AB: The Cassini Ion and Neutral Mass Spectrometer (INMS) onboard the Cassini Orbiter measured the neutral composition and structure of the upper atmosphere of Titan during the first flyby (Ta) of this satellite. The INMS detected N2, CH4, and H2, the noble gas argon, and a host of more complex hydrocarbon and nitrile species. INMS also made neutral measurements during the Tb flyby. During the T5 Titan flyby, which took place in April 2005, the INMS measured both the neutral and the ion composition of the upper atmosphere and ionosphere. These measurements will be summarized in this talk. The implications of these measurements for our current understanding of the photochemistry, dynamics, and energetics of Titan's upper atmosphere and ionosphere will also be discussed.
