I felt very honored, and I knew that people would be watching very closely, and I felt it was very, very important that I do a good job.

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

Different astronauts sleep in different ways.

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.

I liked math - that was my favorite subject - and I was very interested in astronomy and in physical science.

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.

Anything from making a mistake on an experiment that would ruin some scientist on earth's experiment - career, potentially - to doing something wrong with the satellite that a country was depending on for its communications, to making some mistake that could actually cost you and the crew either a mission or your lives. So there is a lot of pressure that's put on every astronaut to just make sure that he or she understands exactly what to do, exactly when to do it, and is trained and prepared to carry it out.
