Electrostatic Dust Mitigation and Manipulation Techniques for Planetary Dust explains how to control and remove dust in space due to the presence of a vacuum, abrasiveness of dust particles and electrostatic charge on particles. The book introduces innovative technologies that use electrostatic and di-electrophoretic forces to remove and transport small particles away from surfaces. In addition, it discusses how to resolve thermal control problems and reduce lung inhalation and eye irritation problems. The book includes two abrasive wear test devices that were designed to study the rate of volume wear for di?erent materials when subjected to lunar dust simulant of di?erent size ranges.
This will be an ideal resource for space system engineers, space exploration researchers, and advanced students and professionals in space engineering.
