DESCRIPTION |
This collection contains fixed-width ASCII files of daily raw cleaned science and
engineering measurements acquired by the Lunar Surface Magnetometer (LSM) at the Apollo 16
landing site for the time span of 02 April through 30 June 1975. 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 one
ASCII file of LSM-related command verification data extracted from the ARCSAV binary
files.

PRIMARY RESULT DESCRIPTION |
Raw measurements of the three orthogonal vector components of magnetic fields at
the lunar surface acquired by the three fluxgate sensors of the Apollo 16 Lunar Surface
Magnetometer Experiment during the time span of 02 April through 30 June 1975. The scientific
objectives were to measure remanent and induced lunar magnetic fields to investigate the
following properties of the lunar interior and the lunar environment: (1) global electrical
conductivity and temperature of the Moon, (2) lunar magnetic permeability and iron abundance,
and (3) lunar remanent magnetic fields and their interaction with the solar wind
plasma.
