[P-PS01] Outer Solar System Exploration Today, and Tomorrow

Fri. May 30, 2025 10:45 AM - 12:15 PM 301B (International Conference Hall, Makuhari Messe)

convener:Jun Kimura(The University of Osaka), Kunio M. Sayanagi(NASA Langley Research Center ), Fuminori Tsuchiya(Planetary Plasma and Atmospheric Research Center, Graduate School of Science, Tohoku University), Shuya Tan(Japan Agency for Marine-Earth Science and Technology), Chairperson:Yoshifumi Saito(Solar System Science Division, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency), Shotaro Sakai(Department of Geophysics, Graduate School of Science, Tohoku University)

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, 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 and beyond), we also solicit contributions on future missions to explore giant planet systems (e.g., Uranus Orbiter and Probe), 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 the planning and results from observing upcoming stellar occultations by Uranus, and about new scientific results generated using data returned by space telescopes such as the James Webb Space Telescope (JWST).

12:00 PM - 12:15 PM
