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

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.

I believe in an immortal soul. Science has proved that nothing disintegrates into nothingness. Life and soul, therefore, cannot disintegrate into nothingness, and so are immortal.

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.

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.

Never go to a doctor whose office plants have died.

Medicine is the keystone of the arch of socialism.
