Scientific paper

One of primary goals of the Solar System Exploration Program is to determine how planets and small bodies evolved. Phobos and Deimos from a technical point of view are more accessible as the targets for space exploration than most of the small bodies. There is a need to understand the basic scientific nature of the Martian moons, both as representatives of the family of Small Bodies in the Solar System and as components of the Mars planet system. There are a number of key unresolved scientific problems related to the Mars, Phobos, and Deimos (MPD) system. The main one being the problem of origin and evolution of the MPD system, solution of which requires knowledge of the chemical composition of Martian moons, impact history and surface morphology, internal structure etc. This investigation fits into the Mars Exploration Program, as the moons are part of the entire Mars system. Study of the fundamental physical and chemical state of Phobos and Deimos will provide information required for understanding the origin and evolution of the Martian planetary system. In spite of previous efforts, their composition, internal structure and details of the processes, which produce their surface morphology, are poorly understood. Because of this, the models of their origins are not well constrained. Missions to Phobos and Deimos with the appropriate instrumentation would be capable of addressing the unresolved issues. Thus the main scientific goal of a Phobos/Deimos mission is to study the different characteristics of the Martian satellites, and understand their origin and evolution.
