NASA scientists found Camp Century, an abandoned Cold War military base, during a flight to map the Greenland Ice Sheet.

Scientists now have a clearer picture of Camp Century, an abandoned U.S. military base long hidden under the ice in Greenland, thanks to a NASA research team's good luck.

Nearly six decades later, however, experts can still catch glimpses of Camp Century—provided they have the proper underground radar equipment. And NASA Earth Observatory’s November 25, 2024, Image of the Day highlights just such an occasion.

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.

NASA has made a remarkable discovery while flying over the arctic ice in Greenland during an April 2024 survey. The radar instrument onboard NASA's Gulfstream III aircraft spotted an abandoned "city under the ice,
