Space Race

Origins

The Space Race grew out of the missile competition that began when both superpowers seized Nazi Germany's V-2 rocket technology and personnel after World War II. When the United States announced plans to launch satellites for the International Geophysical Year in July 1955, the Soviet Union declared its own satellite program four days later, and Sergei Korolev's OKB-1 design bureau repurposed the military R-7 ICBM as a space launcher.

Course

The launch of Sputnik 1 on 4 October 1957 triggered the 'Sputnik crisis' in the West. The Soviet Union then passed nearly every early milestone first: Laika (1957), the Luna lunar probes (1959), Gagarin's crewed flight (1961), Tereshkova as the first woman in space (1963), and Leonov's spacewalk (1965). The United States, after Kennedy's 1961 Moon pledge, redirected its efforts toward a lunar landing, and on 20 July 1969 Neil Armstrong of Apollo 11 set foot on the Moon.

Who won

The conventional view holds that the United States won 'the big one,' but space historian Asif A. Siddiqi notes that the Soviet Union dominated nearly every smaller benchmark: first lunar impact, first photos of the Moon's far side, first soft landing, and first lunar orbit. The USSR also achieved unmatched success in Venus exploration, and the R-7 rocket family with the Soyuz spacecraft remains operational today. Rather than a single winner, the current assessment is that the two systems traced different trajectories through space, and the competition itself accelerated humanity's advance into space by decades.
