Lunar Dust and Dust Mitigation Testing

Lunar dust was one of the most persistent problems for the Apollo astronauts due to its’ abrasiveness and strong adherence to surfaces. With the Artemis program, NASA is planning longer stays on the lunar surface, with more activities that have the potential to put the astronauts and equipment in contact with greater quantities of lunar dust. The success of these missions will depend on our understanding of material interactions with lunar dust and the development of ways to mitigate dust effects. This is particularly true in cases where exposure to dust will lead to failure of components, unacceptable loss of power or thermal control, unacceptable loss of visibility, or health issues. Lunar dust, issues with lunar dust, and ground testing with lunar simulant will be discussed as well as the development of and planned flight testing of optically transparent work function matching coatings to reduce adhesion of dust on the lunar surface.
