The paper presents the thermal characterization of glasses prepared from simulated lunar soil (JSC-1A). The study uses an experimental setup to measure thermal properties and discusses the results in the context of lunar base construction and material selection for extraterrestrial environments. The paper presents the thermal characterization of a glass prepared from JSC-1A lunar soil simulant. The thermal conductivity (K) and thermal diffusivity (α) were measured using a combination of open photoacoustic cell (OPC) and thermal relaxation techniques. The values obtained were K = (20 ± 3) mW/cmK and α = (14 ± 2) cm²/s, which are somewhat higher than those of comparable silicate glasses. The specific heat capacity (c) was found to be (1.44 ± 0.07) J/cm³K, slightly lower than that of similar glasses. The study highlights the importance of thermal properties in materials used for space applications, as high thermal conductivity and diffusivity can enhance resistance to thermal shock. This is the first report of thermal diffusivity and thermal conductivity for JSC-1A lunar simulant. This paper reports thermal properties of glasses made from JSC-1A lunar soil simulant.
