Thermal Imager's First Light Test
Published: January 10, 2022
Europa Clipper’s thermal imager (called E-THEMIS) is shown here in its protective enclosure, viewing the Tempe Campus of Arizona State University during testing on a rooftop lab.
The thermal imager will use infrared light to distinguish warmer regions on Europa’s surface, where liquid water may be near the surface or might have erupted onto the surface. The thermal imager will also characterize surface texture to help scientists understand the small-scale properties of Europa’s surface.
