The existence of Camp Century remained classified until 1997, when a report on the history of nuclear weapons in Greenland was published.

The base, which was strategically located near Soviet borders, also aimed to exploit Arctic natural resources amid escalating tensions during the Cold War.

Project Iceworm was designed to create a vast network of tunnels for deploying intermediate-range ballistic missiles, reflecting the military ambitions of the era.

Greenland has urged Denmark to take responsibility for the clean-up of the site, citing the original agreement regarding the base's environmental management.

NASA's recent radar imaging has uncovered Camp Century, a Cold War-era military base buried beneath the Greenland ice sheet, originally part of Project Iceworm aimed at constructing nuclear missile tunnels.

Cryospheric scientist Chad Greene highlighted that this new radar data revealed the facility's structures in unprecedented detail, although interpreting these images can be complex due to radar distortions.

Previous radar scans had identified the site but lacked the clarity achieved in this recent survey, which now shows distinct features of the hidden facility.

After its abandonment in 1967, the base was buried under accumulating snow and ice, with its structures now lying at least 30 meters below the surface.

Concerns have been raised regarding the buried nuclear, biological, and chemical waste at Camp Century, including significant quantities of diesel fuel and wastewater.

As Greenland's ice sheet continues to melt, the environmental implications of such buried waste become increasingly alarming, especially in light of accelerated ice loss observed in recent years.

NASA plans to leverage the data collected from these surveys to enhance future studies of Earth's ice sheets and their responses to climate change.

The Danish government had cooperated with the project but never fully endorsed it, leading to its eventual abandonment due to harsh Arctic conditions.
