Summary

The paper discusses the development and similarity assessment of a new lunar highland simulant, LSS-ISAC-1, for use in lunar habitat materials and structures. It outlines the source material, mineralogical and chemical composition, and the methods used for similarity assessment. The study also evaluates the geomechanical properties of LSS-ISAC-1, including particle size analysis, morphology, specific gravity, bulk and relative density, shear strength, and compressibility. The findings suggest that LSS-ISAC-1 is a suitable simulant for lunar regolith and could be used in future lunar missions. 016 STANDARDTESTMETHODSFORMINIMUMINDEXDENSITYUNITWEIGHTSOILSCALCULATIONRELATIVEDENSITY 2016 STANDARDTESTMETHODSFORMAXIMUMINDEXDENSITYUNITWEIGHTSOILSUSINGAVIBRATORYTABLE 2017 STANDARDTESTMETHODSFORLIQUIDLIMITPLASTICLIMITPLASTICITYINDEXSOILS 2017 STANDARDPRACTICEFORCLASSIFICATIONSOILSFORENGINEERINGPURPOSESUNIFIEDSOILCLASSIFICATIONSYSTEM 2017 STANDARDTESTMETHODFORPARTICLESIZEDISTRIBUTIONGRADATIONFINEGRAINEDSOILSUSINGSEDIMENTATIONHYDROMETERANALYSIS BARNES 2014 244 252 J BASU 1996 777 782 A BEAN 1970 29 38 A APOLLO12PRELIMINARYSCIENCEREPORTNASASP235 CREWOBSERVATIONS BENAROYA 2002 33 45 H BENAROYA 2
