Why is Moondust So Clingy? - Universe Today
One of the main challenges of returning humans to the Moon will be how to deal with all that gritty, clingy moondust. Scientists believe that ultraviolet radiation charges individual grains of dust, giving them a static charge. NASA is studying individual grains of moondust returned by Apollo astronauts to how much charge they can build up, and the results have been surprising. Ultraviolet radiation can give a grain of moondust 10 times more charge than the theories had calculated.
