On October 4, 1957, the world was stunned by a sound from space. The Soviet Union had launched Sputnik 1, the first artificial satellite. Designed under Chief Designer Sergei Korolev, it was a polished metal sphere, just 23 inches in diameter. Orbiting the Earth every 96 minutes, it broadcast a simple, steady 'beep-beep' signal that could be heard by amateur radio operators across the globe. For 21 days, until its batteries died, that signal was a constant reminder of Soviet achievement. More than a scientific first, Sputnik proved the Soviets possessed powerful rockets, capable of reaching anywhere on Earth. The Space Race had begun not with a speech, but with a beep heard around the world.
