Caption: Figure 21.
Example of a disrupted boulder on Bennu located at the center of a 128 m diameter crater (21N, 189E). (a) The OLA v21 shape model of Bennu (M. G. Daly et al. 2020), with the global basemap projected onto the surface (C. A. Bennett et al. 2021). The 128 m diameter crater is outlined in magenta. (b) Close-up of the crater. The yellow square highlights the region of the disrupted boulder that is shown in more detail in panel (c). (c) PolyCam image of the disrupted boulder, identified by the radial concentric throughgoing fracture pattern. (d) OLA digital terrain model of panel (c), revealing a central pit (red is the lowest point) at the point of origin of the radial fractures. Pink arrows in panels (c) and (d) highlight the same fragments.
