NEIL ARMSTRONG

I'm substantially concerned about the policy directions of the space agency. We have a situation in the U.S. where the White House and Congress are at odds over what the future direction should be. They're sort of playing a game and NASA is the shuttlecock that they're hitting back and forth.

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

Houston, Tranquillity Base here. The Eagle has landed.

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 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 can honestly say - and it's a big surprise to me - that I have never had a dream about being on the moon.

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

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

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

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

I thought the attractions of being an astronaut were actually, not so much the Moon, but flying in a completely new medium.

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.

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.

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

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

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.

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.

All in all, for someone who was immersed in, fascinated by, and dedicated to flight, I was disappointed by the wrinkle in history that had brought me along one generation late. I had missed all the great times and adventures in flight.

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.

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.

Geologists have a saying - rocks remember.

People love conspiracy theories.

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

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