Otherwise, start when you are farthest from Kerbin. That means that if you are orbiting the same way as Mun orbits Kerbin, start when you are between Mun and Kerbin.

Begin burning your thrusters prograde when you are moving opposite to Mun.

Start the trip back to Kerbin by burning your thrusters until you reach a 200 km orbit around Mun.Lower your landing gear at 2,000 m and kill any remaining horizontal velocity you have, then approach the Mun’s surface at 6 m/s or less.Decrease the velocity below 10 m/s by the 10,000 m mark.Your velocity should be between 300 and 400 m/s at that point. Start slowing down by applying downward thrust at 50 km (50,000 m).

Eject the middle and lower stages if you have not done so already. Remove any horizontal velocity by applying thrust until the yellow marker is on the Navball’s top. Pick a spot to touch down, then begin the descent.Once you have reached Mun, apply retroactive thrust to move into a Munar orbit below 200 km.You can widen the apoapsis a bit over Mun to get better odds of getting caught in its gravity field.Use the time warp to pass the time after you have a correct path set. Keep in mind that you are going for an extremely wide orbit, and only your apoapsis needs to reach the Mun. Once Mun rises on the horizon, begin a forward burn to widen your apoapsis until it reaches Mun’s orbit.Maintain free flight in Kerbin orbit, keeping an eye on the horizon.

If you can not reach orbit at this stage, add more fuel to the rocket’s lower stage.

That means you have to get your orbit periapsis and apoapsis to be the same. Circularize your orbit between 70 and 150 km.You need to start tilting your spacecraft 10 degrees east (to achieve the same orbital direction as Mun) at around 100 m/s. Launch the rocket and begin moving towards a stable orbit.
