　　The first living creatures to travel in space were the dogs of the Soviet Unions space program.Beginning in 1951 dogs flew aboard sub－orbital flights to the height of 63 miles and higher.They helped to test the equipment that would later be used by humans.The first pair of dogs to fly, on July 22, 1951, were named Tsygan and Dezik.

　　Space dogs would make history on November 3, 1957.On this date, just one month after the historic launch of the world's first artificial satellite, Sputnik, the Soviet Union shocked the world again by launching Sputnik 2.This satellite contained the first living creature to travel in space, a dog named Laika.Laika was to have orbited for a week or more until her food and oxygen ran out.In fact, Laika lasted only hours in orbit before over heating in her capsule(太空舱) took her life.
