Thermal conductivity of lunar regolith simulant using a thermal microscope
Source abstract
Abstract
Abstract In this study, thermal effusivity distributions of two polished JSC-1A particles, a lunar regolith-simulating material, were measured using a thermal microscope. The results confirmed that the average thermal effusivity of the JSC-1A single particle was approximately half that of the FJS-1 single particle, a different type of lunar regolith-simulating material measured by a similar method. Also, the thermal effusivities of the existing mineral phases of pyroxene and anorthite in the particles were obtained and were comparable to those reported in the literature. A possible reason for the lower thermal conductivity of JSC-1A than that of FJS-1 could be the differences in the ratio of the mineral phases, and phase boundaries between the mineral phases.
