Our future lies with today's kids and tomorrow's space exploration.

The thing I'll remember most about the flight is that it was fun. In fact, I'm sure it was the most fun that I'll ever have in my life.

I've discovered that half the people would love to go into space and there's no need to explain it to them. The other half can't understand and I couldn't explain it to them. If someone doesn't know why, I can't explain it.

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

I don't have any nicknames.

Even though NASA tries to simulate launch, and we practice in simulators, it's not the same - it's not even close to the same.

I didn't really decide that I wanted to be an astronaut for sure until the end of college.
