Scope 
The giant planets shape our solar system. The physical and chemical processes they harbor provide unique opportunities to study the phenomena relevant for studying Earth and other planets, including exoplanetary systems. In this session, we welcome diverse topics encompassing the giant planets and their moons and rings, including their origins, interiors, atmospheres, compositions, surface features, electromagnetic fields, and plasma environments. To advocate for current and future outer planets exploration (Juno, New Horizons, JUICE, Europa Clipper, Dragonfly, OPENS-0, and beyond), we also solicit contributions on future missions to explore giant planet systems (e.g., Uranus Orbiter and Probe, and the OPENS Program), including how to develop better international cooperation. Discussion in this latter category will include progress in developing a solar sail mission concept for observing the Jupiter system and its Trojan asteroids. We also solicit presentations about new scientific results generated using data returned by space telescopes such as the James Webb Space Telescope (JWST).
