The Millennial Project: Colonizing the Galaxy in Eight Easy Steps by Marshall T. Savage is a book (published in 1992 and reprinted in 1994 with an introduction by Arthur C. Clarke) in the field of exploratory engineering that gives a series of concrete stages the author believes will lead to interstellar colonization.

Many specific scientific and engineering details are presented, as are numerous issues involved in space colonization.

He draws heavily on the Fermi paradox (briefly stated as, "If there is intelligent life in space, why haven't we found it yet?")

In The Millennial Project, he calls for the creation of an international foundation to realize these goals.

The book has drawn some criticism in that while it is replete with details concerning OTEC construction and space colonization, it touches very little on the subject of how governments and societies will need to change to enact the Project.
