This LRO image shows the Apollo 17 landing site, the last of the missions to land on the Moon. You can see the descent stage of the Lunar Module, and also labeled is something amazing: the flagpole placed into the lunar surface by the astronauts!

You can even see the pole's shadow. I don't think any of the original flags are still there; the merciless blast of ultraviolet light from the Sun should have long-ago disintegrated the nylon in the flags. Perhaps when we go back we'll see tri-colored dust at the poles' bases.

But even if the flags are gone, the accomplishment remains. We went to the Moon six times, and brought those men home safely again.
