Well depending upon the camera they have on-board, and how close
they fly to the surface, they can resolve down to about 50 cm.
Being outside the Earths atmosphere, spacecraft can map the Moon
in many different wavebands and colours e.g. from X-rays, through ultra-violet
and visible light, right up into thermal infrared.
Spacecraft can also map the Moon using RADAR in order to see what
is beneath the surface.
