The Sputnik crisis was a period of public fear and anxiety in Western nations about the perceived technological gap between the United States and Soviet Union caused by the Soviets' launch of Sputnik 1, the world's first artificial satellite. The crisis was a significant event in the Cold War that triggered the creation of NASA and the Space Race between the two superpowers. The satellite was launched on October 4, 1957, from the Baikonur Cosmodrome. This created a crisis reaction in national newspapers such as The New York Times, which mentioned the satellite in 279 articles between October 6, 1957, and October 31, 1957.

Sputnik 1 was the first artificial Earth satellite. It was launched into an elliptical low Earth orbit by the Soviet Union on 4 October 1957 as part of the Soviet space program. It sent a radio signal back to Earth for three weeks before its three silver-zinc batteries became depleted. Aerodynamic drag caused it to fall back into the atmosphere on 4 January 1958. The world's first observation was made at the school observatory in Rodewisch (Saxony).
