NAME Apollo 16 ALSEP ARCSAV Lunar Surface Magnetometer Raw Cleaned ASCII Data Collection (1975-092 to 1975-181)
TYPE Data
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.
