Mars rocks harbor robust organic carbon, but life remains unproven
TL;DR Summary
NASA’s Perseverance rover has detected macromolecular carbon—durable, complex organic matter—in two ancient mudstones in Jezero crater, identified by the SHERLOC spectroscopy instrument. The rocks—Cheyava Falls and a formation at the Bright Angel outcrop—show organics associated with different mineral settings, suggesting multiple organic-forming processes over time. While this represents the most extensive organic detection on Mars to date, the findings do not prove biology; the origin could be abiotic. Also, a 2026 funding shift means Mars Sample Return is unlikely this decade, so the cores remain on Mars for now.
