What would people do on a lunar base? In a condensed version of his book, The Exploration of Space, Arthur C. Clarke described how space workers establish pressurized, permanent colonies so they could mine the moon for mineral resources. Initial bases made of plastic material or reinforced plastic would resemble igloos. Since a lunar night is equivalent to 14 Earth days, settlers would eventually build an observatory used for studying astronomy under stronger seeing conditions. If inhabitants found frozen water in caves, they could electrify it to produce hydrogen and oxygen, which could in turn provide rocket fuel for spaceships stopping over on voyages to other planets.
