One day soon, man is going to be able to harness incredible energy --
maybe even the atom. Energy that could ultimately hurl men to other
worlds in some sort of spaceship. And the men that reach out into space
will find ways to feed the hungry millions of the world, and to cure
their diseases. They'll be able to find a way to give each man hope
and a common future. And those are the days worth living for.
