But why, some say, the moon? Why choose this as our goal? And they may as well ask why climb the highest mountain?

As we got further and further away, it [the Earth] diminished in size. Finally it shrank to the size of a marble, the most beautiful you can imagine. That beautiful, warm, living object looked so fragile, so delicate, that if you touched it with a finger it would crumble and fall apart. Seeing this has to change a man.

We want to explore. We’re curious people. Look back over history, people have put their lives at stake to go out and explore … We believe in what we’re doing. Now it’s time to go.

The regret on our side is, they used to say years ago, we are reading about you in science class. Now they say, we are reading about you in history class.

We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win.
