* Since the gravity is a 6th of Earth&#x27;s, launching space exploration vehicles from the Moon would be much easier and thus cheaper.<p>Could someone explain this to me? I understand launching a rocket from the Moon would be much easier than from Earth, but don&#x27;t we need to factor in the cost of getting the fuel to the Moon in the first place? Would there be any benefit over just launching a bigger rocket from earth? In this layman&#x27;s eyes, it looks like a zero-sum game.
