Mapping Cryovolcanic Activity from Enceladus' South-Polar Region
Abstract
Using Cassini images taken of Enceladus' south polar plumes at various times and orbital locations, our goal is to determine which fractures are active and inactive at each time. Maps of activity at various orbital phases will help test the hypothesis that Tiger Stripe activity is affected by Enceladus' orbital position around Saturn via tidal forcing. To produce our maps, we use simulated curtains of ejected material that are superimposed over Cassini images. The images are organized into sets representing various epochs and orbital longitudes, and view the plumes from multiple angles. Source fractures are determined either by triangulation, or by matching the shadows cast onto the erupted material by the terminator of the satellite.
