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 slept just floating in the middle of the flight deck, the upper deck of the space shuttle.

But even in elementary school and junior high, I was very interested in space and in the space program.

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

You know, I go around the country a lot.

Ever been to Disneyland? That was definitely an E ticket!

That's something that is almost part of being human and I'm certain that will continue.
