station, instead of port and starboard.
I've carried a Fisher Space Pen Bullet on and off since I was a kid. ("Write underwater and upside down!") I usually lose them in a matter of weeks, but while I can manage to hold on to one I do appreciate its minimalist design, small size, and great "fiddleability." Of course, the Space Pen is surrounded by some epic marketing and myth. Did NASA really invest millions to develop a perfect pen for astronauts? No, apparently, Fisher had developed the pen technology and later brought it to NASA. Following two years of testing, the space agency bought 400 of the pens at a 40 percent discount. And on October 11, 1968, Apollo 7 astronauts carried Fisher Space Pens, model AG7, into orbit.
