You are the pilot of a lunar module sent to rescue a team of stranded astronauts from the surface of the moon. The moon is pitted with craters and there are only five flat landing pads where you can land. You have only four modules, so collisions must be avoided. Unfortunately, there is an asteroid storm going on! Your mission is to guide the module down from orbit, through the asteroids, and land safely on one of the landing pads. Then you have to take off back through the asteroids to resume your orbitting pattern. You must keep doing this until you have landed at each of the five pads. Only then can you move on to the next mission - and it'll be a tougher one!
