A total of 17 orbits is requested for exploration of theSaturn magnetosphere to define the morphology of OH discoveredin August 1992 in GO3644, and observed again in December 1994(GO5391). These HST FOS observations definitively establishedthe fact that neutral gas dominates the magnetosphere, with amixing ratio to ions over the range 15 in 1992 to greater than100 in 1994, whereas previous theory was dependent on mixingratios < 0.05. The change in brightness between the FOS 1992and 1994 observations and incompatibility with the Voyagerplasma model, taken together, strongly suggest that theneutral content of the magnetosphere is significantlytemporally variable. Theoretical calculations of source ratescannot account for the large values inferred from theobservations. These considerations indicate that thephenomenon, which obviously has a profound effect on themagnetosphere, is not understood at a first order level. Wetherefore propose further HST FOS observations in an attemptto set limits on source properties, and obtain additionalmorphological information that only HST can provide. Theobservation plan is to obtain 1) a direct limit on sourcestrength at the satellite Tethys, 2) a measure of abundance at3 R_S, the nearest point to Saturn now considered thepractical limit for observation, and 3) a measure oflatitudinal extent of the neutral gas that has not beenpreviously obtained. The measurements are expected to greatlyfacilitate experiment strategy for the Cassini Mission.
