The optimization design, calculation and imitation for soft-landing orbits of Lunar probe passing through parking orbit of the moon are studied in this paper according to the theory and method of spacecraft orbital dynamics and the optimal control theory. First the basic scheme of the soft-landing orbit passing through the paring orbit is determined according to the specific practice of the moon probe engineering of American and Muscovite. Then the orbital design and imitation of the minimal energy for the limited force is studied from the perilune of the transitional orbit to the landing. At the same time, the corresponding computational method, the design cycle and some computational example are established or given. In the end, according to the appropriate parking orbit designed and the running cylinder number, subastral point trace for the last cylinder of the parking orbit is closed to the soft-landing point, and the design method, flow and computational example are given.
