Neil Armstrong

That's one small step for [a] man, one giant leap for mankind.

I think we're going to the moon because it's in the nature of the human being to face challenges. It's by the nature of his deep inner soul... we're required to do these things just as salmon swim upstream.

Research is creating new knowledge.

The important achievement of Apollo was demonstrating that humanity is not forever chained to this planet, and our destiny is out in the stars.

It's a great thing to be a part of. It's a great thing for our country.

I put my thumb up and I could hide the whole Earth behind my thumb. I felt like a little tiny speck in this vast universe.

I was elated, ecstatic, and extremely surprised that we were successful.

The one thing I regret is that I will never be able to go to the moon again.

I don't feel like I'm a hero.

It suddenly struck me that that tiny pea, pretty and blue, was the Earth. I put my thumb over it and I could make the Earth disappear. I didn't feel like a giant. I felt very, very small.

I think in terms of the future. I think in terms of what we can do, not what we can't do.

I wasn't chosen to be first. I was just chosen to command that flight. Circumstance put me in that particular role.

I don't believe in magic. I believe in science.

It was a surprise to me that we were able to bring back as much as we did.

The single most important factor in our success was that we were a team.

I was always a little uncomfortable with the 'first' part, because I was simply the one who was chosen to take that step.

It's a wonderful feeling to be able to look back and say, 'We did that.'

I think the one thing that we are not doing enough today is encouraging young people to take risks.

The unknowns were many, but our confidence was high.

It's a beginning. We have a lot more to do.
