[P-PS03] [EE] Regolith Science

Tue. May 23, 2017 9:00 AM - 10:30 AM 103 (International Conference Hall 1F)

convener:Koji Wada(Planetary Exploration Research Center, Chiba Institute of Technology), Patrick Michel(University Cote d'Azur, Cote d'Azur Observatory, CNRS), Akiko Nakamura(Graduate School of Science, Kobe University), Kevin John Walsh(Southwest Research Institute), Chairperson:Akiko Nakamura(Graduate School of Science, Kobe University)

This session welcomes broad topics related to regolith on various celestial bodies, such as asteroids, comets, the Moon, the martian moons, Mars, etc. Papers on the formation, evolution, and alteration processes of regolith particles and regolith systems on the surface of planetary bodies, remote and in-situ observational results and techniques, analyses and results of returned samples, and laboratory, numerical, and theoretical studies on the fundamental physical and chemical processes are all welcome.
