It is of extreme interest to NASA and the scientific community to confirm the presence of plumes of water ice venting from the polar regions of Europa. Roth et al 2014 presented evidence, based on line emission imaging of the dissociation products of water, that such plumes exist. We were awarded three orbits in Cycle 21 to pursue a completely independent approach to imaging the Europa exosphere, including a search for Enceladus-like plumes. In the FUV, Jupiter provides a uniformly illuminating backlight screen against which absorption by Europa's exosphere can be imaged as it transits Jupiter. The spatial resolution of HST is high in the FUV and molecular cross-sections are high. We request six additional STIS orbits, and two WFC3 orbits to provide sensitive limits on the absorbing column density and on entrained dusty particulates. Roth et al seek line emission at apoapsis and periapsis. We will span a range between these limits, closer to apoapsis where plumes are predicted. With the additional orbits we double our S/N and gain a factor of two in detectable column density, seek the scientific gold standard of reproducibility with multiple datasets, and provide a completely independent, contemporaneous (crucial when probing a transient phenomenon) validation of the line-emission approach. Our observations so far provide fascinating hints, but require confirmation through repeats and improved S/N. With a concerted effort, we have the opportunity to conclusively and unequivocally establish the presence of ice fountains on Europa. If they arise from the deep ocean, we have gained access to probably the most astrobiologically interesting location in the Solar System. We will obtain a single ACS/SBC prism observation inside and outside eclipse. We will obtain one orbit that sweeps through all filters outside eclipse and the remaining four orbits will be inside eclipse. Three use broad filters and one uses the narrow band optical filters to seek auroral emission.
