[P-PS03] Small Solar System Bodies: New perspectives on the origin and evolution of the Solar System

Wed. May 24, 2023 10:45 AM - 12:15 PM 301A (International Conference Hall, Makuhari Messe)

convener:Tatsuaki Okada(Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency), Fumi Yoshida(University of Occupational and Environmental Health, Japan), Sota Arakawa(Japan Agency for Marine-Earth Science and Technology), Ryota Fukai(Japan Aerospace Exploration Agency), Chairperson:Ryota Fukai(Japan Aerospace Exploration Agency), Sota Arakawa(Japan Agency for Marine-Earth Science and Technology), Tatsuaki Okada(Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency), Fumi Yoshida(University of Occupational and Environmental Health, Japan)

Small Solar System bodies including asteroids, comets, satellites, and the interplanetary dust particles (IDPs) preserve clues for the understanding of the origin and evolution of the Solar System and the investigation of the sources of the building blocks of life. Many discoveries have been made in recent years by the ground-based and space-borne observations and the direct in situ explorations using spacecrafts. Evident and precise data on the origin and evolution of the Solar System have been obtained by analyses of extraterrestrial materials such as meteorites, IDPs, and the samples returned by space missions. New insights are expected by the collaboration of these data-based 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 results of remote sensing and sample analysis by Hayabusa2, OSIRS-REx , and DART 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#, MMX, Destiny+, Hera, and Comet Interceptor, Lucy, and Psyche. Topics on the science and instruments of the Japanese next small body mission whose working group studies are just started as well as the studies for the planetary defense are also within the scope of this session.
