“…Nevertheless, since there is no need to carry large quantities of additives from Earth, the melting/sintering of lunar soil has gradually become the major research interests in recent years for the in situ construction of lunar bases on the lunar surface, with relevant research carried out by many research organizations such as the Loughborough University in the United Kingdom and the Harbin Institute of Technology in China. 158,159…”

“…In-situ resource utilisation (ISRU) of lunar regolith to extract oxygen, water, or construction materials, in particular, would provide many of the key components for habitats, spacecraft fuel and human life support (Corrias et al, 2012;Crawford, 2015;Schlüter and Cowley, 2020), reducing the tonnes of material that would otherwise have been needed to be launched from Earth. Recent advancements in ISRU technology include terrestrial demonstrators of the carbothermal reduction process for extraction of water (Prinetto et al, 2023) and oxygen (White et al, 2023), and additive manufacture of glassy lunar regolith simulant products using laser powder bed fusion (Wang et al, 2023). To carry out these processes, regolith must first be collected from the lunar surface.…”

Introduction: Physical regolith simulants are valuable tools for developing In-Situ Resource Utilisation hardware. However, using virtual models of regolith instead can reduce costs, limit exposure to hazardous materials, and offer a practical method of testing the effects of reduced gravity.Methods: We verify a virtual model of regolith as macroparticles against physical tests. Using space partitioning techniques to identify neighbouring particles, we present a scalable model of regolith, in which the computation time increases roughly proportionally with the number of particles. We evaluated the performance of this virtual simulant vs. a physical simulant (Exolith LMS-1) by comparing the flow rate through funnels of various diameters, and the resultant angle of repose of material on both large (500 g) and small (16 g) scale tests.Results: For large scale tests, the flow rates were within the predicted range for macroparticles with radii 3–7 mm, with the greatest accuracy achieved for radii 4–5 mm. However, the macroparticles blocked the simulated funnels more easily than in the physical trials, due to their high cohesion. The angle of repose was not accurately represented by this model for either of the tests.Discussion: The high efficiency of this model makes it best suited for applications which require large scale approximations of regolith with real-time execution, such as virtual training for robot operators or providing visual and haptic feedback in model-mediated teleoperation systems. The results of this model in reduced gravity could be further verified against data from upcoming lunar missions in future work.
