Ralph Lorenz of APL gave a talk yesterday that discussed the puzzling stillness seen in Titan’s northern lakes. Given the moon’s super-rotating atmosphere and low gravity, one might expect Cassini to see some choppiness on the hydrocarbon seas. Lorenz lays out two possibilities to explain this: Either the lakes are viscous and stiff, or the changing seasons will bring winds to the north — which means that Cassini, in its new Solstice Mission, ought to catch some breakers in the act.
