SuperCam is Not Seeing Red
The mast-mounted portion of SuperCam awaits integration into the Perseverance rover. Part of SuperCam is contained in the belly of the rover, while this unit, containing the laser, infrared spectrometer, telescope, camera, and electronics, sits at the top of the remote sensing mast. The red "remove before flight" cover protects a clear window in front of the telescope and camera and was removed when SuperCam was installed in the rover.
NASA's Jet Propulsion Laboratory in Southern California built and will manage operations of the Mars 2020 Perseverance rover for NASA.
