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.

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.
