Abstract

"Moon Dust" is expected to become one of the most mission critical problems for both astronauts and machineries for the planned extended stay on the Moon. The challenges associated with the mitigation of the charged fine moon dust have been identified in the wide range of areas ranging from nanotoxicology to failed seals. In this preliminary simulation study, negatively charged particles are injected to a container that is filled with positively charged particles. Each negatively charged particle carries the same amount of charge; however, the amount of charge carried by a positively charged particle is scaled with its surface area. This feasibility study addresses issues associated with the effects of particle surface on the rate of coagulation.
