High porosity chained aggregates from the topsoil of the lunar regolith dust\ud [PDF]

, 2009
The unusual behaviour of fine lunar regolith like stickiness and low heat conductivity is dominated by the structural arrangement of its finest fraction.

Rheological Lunar Regolith Simulants

IAF Space Exploration Symposium
Regolith simulants are essential for space research and technology development. Yet, their physical properties often differ from those of true planetary soil, particularly when compared to regolith properties in-situ, that experience notably reduced gravity.

Thermophysical Properties of Lunar Regolith Revealed by Thermal-infrared Observations of the Lunar Reconnaissance Orbiter (LRO) Diviner Radiometer

The Astrophysical Journal
The thermophysical properties of lunar regolith are crucial for lunar sciences and engineering. Here, we evaluate the thermophysical properties of lunar regolith between 75°N and 75°S from Diviner data by treating the radius of lunar regolith grains as a

Investigation into failure mechanisms of lunar regolith simulant under thin-walled drilling tool with critical parameters

International Journal of Mining Science and Technology
Acquiring pristine deep lunar regolith cores with appropriate drilling tools is crucial for deciphering the lunar geological history. Conventional thick-walled drill bits are inherently limited in obtaining deep lunar regolith samples, whereas thin ...

Analysis of lunar regolith thermal energy storage [PDF]

, 1991
The concept of using lunar regolith as a thermal energy storage medium was evaluated. The concept was examined by mathematically modeling the absorption and transfer of heat by the lunar regolith. Regolith thermal and physical properties were established
