This book covers the topic of Manufacturing in Space, which is not that far away, and has actually been done on a small scale for many years. With permanent manufacturing facilities in space, near to lunar or asteroid resources, we will be able to fabricate facilities from local material, and extract rocket fuel. All of this can replace what we now need very large rockets up from Earth's “gravity well.” We can build the next generation stations and spacecraft in situ, in orbit. There are some major advantages to this, as fewer parts need to be lifted up to orbit. Spin-off company's, providing logistics services, will be necessary. Space will be evolving as a frontier outpost. We have experience with those. But, space is a harsh environment, harsher than the Klondike during the gold rush. Yet, the gold rush happened.
