Hayabusa (MUSES-C: Asteroid Sample-return Spacecraft) is a Japanese engineering spacecraft by the Institute of Space and Astronautical Science of Japan Aerospace Exploration Agency (ISAS/JAXA) aiming at sample return from S-type asteroid (25413) Itokawa (Fujiwara et al., 2006). Between September and November 2005, Hayabusa observed Itokawa by Asteroid Multiband Imaging CAmera (AMICA) and Near Infrared Spectrometer (NIRS). A filter wheel of AMICA has a wide bandpass filter and ECAS (Eight Color Asteroid Survey) narrowband filters: 380 (ul), 430 (b), 550 (v), 700 (w), 860 (x), 960 (p), and 1,010 nm (zs) (Nakamura et al., 2001; Saito et al., 2001). AMICA observed the whole surface of Itokawa with the solar phase angle around 10 degree with nominal resolution 70 cm from the Home Position (HP) at approximate distance 7 km. Observations from closer distances were also performed with resolution less than 1 cm during touchdown phases.
