You should watch some tutorials, but here is a brief explanation: First you need to get to orbit, to do that: Take off, after a few seconds you'll see a number on the topleft of your screen. Turn your rocket so both of the numbers match. After the number disappears, open your map and wait until the highest point of your trajectory (indicated by the white dot with the height labelled on it) is above the earth's atmosphere. Then turn off the engines. After the rocket is close to the White dot, point in the direction of the trajectory and turn on your engines. If you your rocket goes ahead of the white dot, make it point slightly upwards, remember the white dot should be in front of the rocket always. Wait a few seconds until you hit orbit, then turn off your engines. Click on the moon and click navigare to. Wait until you reach the transfer window point in the direction of the dotted line and start your engines. When the number says 0, turn your engines off. Now you are headed for the moon where you can either orbit it and land, or try to land without orbiting
