Topic: The role of impact processes in the formation and early evolution of the Earth-Moon system
The accretion of planets and their thermochemical evolution, the formation of the Moon, cratered landscapes, and the origin of habitable environments and atmospheres, are consequences of hypervelocity collisions of asteroids and comets with planetary bodies including the Earth. Impacts may be considered as one of the most fundamental processes in the solar system.
A key question is whether stochastic impacts of large bodies (giant collisions) may have significantly changed the course of the evolution of individual planets or whether the evolution of planets was more or less determined after its formation.
The presentation comprises examples of multi-scale numerical modelling, laboratory impact experiments, and morphological and geophysical observations on the Moon to disentangle the collision history of the inner solar system and to quantify the role of impacts in the formation and early evolution of the Earth-Moon system.
