NASA's Perseverance Mars rover will soon encounter rare rubble dumped on the Red Planet by an ancient asteroid impact, kicking off a new phase of science observations as the rover continues its arduous trek to the western edge of Jezero Crater.
Scientists working on the mission announced last week that Perseverance is enroute to Dox Castle, a patch of Jezero Crater whose rocks may have been dumped by the asteroid impact that carved the crater out.
