Flying Moondust

Here is an interesting article about the possible dangers of flying moondust when we go back to the Moon, particularly to stay at moonbases. The film and video of lunar landings and liftoffs showed the dust flying off at high speeds. During landing, the Lunar Modules (LMs) descent engine scoured the surface as the lander approached, kicking dust out at speeds of probably around a kilometer per second. Without an atmosphere on the Moon, the dust will fly off on ballistic trajectories rather than billowing like it does on Earth during rocket launches that we see commonly on TV. The article above shows the affects of concrete blasted out of the flame trenches of the shuttle launch pads that drill holes in fences and damage other equipment. The smaller rockets used in landing on the Moon will not have enough force to blow big rocks out, but instead, it is the smaller dust that will be dangerous to equipment on the Moon at a moonbase.
