Hidden Glaciers on Mars? The Hecates Tholus Discovery

Bedtime Astronomy

Scientists have identified Hecates Tholus, a volcano on Mars, as a potential site for massive underground glaciers buried beneath volcanic debris. By comparing it to Deception Island, researchers found geological features — including crevasses and push moraines — that suggest moving ice beneath the surface.

If confirmed, accessible equatorial ice could transform future human exploration and reshape planetary protection policies. The study also points to volcanic activity as a key factor in preserving ancient water reserves on the Red Planet.
