You can’t have a baby in one month by getting nine women pregnant.

Everybody knows what the moon is, everybody knows what this decade is, and everybody can tell a live astronaut who returned from the moon from one who didn’t.

I’m convinced that before the year 2000 is over, the first child will have been born on the moon.

I have learned to use the world ‘impossible’ with the greatest caution.

Nature does not know extinction; all it knows is transformation. Everything science has taught me, and continues to teach me, strengthens my belief in the continuity of our spiritual existence after death.

By the year 2000 we will undoubtedly have a sizable operation on the Moon, we will have achieved a manned Mars landing and it’s entirely possible we will have flown with men to the outer planets.

My friends they were dancing here in the streets of Huntsville when our first satellite orbited the Earth. They were dancing again when the first Americans landed on the Moon. I’d like to ask you, don’t hang up your dancing slippers.

Don’t tell me that man doesn’t belong out there. Man belongs wherever he wants to go – and he’ll do plenty well when he gets there.

Get me a broom. I’ll sweep my own office.

All one can really leave one’s children is what’s inside their heads. Education, in other words, and not earthly possessions, is the ultimate legacy, the only thing that cannot be taken away.
