NASA's Perseverance rover has potentially discovered the strongest evidence yet of ancient life on Mars. The Cheyava Falls rock sample, collected from Jezero Crater, exhibits unusual leopard spot markings and contains organic compounds. Scientists believe these features could represent biosignatures resulting from microbial activity billions of years ago, though further research is needed to confirm this groundbreaking possibility.

NASA will reveal new findings from the Perseverance rover on September 10, 2025. The focus is on the 'Sapphire Canyon' rock sample from Jezero Crater. Scientists are intrigued by chemical patterns and organic molecules. These could indicate ancient biological processes. The discovery strengthens the case for past microbial life on Mars.
