Soviet Union
On October 4, 1957, the world's first artificial satellite, Sputnik, was launched, marking the beginning of the "Space Age" in the Soviet Union. Moscow time from the launch base in the Republic of Kazakhstan.
Sputnik is 22 inches in diameter, weighs 184 pounds, and orbits the Earth once every 1 hour and 36 minutes. Its elliptical orbit, traveling at 18,000 mph, was 584 miles at the apogee (farthest point) and 143 miles at the perigee (closest point). Sputnik was visible through binoculars before sunrise or after sunset and sent back to Earth a radio signal strong enough for amateur radio operators to pick up. Americans who accessed such devices were in awe of seeing Soviet spacecraft flying overhead several times a day. In January 1958, Sputnik's orbit deteriorated as expected, and the spacecraft burned out in the atmosphere.
