Prospects of photogravitational celestial mechanics for space systems control

The possibilities and prospects of a solar sail using to solve new problems of space systems control are discussed. The economic and environmental benefits that can be obtained with this control method for interplanetary transitions or for the functioning of the space system in the near-planetary space are considered. This type of control is carried out through the use of special solar sail designs that allow the maximum use of light pressure. The very idea of the solar sail control is connected with the search for new ways to use solar energy, as well as with the expansion of the nanotechnology application field on Earth and in space. When designing the solar sail, the possibility is immediately taken into account that when it is deployed to its working position in orbit, it will be used to control the spacecraft during flight. At the same time, the question of the physical and optical properties of the real sail in space conditions is extremely important. The use of new technologies to significantly improve such properties should contribute to the prospect of the solar sail possible use as a space engine based on the direct use of an unlimited solar radiation energy source.
