In the 2024 study, Lainey and his colleagues seem to have nailed the case. They went deeper than they did in the first half of the year by looking at other things, such as how Mima’s rotation changed over time. The team combined Cassini observations with simulations of Mimas’s interior and its orbit to conclude that there must be an ocean 20–30 kilometres below Mimas’s surface.
