- Perseverance rover explored Jezero Crater to study Martian geological processes and search for biosignatures.
- Discovered organic-carbon-bearing mudstones in the Bright Angel formation with iron phosphate and sulfide minerals.
- Redox reactions involving organic matter likely produced iron-phosphate and iron-sulfide minerals at low temperatures.
- Potential biosignatures identified, warranting further study to determine their origin.
- Findings highlight the importance of returning Martian samples to Earth for detailed analysis.
