The goals of the workshop are to integrate the main results of both the recent Earth-based observations and the missions to Mars (MarsExpress, Mars Reconnaissance Orbiter, Phoenix and Mars Exploration Rovers) into a new global picture of Mars evolution. With the same spirit of the previous workshops, discussions among scientists of different disciplines will be encouraged and it is foreseen that they will help refine the scientific goals of the future missions to Mars. This workshop is an opportunity for the young scientists to be updated on the most recent results and to be trained in some specific data processing techniques.
