“…Table 3 indicates, for a generic simulant, the main properties to be investigated, the tests that can be performed to fulfill the purpose, and an indication of the simulant utilisation context. The list is not exhaustive for peculiar applications [36,37], but it can provide a complete overview for applications that range from physical-chemical manipulation to handling and interaction with the materials. The user, according to the application of interest, selects the tests to perform.…”

Since the landing on the lunar surface, the lunar regolith has begun to interact in different ways with landed elements, such as the wheels of a rover, astronaut suits, drills, and plants for extracting oxygen or manufacturing objects. Therefore, a strong effort has been required on Earth to fully characterise these kinds of interactions and regolith utilisation methods. This operation can only be performed by using regolith simulants, soils that are reproduced with the Earth’s rocks and minerals to match the real features. This article presents the main guidelines and tests for obtaining the properties of a generic simulant in terms of composition, physical and mechanical properties, solid–fluid interaction, and thermal properties. These parameters are needed for the designing and testing of payloads under development for planned lunar surface missions. The same tests can be performed on lunar, martian, or asteroid simulants/soils, both in laboratory and in situ. A case study is presented on the lunar simulant NU-LHT-2M, representative of the lunar highlands. The tests are performed in the context of an in situ resource utilisation (ISRU) process that aims to extract oxygen from the lunar regolith using a low-temperature carbothermal reduction process, highlighting the main regolith-related criticalities for an in situ demonstrator plant.

“…Zhang et al [13] conducted GDS resonant column tests to investigate the dynamic properties of lunar soil simulant (CAS-1), and discussed the effects of the confining pressure and porosity on the dynamic shear modulus and damping ratio. Prabu et al [14] investigated the dynamic properties of the new LSS-ISAC-1 lunar highland simulant, and the variation patterns of shear modulus and damping ratio were obtained by cyclic triaxial experiments. Although there is limited studies on the dynamic behavior of lunar soil simulant under cyclic triaxial experiments, it has been aroused great interest in the dynamic behavior of lunar soil simulant.…”

Study of the mechanical properties of lunar soil simulant is the key to conducting lunar soil sampling and lunar base construction. In this paper, conventional and cyclic triaxial tests are performed by using discrete element method (DEM) to study the mechanical properties of QH-E lunar soil simulant. The results indicate that the confining pressure has an important impact on the shear strength and dynamic modulus of QH-E lunar soil simulant. In the conventional triaxial test, with the increasing of the confining pressure, both the peak deviatoric stress and residual stress increase, and the relevant results have been supported by experiments. In cyclic triaxial test, the area of cyclic hysteresis loop decreases with the increasing of the number of cycles, the axial strain and dynamic modulus first increase and then tend to be stable with the increasing of the number of cycles. Moreover, the axial strain increases with increasing confining pressure, while dynamic modulus decreases at a specific cyclic stress ratio (CSR) condition.
