Enceladus: Global Patterns of Fracture (Southern Polar Projection)

Fractures on the surface of Enceladus record a long and complex history of tectonic activity. Many of the geologically youngest fractures define remarkably systematic patterns relative to Enceladus' axis of rotation, as well as to its tidal orientation (that is, the longitudes that point toward and away from Saturn). These fracture patterns offer clues to global changes of shape that the satellite has undergone over time, possibly in response to tidal forces exerted by Saturn or as a result of changes in the internal structure of the icy moon. Some of the most prominent global patterns of fracture are delineated in color in the Southern Hemisphere map shown here.
This map is a polar stereographic projection that was mosaicked from the best-available Cassini and Voyager clear-filter images.
The map is centered on the South Pole and coverage extends to the Equator. Gridlines show latitude and longitude in 30° increments.
