Having walked on the Moon, I know something about what we need to explore, really explore, in space.

Six out of seven times we landed successfully [on the Moon]. I wanted to be a part of that and I was a part of that, so my personal feeling is of great gratefulness for having somehow been in a position to have been given the opportunity to be on that first landing. That's a marvelous experience for a little kid that grew up in New Jersey. So I'm very thankful, and I asked the whole world to give thanks once we successfully landed.

It's been one of the greatest challenges that ever came along in my life; it was one of the more difficult things to do.

We should go boldly where man has not gone before. Fly by the comets, visit asteroids, visit the moon of Mars. There's a monolith there. A very unusual structure on this potato shaped object that goes around Mars once in seven hours. When people find out about that they're going to say 'Who put that there? Who put that there?' The universe put it there. If you choose, God put it there.

I came to dedicate my life to opening space to the average person and crafting designs for new spaceships that could take us far from home. But since Apollo ended, such travels were only in our collective memory.

We're number one on the runway.

I'm not in favor of just taking short-term isolated situations and depleting our resources to keep our climate just the way it is today.
