And, one thing I definitely enjoyed personally, from a selfish point of view, was exploration and going to places that I had never been to before and learning, you know, meeting the people and getting to know, new sights and sounds, etc.

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

I worked for some very good people who have helped me along the way and actually enabled me to have the opportunity to be selected to join the Astronaut Corps.

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 see it as one of my jobs to make sure that, it sounds ridiculous, but to make sure the folks are eating, make sure folks are getting enough fluids, make sure folks are, you know, comfortable in the orbiter.

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.

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.
