Mining asteroids seems so absurd. Why not mine the Moon like others have done before.

The CCD stereo camera on board China's Chang'e-2 lunar probe has a resolution 17 times higher than the camera carried by Chang'e-1. To complete the pathfinding mission, Chang'e-2 will now get even closer to the moon, orbiting as low as 15 kilometers above the surface. In this special low orbit, Chang'e-2 will continue its high precision mapping, down to a resolution of just one meter. It will focus on specific areas, to prepare for the lunar touch down of Chang'e-3, scheduled in 2013.
