Perseverance Finds Multiple Water Events in Jezero Crater

NASA's Perseverance rover has found that a puzzling rock formation in Mars' Jezero crater underwent three separate episodes of water-driven alteration, suggesting the area was a crossroads for ancient aqueous systems. Scientists say the olivine-rich Margin unit preserves a complex record of groundwater and lake interaction, strengthening its status as a key target in the search for signs of ancient life.
