There is beauty in space, and it is orderly. There is no weather, and there is regularity. It is predictable. Just look at our little Explorer; you can set your clock by it-literally; it is more accurate than your clock. Everything in space obeys the laws of physics. If you know these laws, and obey them, space will treat you kindly.

Man is not made for space. But with the help of biologists and medical doctors, he can be prepared and accommodated.

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.

The greatest gain from space travel consists in the extension of our knowledge. In a hundred years this newly won knowledge will pay huge and unexpected dividends.

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.

There is just one thing I can promise you about the outer-space program - your tax-dollar will go further.

In this modern world of ours many people seem to think that science has somehow made such religious ideas as immortality untimely or old fashioned. I think science has a real surprise for the skeptics. Science, for instance, tells us that nothing in nature, not even the tiniest particle, can disappear without a trace. Nature does not know extinction. All it knows is transformation. If God applies this fundamental principle to the most minute and insignificant parts of His universe, doesn't it make sense to assume that He applies it to the masterpiece of His creation, the human soul?
