This zoomed-in view of Saturn’s moon Epimetheus, one of the highest resolution ever taken, shows a surface covered in craters, vivid reminders of the hazards of space.
Epimetheus (70 miles across) is too small for its gravity to hold onto an atmosphere. It is also too small to be geologically active. That means there is no way to erase the scars from meteor impacts, except for the generation of new impact craters on top of old ones.
This image, taken by our Cassini spacecraft was aquired at a distence of approximately 9,300 miles.
