In _May 1959_, the United States sent a pair of monkeys, Able and Baker, into space on a Jupiter missile. They were the first living creatures to be successfully recovered after a trip into space. Although Able died in June 1959, monkey Baker survived until _1984__. Later in _1959_and in early 1960 there were further experiments involving a pair of monkeys named Sam and Miss Sam. Soviet scientists decided against using monkeys for test flights. Their scientific research - published in September 1958 - suggested the monkeys would have to be anaesthetized and the anaesthetic would interfere with test results. They had already launched a dog, Laika, into space in__November 1957_. At the time, Russian scientists claimed the dog had survived a week in orbit but later reports show it died shortly after take-off from overheating and panic. But it was the Russians who won the race to launch the first man into space. Major Yuri Alexeyevich Gagarin orbited the earth for nearly two hours on _12 April 1961_.
