Astronaut Greg Chamitoff, aboard the International Space Station 220 miles above Earth, is taking your questions.
Post a video response to this video or visit http://www.nasa.gov/ask and submit a question there. Chamitoff's schedule will not allow him to answer many questions, but he will attempt to answer a few each week.
