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.

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.

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

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.

An Underground Cold War Network Was Found By NASA, But The Discovery Is Leading To Environmental Concerns . Back in April 2024, NASA made quite the discovery while flying over Gre

A NASA scientist uncovered a Cold War military base under ice in Greenland this April, as reported by NASA’s Earth Observatory on Monday. Several months ago, scientist Chad Greene was flying aboard a Gulfstream III with engineers in an effort to monitor a radar instrument on the Greenland Ice Sheet.
