Research is creating new knowledge.

There can be no great accomplishment without risk.

I didn't feel like a giant. I felt very, very small.

History will remember the twentieth century for two technological developments: atomic energy and space flight.

The Moon surface is fine and powdery. I can kick it up loosely with my toe. It does adhere in fine layers like powdered charcoal to the sole and sides of my boots. I only go in a small fraction of an inch, maybe an eighth of an inch, but I can see the footprints of my boots and the treads in the fine sandy particles.

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

Every flying machine has its own unique characteristics, some good, some not so good. Pilots naturally fly the craft in such a manner as to take advantage of its good characteristics and avoid the areas where it is not so good.

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

Perhaps it won't matter, in the end, which country is the sower of the seed of exploration. The importance will be in the growth of the new plant of progress and in the fruits it will bear. These fruits will be a new breed of the human species, a human with new views, new vigor, new resiliency, and a new view of the human purpose. The plant: the tree of human destiny.

I guess because deejaying has become my job, I tend to listen to really horrible stuff on my spare time. If you heard my iPod you'd be like, what the hell?

Good luck, Mr. Gorsky!

For those who may ask what they can do to honor Neil, we have a simple request. Honor his example of service, accomplishment and modesty, and the next time you walk outside on a clear night and see the moon smiling down at you, think of Neil Armstrong and give him a wink.

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

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

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

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

It's different, but it's very pretty out here. I suppose they are going to make a big deal of all this.

There are people I'll always love to listen to, and I'm always ending up discovering new songs by them, which is crazy. Like Stevie Wonder.

It's a strange, eerie sensation to fly a lunar landing trajectory not difficult, but somewhat complex and unforgiving.

A picture does a great job, but it's not nearly like being there.
