I've been asked about UFOs and I've said publicly I thought they were somebody else, some other civilization.

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

Prepare for the unknown, unexpected and inconceivable . . . after 50 years of flying I'm still learning every time I fly.

I do believe there is life in outer space. Mathematically, there has to be, and if you believe as I do that there is a creator of the universe, then how can we be so arrogant to believe he created life here and nowhere else?

Neil Armstrong was probably one of the most human guys I've ever known in my life.

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.

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.
