NASA的好奇号火星探测车通过Mastcam(桅杆相机,探测车的“眼睛”)拍摄到了一系列带有红色和绿色光晕的云层漂浮在火星天空中的图像。这些图像拍摄于1月17日(火星任务的第4,426个火星日或Sol),完整记录了这类夜光云的最新观测情况。
十二年前,NASA使用一项大胆的新技术,利用机器人喷气背包降低火星车的高度,使六轮科学实验室降落在火星上。NASA的好奇号火星车任务在这颗红色星球上度过了12岁的生日,这位六轮科学家在火星山麓缓慢前行,不断有重大发现。仅仅成功着陆火星就是一项壮举,但好奇号任务在2012年8月5日更进一步,以一种大胆的新技术——空中起重机机动降落。
火星车已经到达了一个区域,该区域可能显示出液态水在火星这部分地区流动的时间比之前认为的要长得多。

The unusual mound was visited by the robotic Curiosity rover exploring Mars late last year. Siccar Point not only has a distinctive shape, it has dark rocks above lighter rocks. The apparent much younger age of the dark rocks indicates a time-break in the usual geological ordering of rock layers — by a process yet unknown. The Martian hill is named for Siccar Point on Earth, a place in Scotland itself distinctive as a junction between two different rock layers. Curiosity…
