The Moon is a unique body in our Solar System that allows us to groundtruth remotesensing
data (eg, crater size–frequency distributions, or CSFDs, crater/rock degradation rates …

In this work we update the regolith mixing model presented by Gault et al.(1974), including
new input values and reworking key parameters. Much as Gault et al. did, we present a way …

Small craters of the lunar maria are observed to be in a state of equilibrium, in which the rate
of production of new craters is, on average, equal to the rate of destruction of old craters …

Impact gardening is a mixture of excavation by impacts and burial under continuous
proximal ejecta. An existing analytical model describes the rate at which impacts excavate …

Lunar regolith is the layer of fragmented and unconsolidated rock material that is repeatedly
stirred and overturned on the lunar surface. It can provide critical information about lunar …

In this work, we divide the classic" lunar megaregolith" layer into three distinct regions:(1) a
Surficial Regolith layer, about 5–20 m in depth, consisting of loose, unconsolidated fines …

Impact cratering is the dominant process for transporting material on the Moon's surface. An
impact transports both proximal material (continuous ejecta) locally and distal ejecta (crater …

Examining the topography of impact craters and their evolution with time is useful for
assessing how fast planetary surfaces evolve. Here, new measurements of depth/diameter …

The lunar landscape evolves both physically and chemically over time due to impact
cratering and energetic processes collectively known as space weathering. Despite returned …

Of the several near-Earth and Main Belt asteroids visited by spacecraft to date, three display
a paucity of small craters and an enhanced number of smoothed and degraded craters: 433 …
