I have been a bit of a risk-taker all my life.
There are lots of opportunities out there for women to work in these fields, ... Girls just need support, encouragement and mentoring to follow through with the sciences.
I do a lot of running and hiking, and I also collect stamps - space stamps and Olympics stamps.
One thing I probably share with everyone else in the astronaut office is composure.
We need to make science cool again.
Well, we spend an awful lot of our time working and doing experiments. It's very busy up on the shuttle.
