These odd ridges are still a mystery. Were they formed by glaciers? Oceans? Image: NASA/JPL-Caltech/Univ. of Arizona



A vast area of Martian rice paddies? Lizard skin? Nope, just an area of intersecting sand dunes. Image: NASA/JPL-Caltech/Univ. of Arizona


This double impact crater was caused by a meteorite that split into two before hitting Mars. Notice how the eroding force of the wind has shaped each crater the same, smoothing one edge and creating dunes in the same place. Image: NASA/JPL-Caltech/Univ. of Arizona

NASA 展延任務  MRO

（项目科学家：Rich Zurek博士，JPL）。MRO提供了有关火星表面过程的大量数据。在其第六次延长任务中，MRO将研究火星表面、冰层、活动地质、大气和气候的演变。此外，MRO将继续为其他火星任务提供重要的数据中继服务。MRO的CRISM仪器将被完全关闭，因为它的低温冷却器的丢失已经结束了它的两个光谱仪中的一个的使用。
