3rd Global Trajectory Optimisation Competition

Problem Definition

The proposed mission is a multiple near-Earth asteroid (NEA) rendezvous with return to the Earth. The spacecraft employs electric propulsion. Gravity assist(s) from the Earth may be exploited. The spacecraft launches from Earth, must rendezvous with three asteroids from a specified group of NEAs and finally rendezvous with the Earth, within ten years from departure. The performance index to be maximized is a function of the final mass and the stay-time on the asteroids.
