Hmm, i may be getting confused with the terms here, but i thought direct ascent meant having one continuous burn from launch to get you to your destination. What i'm describing involves being in an orbit, then doing the burn to put you in a transfer orbit into the target body's SOI. I thought that was how most people get to the Mun? I've never seen anyone get to the apoapsis of their transfer orbit then burn to put themselves into the same orbit as the Mun... am i missing something here?
