Considering that the solar sail spacecraft working in the Lissajous orbit will be affected by the shadow of the earth or the solar wind, which sometime makes the spacecraft unable to work, we try to use the solar light pressure as the thrust to carry out the Lissajous orbit transfer in advance. Because the solar pressure parameters(cone angle, clock angle and solar pressure factor) will change the position of the libration points, we propose the idea of splicing the old and new libration point manifolds to transfer the escape spacecraft to the new Lissajous orbit to achieve orbit maintenance. The simulation results show that besides changing the cone angle and the solar pressure factor, the clock angle can also achieve orbit transfer, and the influence of the solar pressure factor on the periodic orbit is greater than the other two. This study provides a reference for the solar sail spacecraft in the aspects of periodic orbit transfer, orbit maintenance and avoidance of the earth's shadows.

Transfer Trajectories

This paper investigates the trajectory design issue for the transfer from the Lissajous orbit of CHANGE 2 probe to asteroids. First, an intersection search method, which is a general design method of low-energy transfer trajectories by searching the intersection of unstable and stable manifolds in the circular restricted three-body problem (CRTBP), is applied to produce the zero-cost flyby trajectories for the asteroid flyby missions of CHANGE 2 probe, and the simulation result shows that this method is invalid. Then, for this trajectories design issue, a perturbation method, which consists of a process of searching initial trajectories by applying velocity perturbations in the direction of unstable eigenvectors of the Lissajous orbit and a trajectory correction process with two-level differential correction, is proposed. Finally, the transfer opportunities between the Lissajous orbit of CHANGE 2 and asteroids Toutatis and 2010 JK1 are searched by the perturbation method. The results show that the method proposed in this paper can identify low-energy transfer trajectories for asteroid flyby missions of CHANGE 2. Moreover, this method provides a global understanding of the trend of impulsive maneuvers over the transfer date.
