If you are one of the throngs of Twitter fans, NASA shuttle commander Mark Polansky, the commander of the shuttle mission scheduled to launch in June, will be answering questions from space using Twitter. Right now Polansky is sharing Tweets about training and the flight on Twitter.

Polansky will be the commander of shuttle flight STS-127 aboard the Endeavour. The mission is expected to leave the Earth on June 13th to deliver the final section of the Japanese laboratory module and to post tweets about the crews training.

Followers will be able to submit video questions via YouTube and tweet the link to Polansky's account at @Astro_127. One or two of the submitted questions will be answered each week from orbit.
