So given my frustration with dealing with maneuver nodes, I've been wondering why all the guides for going to Duna or anywhere talk about building your node directly from Kerbin orbit. It seems to me, that it ought to be the same delta-V planning the route directly from Kerbin, as it would doing an escape from Kerbin, then doing the transfer after the escape. My thought process is, no matter what, you have to escape Kerbin. In fact, it doesn't even matter which direction you escape it in. You burn just prograde until you just barely get an escape. If you only burn exactly that far you resulting orbit should be almost identical to Kerbin's orbit around the Sun. From there you plan your transfer, and do another burn using the more convenient solar-level maneuver nodes. My brain tells me this SHOULD be equivalent. There will be some Delta-V negligible losses if I overshoot my Kerbin escape maybe, or escape via Kerbin's retrograde when I need a planetary prograde burn, but the first step of going anywhere is to escape Kerbin, so why not just do that first? One could argue time perhaps. If you work out the phase and such ahead of time, you wouldn't even have to sit around in space waiting for it, but most guides have you sitting in Kerbin orbit anyway. Why does it matter if my Kerbals are sitting in a convenient Solar orbit nearly identical to Kerbin orbit, or sitting in a Kerbin orbit when I start time warping to get the phase? Then again, I figure I must be wrong, and would be awesome to have someone explain why I am, because I'm not hotting the Delta-V targets on this map at all: http://wiki.kerbalspaceprogram.com/w/images/7/73/KerbinDeltaVMap.png My Kerbin escape is around 1000 Delta-V, which is close to the map, but my Duna intercept is another 1000 Delta-V, and the map says that's 100. This is hard for me to test, as I get way too frustrated trying to intercept a planet directly from Kerbin to actually see if there's a difference. Anyway, thanks ahead of time!
