你想过在外星世界冲浪吗？我们现在可以扩大对从地球到太阳系其他地方的完美波的搜索，甚至更远。科学家们开发了一种新的模型来模拟其他行星上的波。土卫六是迄今为止已确认的274颗土星卫星之一，也是太阳系中（除地球外）唯一已知表面有液态湖泊和海洋的物体。这段特色视频展示了在相同条件下地球（右）和土卫六（左）上的波浪模拟（刻度标记以米为单位）。微风会在土卫六上产生比地球上更高、移动速度更慢的波浪，因为土卫六上的湖泊充满了轻质液态碳氢化合物，而且土卫六的重力较低，大气压力较高。几年后，美国宇航局预计将发射蜻蜓号任务，该任务将飞行6年，并发射一架旋翼飞行器探索土卫六，研究其微生物的可居住性。

Have you ever thought about surfing on an alien world? We can now expand the search for the perfect wave from Earth to the rest of the Solar System, and beyond. Scientists have developed a new model for simulating waves on other planets. Titan is one of the 274 confirmed moons of Saturn to date, and the only object in the solar system (besides Earth) known to have liquid lakes and seas on its surface. The featured video shows a simulation of waves on Earth (right) and on Titan (left), under the same conditions (the scale marker is in meters). A light breeze would create taller, slower-moving waves on Titan than on Earth, because the lakes there are filled with light liquid hydrocarbons, and because of Titan's low gravity and higher atmospheric pressure. In a couple of years, NASA expects to launch the Dragonfly mission, which will travel for 6 years and send a rotorcraft to explore Titan and study its microbial habitability.
