AS08-14-2453 (21-27 Dec. 1968) --- 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 (94 statute miles).
