The Space Race was a 20th-century competition between the United States and the Soviet Union to achieve superior spaceflight capability. Driven by Cold War tensions and the desire to demonstrate technological and ideological superiority, the contest began with the Soviet launch of Sputnik in 1957 and culminated in the Apollo 11 Moon landing in 1969. It produced some of humanity's greatest scientific and engineering achievements, including the first human in orbit, the first spacewalk, and ultimately crewed lunar exploration — all within a single decade.
