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, 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 and composition; the surface morphology and composition; 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 missions to Mars, as well as results obtained from ground-based measurements. The session includes also a small subsession of a community effort for a receiving and curation facility of Mars Sample Return. Both broad solicited talks and contributed presentations will be included in the program.
