There&#x27;s no need for a supercomputer. :) Trajectory calculations of that sort are relatively routine, even including the use of ion propulsion, and can be run on a desktop in a reasonable amount of time. (Not to say you can&#x27;t come up with trajectory calculations that wouldn&#x27;t benefit from a big cluster, though.)<p>Also, the computer in the movie was Pleiades at NASA Ames.
