High-Fidelity Lunar Regolith Simulant: Laying A Solid Foundation for Lunar Exploration

Lunar regolith is an important strategic space resource. However, the lunar regolith collected from the Moon is extremely scarce and precious, so most of the related engineering and research on Earth must rely on man-made simulants. Unfortunately, the current lunar regolith simulants differ significantly from the real lunar regolith in terms of elemental composition, crystal structure, and the proportion of amorphous components, etc. The primary reason for this discrepancy is the difference between the experimental conditions used to prepare the simulated lunar regolith and the actual conditions on the Moon. Therefore, research based on these simulated lunar regolith samples is likely to produce serious deviations and misjudgments, which could lead to major losses and catastrophic consequences in space missions. To address this issue, this project will use a stepwise hydrolysis method to synthesize raw materials and various treatment technology to simulate the lunar environment, producing high-fidelity lunar soil. This will fill the gap in such products and lay a solid foundation for lunar exploration activities.
