This high-resolution view of Saturn’s moon Epimetheus shows a surface covered in craters, vivid reminders of the hazards of space. At 70 miles or 113 kilometers across, Epimetheus is too small for its gravity to hold onto an atmosphere. It is also too small to be geologically active. There is therefore no way to erase the scars from meteor impacts, except for the generation of new impact craters on top of old ones.
