• Early solar system processes: origin and early evolution of terrestrial planets and meteorite parent bodies.

Important questions regarding the origin of the terrestrial planets and their building blocks are still open. Are primitive meteorites in our collections really the building blocks of Earth and other terrestrial planets? What processes are responsible for the depletion of volatile elements in the inner solar system? What is the origin and budget of volatile elements in the terrestrial planets? How much of the original volatile budget is lost during planetary growth? What can the Moon tell us about the early history of the Earth? Were the terrestrial planets affected by a “late heavy bombardment” of smaller bodies?

Chemical and isotopic studies of meteorites and lunar samples from the Apollo missions provide new constraints. This topic is closely related to research in TRR 170.
