Jezero Crater (IMAGE) Southwest Research Institute Caption The Jezero Crater on Mars, the landing site for NASA's Mars 2020 mission, shows evidence of water carved channels and transported sediments. Colors highlight the distribution of clays and carbonates. An SwRI scientist updated Mars chronology models and predicted that these surfaces could have formed more than 3 billion years ago, which means they are hundreds of millions of years older than previously thought.
