How many cameras does the Perseverance rover have? The answer is 19.
NASA’s Perseverance rover carries 19 cameras for scientific imaging, navigation, engineering support, and documentation of its activities on Mars. These cameras are distributed across the rover rather than forming one single camera unit.
Its imaging systems include the Mastcam-Z stereo camera, navigation cameras, hazard-avoidance cameras, and cameras associated with instruments such as SHERLOC and CacheCam. The rover also has dedicated cameras used during landing and operations.
The total refers to cameras on Perseverance itself. Ingenuity, the helicopter transported to Mars with the rover, had its own separate cameras and is not included in the rover’s camera count.
