My parents must have done a great job. Anytime I wanted to pursue something that they weren't familiar with, that was not part of their lifestyle, they let me go ahead and do it.

Then during the mission itself, I used the space shuttle's robot arm to release a satellite into orbit.

We need to make science cool again.

One thing I probably share with everyone else in the astronaut office is composure.

I haven't written my memoirs or let the television movie be made about my life.

So most astronauts are astronauts for a couple of years before they are assigned to a flight.

You know, I go around the country a lot.
