“Man belongs wherever he wants to go – and he’ll do plenty well when he gets there.”

If we were to start today on an organized and well-supported space program I believe a practical passenger rocket can be built and tested within ten years.

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

I believe that the time has arrived for medical investigation of the problems of manned rocket flight, for it will not be the engineering problems but rather the limits of the human frame that will make the final decision as to whether manned space flight will eventually become a reality.

With our present knowledge, we can respond to the challenge of stellar space flight solely with intellectual concepts and purely hypothetical analysis. Hardware solutions are still entirely beyond our reach and far, far away.

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.

I only hope that we shall not wait to adopt the program until after our astronomers have reported a new and unsuspected asteroid moving across their fields of vision with menacing speed. At that point it will be too late!

One good test is worth a thousand expert opinions.

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.

If we continue at this leisurly pace, we will have to pass Russian customs when we land on the moon.

Basic research is what I am doing when I don’t know what I am doing.

Conquering the universe one has to solve two problems: gravity and red tape. We could have mastered gravity.

The rocket worked perfectly, except for landing on the wrong planet.

Our sun is one of a 100 billion stars in our galaxy. Our galaxy is one of billions of galaxies populating the universe. It would be the height of presumption to think that we are the only living thing in that enormous immensity.

A good engineer gets stale very fast if he doesn’t keep his hands dirty.

My experiences with science led me to God. They challenge science to prove the existence of God. But must we really light a candle to see the sun?

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.

The ability and inclination to use physical strength is no indication of bravery or tenacity to life. The greatest cowards are often the greatest bullies. Nothing is cheaper and more common than physical bravery.

He is a great leader by example. Someone whom I have always admired for his ability to remain balanced and have the sense of equanimity about his captaincy.

I always was like, “Yo, I’m here, I might as well get what I could take.”

I did my best. I guess my best wasn’t good enough.

I could put everything I got in the bank on my abilities and skill and will, and what I’m capable of doing in the ring.

I just have an inability to lie.

When I step in the ring, I bring everything I have.

I was an okay singer. I was an okay dancer. But acting? Never could do it.
