Lunar surface materials have extremely low thermal conductivity. For measuring the lunar heat flow value in future lunar landing missions, it is important to understanding how the low conductivity is established. This study aimed at understanding the heat transfer mechanism in powder media such as the lunar surface materials. The thermal conductivity of glass beads as powder sample was measured with varying powder pressure and particle size under high vacuum conditions. It was found that the powder pressure significantly affects the thermal conductivity of glass beads, and comparison of our experimental data with a theoretical model indicated that the dependence on the powder pressure was seen on 1/3 power curves.
