Star is a mission design tool that globally searches for patched-conic trajectories that satisfy a set of user-defined constraints. It has been used to develop dozens of mission concepts at the Jet Propulsion Laboratory spanning multi-target rendezvous, sample return, multiple gravity assists (ballistic, high- and low-thrust), central-body switch to escape Earth or capture at a planet, planetary moon tours, and small-body tours sequenced from a pool of thousands of candidate targets. Star exhibits polynomial algorithmic complexity by constructing trajectories from independently computed encounter times, transfer legs, and flybys. Example missions of a ballistic transfer to Titan, tour of the Trojan asteroids, and low-thrust rendezvous with Mercury demonstrate the efficacy of the tool.
