Mastcam-Z Looking Left
The Mastcam-Z cameras are on a workbench during their assembly at Malin Space Science Systems in San Diego. A square lightshade is mounted at the left end of the camera to reduce the scattered light that reaches the optics. Both cameras are almost identical, except for slight differences in the adjustable color filters that will provide more information about the mineralogy of the rocks on Mars.
NASA's Jet Propulsion Laboratory in Southern California built and will manage operations of the Mars 2020 Perseverance rover for NASA.
