Optimization techniques are critical when investigating Earth to Mars trajectories since they have the potential of reducing the total ΔV of a mission. A deep space maneuver (DSM) executed during the cruise may improve a trajectory by reducing the total mission ΔV. Nonetheless, DSMs not only may improve trajectory performance (from an energetic point of view) but also open up new families of trajectories that would satisfy very specific mission requirements not achievable with ballistic trajectories. In the following pages, various specific examples showing the potential advantages of the usage of broken plane maneuvers will be introduced. These examples correspond to possible scenarios for Earth to Mars trajectories during the next decade (2010-2020).
