A cold cathode ionization gauge was left on the lunar surface by the Apollo 14 astronauts to measure the neutral gas density on the moon. The gauge has detected the presence of a very low concentration of atmospheric particles at night, about 200,000 per cu cm. Gas clouds of locally greater concentrations have been observed at times, and, while the possibility that these are artifacts associated with the Apollo hardware cannot be conclusively ruled out, the clouds appear to be of natural origin. Contaminant gases due to the Apollo operation dominate during the lunar day, but these may dissipate within a few months.
