[P-PS03] Small Solar System Bodies: Latest results and new perspectives on the Solar System evolution

Wed. May 25, 2022 3:30 PM - 5:00 PM Exhibition Hall Special Setting (1) (Exhibition Hall 8, Makuhari Messe)

convener:Tatsuaki Okada(Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency), convener:Daisuke Kuroda(Kyoto University), Arika Higuchi(University of Occupational and Environmental Health, Japan), Chairperson:Tatsuaki Okada(Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency), Arika Higuchi(University of Occupational and Environmental Health, Japan)

Small Solar System bodies including asteroids, comets, satellites, and IDPs preserve clues for understanding the origin and evolution of the Solar System and investigating the sources of building blocks of life. Many discoveries have been made by ground-based and space-borne observations and direct explorations using spacecrafts. Evident and precise data on solar system evolution have been obtained by analyses of extraterrestrial materials such as meteorites, IDPs, and samples returned by space missions. New perspectives are expected by the collaboration of these results with theoretical and experimental studies. In this session. new results of theoretical, experimental and observational studies on small Solar System bodies are focused, as well as the latest information by Hayabusa2 and OSIRS-REx missions. Scientific expectations are also discussed for the high sensitive large-area observatories such as LSST and JWST and for the future planetary missions like Hayabusa2-extended, MMX, Destiny+, Hera, and Comet Interceptor. Missions to unexplored bodies like Lucy to Jupiter Trojans and Psyche to a M-type asteroid, and the planetary defense to avoid from collision of asteroids to Earth are also within the scope of this session.
