Sputnik

Sputnik:

On October 4, 1957 the Soviet Union successfully launched Sputnik. Sputnik is the the world's first Earth-orbiting artificial satellite. The Sputnik traveled at a speed of 18,000 miles per hour and circled the globe every 96 minutes. When it was launched, it also launched a large sense of paranoia in the U.S. because it was a start of many advances in war for the Soviet Union. On January 31, 1958 America launched it's first satelline into space.
