The study of the small bodies of our solar system provides information about its early history, more than 4.5 billion years ago. The study of larger, differentiated bodies (i.e., with a metallic core and a rocky mantle like Mars, the Moon and the Earth) provides information about their internal structure and their geologic history.
Our approach is based on the study of a variety of objects:
- meteorites and micrometeorites (including their collection in the field)
- returned samples from space missions
- terrestrial impact craters and their ejectas (impact glasses in particular)
