For most of us, the Space Race is a familiar story. The Soviet Union shocked America when it launched history’s first satellite, Sputnik, in 1957, kicking off a race between the two superpowers. First came the race to get a man in space, one the Soviets won with Yuri Gagarin’s orbital flight in 1961. Then came the American-induced race to land a man on the Moon. From the Mercury through the Gemini and Apollo programs, NASA launched increasingly sophisticated missions as it worked out how to realize this goal. The Soviet Union, despite its early lead in space, couldn’t keep pace once NASA got going. The United States won the race to the Moon when Apollo 11 astronauts Neil Armstrong and Buzz Aldrin walked on the Sea of Tranquility in 1969.
