"We were looking for the bed of the ice and out pops Camp Century," NASA scientist Chad Greene said after spotting the secret city and Cold War relic in Greenland. Greene and his team were flying over the Greenland Ice Sheet in April,

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.

Radar surveys occasionally show evidence of the base, lurking there like an environmental time bomb under the ice. But in April 2024, using NASA's Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) strapped to the belly of the plane, scientists were able to resolve Camp Century in a new level of detail.
