Abstract
To search the problem of launch opportunity for interplanetary exploration, especially large-scale search of launch opportunity, a hybrid search method is presented. According to the requirements of exploration mission, it defines the target function and makes certain search domain. It reduces the search dimension, combining Lambert theory and Gauss algorithm, and solves this problem using the hybrid method. Compared with traditional method, the method proposed needs less computational time and is more efficient. Finally, taking the asteroid Ivar (numbered 1627) rendezvous mission as example, the results of methods are verified and investigated.
