Outline of Final Research Achievements |
We developed a method for high resolution 3D shape reconstruction of asteroids with a combination of SPC and SfM methods and a 3D geographical information system for asteroid data analysis. By utilizing these research environment, we analyzed image data of the asteroid Itokawa taken by the Hayabusa spacecraft to reveal new views on a small rubble-pile asteroid. We describe a resurfacing history of Itokawa by impact events. It is suggested that Itokawa was suffered by a global resurfacing event on several Myr ago, which is consistent with evidence from samples recovered from Itokawa.
