An outpost on the Earth’s moon has been a staple of science fiction since the 20th century. One of the earliest practical proposals was the U.S. Army’s 1959 design for a nuclear powered fortress, built to establish a military presence on the moon before the Soviet Union could do the same. A 1961 U.S. Air Force plan called for a 21-man underground lunar base, to be built by 1968. Current arguments for establishing a lunar colony include these potential uses: Resource mining (oxygen, rocket fuel, construction materials), energy (solar power, helium 3 mining for nuclear fusion), astronomical observations from the moon's far side, tourism.
