You know, piloting really isn't my hobby. And, it's probably not something I'd do in my spare time if I could do whatever I wanted to do. But, I'll tell you: if you've got to make a living, it's a great way to make a living!

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.

That's what Hubble can do for us. It can tell us whether the universe is expanding forever or if one day it's going to come back together.

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.

Now you're coming back to Earth, and things are getting more and more dynamic.

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