And we paid attention to Hayabusa (MUSES-C: Asteroid Sample-return Spacecraft)/XRS (X-Ray Spectrometer) thermometer observations by means of determining the surface conditions of Itokawa. This thermometer was attached to measure the temperature of Hood by which the detectors of XRS were cooled radiatively. Since it was calibrated sufficiently in the thermal vacuum test, we found it is useful to investigate the surface thermal properties of Itokawa. We compared XRS temperature calculated with thermal model with those derived from XRS thermometer observations and made attempt to find the most suitable thermal property of Itokawa., 資料番号: AA0063505021}, pages = {82--85}, 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 = {Thermal-inertia estimation of asteroid 25143 Itokawa with Hayabusa/XRS thermometer}, year = {2006} }
