Abstract Europa, the most visibly active icy moon of Jupiter, is a prime target for search life in outer solar system. Two spacecraft missions, Europa Clipper from National Aeronautics and Space Administration (NASA) Jupiter Icy Moon Explorer (JUICE) European Agency (ESA), will observe its surface, probe interior structure, characterize space environment starting 2030. Occasional eruptions water sourced Europa’s may provide window on conditions habitability moon. Here, we investigate storage evolution briny ice shell propose framework to interpret spectral, thermal, radar gravity data collected by future missions. We show that it possible discriminate between erupting deep ocean or shallow liquid reservoirs using combined measurements material’s salinity, surface temperature thickness.

Abstract NASA’s Europa Clipper mission is designed to provide a diversity of measurements further our understanding the potential habitability this intriguing ocean world. The mission’s Ultraviolet Spectrograph (Europa-UVS), built at Southwest Research Institute (SwRI), primarily “plume finder” and tenuous atmosphere investigation. science objectives Europa-UVS are to: 1) Search for characterize any current activity, notably plumes; 2) Characterize composition sources volatiles identify signatures non-ice materials, including organic compounds, in local space environment. observes photons 55–206 nm wavelength range moderate spectral spatial resolution along 7.5° slit composed 7.3°×0.1° 0.2°×0.2° contiguous sections. A variety observational techniques nadir pushbroom imaging, disk scans, stellar solar occultations, Jupiter transit observations, neutral cloud/plasma torus stares employed perform comprehensive study Europa’s atmosphere, plumes, surface, This paper describes investigation’s plans, instrument details, concept operations, data formats context primary assessment goals.
