On Utilization of Solar Sails in Triangular Libration Point Missions in the Earth-Moon System

In the real solar system, due to various perturbations, the triangular libration points of the earth-moon system are unstable. However, there are quasi-periodic orbits around them. These orbits show mild instability. Due to the instability, orbit control is necessary for the spacecraft around these points. In the paper, solar sails were taken to fulfill the control. Numerical simulations were made in the earth-moon system. The results showed that taking the surface area to mass ratio of the solar sail as the control parameter can achieve better results than taking the normal angles of the solar sail as the control parameter.
