The dark side of the moon is the face that faces away from the earth. The moon rotates on an axis in geosynchronous fashion so that we always see the same features/face. Very few people have seen the dark (far) side of the moon with their own eyes. https://en.wikipedia.org/wiki/Far_side_of_the_Moon
