I have a craft that\'s very near the fuel limit for getting to the mun and back, I just need to eek out a little more efficiency, so what\'s the optimal route? As it is, I head towards 90 when I get over 12kish m and I am at full 90 at around 50k. I set up for the minimal possible periapsis at 70k, and then burn for the mun when I see it rise. I end up on a direct landing path to the mun, I don\'t go into orbit around it first, and then I do a full burn around 20-25k up from the surface of the mun (which bring me VERY near to the surface), and then do a slow decent. Now is there a more fuel effecient way to do it? Is a longer, slower burn to slow down on the moon landing better than a full burn? Anything I should be doing differently? Is there a way of taking off from the moon that guarantees that I don\'t have to retroburn to hit Kerbin?
