Sputnik Declassified
On October 4, 1957, the Space Age dawned with the red hue of the Communist flag when the Soviet Union launched the first artificial satellite. Sputnik I stunned the world and spurred a surge in science education and innovation that changed our world forever. But was Sputnik I really a shock to America's leaders, and how close was the U.S. to getting into space first? NOVA draws on previously classified documents to tell the real story behind the opening chapter in the space race.
