Beginning in the late 1950s, space would become another dramatic arena for this competition, as each side sought to prove the superiority of its technology, its military firepower and–by extension–its political-economic system.The space race, the competition between the United States and the Soviet Union to explore outer space, was an integral part of the Cold War.
