AB: On 26 October 2004 the Cassini spacecraft makes its first close pass to Titan, passing within approximately 1200 km of the surface. The measurements planned for the Ion Neutral Mass Spectrometer experiment will constitute the first in situ observations of Titan's upper atmosphere. Densities of molecular constituents including N2 and CH4 will be measured as a function of altitude. Analysis of these data will determine the temperature and abundances of the major atmospheric constituents. The abundance of some minor atmospheric constituents may also be determined.
