This was a major event as it launched a race to space between the two super powers of this era, the United States and the USSR. (now the Russian Federation).
The image of the day by the NASA (APOD) is of course dedicated to this anniversary and several newspapers talked about it.
According to the NASA :
Sputnik means “traveling companion”. Despite the innocuous sounding name, the launch of planet Earth’s first artificial moon, Sputnik 1, by the Soviet Union on October 4, 1957, changed the world and set in motion events which resulted in the creation of NASA and the race to the Moon.
Sputnik 1 was a 184 pound, 22 inch diameter sphere with four whip antennas connected to battery powered transmitters. The transmitters broadcast a continuous “beeping” signal to an astounded earthbound audience for 23 days.
