NAME Apollo 17 ALSEP ARCSAV Heat Flow Experiment Raw Cleaned ASCII Data Collection (1975-092 to 1975-181)
TYPE Data
DESCRIPTION This collection contains two fixed-width ASCII files of daily raw cleaned science measurements acquired by the Heat Flow Experiment (HFE) at the Apollo 17 landing site for the time span of 02 April through 30 June 1975. One table provides Mode 1 (Gradient) data while the other table provides Mode 3 (Housekeeping) data. These data were extracted from NASA's original Apollo Lunar Surface Experiments Package (ALSEP) archive tapes, also known as ARCSAV tapes, that recorded 24-hour, time-edited, and rearranged raw binary data transmitted from the Moon. The extracted binary data were corrected for obvious tape read errors then transformed to ASCII format for this archive. This collection also includes ASCII files of HFE-related command verification and raw analog housekeeping data extracted from the ARCSAV binary files.

PRIMARY RESULT DESCRIPTION Temperature differences and thermal conductivity measurements in the near-surface layers of of the moon by the Apollo 17 Heat Flow Experiment during the time span of 02 April through 30 June 1975. The data were acquired by thermocouples in the two heat flow probes and probe cables. The scientific objective was to determine the rate of heat loss from the lunar interior by temperature and thermal property measurements at and below the surface.
