Lunar Surface Geology From Analysis of Impact Craters and Their Ejecta

, 2007
Analysis of impact craters and their ejecta addresses someunanswered questions about the lunar surface. First I estimatethe regolith depth on the south farside of the Moon to be about40 m, which is significantly deeper than the nearside regolith ...

A comparison between terrestrial, Cytherean and lunar impact cratering records [PDF]

Monthly Notices of the Royal Astronomical Society, 2002
A comparison between the terrestrial, Cytherean and lunar cratering records indicates that the large craters (diameters D > Do) on these surfaces all have cumulative numbers that are proportional to D - 2 . 5 9 γ 0 . 0 5 . Atmospheres have a negligible effect on the formation of D > Do craters. It is shown that this limiting diameter is 45 ′ 3

Topographic knowledge-aware network for automatic small-scale impact crater detection from lunar digital elevation models

International Journal of Applied Earth Observations and Geoinformation
Impact craters represent the most prevalent and prominent topographical features on the surfaces of planets. They provide crucial insights into the internal and surface-level geological activities of planets but are difficult to identify from digital ...

The distribution and modes of occurrence of impact melt at lunar craters [PDF]

, 1992
Numerous studies of the returned lunar samples as well as geologic and remote-sensing investigations have emphasized the importance of impact melts on the surface of the Moon. Information concerning the distribution and relative volumes is important for (

Identification of Lunar Craters in the Chang’e-5 Landing Region Based on Kaguya TC Morning Map

Remote Sensing
Impact craters are extensively researched geological features that contribute to various aspects of lunar science, such as evaluating the model age, regolith thickness, etc. The method for identifying impact craters has gradually transitioned from manual

The Effect of Antecedent Topography on Complex Crater Formation

Geophysical Research Letters
Impact craters that form on every planetary body provide a record of planetary surface evolution. On heavily cratered surfaces, new craters that form often overlap antecedent craters, but it is unknown how the presence of antecedent craters alters impact

Intelligent Detection of Lunar Impact Craters Using DEM and Gravity Data Based on ResNet and Vision Transformer

Applied Sciences
The craters on the moon hold important clues about the history of impacts in our solar system. To address the limitation of traditional intelligent methods in detecting buried craters, this study proposes a novel intelligent detection approach based on ...

Chronology, Local Stratigraphy, and Foreign Ejecta Materials at the Chang'e‐6 Landing Site: Constraints on the Provenance of Samples Returned From the Moon's Farside

Geophysical Research Letters
China's Chang'e‐6 (CE‐6) mission has returned the first‐ever lunar farside samples from a mare plain on the southern Apollo basin floor. The crater statistics of the CE‐6 mare unit and the provenance of the samples are crucial in interpreting the CE‐6 ...

The Population of Young Craters on the Moon: New Catalog and Spatial and Temporal Analysis

The Planetary Science Journal
We present a new catalog of the Moon’s rayed and rocky craters from 5 to 130 km in diameter. Using data from the Lunar Reconnaissance Orbiter and the JAXA Kaguya/Selene missions, we identify 571 unique craters with albedo, maturity, and/or thermophysical
