Our group is involved in past, current and future remote-sensing instruments onboard several spacecraft missions exploring Mars (IMP, HiRISE, CRISM, CaSSIS), Titan (DISR), comets (HMC, OSIRIS), Mercury (BELA), Europa and Ganymede (GALA). We analyse data and select targets for future observations. Using multiple datasets, we study the influence of water and ices on the evolution of the martian surface, the dynamic surfaces of comets and we are preparing to analyse altimeter data of Mercury surface.
