PDS: The Planetary Atmospheres Node
Description of the data.
The Peregrine Ion-Trap Mass Spectrometer (PITMS) was an ion trap mass spectrometer with a zenith-looking aperture. Neutral gas species that entered the aperture were trapped by the PITMS radiofrequency field and detected according to their mass-to-charge ratio. PITMS was operated in one of multiple Scan Functions that defined the parameters of the trapping and detection electronics. The PITMS goal was to monitor the tenuous near-surface lunar exosphere in response to natural (e.g., diurnal temperature cycle) and artificial (e.g., landing event, lander activities) stimuli.
The data extends from 2024-01-12T10:33:23 to 2024-01-15T13:25:19 and the products in this bundle contain the calibrated mass spectrum for each PITMS measurement. The spectrum is composed of m/z and ions (all scan functions) and background-subtracted partial pressure.
