This session will cover all aspects of ice giant (IG) systems including (but not limited to) the atmospheric structure and composition, magnetospheres, interiors, satellites, and rings of the IGs. Interdisciplinary, crosscutting themes of ice giant planet exploration, such as the relationship to exoplanetary science and connections with heliophysics will also be considered in the session. The session will consist of a combination of solicited and contributed oral and poster presentations on new, continuing, and future studies of the ice giant systems and the importance of the ice giants to models of the formation and evolution of the giant planets and the Solar System.

We welcome abstracts that:

Address the current understanding of ice giant systems, including atmospheres, interiors, magnetospheres, rings, and satellites including Triton.
Advance our understanding of the ice giant systems in preparation for future exploration, both by remote sensing and in situ.
Discuss what the ice giants can tell us about solar system formation and evolution leading to a better understanding of the current structure of the solar system and its habitable zone as well as extrasolar systems.
Address outstanding science questions requiring future investigations including from spacecraft, remote sensing, theoretical, and laboratory work necessary to improve our knowledge of the ice giants and their relationship to the gas giants and the solar system.
Present concepts of missions, instruments, and investigations relevant to future exploration of the ice giant planetary systems.
Due to the prioritization of the Uranus Orbiter and Probe (UOP) mission theme by the 2023 National Academy of Sciences "Origins, Worlds, and Life" planetary science decadal survey, we encourage the submission of abstracts that discuss broad science goals as they relate to the proposed objectives of the UOP mission. We welcome abstracts discussing measurements that could be made of the planet, satellites, and rings via remote sensing and/or in situ observations.

Space environments, including magnetospheres, ionospheres, atmospheres, and associated auroral regions, are fundamental components of planetary and cometary systems. They are shaped by solar radiation and influenced by a wide range of processes such as space‑weather variability, solar wind dynamics, and changes in the neutral atmosphere. Within these systems, ionospheres play a central role in governing overall dynamics: they form the critical interface linking the neutral atmosphere, exosphere, and surrounding plasma environments (e.g., the solar wind at Mars, Venus, Pluto, and comets, or the Kronian magnetosphere at Titan). Understanding how each unmagnetized body responds to these external and internal drivers is essential for comparative aeronomy. While these bodies may share broadly similar behaviours, their distinct physical characteristics lead to scientifically significant differences, including in their auroral emissions and ionospheric responses.
This session focuses on the space environments, including auroral phenomena of Mars, Venus, Pluto, Titan, Jovian moons, comets, and related comparative studies, including analogies with the ionospheres of magnetized bodies. We invite abstracts addressing remote‑sensing and in‑situ observations, modelling efforts, instrumentation, and mission concepts.
Topics may include, but are not limited to: day‑ and night‑side ionospheric variability; sources and drivers of ionization; ion‑neutral interactions; current systems; comparative ionospheric and auroral studies across bodies; and solar‑wind–ionosphere coupling, including the response of neutral and ionized regimes to transient space‑weather events. Abstracts addressing general plasma processes and atmospheric escape are also welcome.

Saturn's moon Titan, despite its satellite status, has nothing to envy the planets: it has planetary dimensions, a substantial and dynamic atmosphere, a carbon cycle, a variety of geological features (dunes, lakes, rivers, mountains and more), seasons, and a potential hidden ocean. It even now has its own mission: Dragonfly, selected by NASA in the frame of the New Frontiers program. In this session, scientific presentations are solicited to cover all aspects of current research on Titan: from its interior to its upper atmosphere, using data collected from the Cassini-Huygens mission (2004-2017) and/or from telescopes (e.g., ALMA, JWST) and/or based on modelling and experimental efforts to support the interpretation of past and future observations of this unique world.

Jupiter’s icy moons - Europa, Ganymede, and Callisto - are at the center of planetary science curiosity, particularly in the search for habitability in the solar system. In this context, ESA’s Jupiter Icy moons Explorer (Juice) is on its way to the Jovian system after its successful Venus gravity assist in August 2025 and is joined by NASA’s Europa Clipper following its launch in October 2024 and its Mars flyby in March 2025.

This session invites contributions from the science community related to these two missions’ objectives. This includes, but is not limited to, better understanding of Jupiter icy moons’ surface properties, internal structures and dynamics, as well as implications for habitability. The session will also cover the moons’ complex interactions with the space environment and their dynamical evolution within the Jovian system. Finally, abstracts related to observations and future science opportunities during cruise are also welcome.

As we reflect on this unique opportunity of having two spacecrafts in the Jovian system at the same time, the session will highlight the scientific opportunities offered by each mission as well as by the dual-spacecraft configuration, emphasizing the synergistic potential of Europa Clipper and Juice.
