In this picture — taken on May 23, 2019, in the Spacecraft Assembly Facility's High Bay 1 clean room at the Jet Propulsion Laboratory in Pasadena, California — engineers re-install the cover to the remote sensing mast (RSM) head after integration of two Mastcam-Z high-definition cameras that will go on the Mars 2020 rover.

JPL is building and will manage operations of the Mars 2020 rover for the NASA Science Mission Directorate at the agency's headquarters in Washington.
