| Outline of Final Research Achievements |
In order to clarify the evolution of early solar system, we performed (1) analysis of small dust particles returned by Hayabusa mission from S-type asteroid Itokawa, which showed that Itokawa experienced very strong impact that disrupted parent asteroid of Itokawa, (2) heating experiments of hydrous carbonaceous chondrites in order to understand spectral changes during hearting of C-type asteroids. The experiments were performed in vacuum and the heated samples were never exposed to atmosphere after heating and thus we obtained spectra that are free of atmospheric water.
