Meet the NASA Astronaut Class of 2013 —
More than 6000 people applied, eight were chosen. And, for the first time, NASA has an astronaut class with gender parity — four men, and four women. — Maggie •

I don't know if I can fully define human nature, but I'm pretty sure it includes a prurient and/or practical interest in how one uses the bathroom under strange circumstances. Thus, the various videos you've seen over the years explaining how astronauts use the toilet on board the Space Shuttle and the International Space Station. Until a recent visit to Seattle's Museum of Flight, however, I'd never seen how cosmonauts do their business — an issue with increasingly broad reach, now that Americans and other international space voyagers are being ferried into the heavens aboard Soyuz.
The Soyuz toilet does not look much like the ones on board the Shuttle or the ISS. Those are recognizably toilets, for one thing. The Soyuz sanitary unit is more akin to peeing into a soda bottle in the back seat of the family station wagon — if that soda bottle were hooked up to a vacuum cleaner.
This video — kindly shared with us by The Museum of Flight — was filmed in 2009 by NASA astronaut Michael Barratt. It features the urination demonstration talents of spaceflight adventurer Charles Simonyi and Russian cosmonaut Gennady Padalka. Please note that this video only demonstrates how the "part Number 1" works — and even that really only seems to apply to gentlemen cosmonauts. As best I can tell, women apparently just pee into something akin to a compact diaper or sanitary pad. (Fun!) As for "part Number 2", here is how it was described in a 2007 NASA publication written by James Lee Broyan, Jr.:
For fecal collection, a porous bag is placed in the receptacle. Once defecation is complete, the bag is removed, placed sequentially in three bags, and then placed in a wet trash compartment. Based on personal conversations with АСУ trainers, urine collection is acceptable but fecal use is avoided if at all possible with the crew using diet restrictions and preventive measures prior to flight.
• Read the 2007 NASA publication comparing different space toilet systems. Apparently, part Number 2 has also been used by female cosmonauts to dispose of menstrual waste.
• Read a description on the RuSpace site, which gives a little more detail on part Number 2.

Thanks to Ted Huetter at The Museum of Flight!
Valentina Tereshkova, first woman in space, launch date June 16, 1963.
A wonderful website: fuckyeahfemaleastronauts.tumblr.com [new expletive-free URL] womeninspace.tumblr.com.
Only 10% of people in space have been women, and on tumblr that seemed even less. so here it is for your inspiration. Fuck yeah! Female Astronauts!

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.

Space is full of radiation. It's impossible to escape. Imagine standing in the middle of a dust storm, with bits of gravel constantly swirling around you, whizzing by, pinging against your skin. That's what radiation is like in space. The problem is that, unlike a pebble or a speck of dirt, ionizing radiation doesn't bounce off human flesh. It goes right through, like a cannonball through the side of the building, leaving damage behind.
Last week, researchers at the University of Rochester Medical Center published a study that suggests long exposures to galactic cosmic radiation — like the kind astronauts might experience on a trip to Mars — could increase the risk of developing Alzheimer’s disease.
Reading stories about that paper made me curious. We've now been sending people into space for more than 50 years. We've been able to track a generation of astronauts as they aged and died and we're constantly monitoring the people who travel in space today. Research like what was done at the University of Rochester is conducted on lab animals, mice and rats. It's meant to help us prepare for the future. But what do we know about the past? How has radiation affected the people who have already been to space? How is it affecting the people who are there now?

It was forty years today (at 22:54:37 UT) that human beings left the moon for the last time. Commander Gene Cernan's last words as stood on the moon were lofty, rehearsed and memorized:
"As I take man's last step from the surface, back home for some time to come (but we believe not too long into the future), I'd like to just say what I believe history will record: That America's challenge of today has forged man's destiny of tomorrow. And, 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."
His real last words uttered on the moon, just before hitting the button that would launch the "Challenger" Lunar Module carrying him and Harrison "Jack" Schmitt back to the orbiting Command Module "America" were more apt for a card-carrying member of the "Right Stuff Club".
"Okay, Jack, let's get this mutha outta here," said Cernan.
Cernan's autobiography "The Last Man on the Moon" is a great read. Among the things you might find surprising: Cernan crashed a Bell B-13 (M*A*S*H) helicopter into still water at Cape Canaveral in January of 1971 nearly killing himself. Read the rest
Last week, an American and a Russian — Scott Kelly and Mikhail Kornienko — were selected to spend a year living continuously in space, aboard the International Space Station. Only four other people have done this before. All them were Russian, so Scott Kelly is going to break the American record for time spent in space.
The mission won't start until 2015, and it's part of a much longer term goal — sending people to Mars. We know that spending time in space does take a toll on the human body. For instance, hanging out without gravity means you aren't using your muscles, even the ones that you'd use to support your own weight on Earth. Without use, muscles deteriorate over time. Bone density also drops. Basically, after a few months in space, astronauts return to Earth as weak as little kittens. Which is, to say the least, a less than ideal situation for any future Mars explorers.
Having Kelly and Kornienko stay up for a year will give scientists more data on what happens to the human body in space, give them a chance to test out preventative treatments that could keep astronauts stronger, and allows them to see how the amount of time spent in space affects the amount of time it takes to physically recover from the trip. As an extra research bonus, Kelly is the identical twin brother of Mark Kelly, the astronaut married to former congresswoman Gabrielle Giffords. Which means that there will be a built-in control to compare Kelly to when he comes back from his mission.
In honor of that upcoming experiment, here's an old video that will give you an idea of what we knew (and didn't know) back at the dawn of the space age. Science in Action was a TV show produced by the California Academy of Sciences. In this 1956 episode, they explore the then-still-theoretical physiology of space travel ... with a special guest appearance by Chuck Yeager!

Hurry, hurry, this is your chance to own the Toshiba Satellite Pro that President Bill Clinton used to email John Glenn in space on November 6, 1998. Apparently, the laptop belonged to a member of Clinton's medical staff who helped the president send the email to orbit. The laptop is listed at $125,000. Wonder how much RAM is in it. "Bill Clinton computer -Presidential email on it, to John Glenn in space!"
When NASA's Sunita Williams and Japanese astronaut Akihiko Hoshide couldn't seem to get a bolt attached to the outside of the space station, ground crews came up with a clever solution: Fix the problem with a toothbrush. At Space.com, Denise Chow explains the details:
On Aug. 30, Williams and Hoshide completed a marathon spacewalk that lasted more than 8 hours, but the astronauts were thwarted by a stubborn bolt and were unable to finish connecting the so-called main bus switching unit (MBSU). The stuck bolt forced NASA to add [yesterday's] extra spacewalk.
But, following last week's unsuccessful attempt, flight controllers, engineers and veteran spacewalkers worked around the clock at NASA's Johnson Space Center in Houston to devise a solution to the problem. Using only the supplies available on the space station, the teams came up with creative new tools for Williams and Hoshide to use to install the MBSU.
One was a modified toothbrush that was used to lubricate the inside of the bolt's housing after debris and metal shavings from inside had been removed. Another improvised instrument included a cleaning tool that had been made from wires that were bent back to form a brush, explained Kieth Johnson, lead spacewalk director at the Johnson Space Center.
