 What makes the far side of the moon intolerable?
There is nothing like it on Earth, of course. 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. In the Moon's slight gravity, a man is really adjusted to existence when he has a well-developed case of agoraphobia. Otherwise, he was wholly matter-of-fact—certainly so for the far side of the Moon. 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. But there was a marked shortage of artists' materials on the Moon.
