Scanning electron images of Hayabusa particle RB-QD04-0042. (a) Backscatter electron image of the particle as received, resting in a pit of the transport glass slide. The grain consists of olivine (Ol) with a troilite (Tro)-tetrataenite (T-Tae) aggregate on its upper right side (bright); fine-grained material on the surface represents loose olivine particles. (b) Secondary electron image of the particle after mounting on the Al stub. The locations of FIB sections are marked. Notably, the grain shows a highly fractured region on the right side.
