  1. Modelling Multi-Objective Trajectory Optimisation ESR: Elisabetta Iorfida Supervisors: Prof Phil Palmer, Prof Mark Roberts Surrey Space Centre, University of Surrey, UK First Astronet-II Training School Rome "Tor Vergata" University – 14th-17th January 2013

  2. Personal Background First Astronet-II Training School Rome "Tor Vergata" University – 14th-17th January 2013

  3. Personal Background • project (TU Delft Astrodynamics toolbox) • Delft University of Technology “Tudat: a modular and robust astrodynamics Toolbox” 5thICATT 2012, International Conference on Astrodynamics Tools and Techniques, 29 May – 1 June 2012, ESA/ESTEC, Noordwijk, The Netherlands First Astronet-II Training School Rome "Tor Vergata" University – 14th-17th January 2013

  4. ESR Project Messenger mission • PROs • Complex scenario, commonly used to optimise the mission. • CONs • Difficult to be modeled; • Solution search space complexity increases. • PhD Researcher • Surrey Space Centre, University of Surrey (April 2012 – Present) First Astronet-II Training School Rome "Tor Vergata" University – 14th-17th January 2013

  5. ESR Project General outline of the project • 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 • Mid-course impulse optimisation methods • Variational analysis approach Current state of the art Future work First Astronet-II Training School Rome "Tor Vergata" University – 14th-17th January 2013
