      Description

      3 Panel Mosaic image

      The lunar south pole is located near the bottom of this mosaic taken a few days before the full moon phase. The mountains visible along the lunar limb at the bottom can rise about 6 kilometers above the surrounding terrain.

      The large prominent crater just above the center is Clavius. It is one of the largest craters on the Moon, with a diameter of 230 km (140 miles), as well as one of the oldest and was probably formed during the Nectarian period, about 4 billion years ago. In October 2020, NASA confirmed the existence of molecular water near Clavius, with its origin still debated. Another rather interesting crater, located entirely within the southern (bottom) rim of Clavius, is Rutherfurd crater. Rutherfurd's edge is higher than that of Clavius, while its floor is irregularly shaped and jagged. Porter crater, located above Rutherfurd, is the other large crater superimposed on the rim of Clavius.

      Just below and to the left of Clavius is crater Scheiner and to its right, below Clavious, lays crater Blancanus. While the rim of Scheiner is heavily worn, in particular in the northern part, the rim of Blancanus is considerably less eroded and still fairly well defined.

      Another notable crater in the region near the Moon's south pole is Moretus, in the lower right of this image. The floor of Moretus has been partially covered by lava and is relatively flat, with a central mountain formation that rises about 2 kilometers (1.3 miles). Due to the location near the lunar limb, Moretus appears oblong due to perspective.
