Much of Mars is covered by sand and dust but in some places stacks of sedimentary layers are visible. In this image, exquisite layering is revealed emerging from the sand in southern Holden Crater. Sequences like these offer a window into Mars’ complicated geologic history.

Holden Crater was once a candidate landing area for the Curiosity, Mars Science Laboratory, and is still an intriguing choice today.

火星的大部分地区被沙尘覆盖,但在一些地方可以看到成堆的沉积层。在这张图片中,霍尔顿陨石坑南部的沙子上呈现出精致的分层。像这样的科学为了解火星复杂的地质历史提供了一个窗口。

霍尔顿环形山曾经是“好奇号火星科学实验室的候选着陆区域,今天仍然是一个有趣的选择。
