NASA好奇号火星车于2026年8月11日当地时间早晨8:30利用Mastcam合成6张照片，拍摄了火星夏普山上一处沙岩地貌全景图1。这片地貌跨越约16公里，位于夏普山西北部，其独特的颜色和地层倾角表明其成因可能超出普通风蚀作用的解释范围1。
项目科学家阿什温·瓦萨瓦达表示："这一层沙岩看起来不合适。颜色错误，地层倾角奇怪，几乎像是贴上去的。但正是这样才令人兴奋。没有人确切知道是什么创造了这一层，但一个想法是它可能是古代火山喷发沉积的灰烬。"1
好奇号自2014年以来一直在攀登高约5公里的夏普山1。近期该火星车完成了0.6公里的高度提升，超过了火星其他任何漫游车的同期进展1。NASA科研团队计划在2027年到达这片沙岩地貌的底部进行近距离调查1。
NASA's Curiosity rover captured a panoramic image on August 11, 2026—sol 4982 in Mars time—revealing a striking series of wind-eroded sandstone cliffs spanning approximately 10 miles (16 kilometers) across the northwestern region of Mount Sharp.1 The distinctive geological formation displays unusual coloration and layering angles that suggest origins beyond typical erosion processes, sparking scientific intrigue about its potential connection to ancient volcanic activity.1
The panoramic image was composed from six photographs taken by the rover's Mastcam instrument.1 Project scientist Ashwin Vasavada described the discovery as anomalous, stating: "This sandstone layer looks out of place. The color is wrong, the layer angles are strange, almost like it was pasted on. But that's exactly what makes it exciting. No one knows for certain what created this layer, but one idea is that it could be ash deposited from an ancient volcanic eruption."1 The formation's enigmatic nature has prompted researchers to plan a closer investigation, with the team targeting arrival at the base of the sandstone cliffs in 2027.1
Curiosity has been ascending Mount Sharp—which reaches approximately 3 miles (5 kilometers) in height—since 2014.1 Recently, the rover achieved an elevation gain of 0.6 miles (1 kilometer), surpassing any other rover on Mars.1
