Charon Flyover from New Horizons

Explanation: What if you could fly over Pluto‘s moon Charon — what might you see? The New Horizons spacecraft did just this in 2015 July as it zipped past Pluto and Charon with cameras blazing. The images recorded allowed for a digital reconstruction of much of Charon‘s surface, further enabling the creation of fictitious flights over Charon created from this data. One such fanciful, minute-long, time-lapse video is shown here with vertical heights and colors of surface features digitally enhanced. Your journey begins over a wide chasm that divides different types of Charon’s landscapes, a chasm that might have formed when Charon froze through. You soon turn north and fly over a colorful depression dubbed Mordor that, one hypothesis holds, is an unusual remnant from an ancient impact. Your voyage continues over an alien landscape rich with never-before-seen craters, mountains, and crevices. The robotic New Horizons spacecraft has too much momentum to ever return to Pluto and Charon and is now headed out of our Solar System.

新视野号飞越冥卫一

说明: 如果能飞越冥王星的冥卫一（Charon），会看到什么？新视野号探测器曾在2015年7月掠过冥王星和冥卫一，当时探测器上的相机火力全开，并拍下了大量的照片。这些照片让我们得以使用数位技术重建大部分的冥卫一表面，更让我们能够根据这些数据，制作出一些虚拟的冥卫一飞越影片。其中之一就是上面这部很酷炫，长1分钟、表面结构的垂直高度和色泽都经过数位强化的时序影片。旅程起始于一道分隔冥卫一不同形态表面的宽广深谷，而这道深谷则可能形成于冥卫一通体冻结之时。很快的，视线北转飞越一个色彩缤纷名为魔多的凹地，有假说指出它是一次远古撞击事件的遗迹。最后，旅程掠过一片到处都是前所未见撞击坑、山峰和裂缝的异星原野。带着极高动量踏上离开 太阳系旅程的新视野号探测器，不可能再回访冥王星与冥卫一。
