One thing I probably share with everyone else in the astronaut office is composure.

It's well known that many girls have a tendency to dumb down when they're in middle school.

All adventures, especially into new territory, are scary.

I would like to be remembered as someone who was not afraid to do what she wanted to do, and as someone who took risks along the way in order to achieve her goals.

I have been a bit of a risk-taker all my life.

Astronauts will remain the explorers, the pioneers-the first to go back to moon and on to Mars. But I think it's really important to make space space available to as many people as we can. It's going to be a while before we can launch people for less than $20 million a ticket. But that day is coming.

Different astronauts sleep in different ways.
