Cheyava Falls at Jezero Crater Reveals Water History, Organic Carbon, and Redox Mineral Patterns—Life Not Proven (Step 3) with Further Tests Planned
To the point
Scientists on NASA’s Perseverance mission found signs of ancient water and organic material in a rock at Jezero Crater, including iron minerals vivianite and greigite and leopard‑spot patterns that suggest chemical reactions between organics and iron, but these findings do not prove life and more tests after Mars sample return are needed to rule out non-biological explanations.
