The Future of Life In the not-so-far distant future, humans will learn to use the resources and the real estate that are offered by other worlds in space. Examples that have been considered in depth are the use of space stations to provide solar power in amounts sufficient to solve the energy crisis on Earth, and mining the Moon, asteroids and even Jupiter to extract valuable minerals and materials that are in scarce supply on Earth. Terraforming Mars, Titan or other objects in our Solar system will provide temporary homes for humanity before taking the big leap. In the century now beginning, space cities will cease to be science fiction. These colonies will provide a home for many human generations, providing an opportunity to live on cheap energy without waste or energy or wars. Beyond that, we have to use our imagination.
