NASA's Perseverance rover uncovers 4-billion-year-old impact evidence at Jezero Crater

NASA's Perseverance rover has found ancient rocks on the rim of Jezero Crater on Mars that preserve evidence of cosmic impacts dating back roughly 4 billion years. The discovery offers unique data about the most dynamic era in the solar system's history. NASA scientists describe the rocks as a geological "weather report" from the early solar system.
