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

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

What we will have attained when Neil Armstrong steps down upon the moon is a completely new step in the evolution of man.

Looking back, nothing seems so simple than a utopian vision realised.

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.

There are flying grandfathers. But I intend to be an orbiting grandfather.

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.
