Carbon Across the Solar System

Session ID#: 162387

Session Description:
Studies of the existence and state of carbonaceous material on Solar System bodies is at the forefront of planetary research. Results from studies of samples of low-albedo asteroid 162173 Ryugu from the Hayabusa2 probe are being shared and discussed. The OSIRIS-REx space probe has retrieved samples from low-albedo asteroid 101955 Bennu. As a framework for these studies, telescopic, laboratory and theoretical studies of carbon in all its forms have recently snowballed. The 2018 SSERVI Carbon in the Solar System workshop launched a series of presentations and discussions at various venues, enabling an information exchange around the weathering of carbonaceous compounds in response to thermal processes and irradiation, and what implications these compositions have for understanding material processing in the Solar System. We will generate and share ideas to support research of the new samples, along with studies of carbon, in various forms, at other locations across the solar system.
