NAME Apollo 17 ALSEP Work Tape Lunar Ejecta And Meteorites Experiment Raw Cleaned ASCII Data Collection (1976-061 to 1976-200)
TYPE Data
DESCRIPTION This collection contains fixed-width ASCII files of daily raw cleaned science measurements acquired by the Lunar Ejecta And Meteorites (LEAM) Experiment at the Apollo 17 landing site for the time span of 01 March through 18 July 1976, which were the last 140 days of LEAM operation. These data were extracted from Apollo Lunar Surface Experiments Package (ALSEP) normal-bit-rate Work Tape files that contain time-edited and rearranged raw binary data transmitted from the Moon. The extracted binary data were corrected for obvious bit errors then transformed to ASCII format for this archive. This collection also includes ASCII files of LEAM-related command verification and raw analog housekeeping data extracted from the Work Tape binary files.

PRIMARY RESULT DESCRIPTION Measurements of cosmic dust impacts (lunar ejecta, interstellar grains, and cometary debris) taken on the surface of the Moon by the Apollo 17 Lunar Ejecta And Meteorites Experiment during the time span of 01 March through 18 July 1976, which were the last 140 days of LEAM operation. The scientific objectives were to measure the speed, direction, total energy (kinetic and potential), and momentum of primary cosmic dust particles and lunar ejecta.
