And then, when I thought about joining the Air Force, flying seemed like a natural extension of the motorcycling experience. You're going faster, higher. You're operating a machine that's a lot more powerful than you are.

So, I decided that whatever I was, wanted to do with my life, it would have to do, it would have to have something to do with the exploration and doing new things.

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.

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.

And, that's what I truly believe that we're doing when we're advancing scientific knowledge is we're someday making the world better. Not only for our children, but for all people after that.

I'm looking forward to coming back, back to Earth, the landing, the views.

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