Preliminary Shape Modeling for the Asteroid (25143) Itokawa, AMICA of Hayabusa Mission

Hayabusa mission is a sample return program of ISAS/JAXA. The spacecraft was renamed from MUSES-C, which was launched to the target asteroid (25143) Itokawa at May 9, 2003. Scheduled arrival is summer of 2005. We are a group of shape modeling for selecting landing sites, for characterizing geologic context on the basis of a telescope (AMICA: Asteroid Multiband Imaging Camera) and a laser range finder (LIDAR: Light Detection And Ranging). We show preliminary results of a type of image-based one by means of ground experiments with proto-model of AMICA.
