The Sputnik Crisis was a period of public fear and anxiety about the perceived technological gap between the United States and Soviet Union caused by the successful launch of Sputnik 1, the world's first artificial satellite. The crisis was a key event in the early Cold War that triggered the creation of NASA and Space Race between the two superpowers. The satellite was launched on October 4, 1957 from the Baikonur Cosmodrome. The term was coined by then US PresidentDwight D. Eisenhower.
