It's more efficient to transfer orbits when in a low circular orbit? I assumed it would be easiest in a high elliptical orbit because you have to fight less of the origin celestial body's gravity at a distance. EDIT: Hrmm I still can't get to the Munar surface, it blows my mind you guys could get to minimus and back with that fuel. Whatever I try its about 800 delta v to get from Kerbin orbit to munar orbit, and is usually a 50 second-ish burn (which is like half my lunar lander fuel). I also use the entirety of the booster to get to about 100,000m. Where's my waste at?
