为什么月球上有这么多灰尘？在地球上，岩石被风和水风化，形成土壤和沙子。在月球上，不断的微陨石轰击的历史已经在岩石表面炸开，形成了一层粉状的月球土壤或风化层。对于阿波罗号的宇航员和他们的设备来说，无处不在的细小沙尘绝对是个问题。50年前，1972年12月，在月球表面，阿波罗17号的宇航员哈里森·施密特和尤金·塞尔南需要修理月球车的一个挡火板，以防止尘土沾到他们自己和他们的装备。这张照片展示了他们的尘土覆盖的漫游者的车轮和挡泥板，以及巧妙地应用备用地图，夹子和灰色的“管道胶带”。

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 lunar soil or regolith. For the Apollo astronauts and their equipment, the pervasive, fine, gritty dust was definitely a problem. Fifty years ago, 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".
