The Cassini Plasma Spectrometer (CAPS) measures ion energy and mass from 1 eV to 50 keV and electron spectra from 1 eV to 28
keV. It thus fills in important gaps in earlier Voyager measurements of plasma energy and composition. This paper gives an
overview of data taken during the first two Cassini orbits, including the closest approach to Saturn and the rings during the
tour (1.3 $_{S}$), and a close flyby of Titan (1250 km altitude), two passes through Saturn's inner magnetosphere (one at a
moderate, 10-15$^{o}$ latitude height above the equatorial plane, and one crossing the equatorial plane at approximately 8
R$_{S}$), and period of roughly 50 days of solar wind monitoring in conjunction with Cassini remote sensing of Saturn's
aurora. Initial analysis shows the existence of H$^{+}$, H$_{2}$$^{+}$ and/or He$++}$, N$^{+}$, water group, and
O$_{2}$$^{+}$ ions within Saturn's magnetosphere, the exact composition depending on location. Several distinctive regions of
plasma have been identified including a cold ``ionosphere'' located over the rings, a region of quiescent, corotating plasma
between approximately 2 R$_{S}$ and 6 R$_{S}$, a region of highly disturbed plasma between 6 $_{S}$ and 14 $_{S}$,
containing numerous injection and/or local acceleration events, and a region of hot, very low density plasma outside
approximately 14 $_{S}$. We also anticipate being able to give an overview of observations of plasma in the proximity of
Titan and its ionosphere.
