Scientists may have discovered a new mineral on Mars that could provide clues about the planet’s dynamic surface and its potential to support life. A research team led by Janice Bishop at NASA Ames Research Center has been studying unusual layers of iron sulfates on the Martian surface, which they believe may represent an undiscovered mineral.
The team analyzed data from Mars orbiters and discovered two sites with a unique spectral signature, indicating the presence of an iron-bearing mineral called ferric hydroxysulfate. By analyzing this data, Bishop and her team were able to recreate the conditions that form this mineral in their laboratory, suggesting it only forms when hydrated ferrous sulfates are heated in the presence of oxygen.
The discovery could provide new insight into Mars’ surface, as the findings suggest parts of the planet have been chemically and thermally active more recently than previously believed. The team also hopes to find evidence of this mineral on Earth to officially recognize it as a new mineral.
The paper detailing the research was published in the journal Nature Communications on August 5. Further study of this mineral could provide valuable information about Mars’ geology and its potential for supporting life.
