The project is part of French Research National Agency grant, and concerns the origin and chemical evolution of the extraterrestrial organic matter in past or present aqueous environments of solar system bodies. This project intends to particularly emphasize on the interaction between the organic and the inorganic parts (minerals, salts) that are coexisting on asteroids, planetary surfaces (such as Mars) or ocean floors (icy moons). Investigating the evolution of the organic matter in these aqueous conditions are essential to help their research and identification nowadays on these bodies, but also to understand what kind of molecules can be available for the emergence of living systems. This experimental work is to tackle some of the most intriguing questions around the organic matter, its preservation, complexification or destruction favor by specific conditions and/or minerals in the aqueous systems.
