Explanation:
Sputnik means "traveling companion". Despite the innocuous
sounding name, the launch of the Earth's first "artificial moon",
Sputnik 1, by the Soviets on October 4, 1957
shocked the free world, setting 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 Soviets followed this success by
launching a dog into orbit aboard Sputnik 2.
