 What do the colony inhabitants share?
The shack and the job he filled were located in the medieval notion of the physical appearance of hell. There is nothing like it on Earth, of course. They found the reason for the colony and the rocket landing field and the shack. There were air-tight bulkheads for safety, and a hydroponic garden to keep the air fresh, and all sorts of things to make life possible for men under if not on the Moon. All of which happened back on Earth and a long time ago. At the same time, liquid air from another tank evaporated to maintain the proper air pressure in the shack. The occupation made it absurdly easy to live on the surface of the far side of the Moon, whether anybody else could do it or not.
