NAME Apollo 12 ALSEP ARCSAV Solar Wind Spectrometer Raw Cleaned ASCII Data Collection (1975-093 to 1975-182)
TYPE Data
DESCRIPTION This collection contains fixed-width ASCII files of daily raw cleaned science measurements and daily raw calibration and engineering data acquired by the Solar Wind Spectrometer (SWS) at the Apollo 12 landing site for the time span of 03 April through 01 July 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 SWS-related command verification data extracted from the ARCSAV binary files.

PRIMARY RESULT DESCRIPTION Electron and positive ion flux measurements taken on the surface of the Moon by the Apollo 12 Solar Wind Spectrometer during the time span of 03 April through 01 July 1975. The instrument observed the directional intensities of the electron (6-1330 eV) and positive ion (18-9780 eV) components of the solar wind and magnetotail plasma that strike the surface of the Moon. The scientific objectives were to study the existence of the solar wind plasma on the Moon, the properties of the lunar surface and interior, general solar wind properties, and the magnetospheric tail of the Earth.
