I'm tossing around the idea of doing an opposition class Duna mission instead of the standard kerbal way of "wait for the launch window then wait a year for the next one". There are two parts to this question: When do I need to depart from Kerbin and later on Duna? How much delta-v would be required to depart, insert into Duna orbit, then return to Kerbin? Thanks in advance!
