Abstract: This paper globally optimized the 4-D flight trajectories between the Mars and the Earth by using a combined optimization algorithm. The optimization algorithm is comprised of static parameters and dynamic control laws. The optimal program of the 4-D flight trajectory between the Mars and the Earth is obtained by a great deal of flight numerical simulation. The numerical simulation re-sults show that this combined optimization algorithm is very useful regarding on global and inte-grative optimization of both flight trajectory and all design parameters.
