The “Space Race” was a Cold War competition in space and rocketry between the US and USSR spanning from 1955 to the mid-1970s. Milestones include Sputnik (1957, USSR), Gagarin’s first human spaceflight (1961, USSR), and Apollo 11’s first crewed Moon landing (1969, USA).
While 1969 is often treated as a symbolic inflection point, US lunar victory was followed by Apollo mission cancellations, falling NASA budget share, and a shift toward détente. Competition continued (e.g., USSR’s Luna sample returns and Salyut space stations; US Skylab), culminating in the 1975 Apollo–Soyuz Test Project.
