This is why I come to letsrun, all the cutting edge science. I could read about science at nasa or some shi7, but those guys are years behind. Anyways, gettting a solar powered helicopter to the moon should be a relatively simple matter. The earth is moving right? And the moon is moving right? All you have to do is get the helicopter to hover in place in the path of the moon's orbit, should be easy with solar power. The force of gravity operates at the same speed as the force of light, so using its solar motor the helicopter can propel itself opposite the earth's gravity at the same speed, hovering. The earth will move away from the helicopter and when it gets into the path of the moon's orbit, in the moon's gravitational field, the moon will scoop it right up. Its just a matter of using light rays to hover down at this point.
