France generates a significant part of its energy requirements from fission reactors and these have achieved a perfect safety record. We build ours all differently.

Rocket scientists agree that we have about reached the limit of our ability to travel in space using chemical rockets. To achieve anything near the speed of light we will need a new energy source and a new propellant. Nuclear fission is not an option.

History has repeatedly shown that when a new method or material becomes available, new uses for it arise.

Nuclear fusion of light elements like hydrogen or helium would permit approaching the speed of light. It seems very attractive to refuel your space ships where the fuel is.

This is no job for a UN committee. It needs the same kind of unwavering dedication and the kinds of people that got us the first nuclear submarine and the first man on the moon.

We need the kind of leadership exemplified by President Kennedy to just do it! But we must do it as good stewards, aggressively exerting control over the moon. We can best do this by going there.

The 20th Century was the century of Aviation and the century of Globalization. The next century will be the century of Space.
