I'm quite disappointed that I'm still the last man on the moon.

To become an astronaut, someone has to have a dream of his own to do something that he or she has always wanted to do, then commit himself to making that dream come true.

If the guidance failed or started to stray or went somewhere we didn't like or the ground didn't like, I could flip a switch, and I could control seven, over seven and a half million pounds of thrust with this handle and fly the thing to the Moon myself.

One of the most important things about the geology on the moon is your descriptions of what you see, comparing them to things that you've seen on Earth so that the geologists and the scientists on the ground would know what you're talking about; and then take pictures of them.

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

People try to typecast astronauts as heroic and superhuman. We're only human beings.

If you begin to think you're something you're not, you're looking in the wrong mirror.
