The Space Race was the competition between the United States and the Soviet Union roughly from 1957 to 1975, involving their efforts to explore space with satellites and to eventually land a human on the Moon and return him to Earth. Although its roots lie in early rocket technology and in the international tensions following World War II, the Space Race effectively began with the Soviet launch of Sputnik in 1957. The term was coined as an analogy to the arms race. The Space Race became an important part of the cultural and technological rivalry between the USSR and the U.S. during the Cold War. Space technology was a particularly important arena in this conflict, both because of its military applications and due to the psychological benefit of raising morale. The space race launched a concerted effort in the United States to improve technical education.
