Abstract

The near-infrared spectrometer (NIRS) on the Hayabusa spacecraft obtained spatially resolved reflectance spectra of 25143 Itokawa between September 12 and November 24, 2005. In this study, we had modeled a photometric function of the asteroid surface based on the observed spectral data and have investigated the surface heterogeneity of asteroid Itokawa.
