Simplified Particle Models and Properties Analysis Designed for DEM Lunar Soil Simulants

Aerospace
The discrete element method (DEM) is one of the most popular methods for simulating lunar soil simulants due to the lack of real lunar soil. To reduce the computational consumption and difficulty because of complex particle models, simplified particle ...

Development and characterization of a regional lunar soil simulant for emirates lunar missions

International Journal of Mining Science and Technology
Lunar soil simulants (LSS) have been pivotal in the success of past and current lunar missions. They have enhanced the design of lander and rover wheels through interaction studies on the lunar testbed under simulated environmental conditions.

Artificial Space Weathering to Mimic Solar Wind Enhances the Toxicity of Lunar Dust Simulants in Human Lung Cells

GeoHealth
During NASA's Apollo missions, inhalation of dust particles from lunar regolith was identified as a potential occupational hazard for astronauts. These fine particles adhered tightly to spacesuits and were unavoidably brought into the living areas of the

Regolith behavior under asteroid-level gravity conditions: low-velocity impact experiments

, 2018
The dusty regolith covering the surfaces of asteroids and planetary satellites differs in size, shape, and composition from terrestrial soil particles and is subject to very different environmental conditions.

The effects of lunar dust accumulation on the performance of photovoltaic arrays [PDF]

Lunar base activity, particularly rocket launch and landing, will suspend and transport lunar dust. From preliminary models, the resulting dust accumulation can be significant, even as far as 2 km from the source.
