I inherited depression from my mother's side of the family. Her father committed suicide. She committed suicide the year before I went to the moon.

I feel we need to remind the world about the Apollo missions and that we can still do impossible things.

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.

Once you've been first, it cannot be done again. Not by you, not by anyone else.

Fighter pilots have ice in their veins. They don't have emotions. They think, anticipate. They know that fear and other concerns cloud your mind from what's going on and what you should be involved in.

A mind concerned about danger is a clouded mind. It's paralyzing.

At the core of the risk-free society is a self-indulgent failure of nerve.
