The moon is bland in color. I call it shades of gray. You know, the only color we see is what we bring or the Earth, which is looking down upon us all the time. And to find orange soil on the moon was a surprise.

Curiosity is the essence of human existence.

OK, let's get this mother out of here.

I hold the world speed record downhill, in a Rover. I think it was 17 kilometers per hour, downhill.

I know the stars are my home. I learned about them, needed them for survival in terms of navigation. I know where I am when I look up at the sky. I know where I am when I look up at the Moon; it's not just some abstract romantic idea, it's something very real to me. See, I've expanded my home.

We don't have the capability today to put a human being in space of any kind, shape or form, which is absolutely, totally unacceptable when we got the greatest flying machine in the world sitting down at Kennedy in a garage there with nothing to do.

We went into darkness after being in daylight the whole time on the way to the Moon. And then we went into darkness. And we're in the shadow... of the Moon.
