We knew it was going to be difficult to get to the moon. We didn't know how difficult.

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.

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

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.

I have the nicest life in the world.

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.
