Waves hit different on other planets

MIT and WHOI scientists have developed 'PlanetWaves,' the first wave model to capture full wave dynamics under varying planetary conditions. The model accounts for gravity, liquid composition (density, viscosity, surface tension), and atmospheric pressure to predict wave behavior on other worlds. Validated against 20 years of Lake Superior buoy data, it reveals striking differences: on Saturn's moon Titan, gentle breezes generate 10-foot waves in slow-motion due to light liquid hydrocarbons and low gravity, while hurricane-force winds would barely ripple the lava oceans of exoplanet 55-Cancri e. The model was also applied to ancient Mars, and exoplanets LHS1140b and Kepler 1649b. Beyond scientific curiosity, the findings could inform spacecraft design for future Titan missions and help explain planetary landscape mysteries like the absence of river deltas on Titan.
