What happens when you wring out a washcloth in space?

For hand towels, astronauts get those little vacuum-packed pucks that you kind of have to unravel into a towel. But what happens when you actually put the towels to use?

Two Nova Scotia high school students, Kendra Lemke and Meredith Faulkner, submitted this experiment to Canadian Space Agency and got to see astronaut Chris Hadfield actually test it out on the ISS. The results are seriously extraordinary and you need to see them.

Thanks, Dean!

Astronaut Chris Hadfield's otherworldly Earth landscapes, from space

"Venezuelan valley framed by misty clouds - mysterious, beautiful and surreal."—Chris Hadfield

As I've blogged before, Canadian Astronaut Chris Hadfield is currently living in space aboard the International Space Station (ISS) as Flight Engineer on Expedition 34 and he has been tweeting absolutely stunning photographs of Earth. Follow him on Twitter, for daily photo updates. Hadfield has captured some of the devastating floods hitting Australia this week, in images like the one below.

Fantastic tour of the International Space Station

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.

The effects of space travel on the human body (past and present)

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!

SpaceX Dragon spacecraft successfully attaches to ISS

For the second time in 2012, a SpaceX Dragon spacecraft has connected with the International Space Station. ISS expedition 33 crew members Akihiko Hoshide and Sunita Williams grappled Dragon and attached it to the station, completing a critical stage of the SpaceX CRS-1 cargo resupply mission.

Tomorrow: Student-designed experiments take flight on the International Space Station

The YouTube Space Lab competition gave teenagers around the world a chance to design a science experiment for the International Space Station. Tomorrow morning, starting at 9:30 Central, you can watch live while astronaut Sunita Williams conducts the two winning experiments, and see Bill Nye interview the experiments' creators—Amr Mohamed from Alexandria, Egypt; and Dorothy Chen and Sara Ma, from Troy, Michigan.

Astronauts fix the Space Station with a toothbrush

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.

Earth Illuminated: Dazzling ISS time-lapse photography, from NASA (video)

John Streeter, who is a television producer with NASA at Johnson Space Center in Houston, sends this cool video and tells Boing Boing:

It is all real, all shot from the International Space Station and all beautiful. It is time-lapse photography that showcases stars, cities at night, lightning storms and the aurora all from the vantage point of the space station. Also, there is a link at the end where you can visit, download and create your own videos if you wish.

The station is a remarkable engineering achievement and this is just a small side benefit of being in orbit. I hope you enjoy.

Artist’s rendition of Dragon spacecraft returning to Earth like a burning meteor. (SpaceX)

Space journalist Miles O'Brien spoke with CNN earlier this morning about the day's significance. On his blog, Miles writes:

With the shuttle fleet pickled, chocked and either in – or on their way to museums, Dragon is the only vehicle designed to haul cargo back to Earth in tact. Freighters from Russian, Europe and Japan are more like trash incinerators – as they do not have heat shields and parachutes designed to insure a safe landing.

Dragon is carrying just shy of 1400 pounds of cargo. More than it hauled up.

On board, about 300 pounds of crew preference items (lots of mementoes for friends and family), 200 pounds worth of scientific experiments, and nearly 800 pounds of station gear including a pump for the station urine recycling system (yes, they drink their own pee up there…).

Dragon will re-enter the atmosphere like a streaking meteor – as its ablative heat shield burns away - protecting the spacecraft from the searing heat.

Comet Lovejoy + Total Recall = awesome

Further evidence that the ability to remix scientific videos and images is awesome: Here's NASA's footage of the International Space Station rounding planet Earth to catch a glimpse of the comet Lovejoy, set to a piece of Jerry Goldsmith's score for the movie Total Recall. The result is breathtaking. Real life > than special effects.

Thank you, Avi Solomon!
