The Moon’s environment presents unique challenges, and lunar dust is one of the principal limiting factors in returning to the lunar surface for missions of any extended duration. The lunar surface consists of highly cohesive, abrasive regolith with wide-ranging particle sizes (from dust to sand) that may be electrostatically charged. In addition to threatening astronaut health, lunar dust issues have also resulted in incorrect instrument readings, vision and optical system obscuration, performance reduction, altered thermal properties, and equipment failure. To land large payloads on the Moon, the HLS uses rocket engines for descent, landing, and ascent. High-velocity dust ejected by descent engine exhaust can cause damage to a lander, as well as nearby surface assets, which will have negative consequences as NASA strives for sustainable lunar exploration. When the plumes interact with the lunar regolith, surface erosion and cratering begin, and the interaction produces high-speed ejecta. The lofted regolith and high velocity ejecta can reduce visibility of sensors and optics, sandblast nearby landed assets, and erode the surface around the vehicle. These interactions between the plume(s), surface, erosion, and ejecta are termed Plume-Surface Interaction (PSI); and understanding and mitigating PSI effects are critical for safe landings and sustainable exploration on the Moon.
