Lunar Resources

The regolith on the Moon contains, among other things, a huge reservoir of oxygen to support human life. Other minerals included in lunar regolith are silicon, iron, calcium, aluminum, and magnesium. Accessing them requires an industrial presence on the Moon. Initially this will have to come from Earth, at substantial cost. Once this cost has been borne, oxygen and other raw materials will be available at the bottom of a much weaker gravity well than Earth’s. Manufacturing in space for use in space cuts cost dramatically
