A mechanical engineer in a clean room at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, installs the detector electronics for the engineering model of the Wide Angle Camera (WAC), one of two cameras that make up the Europa Imaging System (EIS). EIS is one of the science instruments that will fly aboard Europa Clipper. EIS data will offer fresh insights into Europa's geological structure and processes and will be used to search for evidence of recent or current geologic activity, including potential erupting plumes.
