In a test facility at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, the Europa Imaging System (EIS) wide-angle-camera (WAC) team took its “first light” image with the WAC telescope and detector in December 2021. The image features APL's Alexandra Ocasio Milanes (left), an EIS systems engineer, and Joe Centurelli, the WAC lead optical engineer. The image was taken to confirm the camera optics are in focus. Following this successful test, the WAC completed vibration testing and is undergoing thermal testing to simulate the environment EIS will experience during launch and operations in space. The camera will then be integrated with its data processing unit for end-to-end electromagnetic tests, followed by optical characterization in a simulated space environment in the APL Optical Calibration Facility. After testing, the APL team will ship the WAC to NASA’s Jet Propulsion Laboratory in Pasadena, California, for integration with the Europa Clipper spacecraft.
