High Frontier

In the near future, nanofacturing techniques will allow incredible new materials to be built atom by atom. But they can only be built in the zero-gravity and high-vacuum conditions in space. Various private and government enterprises race to establish a buckytube mechanosynthesis factory on a suitable carbonaceous asteroid. To do so, they accumulate tanks of water in orbiting fuel depots, to be used as rocket propellant. Also needed are remote-controlled robonauts to do the grunt work.

The key to success is water in LEO (low Earth orbit). At first, water will be expensively upported out of the deep gravity well of Earth. But for a third the fuel and energy, water can be supplied from Luna, the moons of Mars, or other nearby hydrated objects. Extracting resources at the work site is called In-Situ Resource Utilization (ISRU). Whoever develops ISRU technology able to glean water from space rather than Earth will gain the strategic high ground to make money through exoglobalization.

Now in its second edition. The second edition expansion (aka High Frontier Colonization) is now available for preorders with an expected publication in the summer of 2013. (this expansion is compatible with the 1st and 2nd editions).
