Outline of Final Research Achievements

Fine particles collected from the surface of Asteroid Itokawa by the “Hayabusa” mission were examined based on the preliminary examination results, and the following results were achieved. (1) The analyzed samples are almost representative for the whole collected samples although they are very small in amount, and it was finally confirmed by comparing with meteorites that the materials on the S-type Asteroid correspond to meteorites, particularly ordinary chondrites (LL chondrites). (2) We successfully obtained dynamic picture about asteroid surface evolution that space-weathering proceeds by combined and repeated processes of particle formation due to impact, space-weathering rim formation on particle surfaces due to solar wind implantation, and particle abrasion due to particle motion.
