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 find it as difficult to understand a scientist who does not acknowledge the presence of a superior rationality behind the existence of the universe as it is to comprehend a theologian who would deny the advances of science.

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.

In this age of space flight, when we use the modern tools of science to advance into new regions of human activity, the Bible... remains in every way an up-to-date book. Our knowledge and use of the laws of nature that enable us to fly to the Moon also enable us to destroy our home planet with the atom bomb. Science itself does not address the question whether we should use the power at our disposal for good or for evil. The guidelines of what we ought to do are furnished in the moral law of God.

The first men who set out for Mars had better make sure they leave everything at home in apple-pie order. They won't get back to earth for more than two and a half years. The difficulties of a trip to mars are formidable. . . . What curious information will these first explorers carry back from Mars? Nobody knows-and its extremely doubtful that anyone now living will ever know. All that can be said with certainty today is this: the trip will be made, and will be made . . . someday.

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

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