The Moon’s farside South Pole–Aitken (SPA) basin is the largest and oldest visible impact basin in the inner Solar System. Determining the timing of this catastrophic event is key to understanding the onset of the lunar basin-forming epoch, with implic

Here, we present hydro- and mantle convection numerical simulations of the giant impact event that formed the South Pole–Aitken basin—the largest impact basin on the Moon—and the subsequent impact-induced convection with the assistance of gravitational instability. We find that the impact induces...
provide critical clues about the Moon’s origin and evolution. A sample could also help scientists put a firm date on the impact. SPA is thought to be the Moon’s oldest basin, so a firm date would be a key milestone in the timeline of lunar history as well as events affecting early ...
