In this dissertation, the design and optimization of lunar probe orbit has been studied by using the theory and method of spacecraft orbital dynamics, aiming at to launch polar moon satellite from the earth parking orbit, and considering synthetically the problems about the launcher energy, flying time, launch window and orbit navigation. The flying conditions, program and orbit of the lunar probe are given.
