Researchers at the University of Colorado at Bolder have discovered a promising method for cleaning lunar dust off of space suits and other surfaces likely to be contaminated on the Moon. The solution could be zapping the nasty grit with an electron beam.
Lunar dust sticks to just about everything because it acquires an electrostatic charge from the solar wind. By directing an electron beam at the surface contaminated with dust particles, an excess negative charge will build up resulting in the grains repelling each other and leaping off the surface where the beam is applied. Taking an electron beam shower may be how lunar settlers clean off before coming inside after walks on the Moon.
