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

We need to make science cool again.

Our future lies with today's kids and tomorrow's space exploration.

The stars don't look bigger, but they do look brighter.

All adventures, especially into new territory, are scary.

If we want scientists and engineers in the future, we should be cultivating the girls as much as the boys.

The space shuttle is a better and safer rocket than it was before the Challenger accident.

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

It's no secret that I've been reluctant to use my name for things.

Ever been to Disneyland? That was an E ticket!

So I decided on science when I was in college.

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

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

I liked math - that was my favourite subject - and I was very interested in astronomy and physical science.

I am watching the Earth. The visibility is good. I feel well and cheerful. The machine is functioning normally.

I feel fine. How about you?

If all those people are getting wet to welcome me, surely the least I can do is get wet too!

I see Earth! It is so beautiful.

I could have gone on flying through space forever.
