Bombardment history of the Moon constrained by crustal porosity

The source data is the modeling result regarding the origin of crustal porosity for the Moon. In this study, we find that the crustal porosity of the early Moon was likely to be high, generated by large basins in its early bombardment history. This high porosity can be reduced over time by smaller impacts or overburden pressure. Our porosity evolution model is based on the observed GRAIL (Gravity and Recovery Interior Laboratory) datasets and global lunar crater catalog and can explain the porosity distribution in the present-day lunar crust.
