Scope Dynamic studies of rotational motions of celestial bodies give the important key to understanding of their internal structure, gravitational fields and dynamics of their shells. Due to recent space missions and precise radar and laser observations from the Earth, the extremely important data on rotational motions of Mercury, the Moon, Mars, the Titan and other bodies of solar system were obtained. Further improvement of accuracy in observations of rotation of Mercury and the Moon is expected in the near future. Rotations and internal structures of solar system bodies have general potential to find out also the important specific features (resonant character of motion, presence of a liquid core, presence of liquid ocean shells, a massive atmosphere at the resonant satellite of the Titan and others). These features of celestial bodies result in necessity of development of new approaches and new methods for construction of analytical theories of their rotation. The basic purpose of this session is to combine and systematize studies of rotational motions of solar system bodies in view of their multilayered structure for the Earth, Mars and the Moon as the first step. Researches on gravitational fields and internal structures of solar system bodies, and construction of their models. Studies of tidal evolution of the rotational motions etc. Researches of rotational motions of the Earth and Mars as systems of interacting shells (solid core, liquid core, mantle). New methods of study of rotational motion of the Moon. Dynamics of relative oscillations of the shells in celestial bodies (differential rotations and small translational relative displacements) and their reflections in variations of endogenous activity of planets and satellites. Studies of correlations of the rotational dynamics with natural processes of solar system bodies, their energy, space-temporal regularities in the changes of activity of the processes, and their mechanisms.
