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.

I don't go through life verbalizing what I feel.

As time goes by, I'm increasingly impressed by how very special and timely it was that we got the degree of national commitment needed to put people on the Moon. For the first time, this nation was united in trying to develop an interplanetary capability. We've been trying to repeat that situation ever since.

If we can conquer space, we can conquer childhood hunger.

Unfortunately, pioneers will always pave the way with sacrifices.

The best way to study Mars is with two hands, eyes and ears of a geologist, first at a moon orbiting Mars... and then on the surface.

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.
