DOI: 10.1029/2024gl110034
Abstract: The formation and evolution of the South Pole‐Aitken (SPA) basin is critical to relating large impact basin formation and modification to lunar geophysical evolution. Most prior models of the SPA impact were conducted in 2D,… read more here.

Abstract: Lunar mare basalts illuminate the nature of the Moon’s mantle, the lunar compositional asymmetry and the early lunar magma ocean (LMO)1, 2–3. However, the characteristics of the mantle beneath the vast South Pole–Aitken (SPA) basin… read more here.

DOI: 10.1126/sciadv.abm8475
Abstract: The formation of the largest and most ancient lunar impact basin, South Pole–Aitken (SPA), was a defining event in the Moon’s evolution. Using numerical simulations, we show that widespread mantle heating from the SPA impact… read more here.

DOI: 10.1130/g47280.1
Abstract: The South Pole–Aitken (SPA) basin, located between the South Pole and Aitken crater on the far side of the Moon, is the largest confirmed lunar impact structure. The pre-Nectarian SPA basin is a 2400 ×… read more here.
