The Perseverance rover landed inside Mars’ Jezero Crater on Feb. 18, on a mission to hunt for evidence of past microbial life and collectsamples for future return to Earth. For the past month, the mission team has been checking out Perseverance’s seven science instruments and its various subsystems, and the rover has jumped through every hoop.
