Mars sample Sapphire Canyon hints at possible biosignature, not life

NASA's Perseverance rover found a 1‑meter rock core from Cheyava Falls at Bright Angel in Jezero Crater showing leopard-spot textures and minerals like vivianite and greigite, indicating ancient water and redox chemistry that could feed microbes. While this is among the strongest potential biosignatures yet, it is not proof of life and abiotic explanations cannot be ruled out; further Earth-based analyses on returned samples are needed.
