Structural mapping of Enceladus and implications for formation of tectonized regions

Crow-Willard, Emma N.; Pappalardo, Robert T.

Global structural mapping of high-resolution Cassini images of Enceladus reveals a richly varied surface. Most notable are three main regions of deformation each containing multiple structural units. In addition to the well known "South Polar Terrain" (SPT), there are two other large regions of deformation that we term "Leading Hemisphere Terrain"…

Dynamics of Saturn's polar regions

Hueso, R.; Sánchez-Lavega, A.; Antuñano, A. +1 more

We analyze data retrieved by the imaging science system onboard the Cassini spacecraft to study the horizontal velocity and vorticity fields of Saturn's polar regions (latitudes 60-90°N in June-December 2013 and 60-90°S in October 2006 and July-December 2008), including the northern region where the hexagonal wave is prominent. With the aid of an …
