Bootstrap Resources in Space

Since it is not practical to lift from Earth into space all of the construction materials necessary to build living structures (habitats), they must be extracted/mined from sources already existing in space.

Stepping Stones: Economic Analysis of Space Transportation Supplied From NEO Resources

The Stepping Stones economic analysis of space transportation supplied from near-Earth object (NEO) resources demonstrates the potential to break the tyranny of increasing space transportation costs created by dependence on Earth-based resources, particularly propellant. The increasing challenges of space exploration, particularly by humans, rapidly become unaffordable if only Earthbased resources are available. By using Asteroid-Provided In-Situ Supplies (Apis™) spacecraft to extract resources from NEOs and the creation of a space-based transportation infrastructure, including a crewed lunar outpost in an energetically advantageous lunar orbit for storage and propellant processing along with reusable spacecraft for transport, these resources can be utilized to
support crewed lunar surface exploration, crewed NEO exploration, crewed Mars missions, and even space tourism at less than 25% of the cost otherwise required (~90B$ vs ~390B$ over 20+ years). This analysis further suggests that with relatively modest initial government investment, a business case can be developed for a profitable industry in space resources.
