Los Angeles CA (SPX) Aug 09, 2025
New research led by the SETI Institute has identified an unusual iron sulfate on Mars that may represent a previously unknown mineral, offering new insights into the planet's thermal and geochemical history. The study, published in Nature Communications, reveals the presence of ferric hydroxysulfate, a mineral that likely formed through heating and oxidation of more common hydrated sulfates.
