I Am Astronaut Chris Hadfield, Commander of Expedition 35.
Here is an introductory video to what I hope will be a great AMA.
My name is Chris Hadfield, and I am an astronaut for the Canadian Space Agency and Commander of the upcoming mission to the International Space Station. We will be launching at 6:12 p.m. Kazakh time on December 19th. You can watch it online here if you're so inclined.
I'm looking forward to all the questions. I will be in class doing launch prep. for the next hour, but thought I would start the thread early so people can get their questions in before the official 11:00 EST launch.
Here are links to more information about Expedition 35, my twitter and my facebook. I try to keep up to date with all comments and questions that go through the social media sites, so if I can't get to your question here, please don't hesitate to post it there.
Edit: Thanks for all the questions everyone! It is getting late here, so I am going to answer a few more and wrap it up. I greatly appreciate all the interest reddit has shown, and hope that you'll all log on and watch the launch on the 19th. Please be sure to follow my twitter or facebook if you have any more questions or comments you'd like to pass along in the future. Good night!
