“When you're getting ready to launch into space, you're sitting on a big explosion waiting to happen. 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.”

“There might be very primitive life in our solar system — single-cell animals, that sort of thing. We may know the answer to that in five or ten years. There is very likely to be life in other solar systems, in planets around other stars. But we won't know about that for a long time.”

“It's easy to sleep floating around — it's very comfortable. But you have to be careful that you don't float into somebody or something!”

“When you're on Earth, if you go to the top of a mountain, the stars look much brighter than they do at sea level. And because the space shuttle is above Earth's atmosphere, it's like being on a very, very high mountain. So they look brighter, but not bigger.”
