The Cassini spacecraft will make its first, close flyby of Titan on October 26, 2004. We will present the initial Cassini Plasma Spectrometer (CAPS) results from this 1250 km altitude encounter. CAPS measures ion and electron flux as a function of energy, direction over a hemispheric field of view and between 1 eV and 50 keV (ions) or 1 eV and 28 keV (electrons). The ion spectrometer also makes time-of-flight measurements of ion mass. The main, expected CAPS results include a sounding of electron density and ion composition, and the ion and electron temperature down to an altitude of 1250 km; the pitch angle distributions of magnetospheric electrons entering Titan's atmosphere; and the properties of the magnetospheric plasma upstream and in the flanks of the Titan interaction region.
