Abstract

A high-resolution 3D surface model, map-projected to a digital terrain model (DTM), and precisely ortho-rectified context images(orthoimages) of MASCOT landing site area are important data sets for the scientific analysis of relevant data that have been ac-quired with MASCOT's image camera system MASCam and other instruments (e.g., the radiometer MARA and the magnetometer MASMag). We performed a stereo-photogrammetric (SPG) analysis of 1050 Hayabusa2 Optical Navigation Camera (ONC) imagesacquired during the asteroid characterization phase and the MASCOT release phase in early October 2018 to construct a photogram-metric control point network of asteroid (162173) Ryugu. We validated existing rotational parameters for Ryugu and improved thecamera orientation (position and pointing) of the ONC images to decimeter accuracy using SPG bundle block adjustment. We pro-duced a high-resolution DTM of the entire MASCOT landing site area. Finally, based on this DTM, a set of orthoimages from thehighest-resolution ONC images around MASCOT's final rest position complements the results of this analysis.
