Yeah, I wasn't chosen to be first. I was just chosen to command that flight. Circumstance put me in that particular role. That wasn't planned by anyone.

Research is creating new knowledge.

I believe that every human has a finite number of heartbeats. I don't intend to waste any of mine running around doing exercises.

Geologists have a saying - rocks remember.

Here men from the planet Earth first set foot upon the Moon. July 1969 AD. We came in peace for all mankind.

This is one small step for a man, one giant leap for mankind.

We had hundreds of thousands of people all dedicated to doing the perfect job, and I think they did about as well as anyone could ever have expected.

Well, I think we tried very hard not to be overconfident, because when you get overconfident, that's when something snaps up and bites you.

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

I fully expected that, by the end of the century, we would have achieved substantially more than we actually did.

The one thing I regret was that my work required an enormous amount of my time, and a lot of travel.

Yeah, I wasn't chosen to be first. I was just chosen to command that flight. Circumstance put me in that particular role. That wasn't planned by anyone.

The important achievement of Apollo was demonstrating that humanity is not forever chained to this planet and our visions go rather further than that and our opportunities are unlimited.

As a boy, because I was born and raised in Ohio, about 60 miles north of Dayton, the legends of the Wrights have been in my memories as long as I can remember.

I believe every human has a finite number of heartbeats. I don't intend to waste any of mine.

Mystery creates wonder and wonder is the basis of man's desire to understand.

If that's there, I believe that technology will probably step up to their part of it.

Houston, Tranquillity Base here. The Eagle has landed.

Pilots take no special joy in walking. Pilots like flying.

In much of society, research means to investigate something you do not know or understand.

Gliders, sail planes, they're wonderful flying machines. It's the closest you can come to being a bird.

It's a brilliant surface in that sunlight. The horizon seems quite close to you because the curvature is so much more pronounced than here on earth. It's an interesting place to be. I recommend it.

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.

Science has not yet mastered prophecy. We predict too much for the next year and yet far too little for the next 10.

It suddenly struck me that that tiny pea, pretty and blue, was the Earth. I put up my thumb and shut one eye, and my thumb blotted out the planet Earth. I didn't feel like a giant. I felt very, very small.

I guess we all like to be recognized not for one piece of fireworks, but for the ledger of our daily work.

The Eagle has landed.

I put up my thumb and it blotted out the planet Earth.

I am, and ever will be, a white socks, pocket protector, nerdy engineer.

People love conspiracy theories.

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

In flying, the probability of survival is inversely proportional to the angle of arrival.

Here men from the planet Earth first set foot upon the Moon July 1969, A.D. We came in peace for all mankind.

Geologists have a saying rocks remember.

NASA has been one of the most successful public investments in motivating students to do well and achieve all they can achieve. It's sad that we are turning the programme in a direction where it will reduce the amount of motivation and stimulation it provides to young people.

There can be no great accomplishment without risk.

The view of the moon that we've been having recently is really spectacular. It fills about three-quarters of the hatch window, and of course we can see the entire circumference even though part of it is in complete shadow and part of it is in earthshine. It's a view worth the price of the trip.

Mystery creates wonder and wonder is the basis of man’s desire to understand.

Consistency is found in that work whose whole and detail are suitable to the occasion. It arises from circumstance, custom, and nature.

I don't think I could ever do a network sitcom because the humor is often based on some trite circumstance. I don't want to be a part of a show where it's mostly about coming up with the jokes.

The circumstance is the incredible part, but I always knew in my heart that something was going to be out there, just for the world to notice me. It sounds so cocky, but it's happening.

Privacy under what circumstance? Privacy at home under what circumstances? You have more privacy if everyone's illiterate, but you wouldn't really call that privacy. That's ignorance.

We were trained to live by our wits, in any circumstance.

At the first general meeting of this Corporation in 1820, his Lordship presided; a circumstance, which may well be considered an era in the history of the Church of Upper Canada.

And I am also here to say that if something were to happen, we are prepared to respond swiftly, to respond effectively, and to respond strongly. That is our tradition as a country. And that is a tradition that we will uphold, regardless of any circumstance because this nation is one that is very, very strong and, indeed, extraordinarily resilient.

It always remains true that if we had been greater, circumstance would have been less strong against us.

If we were in a similar circumstance in the future I would want to make sure that our reporting was at least as diverse as it was during this most recent war.

Nothing splendid has ever been achieved except by those who dared believe that something inside them was superior to circumstance.
