This paper presents investigations to generate control schemes during atmospheric of aerubraking for Mars mission. The complete mission consists of a deorbit phase, an atmospheric phase, and a reorbit phase. The atmospheric maneuver is composed of an entry mode, a cruise mode, and finally an exit mode. During the cruise mode, constant altitude and velocity are maintained by malls of bank angle control with constant thrust or thrust control with constant bank angle. Typical results are given for the application of aerobraking to orbital plane change. Comparisons between these two control schemes bring out some interesting features.
