The Juno spacecraft performed flybys of Ganymede, Europa, and Io between 2021 and 2025. The data collected during these flybys provided unprecedented views of these moons. Juno’s multi-instrument measurements include high-resolution imagery in visible, ultraviolet, and infrared of the surface geology and composition, microwave sounding of the subsurface, gravitational sounding of the interior, as well as the in-situ characterization of the electromagnetic fields and particles environment of these moons. Concurrent observations from space-based and ground-based observatories, e.g. from JWST and ALMA, continue to reveal new features of these satellites. This session welcomes papers related to Juno’s flybys of Europa, Ganymede and Io as well as space-based and ground-based remote observations of these moons, including the surface composition and processes, ice-shell structure, ocean dynamics, the structure and dynamics of deeper layers as well as atmospheric and space environment studies. Modeling work that provides context and interpretation of measurements are equally welcome.
