Discovery in Greenland: NASA “accidentally” rediscovers a secret Cold War base
Below greenland ice And without waiting for it at all. This is the latest discovery National Aeronautics and Space Administration (NASA)In this case, to be precise, it is a ‘Rediscovery’Because this is something that was known about, but the cold temperatures of Greenland had buried it.
it’s about Camp Century, a former secret US baseAnd was found within the framework of aerial surveys of the area. These pictures were taken by the scientist last April chad greenBut they have become known now. The discovery was made during a flight in which a Radar equipment when examining ice sheets,
in great shape
“We were looking for ice beds and Camp Sanctuary appears. At first we didn’t know what it was” explains Alex Gardner, cryospheric scientist From NASA’s Jet Propulsion Laboratory (JPL). It was not he, but his partner Green, who captured the moment photography from airplane windowwhich was flying about 160 kilometers east pitufic space base United States Space Force. Next to a huge layer of snow, wonder: something suppressed,
This is Camp Century
known as “The city under the snow”, is a real Cold War RelicIt was constructed in 1959 by the United States Corps of Engineers. cutting a network of tunnels Within the layer near the surface of the ice sheet. His activity won’t last long anyway Abandoned in 1967When the snow started burying him. Now, it is located approximately 30 below the surface,

Radar is used to detect measures distance by sending radio wavesTiming the time taken to be reflected on the sensor. This allows experts to map the surface of the ice and its internal layers. Thus, previous studies that flew over Camp Century They found signs of a base under the ice,
But a new device was included in last April’s flights occasion (Synthetic Aperture Radar for Unmanned Aerial Vehicles), which helped create maps with greater dimensionality. “In new data, individual structures of secret city They are visible in a way that they have never been seen beforeGreen explains.
looking towards the future
Thanks for using the maps obtained with conventional radar They managed to estimate the depth at which Camp Century is located, and now the objective is to determine When will the thaw bring this forgotten secret base to light again?,
But their search goes even further, because they were looking for “Testing, verifying, and understanding capabilities and limitations UAVSAR will be used to map the interior layers of the ice sheet. With this, they now hope that these instruments will help in measuring the thickness of ice sheets in an environment similar to Antarctica, as well. Limited estimates of future sea level rise,
