Thermal conductivity and diffusivity of Apollo 15 fines at low densityThe thermal conductivity of the Apollo 15 fines, sample 15031,38, was measured under vacuum conditions as a function of temperature. Measurements were made for a sample density of 1300 kg/cu m. The conductivity was found to vary from about .00057 W per m per K at 95 K to about .00136 W per m per K at 406 K. The data are compared with the correlation using a cubic temperature dependence and also with data from samples gathered during prior Apollo missions. The thermal diffusivity is obtained for the sample by calculation using the given density and measured thermal conductivity along with specific heats from the literature.
