50th Anniversary of Sputnik: Traveling Companion
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. A short month later, on November 3, the Soviet Union followed this success by launching a dog into orbit aboard Sputnik 2 .
