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., 資料番号: AA0063505019}, pages = {73--76}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)}, title = {Morphology and color of the surface of Itokawa: Evidence for space weathering}, year = {2006} }
