I suppose the one quality in an astronaut more powerful than any other is curiosity. They have to get some place nobody's ever been.

Too many people, when they get old, think that they have to live by the calendar.

I think no matter where we go in space to me the important thing is not only getting there and getting back, but it's also doing research, because that opens up as a possibility with that new distance of travel in space.

I don't like the way the whole thing has developed. And I just hope that we develop our own transportation system, both spacecraft and new boosters, as soon as possible. I hate to think that we may be out there seven to ten years out and dependent on the Russians for our journey into space.

The moment of twilight is simply beautiful.

I was sold on flying as soon as I had a taste for it.

I am a stranger. I come in peace. Take me to your leader and there will be a massive reward for you in eternity.
