The moon I see now is the same moon I saw before. Except that before, when I looked at it, it was in anticipation of what it would be like when I got there. That's behind me now.

My favourite thing to do on this planet is to scuba dive.

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.

The way I see it, what is going to come out of the moon activities is a respect for U.S. leadership.

There's a historical milestone in the fact that our Apollo 11 landing on the moon took place a mere 66 years after the Wright Brothers' first flight.

My Sunday mornings are spent in a recovery meeting in Pacific Palisades.

When we set out to land people on the surface of Mars, I think we should as a nation, as a world, commit ourselves to supporting a growing settlement and colonization there. To visit a few times and then withdraw would be an unforgivable waste of resources.
