摘要：

The dusty lunar environment can hinder NASA's exploration missions because of its ability to cling to most surfaces. The lunar dust is expected to be electrostatically charged due to solar UV irradiation and its exposure to the solar wind and to cosmic rays. As a result, NASA has an active dust mitigation program that is currently studying possible dust mitigation technologies. The Electrostatics and Surface Physics Laboratory at the Kennedy Space Center, in collaboration with several universities, has been working to develop an ac- tive dust mitigation technology for the last few years. In this paper, we report on our efforts to develop the Dust Shield, a dust removal technology that uses electrostatic and dielectro- phoretic forces to remove dust already deposited on surfaces and to prevent the accumulation of dust particles approaching those surfaces. We also include results of computer simulations of charged particles interacting with these systems. I. INTRODUCTION The entire lunar surface is covered with a layer of dust with sizes in the micrometer and submicrometer range. This layer of dust is expected to be electrostatically charged for three main reasons. First, the moon has practically no atmosphere (it has a tenuous at- mosphere with an atmospheric pressure in the 10-13 kPa range) and no magnetic field so that the high energy electrons and protons in the solar wind reach the surface completely unimpeded. Second, due to the relatively high surface and volume resistance of the lunar regolith and the complete lack of liquid water in the regolith, the charge decay of the lunar dust should approach infinity. Third, due to the lack of an atmosphere, the full
