Space Settlement

spreading life throughout the solar system "I know that humans will colonize the solar system and one day go beyond." Mike Griffin, former NASA Administrator.

A billion years ago there was no life on land. In a phenomenal development, by 400 million years ago land life was well established. We are at the very beginning of a similar, perhaps even more important, development. Today Earth teems with life, but as far as we know, in the vast reaches of space there are only a handful of astronauts, a few plants and animals, and some bacteria and fungi; mostly on the International Space Station. We can change that. In the 1970's Princeton physicist Gerard O'Neill, with the help of NASA Ames Research Center and Stanford University, discovered that we can build gigantic spaceships, big enough to live in. These free-space settlements could be wonderful places to live; about the size of a California beach town and endowed with weightless recreation, fantastic views, freedom, elbow-room in spades, and great wealth. In time, we may see millions of free-space settlements in our solar system alone. Building them, particularly the first one, is a monumental challenge. If this sounds exciting, read on.
