   Explanation: [5]Why is the Moon so dusty? On Earth, rocks are weathered
   by wind and water, creating soil and sand. On the Moon, the history of
   constant micrometeorite bombardment has blasted away at the rocky
   surface creating a layer of powdery [6]lunar soil or regolith. For the
   Apollo astronauts and their equipment, the pervasive, fine, [7]gritty
   dust was definitely a problem. On the lunar surface in [8]December
   1972, Apollo 17 astronauts Harrison Schmitt and Eugene Cernan needed to
   [9]repair one of their rover's fenders in an effort to keep the
   [10]rooster tails of dust away from themselves and their gear. This
   picture reveals the wheel and fender of their dust covered rover along
   with the ingenious application of spare maps, clamps, and a grey strip
   of "duct tape".
