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!'

I think everything depends on money.

But I'm the only one who can paint the moon, because I'm the only one who knows whether that's right or not.

The moon is very rugged.

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

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

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.
