Europa Ultraviolet Spectrograph
The Europa Ultraviolet Spectrograph (Europa-UVS) is an ultraviolet spectrograph imager that will be flown on board the Europa Clipper mission to Jupiter's moon Europa. The Europa-UVS will be able to detect small erupting plumes and will provide data about the composition and dynamics of Europa's thin exosphere.
