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.

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.

You are not here merely to make a living. You are here in order to enable the world to live more amply, with greater vision, with a finer spirit of hope and achievement. You are here to enrich the world, and you impoverish yourself if you forget the errand.

Achievement is not always success, while reputed failure often is. It is honest endeavor, persistent effort to do the best possible under any and all circumstances.

Dissatisfaction with possession and achievement is one of the requisites to further achievement.

There is no personal achievement in being born beautiful.

Trust yourself. Create the kind of self that you will be happy to live with all your life. Make the most of yourself by fanning the tiny, inner sparks of possibility into flames of achievement.

My proudest achievement has been the success of the shows and artists I have been involved with, because they were made in Britain.

The salary of the chief executive of a large corporation is not a market award for achievement. It is frequently in the nature of a warm personal gesture by the individual to himself.

Immortality is not a gift, Immortality is an achievement; And only those who strive mightily Shall possess it.

My real achievement is my daughter and my three beautiful grandchildren.

Desire is the starting point of all achievement, not a hope, not a wish, but a keen pulsating desire which transcends everything.
