In this image, taken on June 5, 2019, engineers at NASA's Jet Propulsion Laboratory in Pasadena, California, take a moment after attaching the remote sensing mast to the Mars 2020 rover in the Spacecraft Assembly Facility's High Bay 1 clean room. Full integration of the mast—a process that includes installation of science instrument sensors, electrical wiring and checkout—continued into the following week, concluding on June 11.
