In 1971, the planet Mars will attract considerable attention, from laymen and from astronomers. For, this is the year in which Mars reaches its minimum distance from the Earth, some 35 million miles on August 10. No doubt, the press will publish a full quota of stories about canals, life on Mars, and whether or not the two moons of Mars are, in fact, satellites put into orbit by a long vanished race. There will invariably be the usual rash of flying saucer tales as is customary in years of close approach.
