The on-going missions to small bodies have provided invaluable observations regarding the properties of primitive small body surfaces in different places of the Solar System, their cratering record, as well as the signatures of other processes (e.g. thermal).
The aim of this session is to open the discussion regarding the impact process on small body surfaces, the role of their physical properties and in particular their surface materials. We welcome contributions regarding:
- Studies on the latest advances in observational (e.g. spectroscopy) and experimental techniques (e.g. production of analogue materials) to characterise small bodies and their surface materials.
- Studies on laboratory impact experiments and theoretical modelling of impacts; planetary space missions which, by imaging small bodies and other planetary surfaces, allow the investigation of the outcome of collisional events (Rosetta, New Horizons, Dawn, Hayabusa2 and OSIRIS-REx); asteroid families that are consequence of the collisional break-up of their parent bodies; collisions among asteroids of different compositions that can lead to surface contamination and material mixing. Observational and experimental studies on other processes that occur on the surfaces of small bodies such as thermal cycling etc.
