For me, the idea of a creation is not conceivable without invoking the necessity of design. One cannot be exposed to the law and order of the universe without concluding that there must be design and purpose behind it all.

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.

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?

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.

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!

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

I have learned to use the word 'impossible' with the greatest caution.
