The search for organic relics from the early Mars is one of the major science objectives of the next missions to Mars: NASA MSL 2011 and ESA ExoMars 2018. To fulfill these mission goals, the MOMIE project has been developed to study the processes which potentially drive the evolution of organics, and evaluate the stability of organic molecules under current environmental conditions at the Mars surface. An experimental set-up enabling to simulate various interactions encountered by organic matter on Mars is the heart of the project. For instance, the relative influence of hydrogen peroxide (H2O2) diffusion in the soil and of oxidants formed by UV-water ice or UV-minerals interactions can be studied by monitoring an organic sample with infrared spectroscopy. The more complex synergy of different processes will be the UV irradiation of an organic compound adsorbed on a mineral matrix in contact with water ice and/or oxidants.
