urn:nasa:pds:a17hfe_thermal_conductivity 1.0 1.23.0.0 Product_Bundle 2025 10.17189/0ar3-k165 This data set comprises a reduced, subsampled set of the data returned from the Apollo 17 Heat Flow Experiment from 12 December 1972 through 31 December 1974. The experiment consisted of two probes placed by the Apollo 17 astronauts in holes drilled in the lunar surface near the Apollo 17 Lunar Surface Experiments Package site to measure the thermal conductivity. The data consist of a set of ten ASCII tables with time, temperature differences, and average temperatures readings measured by the thermocouples in the heat flow probes and probe cables. The data have been restored and reformatted from binary data held on magnetic tapes at the NASA National Space Science Data Center (NSSDC) under NSSDC ID of PSPG-00022 (old NSSDC ID 72-096C-01A).
