The Mars Science and Exploration Session will address the latest results on the interior, surface, atmosphere and ionosphere of Mars from recent and ongoing Mars missions, such as Mars Global Surveyor, Mars Express, Mars Odyssey, Mars Reconnaissance Orbiter, MERs, and Phoenix, as well as the future exploration of the Red Planet. In particular, the session is primarily targeted at: (1) presentations on scientific investigations as well as theoretical models concerning the deep interior and subsurface structure; the surface morphology, geology, geochemistry and mineralogy; the atmospheric composition, dynamics and climate; the ionospheric environment and its interaction with the solar wind; Phobos, water evolution, astrobiology and habitability of Mars; (2) discussions on scientific goals, long-term plans and proposed experiments for future robotic and human missions to Mars, as well as results obtained from ground-based measurements. Both broad solicited talks and contributed presentations will be included in the program.
