The Ice Giants:  Exploring the Planetary Systems of Uranus and Neptune

Session ID#: 157831

Session Description:
The Uranus and Neptune planetary systems are among the most intriguing and least explored in our Solar System, presenting exciting opportunities for new discoveries and serving as high-priority targets for future space missions.  This session invites submissions of interdisciplinary topics covering all aspects of ice giant systems, including interior structure, atmospheres, ionospheres, magnetospheres, rings, satellites (including Triton), formation, and evolution.  Our session welcomes presentations that advance our understanding of ice giant systems from a range of perspectives including observations, modeling, theory, and laboratory work.  With a Uranus orbiter and probe ranked as the highest-priority new Flagship mission by the Planetary Decadal Survey (2023-2032), we warmly welcome relevant studies in preparation for future remote sensing and in situ explorations, including mission concepts and instrument design studies relevant to the ice giant systems.  We also encourage comparative studies between the Uranus/Neptune systems and other planetary bodies, within our solar system and beyond.
