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

2026年5月27日(水) 13:45 〜 15:15 302 (幕張メッセ国際会議場)

座長:深井 稜汰(宇宙航空研究開発機構)、荒川 創太(海洋研究開発機構)

Asteroids, comets, satellites, and other small solar system bodies
provide crucial clues for understanding the origin and evolution of
the solar system and for supplying the building blocks of life.
Numerous discoveries have been made through ground-based and space
telescope observations and direct exploration by spacecraft.
Meanwhile, in addition to analyzing meteorites and cosmic dust, the
analysis of returned samples via sample return missions has enabled
the acquisition of empirical and highly precise information.
Integrating observational research, sample analysis studies, and
theoretical/laboratory experiments is expected to foster new
perspectives in planetary science. This session will focus on the
latest theoretical and experimental research on solar system small
bodies (meteorite & sample return analyses via high resolution
analytical techniques), the latest results from ground-based
observations, and new insights from current missions such as
OSIRIS-REx and DART. It will also cover high-sensitivity observations
expected in the large telescopes like LSST and JWST, as well as the
Hayabusa2#, MMX, Destiny+, Hera, Comet Interceptor, Lucy, and Psyche,
and the scientific progress achievable through their coordination.
Furthermore, we encourage active discussion on the next-generation
asteroid exploration mission concepts and payload studies currently
under Working Group consideration, as well as on planetary defense.
