The icy volcanism of Charon may be caused by its internal ocean freezing, expanding, and cracking the outer shell of the moon if it was thinner than expected.
to be an inert ball of ice. Since then a science team led by Southwest Research Institute researchers has been investigating the New Horizons data, attempting to discover the cause of these frigid geological features. Team member and SwRI researcher Alyssa Rhoden is an expert in the geophysics of icy satellites, especially ones that host their own oceans.
Rhoden modeled how fractures formed in the ice shell of Charon as the ocean beneath it froze to better understand the evolution of this moon's surface and interior. The oceans factored in the models were composed of water, ammonia, and a combination of the two. Even though ammonia can act as antifreeze and high concentrations could help preserve the duration of liquid oceans, Rhoden found the different compositions of the ocean didn't have substantial effects on their results.
The team searched for conditions that would allow fractures to fully penetrate the icy shell of Charon to link surface and subsurface water to allow for ocean-sourced cryovolcanism. This revealed that current theories surrounding the evolution of Pluto's moon could be incorrect. This is because these theories suggest that Charon ice shells were far too thick to be fully cracked by the stresses associated with ocean freezing.
