The highly anticipated Europa Clipper mission, set to launch in 2024, will investigate Jupiter’s moon Europa. This icy moon with a subsurface ocean is considered one of the most enticing places in our Solar System where life might exist. To look beneath Europa’s icy crust, the Clipper mission has a host of instruments looking for plumes and ‘hot spots.’

A thermal emissions imager, called E-THEMIS (Europa Thermal Emission Imaging System) recently passed a major testing hurdle recently by capturing its “first light” images with its infrared camera.
