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 that are not completely asinine 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
Edit: It appears that the questions received are taking a serious turn for the worse. Apparently, the anonymity of the internet is winning over the general desire for serious Q&A. As such, I'll be leaving the thread from here on out, and stop answering questions. If I didn't answer your question directly yet -- look around, because it may have been answered elsewhere (I had been informing people when their question had already been answered, but they got very rude very quickly so I quit), and if not don't be afraid to ask on twitter or facebook. That way, he'll be able to give you a bit more face time. Thanks to all who took it seriously and participated. For the most part, it was an enriching and enjoyable experience.
FYI: AMAs must reach a minimum karma score of 100 before it's considered for processing
