Description:
The near-infrared spectrometer on board the Japanese Hayabusa spacecraft found a variation of more than 10% in albedo and absorption band depth in the surface reflectance of asteroid 25143 Itokawa. Spectral shape over the 1-micrometer absorption band indicates that the surface of this body has an olivine-rich mineral assemblage potentially similar to that of LL5 or LL6 chondrites. Diversity in the physical condition of Itokawa's surface appears to be larger than for other S-type asteroids previously explored by spacecraft, such as 433 Eros.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Abe, M -- Takagi, Y -- Kitazato, K -- Abe, S -- Hiroi, T -- Vilas, F -- Clark, B E -- Abell, P A -- Lederer, S M -- Jarvis, K S -- Nimura, T -- Ueda, Y -- Fujiwara, A -- New York, N.Y. -- Science. 2006 Jun 2;312(5778):1334-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency, 3-1-1 Yoshinodai, Sagamihara, Kanagawa 229-8510, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16741108" target="_blank"〉PubMed〈/a〉
