I\'m aware there are many threads on this, reason i\'m making a new one is i can\'t understand what those are saying. What is an eastward orbit ? An orbit is either clock-wise or counter clock-wise. Anyway, so here\'s my situation, tell me what i\'m doing wrong I land on the mun with half a tank of fuel and 3 quarters of RCS left. I usually manage to land close to the the equator. I make a counter-clockwise orbit, i adjust the orbit so the Ap faces towards kerbin, I boost at the Pe so Ap is closer to kerbin (i\'ve tried various Ap distances and angles). Every time I end up orbiting kerbin with huge Ap and Pe values (last time it was 6million to 21 million) and i simply don\'t have enough fuel to correct that. What can i do to end up with a smaller Ap value ? Should I make a clockwise orbit instead ? What should my TKI orbit look like ? Any pictures or a video would be appreciated. If you\'re going to describe it could you tell me what should the Ap and Pe values be and what should be the angle between |Ap Pe| and |kerbin mun| given |Ap Pe| is on the same plane as |Ap Pe| Thanks in advance
