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.

So most astronauts getting ready to lift off are excited and very anxious and worried about that explosion - because if something goes wrong in the first seconds of launch, there's not very much you can do.

Some astronauts sleep in sort of beds - compartments that you can open up and crawl into and then close up, almost like a little bedroom.

So most astronauts are astronauts for a couple of years before they are assigned to a flight.

NASA has to approve whatever we wear, so there are clothes to choose from, like space shorts - we wear those a lot - and NASA T-shirts.

It takes a couple of years just to get the background and knowledge that you need before you can go into detailed training for your mission.

I do a lot of running and hiking, and I also collect stamps - space stamps and Olympics stamps.
