OCAMS Reveals (101955) Bennu

On their way to Bennu, the OSIRIS-REx MapCam, SamCam and PolyCam imagers (Rizk et al, 2018a) have searched for Earth Trojan asteroids (Hergenrother, et al, 2017; Cambioni et al, 2018), captured portraits of the Earth and Moon during Earth flyby (https://www.nasa.gov/image-feature/from-the-earth-moon-and-beyond), recorded evident water-ice debris being shed from the OSIRIS-REx spacecraft (Rizk et al, 2018b) and revealed the size, shape and brightness of Bennu during the approach to and preliminary survey of this carbonaceous near-Earth asteroid. This presentation will present images from each of these campaigns. We will briefly describe the calibration and health of the cameras and challenges encountered while operating them, while placing their spatial and radiometric capabilities within the context of other planetary imagers.
