On-Orbit Servicing (OOS) is the process of improving a space-based capability through a combination of in-orbit activities. With the successful completion of the OOS enabling technologies, the mission planning problem is issued, optimizing mission sequences and trajectories for Servicing Spacecraft (SSc) servicing multiple targets. During the mission process, even though the adequate preparations were done, some accidents may still occur, e.g. the user adds some unassigned targets in emergency, or one of the SScs malfunctions and the un-completed targets should be re-allocated. Then it is necessary to reschedule the existing mission scheme, regenerating a new mission scheme to deal with the new-arrival targets, minimizing the disturbances on the initial mission scheme, minimizing the total rendezvous cost increment, and at the same time designing the rendezvous trajectories. The OOS mission rescheduling problem for coplanar circular constellation is studied in this paper. The reschedule model is developed first. Then base on the Squeaky-Wheel Optimization framework, a general optimization framework for combinatorial optimization problems, the solution method is proposed. Numerical simulations are carried out to demonstrate the effectiveness of the model and rescheduling method.
