Hayabusa2 has returned 5.4 grams of samples from C-type asteroid Ryugu in Dec 2020, and the analysis of the return samples is on-going! Now the research of these samples is open to anyone who is interested through the announcement of opportunity.
   Hayabusa symposium is an international symposium dedicated to advancement of the astromaterial and space research covering a wide range of topics. The main topics for Hayabusa symposium 2022 are new results of Ryugu sample analysis and related discussions with the results from remote-sensing, surface measurements, and sample analysis achieved by Hayabusa2 as well as OSIRIS-REx and other missions. 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 also welcomed.
   In order to synchronize with current results of planetary material sciences, this symposium will be jointly held with “The session of Antarctic meteorites in the 13th Symposium on Polar Science hosted by the National Institute of Polar Research (NIPR) ("45th Symposium on Antarctic Meteorites": Link).
Hayabusa symposium 2022 will be a hybrid event over 3 days between November 14 and 16th (both on site at Sagamihara, Japan, and online). Submissions of abstracts and presentations are accepted only in English

   We invite you all the academics and researchers in the scientific community to the Hayabusa symposium 2022. Let’s enjoy discussing the exciting latest results and on-going research of the Solar System scientific field.
   We look forward to seeing you at the Hayabusa symposium 2022!
