Perseverance Mars rover finds possible biosignatures in Jezero Crater rock, NASA says
NASA says the Perseverance rover detected potential biosignatures in an ancient Jezero Crater rock called Cheyava Falls. Instruments spotted organics and key elements like sulfur, iron, and phosphorus in fine-grained sediments—prime material for preserving life traces. Scientists urge caution and call for sample return to confirm whether the signals are biological or not.
