Abstract: 　

  The modeling of external and internal processes, acting on the rotation of a two/tree-layer Moon, the development of the theory of physical libration of a multi-layer viscoelastic Moon with a purpose to receive the observational effects of rotational modes of two-phase core on the basis of observations planned in the Chang’E and SELENE missions form the important direction in the study of dynamics and interiors of the Solar system's bodies.

  One more problem to be considered under the Russian theoretical lunar project is the role of the resonance in the dynamical history of the Earth-Moon system. The orbital resonance acts onto the lunar rotation and onto the resonant increasing of dissipation in a lunar core and mantle due to the solar-earth tidal interaction.

1. Spin-orbital longtime evolution and physical libration of the multilayered Moon: a) construction of the analytical theory of rotation of the two / three-layer Moon and reception on its basis of physical libration tables for their application at processing precision supervisions; construction of a lunar annual almanac. b) The analysis of spin - orbital evolution of the early Moon, an estimation of internal energy dissipation, modeling of the long-term mechanism of maintenance free librations the Moon.

2. Geodynamics of a lunar core: a) the analysis of differentiation of a lunar core, detailed elaboration of plume-tectonics of a mantle and a core of the early Moon, evolution of a boundary layer a core - mantle, reconstruction of gravitational and viscous - mechanical interaction of a lunar core and a mantle, resonant dissipation of internal energy, calculation free and forced nutations a lunar core, free fluctuations of lunar core – mantle system. b) an analyses of resonant interaction of the layers of the Moon with the Earth and the Sun: possible resonance may promote an increasing of amplitudes of those terms in libration's series, which arise due to consideration of the multilayer Moon. Their detection from observations will allow estimating parameters of a lunar core. Its existence or absence is directly connected with a basic problem of an origin and of an evolution of the Earth-Moon system.

3. Spin - orbit evolution of the early Moon Reexamination of the role of the resonance in dynamical history of the Earth-Moon system. It is necessary to investigate an evolution of the Cassini's states for the orbits captured into the resonance also. A special attention will be given to the possible correlation of the resonance phenomena with physical processes, which determine the shape of the Moon, its internal structure and, consequently, its gravity field.
