Engineer Chris Chatellier stands next to a target board with 1,600 dots. The board was one of several used on July 23, 2019, in the Spacecraft Assembly Facility's High Bay 1 at NASA's Jet Propulsion Laboratory in Pasadena, California, to calibrate the forward-facing cameras 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.
