IAmAn Astronaut who has been to space twice and will be commanding the I.S.S. on Expedition 35. AMA.
Details: Well, I am technically the son of an astronaut, but as my dad doesn't have the time to hover around the thread as questions develop, I'll be moderating for him. As such, I'll be taking the questions and handing them over to him to answer, then relaying it back here. Alternatively, you can ask him a question on his facebook or twitter pages. He is really busy, but he's agreed to do this for redditors as long as they have patience with the speed of his answers.
Note: This is a continuation of a thread I made in the AMA subreddit. You can see the previous comments here: http://tinyurl.com/3zlxz5y
