Thermal properties of processed lunar regolith simulant [PDF]
International Journal of Applied Ceramic Technology, 2019 Abstract In this paper, the thermal characterization of lunar regolith simulant, sintered using a conventional oven under ambient and vacuum conditions is presented. Additionally, thermal characterization of samples is performed for the parts manufactured using solar, laser, and microwave processing.

Triboelectric charging of lunar regolith simulant [PDF]
Journal of Geophysical Research: Space Physics, 2009 We present an experimental investigation of the triboelectric charging behavior of lunar simulant (JSC‐1). Our experimental approach ensures that the JSC‐1 particles only make contact to other JSC‐1 particles during the charging process (and no other surfaces).

Functional Comparison of Lunar Regoliths and Their Simulants [PDF]
Journal of Aerospace Engineering, 2013 AbstractLunar regolith simulants are essential to the development of technology for human exploration of the Moon. Any equipment that will interact with the surface environment must be tested with simulant to mitigate various risks, such as unexpected mechanical abrasion, chemical interactions, or thermal failures. To reduce the greatest amount of risk,

Thermal Properties of Lunar Regolith Simulants [PDF]
Earth and Space 2010, 2010 Various high temperature chemical processes have been developed to extract oxygen and metals from lunar regolith. These processes are tested using terrestrial analogues of the regolith. But all practical terrestrial analogs contain H2O and/or OH-, the presence of which has substantial impact on important system behaviors.

Simulation of the Lunar Regolith and Lunar-Penetrating Radar Data Processing
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2018 Lunar-penetrating radar (LPR) was conducted by the “Yutu” rover of China's Chang-E 3 lunar mission to study the shallow subsurface of the Moon. Both regolith modeling and numerical simulation can provide a reliable reference for data processing of the Moon.

Shear Properties of Lunar Regolith Simulants
Procedia Engineering, 2014 AbstractThe accuracy of lunar regolith simulants for lunar drilling and sampling is mainly based on their particle shape and grain size distribution. To determine the grain-size distribution and shear strength parameters, grain-size distribution tests and conventional tri-axial compression experiments were conducted on the lunar regolith simulants.
