Path: Orbit/Interplanetary
% Double rendezvous problem between two planets. Go from one planet1 to planet2, wait some days, then come back. The DVs are assumed to be impulsive. A simple search for a start date is performed to look for the minimum outbound DV given the selected transfer time. Longer transfer times result in smaller delta-v with an optimum at the equivalent Hohmann transfer. If the transfer time is too short for an elliptical transfer the function will produce a warning.
