In a new Mars update (the first update can be read here), mysterious rocks have been found and there may have been a fairly recent volcanic eruption.
NASA’s Perseverance Rover discovered some unusual rocks in the Jezero Crater and has been studying them with two of its instruments – the rock-zapping SuperCam laser and the WATSON (“Wide Angle Topographic Sensor for Operations and Engineering”) camera.
It’s unclear whether these rocks are sedimentary or volcanic. If they are volcanic in origin, this would be a huge help for experts understanding the history of the crater that billions of years ago had a lake and a river delta. If the rocks turn out to be sedimentary, they may have been created over a long period of time from sand, silt, and clay which may hold clues to ancient Martian life (if there ever was any).
