Messenger missionPROs
• Complex scenario, commonly used to optimise the mission.
CONs
• Difficult to be modeled;
• Solution search space complexity increases.

• Multi-objective interplanetary trajectory optimisation• Modelling of science return and cost functions (2 and
3 body problems)• Robustness of mission designs
• Non-linearized solutions • Complex scenarios, e.g. addition of fly-bys• Pareto front solutions
General outline of the project
Current stateof the art
• Mid-course impulse optimisation methods• Variational analysis approach
Futurework
