When we think of ice on Mars, we typically think of the poles, where we can see it visibly through probes and even ground-based telescopes. But the poles are hard to access, and even more so given the restrictions on exploration there due to potential biological contamination. Scientists have long hoped to find water closer to the equator, making it more accessible to human explorers. There are parts of the mid-latitudes of Mars that appear to be glaciers covered by thick layers of dust and rock.
So are these features really holding massive reserves of water close to where humans might first step foot on the red planet? They might be, according to a new paper from M.A. de Pablo and their co-authors, recently published in Icarus.
The key might be a small, volcanic island in Antarctica. Known as Deception Island, it’s a volcano that has covered some massive glaciers surrounding it with ash and dust from a series of eruptions in the 60s and 70s. The authors think they found a volcano on Mars with a similar history known as Hecates Tholus.
