Explanation: The Moon’s south pole is toward the top left of this detailed telescopic moonscape. Captured on August 23, it looks across the rugged southern lunar highlands. The view’s foreshortened perspective heightens the impression of a dense field of craters and makes the craters themselves appear more oval shaped close to the lunar limb. Prominent near center is 114 kilometer diameter crater Moretus. Moretus is young for a large lunar crater and features terraced inner walls and a 2.1 kilometer high, central peak, similar in appearance to the more northerly young crater Tycho. Mountains visible along the lunar limb at the top can rise about 6 kilometers or so above the surrounding terrain. Close to the lunar south pole, permanently shadowed crater floors with expected reservoirs of water-ice have made the rugged south polar region of the Moon a popular target for exploration.

说明: 在这幅摄于8月23日、远眺月球南方高原的细致月面望远镜影像里，月球的南极位于左上角。因为视角造成的缩短效应，视觉上这片原野密布着大量的撞击坑，而且越靠近月球临边的撞击坑，其形状愈扁长。影像中心附近最吸睛的结构，是直径114公里的莫雷特斯撞击坑。在月表的大撞击坑之中，莫雷特斯坑相对年轻，具有阶梯状的内墙和2.1公里高的中心峰，外观酷似北方的年轻第谷坑。位于影像顶缘月亮邻边的山峦，高耸出周围的原野达6公里。靠近月球南极的撞击坑里，永夜的坑底预期会是水冰的储存库，故而让月球南极区成为热门的探索目标。
