Apollo 12 ALSEP ARCSAV Solar Wind Spectrometer Raw Cleaned ASCII Data Collection (1975-093 to 1975-182) (PDS)


Availability: Archived at NSSDC, accessible from elsewhere


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. Data available online at:
