Computer-Aided Civil and Infrastructure Engineering, EarlyView.Abstract Grain morphology is a fundamental characteristic of lunar soil that influences its mechanical properties, sintering behavior, and in situ resource utilization. However, traditional two‐dimensional imaging methods are time‐consuming and lack full three‐dimensional (3D) structural information. This study presents an automated deep learning‐based

Study on the feasibility of preparing a continuous fibre using lunar soil simulant
Scientia Sinica Technologica, 2020 The construction of a lunar base is considered to be a giant step for the deep-space exploration by human beings. The in situ utilization of lunar resource is essential for the realization of this ambitious plan.

Laser melting manufacturing of large elements of lunar regolith simulant for paving on the Moon
Scientific Reports, 2023 The next steps for the expansion of the human presence in the solar system will be taken on the Moon. However, due to the low lunar gravity, the suspended dust generated when lunar rovers move across the lunar soil is a significant risk for lunar ...

An Empirical Model to Estimate Abundance of Nanophase Metallic Iron (npFe0) in Lunar Soils
Remote Sensing, 2020 Lunar soils gradually become mature when they are exposed to a space environment, and nanophase metallic iron (npFe0) generates within them. npFe0 significantly changes the optical properties of lunar soils and affects the interpretation of the remotely ...
