Analysis of Surface Age Dating Techniques and Uncertainties through Comparison of Independently Determined Crater Size–Frequency Distributions at Two Lunar Landing Sites

The Planetary Science Journal
This study compares differences in crater-count-based measurement techniques and determines lava flow ages for geologic context at two NASA Commercial Lunar Payloads Services (CLPS) landing sites.

Shock Metamorphism of Lunar Minerals

Space: Science & Technology
Impact events have played a crucial role in the formation and evolution of the Moon, as evidenced by the numerous of impact craters on its surface, indicating a long history spanning over 4 billion years characterized by numerous such occurrences. As the

Stardust microcrater residue compositional groups [PDF]

, 2007
Compositional groups are defined in residue from Stardust craters (1-9 Dc) by qualitative EDS. These compositional groups are being further studied by a FIB-SEM technique to determine representative residue ...

Catalog of Lunar Craters I [PDF]

This catalog gives the selenographic coordinates of all craters observable on a selected portion of the moon's surface. The diameter of the crater together with comments on shape are also given. Approximately 25 per cent of the craters have been measured

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 ...

Orientale Basin as a Guide for Identifying Lunar Basin Datable Impact Melt and Assessing Impact Melt Differentiation

The Planetary Science Journal
Two fundamental questions face lunar scientists: (1) What is the absolute age of each lunar impact basin and thus the early impact flux curve? (2) To what degree did basin impact melt seas undergo differentiation? We compiled a 1:200,000-scale geological

Selected aspects of lunar mare geology from Apollo orbital photography [PDF]

Crater size-frequency distributions were studied (100-500 m) and are shown to provide significant integrated information concerning mare surface ages, subsurface stratigraphy, and surficial geology.

Cosmic dust in the atmosphere and in the interplanetary space at 1 AU today and in the early solar system [PDF]

A description of techniques used in recent experiments to detect and analyze cosmic dust and micrometeorites is given and the results both from the study of lunar crater statistics and from in situ measurements are reviewed. The results from lunar crater
