这曾经是古代火星上的一个海滩。这张水平压缩的360度全景图是由探索这颗红色星球的好奇号漫游车于2017年拍摄的。奥根奎特海滩以陆地上的奥根奎特海滩命名，有证据表明，很久以前，这个地区在水下，而在其他时候，它在一个古老湖泊的边缘。在中央背景的光峰是夏普山的顶部，好奇号探索过的盖尔陨石坑的中心特征。前景中的部分深色沙子被挖出来进行分析。浅色的基岩是由沉淀物组成的，这些沉淀物很可能沉积在现已干涸的湖床底部。这张特色全景图（这里是互动版）是由100多张照片合成的，似乎是由左下角的火星车签名的。

This was once a beach -- on ancient Mars. The featured 360-degree panorama, horizontally compressed, was taken in 2017 by the robotic Curiosity rover that explored the red planet. Named Ogunquit Beach after its terrestrial counterpart, evidence shows that at times long ago the area was underwater, while at other times it was at the edge of an ancient lake. The light peak in the central background is the top of Mount Sharp, the central feature in Gale Crater where Curiosity explored. Portions of the dark sands in the foreground were scooped up for analysis. The light colored bedrock is composed of sediment that likely settled at the bottom of the now-dried lakebed. The featured panorama (interactive version here) was created from over 100 images and seemingly signed by the rover on the lower left.
