NASA astronaut ready to answer your questions from space

Flying 220 miles above the Earth aboard the International Space Station, NASA astronaut Greg Chamitoff, KD5PKZ, will respond to your questions. Up until now, questions to be answered by astronauts were asked by students during ARISS (Amateur Radio on the International Space Station) school contacts via ham radio. Chamitoff's schedule will not allow him to answer many questions, but he will attempt to answer a few each week.
To submit your question, post it in the comment box on NASA’s website. Include your name, age and location. Questions will be transmitted to Greg from Mission Control each week and his answers to a few of them will be available at the same website: http://www.nasa.gov/ask. All questions will be moderated during normal business hours (eastern U.S. time), and even then it may be several hours before they are posted.
