Where on the Moon is the South Pole-Aitken Basin primarily located?
Answer
The southern hemisphere on the side perpetually facing away from Earth
The South Pole-Aitken Basin (SPA) occupies a substantial portion of the Moon's southern hemisphere. Crucially, this entire region is situated on the far side of the Moon, which is the hemisphere that remains perpetually facing away from Earth due to synchronous rotation. This location is significant because the impact event that created the SPA was powerful enough to punch through a significant thickness of the lunar crust, offering scientists insights into the Moon's deeper interior structure located on this less-studied hemisphere.
