Suppose the moon has a radius of r miles and a payload weighs p pounds at the surface of the moon (at a distance of r miles from the center of the moon). When the payload is x miles from the center of the moon (x ≥ r), the force required to overcome the gravitational attraction between the moon and the payload is given by the following relation:.
