NASA has released images of a nuclear military base built 30 meters below the ice cap, whose existence had been completely forgotten. During a flyover in an autonomous aircraft, scientist Chad Greene detected an anomaly deep within the ice.

NASA scientists have found the remains of a U.S. military base buried 100 feet below the surface of the ice in Greenland. Camp Century, as it was called, was a Cold War-era satellite for the U.S. Army used as a front for a planned arsenal of nuclear missiles.
