I had both male and female heroes.

I suggest taking the high road and have a little sence of humour and let things roll off your back. I think that's very important.

The view of earth is absolutely spectacular, and the feeling of looking back and seeing your planet as a planet is just an amazing feeling. It's a totally different perspective, and it makes you appreciate, actually, how fragile our existence is.

When you can feel that close to something you're used to seeing from this great distance, well, it changes a person.

I was always very interested in science, and I knew that for me, science was a better long-term career than tennis.

Once you are assigned to a flight, the whole crew is assigned at the same time, and then that crew trains together for a whole year to prepare for that flight.

The best advice I can give anybody is to try to understand who you are and what you want to do, and don't be afraid to go down that road and do whatever it takes and work as hard as you have to work to achieve that.
