Imaging Science, OCAMS and Bennu
Modern planetary imagers operate at ever-greater resolution, throughput and data loading. Their scientific goals remain the same: 1) reveal new solar system phenomenon, 2) document the visual history of its surfaces and 3) provide a context for physical and chemical anyalysis of meteorites and in situ samples. The trio of imagers in the OSIRIS-REx Camera Suite-OCAMS-are reviewed from that point of view. OCAMS' expected scientific return is discussed while noting the suite's critical function as a mission system to enable the selection of a primary sample site. In addition, Bennu's status as a microgravity object is emphasized. It will serve as a high-fidelity and readily observable physical analog to the many million billion planetesimals that contributed to the formation of the planets and that, directly or indirectly, currently populate the Kuiper Belt, Oort Cloud, Jovian Trojan points and, perhaps, the Main Belt and Near-Earth Asteroid populations.
