		Sputnik 1 (Спутник-1, Satellite 1) was the first artificial satellite to be put into orbit, on October 4, 1957.
		Coming at the height of the Cold War, the launching of Sputnik caught the West by surprise, and in the U.S. led to a wave of self-recriminations, the beginning of the space race, and a movement to reform science education.
		The Sputnik 1 spacecraft was launched from Baikonur Cosmodrome at Tyuratam (370 km southwest of the small town of Baikonur) in Kazakhstan, then part of the Soviet Union.

		Sputnik was seen as a challenge to the US technology, as well as evidence of Soviet missiles with intercontinental range.
		In view of the success of Sputnik and the failure of Vanguard, Von Braun's launch plan was given the go-ahead, and on January 31, 1958, it orbited the first successful US satellite, Explorer 1 (launch picture on right).
		Unlike the orbits of the Sputniks, that of Explorer 1 was quite elliptic, rising to altitudes above 2000 km.
