Europa's Icy Crust Rotation Linked to Ocean Currents, Study Shows.

New computer modeling suggests that the ocean currents on Jupiter's moon, Europa, may be affecting the rotation of its icy shell. The research hints at how the power of the ocean flow and its drag against the ice layer could even account for some of the geology seen on Europa’s surface. NASA's upcoming Europa Clipper mission aims to determine if Europa, with its deep internal ocean, has conditions that could be suitable for life.
