One of the greatest adventures in the future of humanity will be to construct, work, and live in space based structures.

In this book we look at the history of ideas for living in space, proposed space colony designs, and technology.

The details of current life support technology on the International Space Station is reviewed, and what technologies will be required for development of large scale space colonies.

What other things in terms of financing and materials availability will be needed also.

Finally, we conclude with some recommendations to get us ready to build these colonies.
