LUNAR REGOLITH SIMULATION AT MICROWAVES
Journal of Radio Electronics, 2023 А remote measurement of the lunar regolith temperature from a lander is expected in the near future. A special bench for experimental testing of the experiment details has been created. The test bench simulates the measurement of the temperature of the lunar regolith at depths down to 1 m.

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.

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).
