Nasa code AS8-14-2453

After inserting into lunar orbit, the Apollo 8 astronauts looked down on rugged terrain never before seen by man. This scene is typical of farside terrain illuminated by a sun that is nearly directly overhead. A surface consisting of craters superimposed on older craters extends about 570 kilometers (350 statute miles) to the horizon. Width of view at the horizon is 150 kilometers. Signs of wear.
