Summary

NASA’s Perseverance rover has found promising evidence of ancient microbial life on Mars in a rock sample called “Sapphire Canyon.” This sample, taken from the Bright Angel formation in Jezero Crater, contains “leopard spots”—mineral and chemical patterns suggestive of biosignatures. These spots are rich in iron-based minerals. This discovery marks Perseverance’s strongest indication yet that Mars may have once harbored life, fueling excitement for future analysis of the rock sample.
