Space Race
The Space Race was a 20th-century competition between the United States and Soviet Union to achieve superior spaceflight capability, spanning from early rocket development through the first Moon landings and eventual cooperation.
1921 CE - 1924 CE
Soviet Gas Dynamics Laboratory Established
The Soviet military sanctioned the Gas Dynamics Laboratory, a small research laboratory to explore solid-fuel rockets, led by Nikolai Tikhomirov. This marked the beginning of organized Soviet rocket development efforts.
1925 CE - 1928 CE
First Soviet Solid Fuel Rocket Test
The first test-firing of a solid fuel rocket was carried out by the Soviet Gas Dynamics Laboratory. This represented an early milestone in Soviet rocket technology development.
1933 CE - 1936 CE
First Soviet Liquid-Fueled Rocket Launch
Soviet rocket pioneers Sergey Korolev, Friedrich Zander, Mikhail Tikhonravov and Leonid Dushkin launched GIRD-X, the first Soviet liquid-fueled rocket. This achievement demonstrated Soviet progress in advanced rocket technology.
Soviet Rocket Development Damaged by Great Purge
Joseph Stalin's Great Purge severely damaged Soviet rocket technology progress. Many scientists and engineers were imprisoned or executed, setting back the Soviet rocket program significantly.
1949 CE - 1952 CE
First Mammal in Space
Albert II, a rhesus monkey, became the first mammal in space when launched by the US on a sub-orbital flight. The monkey died on landing due to a parachute malfunction, but the mission demonstrated the possibility of sending living creatures to space.
Soviet Union Becomes Second Nuclear Power
The Soviet Union became the second nuclear power after the United States with the successful RDS-1 nuclear weapon test. This achievement intensified the Cold War arms race and provided the backdrop for the space competition.
Soviet R-1 Rocket Enters Service

Public Interest in Space Travel Sparked
Soviet rocketry engineer Mikhail Tikhonravov published 'Flight to the Moon' in the newspaper Pionerskaya pravda, describing a two-person interplanetary spaceship. This article sparked public interest in space travel and predicted space flight within 10-15 years.
1953 CE - 1956 CE
US Announces Intent to Launch Satellites
James C. Hagerty, President Eisenhower's press secretary, announced that the United States intended to launch 'small Earth circling satellites' as part of the International Geophysical Year. This announcement marked the official beginning of the Space Race.
Soviet Union Responds to US Satellite Announcement
At the Sixth Congress of the International Astronautical Federation in Copenhagen, Soviet scientist Leonid I. Sedov announced the Soviet Union's intention to launch a satellite 'in the near future.' This response escalated the space competition.
Soviet Space Commission Established
Sergei Korolev succeeded in convincing the Soviet Academy of Sciences to establish a commission dedicated to achieving the goal of launching a satellite into Earth orbit before the United States. This can be viewed as the de facto start date of the space race.
1957 CE - 1960 CE
R-7 ICBM First Successful Flight
The Soviet R-7 Semyorka flew 6,000 km and became the world's first intercontinental ballistic missile. This achievement gave the USSR the capability to strike US territory with nuclear weapons and provided the launch vehicle for future space missions.
