WebAstronomers on Earth can reflect laser beams off these mirrors and record the time it takes for the laser to return. We know how fast the laser beam is travelling (the speed of light) so we can easily calculate the distance that the laser beam has travelled. The Earth-Moon distance would then be half of this value.
