I consider myself to be very fortunate in my career, my timing has worked out.

Well, for me it really wasn't a case of deciding to be an astronaut.

There's been a tremendous amount of work that's been done that you can't see in Columbia.

And, so I set my goals on astronaut because, as a military aviator, it was, I considered that to be about the peak of a flying career.

So, we have to get up and get pumped up for each day.

And, all these things need to be coordinated; so we all need to work together, have timers going and everything so we're all coordinated and get this piece of orchestration done.

Because when we're in space, my job is primarily getting us there and getting us back.
