Summary

This paper presents the geotechnical, geochemical, and mineralogical characterization of highland lunar regolith simulants, including Lunar250 and EAC-1. The study focuses on properties such as particle size distribution, particle shape, abrasivity, density, water content, major and trace element geochemistry, and modal mineralogy. The work supports the monitoring of geotechnical property variations in the Luna Analog Facility testbeds. This paper presents updated geotechnical, geochemical, and mineralogical data for lunar regolith simulants used in the Luna Analog Facility (LAF) testbeds. The simulants include highland regolith from Lumina Sustainable Materials Ltd. and mare regolith EAC-1. The study characterizes particle size distribution, shape, and other properties using methods like X-ray computed tomography, sieving, and sedimentation. This paper characterizes four lunar regolith simulants: Lunar90, Lunar250, Lunar2000, and EAC-1. The study includes particle shape analysis, abrasivity testing, particle density, and bulk density measurements. The simulants are sourced from Lumina Sustainable Materials Ltd. and the European Astronaut Centre (EAC). 2.5 mm). The volume of sample
