The Soviet Union launches Sputnik 1, the world's first artificial satellite, igniting the Space Age and the US-Soviet Space Race.
On October 4, 1957, the Soviet Union successfully launched Sputnik 1, the world's first artificial satellite, into an elliptical low Earth orbit. The 58-centimeter, 83.6-kilogram polished metal sphere orbited the Earth every 96 minutes, transmitting radio pulses that could be detected by radio operators worldwide.
The launch stunned the world and had enormous political and scientific ramifications. In the United States, it triggered the "Sputnik crisis" — a period of public fear and anxiety about the perceived technological gap between America and the Soviet Union. The event directly led to the creation of NASA in 1958 and a massive increase in US science education funding.
Sputnik 1 burned up upon re-entering Earth's atmosphere on January 4, 1958, after three months in orbit. Its launch is widely regarded as the start of the Space Age and the beginning of the US-Soviet Space Race that would culminate in the Apollo 11 Moon landing twelve years later.
