About Sputnik
The Soviet Union launched Sputnik 1, the first artificial satellite, on October 4, 1957. The polished sphere, 58 centimeters across, circled the Earth about every 96 minutes, sending radio beeps that listeners around the world could pick up.
Its launch started the space race between the Soviet Union and the United States.
