I tried to adhere to the KISS principle and I hope I succeeded. Moving to the Ejection Angle to Inner Planet's clock, your burn "from Duna" orbit, should start between 10:00 (100km) to 9:45 (500km).

To get back to Kerbin from Duna, on the center clock, you look for the colored arc that matches Duna's orbit, in this case red, and you see that "from Duna" (Duna being at 3:00) Kerbin's position should be at 5:31. Since Duna is an outer planet I switch to the small clock on the right, Inner planets on the left, and look up the Ejection Angle to Duna and see that it ranges from 5:00 to 4:45, based on a 100km to 500km Kerbin orbit respectively. So for that trip to Duna I've been wanting to make, in Map View you would line up Kerbin on 3:00 and time warp until Duna is at 1:32. It positions all departure planets at 3 o'clock and gives you the destination planet as would be positioned on a clock. So I came up with the KSP Planetary Transfer Quick Reference Chart.

I wondered, could I come up with a design for a chart, that combines all the planet's transfer windows, I could just place next to my PC as a quick reference guide. I started keeping a cheat sheet, writing down the angles but I thought wouldn't a clock reference be better? After all pilots use phrases like "He's on your 6!" or "Target a 11 o'clock! Light em up!" While it's a very handy tool, I have to minimize my game, go look on a website then get back into the game. I've been using this tool: Olex's Interactive Illustrated Interplanetary Guide and Calculator for KSP to plan my trips.

Do you just launch and hope for the best to get a return trip back to Kerbin or do you just leave the crew there and go on to a new mission? Have you ever had a time trying to figure out when the best time to make a planetary transfer would be? When is the optimum window to Duna, to Jool? Then I might finally do some manned missions. but I can rarely be bothered to wait for good alignments etc. Starting to do more complicated things like gravity assists but I still feel my ships are generally over-fueled for purpose and my trajectories are sub-optimal. the low gravity lander (inspired by Gilly) is so minimal as to be almost laughable. I already have a Rover on Laythe, and have another mission to Jool underway that aims to deliver a satellite and land two rovers, one on a high gravity moon, one on a low gravity moon.

I now kinda wanna see how low an orbit is sustainable around Gilly. you almost don't need a powered descent at all. Landing on Gilly was something of a nightmare as well, the thing has so little gravity arranging an encounter was a challenge and it turned out my lander was heavily over fueled. I have the inner system more or less done, Moho was surprisingly difficult to get near but a ton of DeltaV later I got there. My current goal is to land a rover on + get a satellite in orbit around all the bodies of the solar system. Well, I've been having lots of fun on KSP and dare I say it I think I'm getting the hang of it now.
