Scope
The Hayabusa Symposium 2026 brings together researchers studying extraterrestrial samples, focusing on Hayabusa, Hayabusa2, OSIRIS-REx, upcoming MMX, and the other future missions like NGSR. With Ryugu and Bennu samples now distributed to the scientific community worldwide, this symposium will explore cutting-edge research and foster collaboration.
In addition, related studies with the results from remote-sensing and surface measurements by space missions, ground observations of primitive bodies and exoplanets, and numerical studies should be comparatively discussed. The other regular topics on any extraterrestrial materials and primitive bodies in the Solar System by theoretical, observational, and experimental studies, new methodology of analysis, and future space missions are highly welcomed!
