Apollo 15 ALSEP ARCSAV Heat Flow Experiment Raw Cleaned ASCII Data Collection (1975-092 to 1975-181)

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 15 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 15 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.
