NASA flew over Greenland in 2024 to map the depth of the ice sheet and layers of bedrock below it.
The images revealed a new view of Camp Century , a Cold War-era U.S. military base.
Camp Century was the site of a secret Cold War project known as Project Iceworm .
The base was abandoned in 1967 due to the costs and challenges of keeping the tunnels from collapsing in the ever-shifting ice sheet.
