As the centuries unfold, millions of artists will live on the moon and paint the moon and Mars as we go out into the universe.

It seems farther away now because there are no rockets getting there. Nobody is going.

Frequently on the lunar surface I said to myself, 'This is the Moon, that is the Earth. I'm really here, I'm really here!'

History has spurts and then is steady, and then maybe even backing up a step, and then forward again.

The moon is very rugged.

Test pilots have a litmus test for evaluating problems. When something goes wrong, they ask, "Is this thing still flying?" If the answer is yes, then there's no immediate danger, no need to overreact.

It's hard not to be excited when you're going to find a way to land on the moon.
