Story summary

NASA's Perseverance rover collected Sapphire Canyon, a rock sample from Jezero Crater, suggesting biosignatures of ancient life on Mars.
The sample contains clay, silt, organic carbon, sulfur, rust, and phosphorus—plus minerals vivianite and greigite—implying past microbial activity.
A sample-return mission is planned but delayed until at least 2040 due to budget constraints, with potential implications for understanding life's origins.
