Neil Armstrong

We did it not because it was easy, but because it was hard.

I think the one thing that I would say is that we truly weren't ready for what we saw.

The flight of Apollo 11 was a triumph of American ingenuity and determination.

It would be an untruth to say that I haven't done some good things in my life.

I was always a little bit of a tinkerer, always trying to figure out how things worked.

The most important thing we learned was that it is possible.

I don't feel like I'm a hero. I'm just a guy who went to the Moon.

It is a grand and glorious day to be an American.

The only way to reach the moon is to keep your eye on the stars.

I think we're going to have to find some way to live with the fact that we are not alone.

There are places in the universe that we can't even imagine.

I have been in space, and I have seen the Earth. It is a beautiful place.

The future of space exploration is not just about going to the Moon, it's about going to Mars and beyond.

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

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.

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

Knowledge is fundamental to all human achievement and progress. It is both the key and the quest that advances mankind. The search for knowledge is what brought men to the moon; but it took knowledge already acquired to make it possible to get there.

The single observation I would offer for your consideration is that some things are beyond your control. You can lose your health to illness or accident. You can lose your wealth to all manner of unpredictable sources. What are not easily stolen from you without your cooperation are your principles and your values. They are your most important possessions and, if carefully selected and nurtured, will well serve you and your fellow man.

Pilots take no special joy in walking: Pilots like flying. Pilots generally take pride in a good landing, not in getting out of the vehicle.

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