Project CORONA First American Spy Satellite Program
Project CORONA was not a vague legend. It was one of the most important declassified black programs in American intelligence history: a covert CIA and Air Force satellite system built to photograph denied Soviet and Chinese territory from orbit, return exposed film in small reentry capsules, and let aircraft snatch those capsules from the sky before the ocean swallowed them. Hidden publicly behind the Discoverer scientific-satellite cover story, CORONA failed again and again before Discoverer 14 finally returned usable photographs in August 1960. That single mission gave the United States more photographic coverage of Soviet territory than the entire U-2 program had previously produced, helped puncture exaggerated fears of a missile gap, and proved that space-based reconnaissance could replace the most dangerous overflights of the Cold War.
