All adventures, especially into new territory, are scary.

The food isn't too bad. It's very different from the food that the astronauts ate in the very early days of the space program.

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

The stars don't look bigger, but they do look brighter.

My background is in physics, so I was the mission specialist, who is sort of like the flight engineer on an airplane.

I do a lot of running and hiking, and I also collect stamps - space stamps and Olympics stamps.
