NASA’s Perseverance Discovers Organic Carbon in Jezero Mudstones with Redox-Driven Mineral Textures Hinting at Possible Martian Biosignatures
To the point
Researchers report that Perseverance found Jezero Crater mudstones with organic carbon and textures that could be biosignatures, including iron phosphate and iron sulfide formed by post‑depositional redox processes that may reflect microbial activity or abiotic chemistry, and they call for further core analysis with Earth instruments to determine the origin of the minerals and organics and what this says about ancient Martian habitability.
