From year to year, the moon never seems to change. Craters and other formations appear to be permanent now, but the moon didn't always look like this. Thanks to NASA's Lunar Reconnaissance Orbiter, we now have a better look at some of the moon's history. A new video that sgows us changes on lunar surface has been released by NASA. Some effects seem exagerated, but nonetheless the big picture is there.
The original site of the movie is at Goddard Space Flight Center's webpage.
