Why is the Moon dusty?On Earth, rocks are weathered by wind and water, creating soil and sand.On the Moon, the long history o micrometeorite bombardmenthas blasted away at the rocky surface creating a layer of powder lunar soil or regolith.This lunar regolith could be scientific an industrial bonanza.But for the Apollo astronauts an their equipment,the pervasive, fine, gritty dust was definitely a problem Onthe lunar surface in December 1972 Apollo 17 astronautsHarrison Schmitt and Eugene Cernan needed to repair one of theirlunar rover's fender in an effort to keep the"rooster tails" of dust away from themselves and their gear This picture reveals the wheel andfender of their dust covere rover along withthe ingenious application of spare maps,clamps, and a grey strip of "duct tape".
