Collisions among small bodies, on planetary surfaces and with atmospheres (meteors)

This session welcomes contributions on laboratory impact experiments and theoretical modelling of impacts; planetary space missions which, by imaging small bodies and planetary satellites surfaces, allow the investigation of the outcome of collisional events (Rosetta, New Horizons, OSIRIS-REx, Hayabusa2, Dawn); 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.

Contributions related to the latest observational and modelling techniques applied to meteor science will be also included. This session will discuss recent results in recording meteor activity and modelling the process of ablation enabling the direct measurement of the flux of small planetary impactors.
