Uranus and Neptune systems are high-priority targets for near-future exploration by space missions possibly with atmospheric probes/landers for in-situ explorations of various target bodies. This session invites submissions of interdisciplinary topics covering all aspects of ice giant systems: the magnetospheres/satellites/rings/atmospheres/ionospheres/interior structure/magnetic dynamo, including their formation/evolution/variation. We also invite studies of materials at extreme conditions through experiments and simulations to provide novel insights on the conditions (e.g. phase diagrams/equations of states/transportation) of the atmospheres at depth and planetary/satellite interiors. Our session especially welcomes presentations that advance our understanding of ice giant systems in preparation for future remote sensing and in situ explorations. We also encourage comparative studies between aspects of the Uranus/Neptune systems and other planetary bodies within and beyond our solar system. We solicit presentations on observations, modeling, theory, and laboratory work, and concepts/design for missions and instruments relevant for future exploration of the ice giant systems.
