Scientific paper

We propose to obtain the most detailed view yet of Io's dynamic SO_2 / S_2 atmosphere, and the first spectroscopic observations of a Prometheus-type plume, to test models of plume and atmospheric chemistry and dynamics. We will use STIS on eight HST orbits, spread over four Io days, to obtain a spatial profile of S_2 and SO_2 gas abundance across a region of Io that includes a wide variety of terrain types and latitudes, centered on the Prometheus volcano. In addition, we will obtain two orbits of G140L wide-slit STIS data, which provides an image of Io in reflected Lyman-Alpha which we will compare to our SO_2 distribution data to test the hypothesis that Io's dark equatorial region in these images results from absorption of Lyman-Alpha by SO_2.
