Over 13 years and 293 orbits, Cassini produced more than 450,000 images. They exposed a Saturn system rich with mystery—and two potentially habitable moons. The insights began with the Huygens probe, dropped on Titan—Saturn9s largest moon—revealing a world of hydrocarbons, and continued on to Enceladus, a tiny frozen moon, where Cassini spotted jets of water spewing from its south pole, signs of a liquid water ocean under a thin icy crust. The spacecraft and its international team watched storms on Saturn9s placid surface and, as its long seasons turned to summer, spotted a mysterious hexagonal jet stream on its north pole.

发现的遗产

在 13 年和 293 个轨道上，卡西尼号产生了超过 450,000 张图像。他们揭露了一个充满神秘色彩的土星系统，以及两颗可能适合居住的卫星。这些洞见始于惠更斯号探测器，降落在土星 9 号最大的卫星土卫六上，揭示了一个碳氢化合物的世界，然后继续到土卫二，一个冰冻的小卫星，卡西尼号在那里发现了从其南极喷出的水流，这是液态水的迹象薄冰壳下的海洋。航天器及其国际团队在土星平静的表面观察了风暴，随着漫长的季节转向夏季，在其北极发现了神秘的六边形急流。
