How Perseverance’s Diverse Set of Cameras Will Perform Science on Mars

The latest rover has 23 cameras to help it navigate the surface of the red planet and perform scientific experiments.

A gentle breeze blowing at less than five kilometers an hour is the first sound that humanity has recorded from the surface of another planet. But the two microphones on NASA’s Mars Perseverance rover are a curiosity, a nice-to-have on a mission with far greater ambitions. The real excitement comes from Perseverance’s cameras.
The rover has 23 cameras. Nine of those are engineering cameras, which monitor the rover and its surroundings, helping determine where it’s going and if there are any hazards inon the way. Another seven cameras were for entry, descent and landing (EDL).
