Labtayt Sulci on Saturn's Enceladus

Do some surface features on Enceladus roll like a conveyor belt? A leading
interpretation of recent images taken of Saturn's most explosive moon
indicate that they do. This form of asymmetric tectonic activity, very
unusual on Earth, likely holds clues to the internal structure of Enceladus,
which may contain subsurface seas where life might be able to develop.
Pictured above is a composite of 28 images taken by the robotic Cassini
spacecraft in October just after swooping by the ice-spewing orb.
Inspection of these images show clear tectonic displacements where
large portions of the surface all appear to move all in one direction. Near
the top of the image appears one of the most prominent tectonic divides:
Labtayt Sulci, a canyon about one kilometer deep.
