Thermal conductivity variation of lunar regolith with temperatures estimated using the empirical model. The curves for 1930 and 1950 kg m\(^{-3}\) represent the upper and lower bounds of densities simulated for the location of ChaSTE penetration from the penetration motor current and ground penetration experiments. The temperatures measured are 305 K and 303 K, for the first and second heating experiments, respectively.
