Perseverance rover discovers Mars rocks with potential biosignatures in Jezero Crater

Perseverance rover found Mars rocks with unusual nodules and organic material potentially indicating ancient microbial life. These rocks in Jezero Crater contain organic carbon, iron, sulfur, and phosphorus arranged in patterns similar to Earth's microbial processes, suggesting a possible energy source for ancient organisms. The findings are considered potential biosignatures and a prioritized sample has been collected for potential return to Earth for further analysis.
