Although there are evidences of relationships between the most primitive bodies of the solar system and differentiated planetary bodies with a metallic core, no sample has been found up to now that bears information on the onset of planetary differentiation. Researchers have recently described a volcanic rock produced by extremely limited partial melting of a parent body chemically similar to the most primitive meteorites (carbonaceous chondrites) and crystallized upon ascent toward the surface of the body. This sample proves that some carbonaceous bodies from the outer solar system are partially differentiated and is the missing link in a continuum between comets and iron meteorites from metallic planetary cores.

One and a half year after its launch in October 2018, the BepiColombo spacecraft has performed an Earth flyby on April 10, 2020, so as to reach Venus on its way to an orbital insertion around Mercury end of 2025. BepiColombo is the first European mission using ionic propulsion, which makes it possible to implement major changes in the trajectory with a limited impact on the mass budget.
