Abstract: Tether control of the momentum exchange tether assisted interplanetary orbital capture in deep space exploration was studied. Firstly, the dynamic model of a detector system in a hyper bolic flying orbit was established. Secondly,the consistent condition of orbital capture and the optimum tether cut off point were derived to analyze the dynamic characteristics.Finally, considering the sub detectors post capture orbit maneuver requirements and limitation of the tether deployment/retrieval velocity, a new optimal control problem was proposed and numerically solved by the simulated annealing algorithm.Simulation results show that the tether orientation is appropriate at the cut off point and will be beneficial for the following orbit maneuver,and the  maximum tether deployment/retrieval velocity is about 30m/s.
