Apollo Redux
The Lunar Reconnaissance Orbiter has photographed Apollo landing sites. These aren't even at the full resolution that the LRO's imaging system is capable of, but clearly show LEM descent modules, scientific instruments, and even, in one case, a trail left by the astronauts. First time these sites have been seen in forty years, and a fine reminder that the moonlandings we're celebrating actually happened and left artifacts that may, in the Lunar vacuum, last hundreds of thousands of years.
