Summary

The paper introduces CLDS-i, a lunar regolith simulant developed for space exploration and research. It details the mineralogy, bulk chemistry, particle size, morphology, and the presence of nanometer-sized iron oxide grains (Np-Fe0) in the simulant. The simulant is designed to closely mimic the properties of actual lunar regolith, making it useful for testing equipment and experiments in simulated lunar environments. This paper introduces CLDS-i, a lunar dust simulant with high similarity to real lunar dust in chemistry, mineralogy, particle size, morphology, and nanophase Fe0. It is used for engineering tests and toxicological studies. The paper introduces CLDS-i as a lunar dust simulant used for toxicological research and dust protection technology development. It highlights the simulant's properties related to composition, grain size, morphology, and magnetic behavior, which are critical for understanding health impacts on astronauts. The simulant is noted for its similarity to real lunar dust in terms of particle size, shape, and potential health effects.
