The Flux of Large Impacts on the Moon Enhanced near the Beginning of the Copernican Period
The size–frequency distribution (SFD) of lunar impactors was believed to be time independent for the last 3.5 billion years (Gyr). Here, I use linear and nonlinear topographic diffusion models to determine the degradation states (the integral of ...

New Morphometric Data of Lunar Sinuous Rilles
On the surface of the Moon a large number of linear features are recognizable. Long and narrow depressions are defined as lunar rilles. Their morphology has different characteristics, related to their origin.

Global surface slopes and roughness of the Moon from the Lunar Orbiter Laser Altimeter [PDF]
The acquisition of new global elevation data from the Lunar Orbiter Laser Altimeter, carried on the Lunar Reconnaissance Orbiter, permits quantification of the surface roughness properties of the Moon at unprecedented scales and resolution.

Lateral Variations in Lunar Crustal Thickness Inferred From Apollo Seismic and GRAIL Gravity Data
Abstract The internal structure of the Moon is key to understanding its formation, evolution, and bulk composition. In particular, determining the structure of the crust–mantle interface (Moho), including its lateral variations, is of significant importance, but current knowledge is still insufficient to fully constrain it.

Remote Compositional Analyses of Space-weathered Lunar Maria
Visible-to-shortwave infrared (VSWIR) reflectance spectroscopy has revolutionized our understanding of planetary surface compositions. However, space-weathering processes on airless bodies complicate quantitative compositional analyses.

Morphometric Analysis of the Jingpo Lake Volcanic Field: A Terrestrial Analog for Lunar Lava Flow
The lack of high-precision imaging data for lunar volcanic regions currently hinders the detailed characterization of lava tube systems and their associated fine-scale geomorphology.
