I suggest taking the high road and have a little sence of humour and let things roll off your back. I think that's very important.

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.

The view of Earth is spectacular.

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.

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

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.

Well, we spend an awful lot of our time working and doing experiments. It's very busy up on the shuttle.
