The emerging technologies of Far-Ultraviolet polarimetry and spatial heterodyne spectroscopy (SHS) offer an important opportunity to study energetic processes in planetary atmospheres and the interaction of the Sun with the local interstellar medium. In collaboration with CNES, we have begun a program to develop instrumentation to observe H Ly-alpha emission from the Jovian atmosphere, comets, and the interplanetary and local interstellar mediums. We are currently working toward the launch of two polarimetric spectrometers, one a wide field SHS instrument to polarimetrically probe the heliopause, the velocity structure of comet comae, and the density of H in the interplanetary medium. Secondly, we are developing a telescope-imaging spectrometer to observe polarized H Ly-alpha emission from the Jovian equatorial anomaly and the aurora. We will discuss the scientific rationale for these programs, the instrumental techniques being used, and our future plans for the experiments.
