AB: On October 26, 2004 the Cassini spacecraft had its first near encounter with Titan at 1250 km altitude. We will present the initial Cassini Plasma Spectrometer (CAPS) measurements of ion and electron fluxes as a function of their direction of arrival over a hemispheric field of view and their energy/charge between 1 eV and 50 keV (ions) and 1 eV and 28 keV (electrons). The CAPS ion mass spectrometer also simultaneously makes time-of-flight measurements of ion mass/charge spectra between 1 and ~ 100 amu. A second ion spectrometer will measure ion velocity distributions with resolution of a few percent. We anticipate that CAPS results will include a sounding of the electron density and ion composition; the ion and electron temperatures 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.
