[P-PS08] Lunar Science and Exploration

Fri. May 30, 2025 9:00 AM - 10:30 AM 302 (International Conference Hall, Makuhari Messe)

convener:Yusuke Nakauchi(Ritsumeikan University), Keisuke Onodera(Institute for Planetary Materials, Okayama University), Yoshiaki Ishihara(Japan Aerospace Exploration Agency), Ayame Ikeda(Geological Survey of Japan, AIST), Chairperson:Hiroshi Nagaoka(Ritsumeikan University), Risa Miyazaki(Japan Aerospace Exploration Agency)

Scientific data sets acquired by the Japanese lunar mission SELENE (Kaguya)
have become the standard of lunar science. Other missions such as Chandrayaan series, LRO, GRAIL, LCROSS, LADEE, THEMIS-ARTEMIS, and Chang'e series and ground observations also have provided new knowledge of the Moon. Apollo/Luna samples and lunar meteorite analyses are also being advanced. Last year, the Japanese Smart Lander for Investigate the Moon (SLIM) succeeded in a pinpoint landing. Furthermore, in collaboration between JAXA and ISRO, the Lunar Polar Exploration (LUPEX) is planned to explore the subsurface water resources in 2026. In concurrence with these studies, some countries, including Japan, plan near-future lunar missions.
This session will discuss scientific results based on newly acquired lunar data, strategies for future missions, lunar sample analyses, and theoretical and experimental studies.
