Summary

Story summary

A Nature Communications study identifies a potential new mineral, ferric hydroxysulfate, on Mars.
Led by Dr. Janice Bishop, researchers analyzed sulfate minerals near Valles Marineris, indicating a wetter past on Mars.
The study suggests volcanic heat and geothermal energy transformed common hydrated sulfates into ferric hydroxysulfate, formed more recently than adjacent terrain.
Laboratory experiments showed heating specific sulfates can induce this transformation, implying ongoing chemical and thermal activity on Mars.
