**3.4 Photogravitational celestial mechanics in the solar system**

(objects of research—objects of high windage)

1.Natural small bodies in the solar photogravitational field.

	- a. Controlled flights of spacecraft with low thrust of the solar sail. Closed interplanetary flights with a sail, near-solar maneuvers.
	- b. Near-planetary and circumsolar gravity-assist maneuvers with a solar sail.
	- c. Orbit correction (satellite retention in Geo Stationary Orbit).
	- d. Rotational movements: 3-axis stabilization, orientation, and control in space under the influence of the moment of radiation pressure forces.
	- e. A solar sail as an element of a cable system for transporting a dangerous asteroid from orbit.
