Dear Board,
Maybe I'm overlooking something simple, but I'm struggling to plan a Hohmann transfer between two bodies. Take, for instance, my current scenario (Uranian cargo run). I'm supposed to transfer from one moon (Miranda) to another (Titania), using a Hohmann ellipse.
This seems simple enough (burn prograde, ideally at apoapsis, until the new apoapsis is tangent to the target orbit). The problem, of course, is orbital phasing. How can I find out -- other than by endless trial and error -- the right launch window, and thus decide when to burn ? Something like a pork chop plot (https://en.wikipedia.org/wiki/Porkchop_plot), or an equivalent tool (MechJeb, anybody ?
) would help.
Of course, the problem is more general than this simple scenario, as pretty much any scenario except the "sitting duck" cases requires orbital transfer, or at least phasing... so a way to determine the best burn date would be very useful !
Thanks for help !

), and want to use just enough dV that one orbit will put the craft in phase with the target when I burn again for it.
