   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".
