High-resolution images of the martian surface at scales of a few meters show ubiquitous erosional and depositional eolian landforms. Dunes, sandsheets, and drifts are prevalent and exhibit a range of morphology, composition (inferred from albedo), and age (as seen in occurrences of different dune orientations at the same location). Steep walls of topographic depressions such as canyons, valleys, and impact craters show the martian crust to be stratified at scales of a few tens of meters. The south polar layered terrain and superposed permanent ice cap display diverse surface textures that may reflect the complex interplay of volatile and non-volatile components. Low resolution regional views of the planet provide synoptic observations of polar cap retreat, condensate clouds, and the lifecycle of local and regional dust storms.
火星表面数米尺度的高分辨率图像显示出无处不在的侵蚀和沉积风成地貌。沙丘、沙席和沙堆很普遍，呈现出一系列形态、成分（由反照率推断）和年龄（如在同一地点不同沙丘方向的出现情况所见）。峡谷、山谷和撞击坑等地形凹陷的陡峭壁面表明火星地壳在几十米的尺度上是分层的。南极层状地形和叠加的永久冰盖呈现出多样的表面纹理，可能反映了挥发性和非挥发性成分的复杂相互作用。对该行星的低分辨率区域观测提供了极冠退缩、凝结云以及局部和区域沙尘暴生命周期的全景观测。
