Because NASA's hip with the kids, dammit, they're using both YouTube and Twitter to let the public ask questions of astronaut Mark Polansky, commander of the International Space Station.

If you want to ask a question, just tape yourself asking it in 30 seconds or less, upload to YouTube, and then post the link on Polansky's Twitter. He'll be answering a few questions per week, so if you've got a question our fantastic guest blogger Leroy Chiao didn't get around to covering, this'll be a great way to get an answer.
