S72-37255 (November 1972) --- The Lunar Atmospheric Composition Experiment (Lunar Mass Spectrometer), Experiment S-205, one of the experiments of the Apollo Lunar Surface Experiments Package which will be carried on the Apollo 17 lunar landing mission. The LACE will measure components in the ambient lunar atmosphere in the range of one to 110 atomic mass units (AMU). The experiment will be set up 15 meters northwest of the ALSEP central station. After placement, it will be heated to drive off contaminated gases. The instrument will be turned on by ground command after lunar module ascent during the first lunar night and will be active thereafter.
