Viscosity measurements of selected lunar regolith simulants
American MineralogistAbstract In the context of evaluating lunar construction options, this study focuses on characterizing the viscosities and glass transition properties of lunar regolith simulants to support the development of additive manufacturing processes using molten regolith. Employing the modular TUBS lunar regolith simulant system, we measured the

Recovery rate prediction in lunar regolith simulant drilling
Acta Astronautica, 2017Abstract Drilling and coring, as an effective way to acquire lunar regolith along the depth, is widely used in the field of planetary explorations. Because there is no relative sliding between the lunar regolith and the flexible tube, using the flexible tube coring method can acquire high recovery rate and keep the stratification of regolith samples.

Strength Properties of JSC-1A Lunar Regolith Simulant
Journal of Geotechnical and Geoenvironmental Engineering, 2009The paper presents a description of physical properties and a characterization of shear strength behavior of JSC-1A lunar regolith simulant. Specific gravity of solids, particle size analysis, and minimum and maximum index densities were measured according to ASTM standards.

Drilling Results in Ice-Bound Simulated Lunar Regolith
AIP Conference Proceedings, 2007Reaching the cold traps at the lunar poles and directly sensing the subsurface regolith is a primary goal of lunar exploration, especially as a means of prospecting for future In Situ Resource Utilization (ISRU) efforts. The Construction and Resource Utilization Explorer project (CRUX) addressed technology development associated with a modular ...

Particle Shape In Simulants of the Lunar Regolith
Journal of Sedimentary Research, 2012Abstract Shape is an important property of lunar regolith particles. It substantially affects the regolith’s strength, the angle of repose, the packing density, and the ability of regolith particles to attach to and abrade spacecraft materials or clog air filters. For these reasons, simulants are needed to reproduce regolith particle shapes for testing

Electrical stress and strain in lunar regolith simulants
Planetary and Space Science, 2011Abstract Experiments to entrain dust with electrostatic and fluid-dynamic forces result in particulate clouds of aggregates rather than individual dust grains. This is explained within the framework of Griffith-flaw theory regarding the comminution/breakage of weak solids.
