The South Pole–Aitken basin (SPA Basin, / ˈ eɪ t k ɪ n /) is an immense impact crater on the far side of the Moon. At roughly 2,500 km (1,600 mi) in diameter and between 6.2 and 8.2 km (3.9–5.1 mi) deep, it is one of the largest known impact craters in the Solar System. It is the largest, oldest, and deepest basin recognized on the Moon. [1]
The south pole region features many craters and basins such as the South Pole–Aitken basin, which appears to be one of the most fundamental features of the Moon, [7] and mountains, such as Epsilon Peak at 9.050 km, taller than any mountain found on Earth. The south pole temperature averages approximately 260 K (−13 °C; 8 °F). [7]

The Procellarum KREEP Terrane, or PKT, is a large province on the near side of the Moon that has high abundances of KREEP.KREEP is an acronym built from the letters K (the atomic symbol for potassium), REE (rare-earth elements) and P (for phosphorus), [3] and is a geochemical component of some lunar impact breccia and basaltic rocks.
In between these events, the Moon reached its highest point in the zenith and then its selenographic directions are lined up with those on Earth. In mid southern latitudes (South America, South Pacific, Australia, South Africa) the Moon rises in the east with its southeastern limb up (Mare Nectaris), it reaches its highest point in the north ...
Sunlight reflects off objects on the moon the same way it does here on Earth. So all of these images and videos include light reflecting from Earth, the lunar module, and from the dust on the surface.
