If anyone feels like planning a trajectory like Rosetta's or, more precisely, writing a computer program to plan a trajectory, ESA's Global Trajectory Optimization [0] contest is for you. It's dubbed the "America’s cup of rocket science". The past contests and their entries are quite interesting, ranging from mapping the whole surface of the Galilean moons of Jupiter (Io, Ganymede, Callisto, Europa) or doing an asteroid hopping mission in the main asteroid belt. I might participate in the next one. [0] http://sophia.estec.esa.int/gtoc_portal/ http://sophia.estec.esa.int/gtoc_portal/
