Extended Data Fig. 2

a, BSE image of the back face of Itokawa particle RA-QD02-0279 after Cr coating. b, BSE image of the back face of Itokawa particle RA-QD02-0279 after Ion beam Pt deposition in preparation for sample extraction for APT. The red circles indicate where the APT lift outs were extracted from the wedge. c, BSE image of the back face of Itokawa particle RA-QD02-0279 after FIB lift out. D–H) IbSE (left) and BSE images (right) of each APT needle the Cr cap is visible at the apex of each tip in the BSE images as well as the Pt weld at the base.
