Fig. 2: Geological properties, craters and shape of Didymos.
From: The geology and evolution of the Near-Earth binary asteroid system (65803) Didymos
Images (a–c), geological units (c), shape (d, e), elevation (d), and crater candidates (e, f) of Didymos. a DRACO image (dart_0401929893_44497) highlights the triangular shaped ridge (yellow arrow and dashed lines), protruding boulders, boulders with north-south tracks (upper white arrow), and an area with evidence for a plausible mass movement (lower white arrow). The orange arrow indicates the location of the bright spot. b LUKE image (liciacube_luke_l2_1664234227_01003) indicates plausible corners or longitudinal N-S ridges. The solid white arrows point to 160-m and 85-m boulders. Units shown on mosaic (c; dart_0401929893_44497 and dart_0401929913_07357) may be the result of elevation changes, overlain here on the Didymos GDTM (d). Crater candidates are shown on the GDTM in (e) and (f). Consistent with (b), GDTM (f) shows some non-circular perimeter attributes when viewed from -Z pole. GDTM does not include limb data, and thus lacks the triangular outline seen in the images (a–c; see Methods).
