In 2005 Saturn’s moon Enceladus was discovered to be an active world with water ice particle geysers at its south pole. The driver of this activity on a moon so small remains a mystery. One possible explanation has been suggested by Dr. Francis Nimmo, a planetary scientist from the University of California Santa Cruz. Nimmo visited the University of Arizona Lunar and Planetary Laboratory to present his model on Thursday, September 18, 2007 for the department’s weekly Planetary Sciences Colloquium. The talk was based on his recent publication [reprint PDF] “Shear heating as the origin of the plumes and heat flux on Enceladus” in Nature.

In addition to deep fractures and grooved lanes, Enceladus has several other types of tectonic terrain. Figure 9 shows sets of narrow fractures (still several hundred metres wide) that were first discovered by the Cassini spacecraft. Many of these fractures are found in bands cutting across cratered terrain. These fractures appear to propagate down only a few hundred metres into the crust. Many appear to have been influenced during their formation by the weakened regolith produced by impact craters, often changing the strike of the propagating fracture.[30][31] Another example of tectonic features on Enceladus are the linear grooves first found by Voyager 2 and seen at a much higher resolution by Cassini. Examples of linear grooves can be found in the lower left of the figure at top and Figure 10 (lower left), running from north to south from top center before turning to the southwest.

Enceladus has a moon with surface geography of widely varying age, some areas as young as 100 million years old. Enceladus is geologically active, as discovered by the recent Cassini spacecraft which explored Saturn and moons in the early to mid-2000s. A plume of water was observed, heat emanating from the planet, and a near-complete lack of craters in the south polar region, showing geological activity. As for the source of cryovolcanism, it is thought that deep warm rocks created through tidal heating feed small underground water pockets, which in turn release their pressure to the surface through the path of least resistance.

Enceladus has become the first tiny moon to join the Earth, Io, and Triton as worlds known to have current and active volcanic activity. The exact process that drives this activity on Enceladus is still unclear. Scientists believe the tug of war between Titan and Saturn with Enceladus in the middle induce internal friction below the moon’s surface. They are unsure if this results in a partially melted mantle near Enceladus’ south pole, and whether or not this material erupts as liquid water that quickly freezes, or as already frozen water ice particles. What they can be certain of is that their preconceived notions about small moons were wrong.

Warm Fractures on Enceladus: This image shows the warmest places in the south polar region of Saturn's moon Enceladus. The unexpected temperatures were discovered by Cassini's composite infrared spectrometer during a close flyby on July 14, 2005. The image shows how these temperatures correspond to the prominent, bluish fractures dubbed "tiger stripes," first imaged by Cassini's imaging science subsystem cameras. Working together the two teams were able to pinpoint the exact location of the warmest regions on Enceladus. (Credit: NASA/JPL/GSFC/Space Science Institute)
