Lunar impact basins revealed by GRAIL and hydrocode impact modeling
From Curtin University, Australia
The lunar mission GRAIL provided us with a high-resolution gravity map of the entire Moon and allowed for a detailed study of lunar craters and basins. Numerical impact modelling validated against the GRAIL data resulted in a high definition of the lunar basin formation process, including excavation of the crust and mantle, formation of inner and outer basin rings, as well as investigation of the crustal porosity and derivation of new impact scaling relationships. It was shown that regional thermal differences on the Moon within the first billion years following lunar formation played a large role in basin formation process. Also, recent comparison of the numerical results with the Kaguya spectral data made insights about the lunar composition.
