The primary aim of Hayabusa mission is to reveal the relationship between asteroids and meteorites, including a fundamental question whether the asteroids are the parent body of meteorites or not. The XRS (X-Ray Spectrometer) onboard Hayabusa observed X-ray fluorescence emission from the uppermost surface materials of Itokawa, excited by solar X-rays, in order to determine the major elemental composition of Itokawa. The results of analysis indicate that major elemental composition of the surface materials of Itokawa resembles that of chondrite-analogues. In particular, elemental mass ratio of Fe/Si is larger than that of average composition of ordinary chondrites but the corrected result with mineral mixing effect indicates that the Fe/Si ratio is nearly equal to that of average ratio of ordinary chondrites. Since metallic Fe-rich meteorites are ruled out in the candidates of meteorite-analogues of Itokawa in terms of an S (4) subtype asteroids (Gaffey et al., 1993), our result may support that the reason of reddened and darkened features in visible and near infrared reflectance spectrum is space weathering.", "subitem_description_type": "Other"}]}, "item_5_description_32": {"attribute_name": "資料番号",

内容記述 | The Japanese Hayabusa (MUSES-C: Asteroid Sample-return Spacecraft) spacecraft successfully carried out in situ observations of S (4) asteroid 25143 Itokawa. The primary aim of Hayabusa mission is to reveal the relationship between asteroids and meteorites, including a fundamental question whether the asteroids are the parent body of meteorites or not. The XRS (X-Ray Spectrometer) onboard Hayabusa observed X-ray fluorescence emission from the uppermost surface materials of Itokawa, excited by solar X-rays, in order to determine the major elemental composition of Itokawa. The results of analysis indicate that major elemental composition of the surface materials of Itokawa resembles that of chondrite-analogues. In particular, elemental mass ratio of Fe/Si is larger than that of average composition of ordinary chondrites but the corrected result with mineral mixing effect indicates that the Fe/Si ratio is nearly equal to that of average ratio of ordinary chondrites. Since metallic Fe-rich meteorites are ruled out in the candidates of meteorite-analogues of Itokawa in terms of an S (4) subtype asteroids (Gaffey et al., 1993), our result may support that the reason of reddened and darkened features in visible and near infrared reflectance spectrum is space weathering. | |||||
