That's a very disappointing handle that people put on me.

People try to typecast astronauts as heroic and superhuman. We're only human beings.

What I remember perhaps most is starting up that ladder and looking over my shoulder and looking at those footprints down there and realizing that they were really mine and that there weren't going to be any (more) for a long time to come.

Curiosity is the essence of human existence and exploration has been part of humankind for a long time. The exploration of space, like the exploration of life, if you will, is a risk. We've got to be willing to take it.

It was probably the greatest singular human endeavor, certainly in modern times, maybe in the history of all mankind.

I wish I could send you some. It's amazing stuff.
