The Lunar Reconnaissance Orbiter which entered lunar orbit a few weeks ago, has imaged five out of the six Apollo landing sites. Which was a tad earlier than I was expecting. They were taken when the Sun was low in the sky so the decent stage of the lunar module would cast a long shadow to make them easier to spot.

Anyway check this out:

When it enters its lower mapping orbit, the images will get even better with two or three times the resolution.
