The formation and evolution of silicate bodies in the solar system are at the center of our scientific questions, from asteroids to planets and their satellites, including the Earth and the Moon. Our tools are those of physics and chemistry: thermodynamics and rheology, fluid dynamics, wave propagation and transport, geochemistry and petrology. They include experimental aspects: in laboratory at high temperature, high pressure, but also numerical with the modeling of fluid flows, mineral structure, propagation and diffusion of elastic waves in complex media. Observation is another, through the deployment of seismological sensors and permanent networks. This resolutely trans-disciplinary approach aims at crossing different points of view to take a new look at geophysical and planetary objects.
