如果你能飞越火星的北极，你会看到什么？2019年欧洲航天局“火星快车”任务拍摄的图像被汇编成特色视频，展示了这样的一次旅行。首先，你看到下面的景观是被细土中生锈的铁染成橙色的，一些土地由于暴露的岩石而显得更暗。很快，北极的冰帽映入眼帘，大部分是白色的，因为它反射着冰冻的水。围绕着极帽的是北极盆地，这是一个覆盖着灰尘和沙子的分层洼地。这段特色视频中的画面是在火星北部春季拍摄的，当时二氧化碳冰正在蒸发，留下了下面的水冰。火星快车号继续研究火星表面，寻找这颗红色星球古代气候和生命潜力的线索。

If you could fly over the North Pole of Mars, what would you see? Images from ESA’s Mars Express mission in 2019 were compiled into the featured video which shows just such a trip. First you see below you a landscape tinted orange by rusted iron in the fine soil, with some land appearing darker due to exposed rock. Soon the northern polar cap comes into view, mostly white because of its reflective frozen water. Surrounding the polar cap is the North Polar Basin, a layered depression covered with dust and sand. The frames in the featured video were captured during northern Martian Spring when the carbon-dioxide ice is evaporating, leaving the underlying water-ice in the cap. Mars Express continues to study the Martian surface and look for clues about the Red Planet's ancient climate and potential for life.
