Yes, I\'ve done this successfully a number of times, looking at the map and adding throttle until the orbit apogee stretches to the Mun\'s orbit, but using the map is too easy! I\'d like to try how it\'s done using the calculator (i.e. timing the orbit and accelerating to the determined velocity) which is more like how it\'s done in the real world. (I know, calculating is so not Kerbal!) Anyway, I did find that eyeballing the map works quite well (Apollo astronauts had little more than window sights for alignment too!): 1. Press TAB to focus on Kerbin 2. Zoom to fill the screen with the globe of the planet 3. Align the view so the Mun icon sits at the bottom of the planet (behind it) Assuming you have a nice round equatorial orbit (I tried this with 100km), your craft will point to the top of the planet when it passes in front. This is conjunction. For opposition, your craft will pass behind Kerbin, and you can spot when it passes the Mun, about a quarter of the way from the bottom of the planet\'s globe. Agreed, maybe a measuring tool or something!
