英文原文:Explanation: What would it be like to fly over the largest moon in the Solar System ? In 2021, the robotic Juno spacecraft flew past Jupiter 's huge moon Ganymede and took images that have been digitally constructed into a detailed flyby. As the featured video begins, Juno swoops over the two-toned surface of the 2,000-km wide moon, revealing an icy alien landscape filled with grooves and craters. The grooves are likely caused by shifting surface plates, while the craters are caused by violent impacts . Continuing on in its orbit, Juno then performed its 34th close pass over Jupiter's clouds. The digitally-constructed video shows numerous swirling clouds in the north, colorful planet-circling zones and bands across the middle -- featuring several white-oval cloud s from the String of Pearls , and finally more swirling clouds in the south. 说明: 想像一下,飞越太阳系中最大的卫星[8]会是什么样的景象? 2021年,朱诺号探测器[9]飞越木星[10]巨大的卫星木卫三(甘尼米德)[11],拍摄的图像经数字合成技术制作成一段精细的飞掠视频。 当精选视频[12]开始时,朱诺号掠过这颗直径2,000公里的卫星,其表面呈现出双色调,展现出一片充满沟壑和陨石坑的冰冷外星地貌。 这些沟壑[13]很可能是由地表板块移动造成的,而陨石坑则是由猛烈撞击[14]所形成。 随后,朱诺号继续绕着木星轨道运行,完成了第34次近距离飞掠[15]木星云层的任务。 这段数字合成的视频[16]展示了北半球的众多旋转云层[17],中间则是色彩斑斓的环绕木星的区域和带状云层[18]——其中包括「珍珠串」[19]中几朵白色椭圆云[20],最后在南半球则有更多旋转[21]的云层。
