      Explanation: Why is the Moon so dusty? On Earth, rocks are weathered by   
      wind and water, creating soil and sand. On the Moon, eons of constant   
      micrometeorite bombardment have blasted away at the rocky surface   
      creating a layer of powdery lunar soil or regolith. For the Apollo   
      astronauts and their equipment, the pervasive, fine, gritty dust was   
      definitely a problem   
      . On the lunar surface in December 1972, Apollo 17 astronauts Harrison   
      Schmitt and Eugene Cernan needed to repair one of their rover's fenders   
      in an effort to keep the 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".
