飞越太阳系最大的卫星会是什么感觉？今年6月，朱诺号宇宙飞船飞过木星巨大的卫星木卫三，并拍摄了经过数字构建的详细飞越图像。随着这段特色视频的开始，朱诺号在这颗2000公里宽的卫星的两种色调的表面上俯冲而过，展示了一个充满沟槽和陨石坑的冰冷的外星景观。这些沟槽可能是由移动的地表板块造成的，而陨石坑则是由剧烈撞击造成的。朱诺号继续在轨道上运行，然后第34次近距离掠过木星的云层。这段数字构造的视频显示，北部有许多旋涡云，中部有彩色的行星环绕区和带状地带，其中包括珍珠串上的几朵白色椭圆形云，最后是南部更多的旋涡云。明年9月，朱诺号计划近距离掠过木星的另一颗大卫星：木卫二。

What would it be like to fly over the largest moon in the Solar System? In June, 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 clouds from the String of Pearls, and finally more swirling clouds in the south. Next September, Juno is scheduled to make a close pass over another of Jupiter's large moons: Europa.
