Abstract
This paper presents reconstruction of Voyager 2 trajectory to examine how the mission was optimised for fuel and Time of Flight(TOF), as well as to find out if there is a more efficient trajectory for the full Earth-Jupiter-Saturn-Uranus-Neptune (EJSUN) sequence. Variable TOFs between each interplanetary maneuver for launch dates ± 1 year from the original were considered. Brute force search algorithms were developed to find optimized trajectories, the solution to Lambert’s problem for fast computation, and a patched conic integrator to plot the optimal trajectories. Multiple ‘unpowered’ gravity assist trajectories were found: the minimum total change in velocity (ΔV) at perigee found was less than 0.0035km/s for a total TOF of 4978 days (13.64 years), the shortest TOF trajectory found spanned 3299 days (9.04 years), with a total ΔV at perigee requirement less than 0.11km/s. With consideration to the trajectories found, it was determined that the Voyager 2 trajectory was likely to have been optimized for TOF.
