The atmosphere almost looks like an eggshell on an egg, it's so thin. We know that we don't have much air - we need to protect what we have.

Some people said, “we don't want to risk astronauts lives anymore, we need to stop doing this”. The astronauts don't feel that wayWe fly for our country, we fly for humanity, we fly for exploration, we fly for a variety of reasons, and we don't stop flying because we have accidents.

My daughter just thinks that all moms fly the Space Shuttle

I have no nerves, no emotion, no pressure.

Because of [Amelia Earhart], we had more women available to fly in the 1940's to help us get through World War II. And because of these women, women of my generation are able to look back and say, 'Hey, they did it. They even flew military airplanes, we can do it, too.'

I don't think of myself as being a woman and having anything to prove.

The vast majority of the shuttle program was a success. We learned so much about how a reusable spacecraft interacts with its environment, how it ages-and what to design next time.
