Technicians working Mars 2020's System's Test 1 approach their workstation in the Spacecraft Assembly Facility at NASA's Jet Propulsion Laboratory in Pasadena, Calif. Over two weeks in January 2019, 72 engineers and technicians assigned to the 2020 mission took over the High Bay 1 cleanroom in JPL's Spacecraft Assembly Facility to put the software and electrical systems aboard the mission's cruise, entry capsule, descent stage and rover through their paces.

NASA's Jet Propulsion Laboratory will build and manage operations of the Mars 2020 rover for the NASA Science Mission Directorate at the agency's headquarters in Washington.
