Regolith particles on the asteroid Itokawa were recovered by the Hayabusa mission. Their three-dimensional (3D) structure and other properties, revealed by x-ray microtomography, provide information on regolith formation. Modal abundances of minerals, bulk density (3.4 grams per cubic centimeter), and the 3D textures indicate that the particles represent a(More)
Three-dimensional (3D) imaging techniques, such as x-ray computed tomography (XCT), serial sectioning method, transmission electron microtomography (TEMT) and 3D atom probe (3DAP), provides 3D internal structures and external form of objects. In order to obtain the 3D images of one object from the synchrotron-XCT (SR-XCT), FIB-SEM serial sectioning, TEMT(More)
