The way I typically get back: 1. Get into the Mun\'s orbit with my ascent stage 2. Change my apoapsis so that it is the opposite direction of the Mun\'s orbit 3. Once in Kerbin\'s SOI I deorbit and land
Why does your lander use only RCS? That\'s a little hard to land with, because it\'ll either be underpowered for braking, or overpowered for landing; depending on how far you are from the surface and how fast your falling.
I don\'t really know if this counts as a space station per-say, but my ACEV drops the Habitation/Service module into a roughly 50km Munar orbit. Undocking After thrusting away with RCS.
