Scientific paper

The INMS instrument is a quadrupole mass spectrometer with two sample inlets for making in-situ measurements of neutral gas and low energy ions along the Cassini spacecraft track. Since orbit insertion in July 2004, measurements have been made above Saturn's ring plane, in the upper atmosphere and ionosphere of Titan, and near the gas plume in the south polar region of Enceladus. Water is inferred from ion measurements above the ring plane and is also the dominant species in the south polar Enceladus plume along with N2/CO, CH4 and CO2. While N2 and CH4 are predominant in Titan's upper atmosphere, smaller concentrations of hydrocarbons and nitrile compounds have been detected in both the neutral gas and the more complex ion composition. The ionosphere composition has been used, in turn, to infer the presence of many low concentration N-containing neutral species. Near the exobase the change in the N2 density scale height with altitude above 1600 km has been used to imply a "hot” neutral gas corona with the increased gas temperature due to additional plasma heating. A summary of these results are presented in this poster paper.
