Where Will NASA's 2020 Mars Rover Land?

NASA's next Mars rover may touch down in a big crater called Jezero. The 28-mile-wide (45 kilometers) Jezero Crater emerged as the frontrunner among 30 or so potential locales during the second landing-site workshop for NASA's 2020 Mars rover mission, which about 200 scientists and engineers attended here from Aug. 4 through Aug. 6. Jezero is rich in clay minerals and once harbored a basin lake and drainage network that covered a huge catchment area, scientists say.
