As a NASA science flight was flying over the Greenland ice sheet this spring, a surprise popped up on a specialty radar: a hidden Cold War city more than 100 feet beneath the ice.

As it turns out, this abandoned "secret city" was the site of a secret Cold War project known as Project Iceworm which called for the construction of 2,500 miles (4,023 km) of tunnels that could be used to nuclear intermediate range ballistic missiles (IRBMs) at the Soviet Union.

NASA's radar revealed Camp Century, a Cold War base under Greenland's ice. It provides data on ice sheet melting and rising sea levels.

NASA performed a scientific mission earlier this year, surveying Greenland's massive ice sheet to test the limits and capabilities of its Uninhabited Aerial Vehicle Synthetic Aperture

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.

A radar image taken by Nasa scientists while flying over Greenland has revealed an abandoned Cold War -era “city” under the ice. Scientists and engineers took the radar image in April 2024 as they flew over northern Greenland aboard Nasa’s Gulfstream III jet.

NASA scientists accidentally uncovered Camp Century, a hidden Cold War base under Greenland's ice, using advanced radar technology in April 2024. This discovery not only brings historical artifacts to light but also assists in ice sheet studies critical for understanding future sea level changes.

NASA scientists have discovered the former military base Camp Century in Greenland. The discovery was made during tests of a device used to study the interior of glaciers. Although the base's existence was no longer a secret,
