Even an astronaut needs to wash her hair occasionally, and in a newly released video, astronaut Karen Nyberg demonstrates how it's done -- in space. Nyberg, 43, is currently the only female aboard the International Space Station, and the only member of the crew with hair that flows past her shoulders. In the zero gravity environment of the ISS, Nyberg's blond locks billow wildly around her head, even when her hair is pulled back in a ponytail. But when she lets her hair down to wash it, it sticks straight up above her head, troll-doll-style.

Everyone has to make time for a little home maintenance now and then, even when your home is orbiting 260 miles above the Earth. So bright and early Tuesday morning, Italian astronaut Luca Parmitano and NASA astronaut Chris Cassidy suited up for a six-hour-and-seven-minute spacewalk outside the International Space Station to knock a bunch of "to-dos" off their list. Tuesday's spacewalk was the fifth spacewalk of Cassidy's career, but the first for Parmitano, and the first for an Italian.

If astronaut Chris Hadfield can write as well as he can sing a David Bowie song, his upcoming book is going to be good. Hadfield has signed with Little, Brown to publish "An Astronaut's Guide to Life on Earth. " The book lands Oct. 29. During the five months Hadfield was commander of the International Space Station, he used social media to share his experiences, posting breathtaking photos and sharing videos. His personalized version of David Bowie's song "Space Oddity," which was posted online in May shortly before he returned to Earth, has been viewed more than 16 million times.

It's been two years since NASA's space shuttle program came to an end, but thousands of Americans still dream of becoming astronauts. Eight of them - four men and four women - were introduced Monday as NASA's astronaut candidate class for 2013. More than 6,300 people applied to become astronauts-in-training, NASA Administrator Charles Bolden said in a video announcement . That is the second-most applications the space agency has ever received, according to a NASA statement . The bios of the eight people selected will probably make you feel like a bit of a slacker.

Fifty years ago on June 16 - and only two years after the first man entered space - Soviet cosmonaut Valentina Tereshkova piloted the Vostok 6 through 48 laps around the Earth on a three-day solo mission under the call name Chaika (Seagull). At the age of 26, she'd spent more time in space than all the U.S. astronauts combined. Life magazine proclaimed, "She Orbits Over the Sex Barrier" and, in smaller type above that title, "a blue-eyed blonde with a new hairdo stars in a Russian space spectacular.

Astronauts heading to Mars would face exposure to a deluge of radiation, in some cases as much as NASA policy permits, according to new data from the Curiosity rover. The space agency limits astronauts to a 3% increased risk of fatal cancer. This translates to different levels of radiation exposure, depending on an astronaut's age and gender. But according to a paper published in Friday's edition of the journal Science, radiation exposure in a nonstop round-trip to Mars, which would take about a year, would ring in at about 662 millisieverts.

Streaming video by Ustream Three astronauts who recently returned to Earth after living aboard the International Space Station will answer questions from the public in a live Google Hangout on Thursday. The online chat starts at noon PDT, and you can watch it live right here. (The video stream above will switch to the hangout at noon.) If you've been wondering what it feels like to sweat through a heated reentry to Earth in the Soyuz capsule, or how foreboding a normal flight of stairs looks after months spent in zero gravity, now is your chance to ask three men with first-hand experience.

Space exploration and mass media always seem to travel in parallel orbits, like twin planets linked by an unseen tether. Now, a Twitter-happy Canadian who has been giving the Earth poetic glimpses of itself from the International Space Station is saying goodbye in a most peculiar way. Like a small metal moon, the ISS has orbited Earth for almost 13 years, which can make it easy to forget how cool it is. Cmdr. Chris Hadfield has been reminding us. "Arid fingers of sand-blasted rock look like they're barely holding on against the hot Saharan wind," Hadfield tweeted with one photo of Africa's largest desert. MORE: Chris Hadfield, coolest Canadian ever "Seven billion hearts, but I can see only one," he added, on Valentine's Day Feb. 14, tweeting a photo of an island formation resembling a heart . Although lower orbit is a good distance for beautiful color photography, it's a long way from home when tragedy strikes.

Astronauts replaced a leaking component on the International Space Station after a 5-hour, 30-minute spacewalk, NASA reported. Engineers Chris Cassidy and Tom Marshburn completed their spacewalk at 11:14 a.m. PDT Saturday, after gingerly gliding out to one of the station's trusses, where ammonia coolant had been seen leaking since Thursday. The coolant is used to control the temperature of one of eight solar arrays that power the station. The pair, who had worked in tandem during spacewalks twice before, removed the 260-pound pump controller box from the P6 truss and replaced it with a spare stowed nearby.

What happens when you wring a sopping wet washcloth out in space? Well, here's a hint: It's much more interesting than what happens here on Earth. This week, commander Chris Hadfield, an astronaut aboard the International Space Station, demonstrated what happens when you get a washcloth soaking in space and then wring it out. The experiment, called "Wring It Out" was designed by two 10th-graders in Nova Scotia. Kendra Lamke and Meredith Hatfield won a contest sponsored by the Canada Space Agency to come up with an experiment for an astronaut to perform in micro-gravity.
