Yesterday, NASA and the Tech Museum in San Jose hooked up some Bay Area students with a couple of floating spacemen for a little Q&A. The event was part of Destination Station, NASA's "International Space Station Program national awareness campaign." Video from Bay Area News Group:
International Space Station Commander Dan Burbank and Flight Engineer Don Pettit answered the following queries, among others, live from orbit via video link:
Question: "Is going to the bathroom or taking a shower in space different than on earth?"
Answer: "We don't get to take a shower up here. We make due with towels, with soap and water, and we stay up here for six months... It's a little like being on a camping trip for a long time... It's really hard to manage all that water; those little droplets of water would just float around. We have a toilet that works great. We use air flow to help in the way that gravity works on earth."
