接近土星会是什么样子？你不需要想象——卡西尼号飞船在2004年就做到了这一点，沿途记录了数千张照片，进入轨道后又记录了数十万张照片。卡西尼号的一些早期图像经过了数字调整、裁剪，并汇编成这段鼓舞人心的视频，这段视频是一个更大的IMAX电影项目的一部分，名为《土星环》。在最后的镜头中，土星越来越大，而多云的土卫六在下面俯冲。在土星旋转的背景下，卡西尼号在土卫一上空飞行，巨大的赫歇尔陨石坑清晰可见。当卡西尼号穿过土星的薄环平面时，土星雄伟的光环接管了整个节目。光环的黑影出现在土星上。最后，神秘的冰喷泉卫星土卫二出现在远处，然后在视频剪辑结束时接近。经过十多年的探索和发现，卡西尼号宇宙飞船在2017年燃料不足，被指示进入土星的大气层，在那里它肯定融化了。APOD的主要NASA网站正在迁移：从APOD .

What would it look like to approach the grand planet Saturn? One doesn't have to just imagine -- the Cassini spacecraft did just this in 2004, recording thousands of images along the way, and hundreds of thousands more since entering orbit. Some of Cassini's early images have been digitally tweaked, cropped, and compiled into the featured inspiring video which is part of a larger IMAX movie project named In Saturn's Rings. In the concluding sequence, Saturn looms increasingly large on approach as cloudy Titan swoops below. With Saturn whirling around in the background, Cassini is next depicted flying over Mimas, with large Herschel Crater clearly visible. Saturn's majestic rings then take over the show as Cassini crosses Saturn's thin ring plane. Dark shadows of the ring appear on Saturn itself. Finally, the enigmatic ice-geyser moon Enceladus appears in the distance and then is approached just as the video clip ends. After more than a decade of exploration and discovery, the Cassini spacecraft ran low on fuel in 2017 was directed to enter Saturn's atmosphere, where it surely melted.
