When you're in a spacecraft, you need to know what things you can touch and what things you shouldn't touch!

Space is not just going up and coming back down again. Space is getting into orbit and being there, living there, establishing a presence, a permanence.

Everyone who's been in space would, I'm sure, welcome the opportunity for a return to the exhilarating experiences there.

To me, money is a commodity that a person must have to function, not a goal in itself.

I feel we need to remind the world about the Apollo missions and that we can still do impossible things.

Nobody ever asks who was the seventh person on the Moon. The only thing they know is who's number one and who's number two. Does anybody know who the last man was?

I was the first Navy, Marine or Air Force person who had been an astronaut to return back to the Air Force. I had certain expectations about what would be a reasonable and desirable position to be assigned to after my years of service.
