The internal structure of the Moon, from surface to core, preserves a record of its evolution
from accretion to present-day. The structure of the Moon is unique in the Solar System by …

This chapter is dedicated to H. Jay Melosh who tragically passed away during this endeavor.
From his earliest publications on the concept of acoustic fluidization, to the publication of his …

Abstract The South Pole–Aitken (SPA) basin is the oldest and largest impact structure on the
Moon, and it gives particular insight on the lunar interior composition,–. However, the …

Multiring basins, large impact craters characterized by multiple concentric topographic rings,
dominate the stratigraphy, tectonics, and crustal structure of the Moon. Using a hydrocode …

The Orientale basin is a multiring impact structure on the western limb of the Moon that
provides a clear view of the primary lunar crust exposed during basin formation. Previously …

Global maps of crustal thickness on the Moon, derived from gravity measurements obtained
by NASA's Gravity Recovery and Interior Laboratory (GRAIL) mission, have shown that the …

The Moon exhibits striking geological asymmetries in elevation, crustal thickness, and
composition between its nearside and farside. Although several scenarios have been …

The commonly adopted ejecta deposit models always assume vertical impacts for
simplification. However, most impacts on planetary surfaces are oblique, which produce …

Impact basins provide windows into the crustal structure and stratigraphy of planetary
bodies; however, interpreting the stratigraphic origin of basin materials requires an …

We model the formation of lunar complex craters and investigate the effect of preimpact
porosity on their gravity signatures. We find that while preimpact target porosities less than …
