[P-PS09] Mars and martian moons

Tue. May 27, 2025 10:45 AM - 12:15 PM 304 (International Conference Hall, Makuhari Messe)

convener:Hideaki Miyamoto(University of Tokyo), Tomoki Nakamura(Department of Earth and Planetary Materials Sciences, Faculty of Science, Tohoku University), Hidenori Genda(Earth-Life Science Institute, Tokyo Institute of Technology), Takeshi Imamura(Graduate School of Frontier Sciences, The University of Tokyo), Chairperson:Tomohiro Usui(Japan Aerospace Exploration Agency), Takeshi Imamura(Graduate School of Frontier Sciences, The University of Tokyo), Koji Wada(Planetary Exploration Research Center, Chiba Institute of Technology), Kiyoshi Kuramoto(Department of Cosmosciences, Graduate School of Sciences, Hokkaido University), Hideaki Miyamoto(University of Tokyo)

Mars exploration has accelerated; at least one robotic mission has been continuously operating near Mars since 1997, and the number of spacecraft observing Mars has steadily increased. There are now three rovers on the surface of Mars and eight spacecraft in orbit around Mars. Several new missions are about to launch, including the MMX mission to explore Phobos, Deimos, and Mars, scheduled for launch in 2026. This session will discuss recent results from a wide range of Mars studies, including the interior, surface, atmosphere, plasma environment, and the Mars system, including its two satellites. Abstracts on instrumentation, theoretical studies, and future mission plans are also encouraged for this session, as both the presenters and the audience would greatly benefit from the ensuing discussion and feedback.
