Abstract

Amendments to a quantitative scheme developed by T.R. McGetchin et al. (1973) for predicting the distribution of ejecta from lunar basins yield substantially thicker estimates of ejecta, deposited at the basin rim-crest and at varying ranges byond, than does the original model. Estimates of the total volume of material ejected from a basin, illustrated by Imbrium, also are much greater. Because many uncertainties affect any geometric model developed primarily from terrestrial analogs of lunar craters, predictions of ejecta thickness and volume on the Moon may range within at least an order of magnitude. These problems are exemplified by the variability ofT, thickness of ejecta at the rim-crest of terrestrial experimental craters. The proportion ofT to crater rim-height depends critically upon scaled depth-of-burst and whether the explosive is nuclear or chemical.

Evidence of shallow basaltic lava layers in Von Kármán crater from Yutu-2 Lunar Penetrating Radar
2024, Icarus
Yutu-2 – the rover from the Chang’E-4 mission – is the longest operational Lunar rover, and the first rover to land on the far side of the Moon. It is the second planetary rover to be equipped with ground-penetrating radar (GPR), one of the few in-situ geophysical techniques used in planetary exploration. Since landing in 2019, Yutu-2 has travelled more than 1 kilometre in the Von Kármán (VK) crater, and has been able to investigate the dielectric properties of the shallow Lunar ejecta using its on-board high frequency GPR channels. In this paper, we use advanced signal processing and frequency attributes to infer a detailed dielectric structure of the first $\approx$ 30 metres of the subsurface, providing valuable information on the ilmenite content of the landing site. Both the dielectric properties and the ilmenite content suggest a shallow sequence of Imbrian basaltic layers overlaying a low-ilmenite ejecta blanket.
3D-simulation of lunar megaregolith evolution: Quantitative constraints on spatial variation and size of fragment
2022, Earth and Planetary Science Letters
Citation Excerpt :
The petrophysical properties of megaregolith, such as porosity and related strength, significantly differ from pristine rocks resulting in variations in the relationship between impact crater size and impact energy (Marchi et al., 2011). The thickness of the megaregolith layer was investigated based on ejecta estimates (Housen et al., 1983; McGetchin et al., 1973; Petro and Pieters, 2008; Pike, 1974), or on radar and optical data (Blanchette-Guertin et al., 2012; Thompson et al., 2009). The estimates were, however, highly diverse ranging from a few hundreds of meters up to tens of kilometers.
The early impact bombardment extensively fractured the lunar crust resulting in the formation of the so-called megaregolith. Previous estimates of megaregolith distribution vary significantly with respect to the vertical extent and the size-frequency distribution of fragments was rarely studied. We built a spatially resolved numerical model to simulate the process of cumulative impact fragmentation, aiming to backtrack the megaregolith evolution history and to constrain its fragment distribution. The results highlight the pivotal role of basin-forming events on the megaregolith formation. Especially the South-Pole Aitken (SPA) impact established the initial megaregolith structure which remained distinct after 0.5 Ga subsequent fragmentation. At 3.8 Ga, the megaregolith displays substantial lateral variation and layering: the highly fractured upper layer of ∼2.5 km is dominated by meter-scale fragments; the disturbed lower layer deeper than tens of kilometers is mainly consisting of kilometer-scale fragments; the transition zone >5 km contains fragments of various size scales.
Formation age of lunar Lalande crater and its implications for the source region of the KREEP-rich meteorite Sayh al Uhaymir 169
2022, Icarus
As the most KREEP-rich lunar sample, the Sayh al Uhaymir (SaU) 169 meteorite would provide more valuable information concerning the KREEP and early lunar evolution of the Moon if its source regions can be pinpointed. Previous studies proposed Lalande crater as the source region that corresponds to the impact event of ~2.8 Ga recorded in SaU 169, whereas this linkage is highly dependent on the age determination of the potential source crater. By counting craters superposed on the ejecta blankets of Lalande and modelling the burial process of these superposed craters by Lalande's ejecta, we find that the crater statistics around Lalande are heavily influenced by the existing of pre-Lalande craters larger than ~170 m in diameter, which could lead to a largely overestimated age of Lalande crater. After taking this influence into consideration, we obtain that Lalande crater is a Copernican crater with a formation age of 410 ± 20 Ma, and the adjacent mare basalts unit has an Imbrian age of 3.8_−0.06^+0.04 Ga. The formation age of Lalande crater is inconsistent with any of the radio-isotopic ages recorded in SaU 169, indicating that Lalande crater is unlikely to be the source region of this lunar meteorite.
On the provenance of the Chang'E-5 lunar samples
2022, Earth and Planetary Science Letters
China's Chang'E-5 (CE-5) mission has collected 1.731 kg samples from a young mare basalt unit (named P58/EM4) in the northeastern Oceanus Procellarum region of the Moon. Accurate tracing of the provenance of returned samples is essential for understanding their laboratory measurements, which can provide critical information about the Moon and the inner Solar System. In this article, the provenance, chemical composition, formation, and evolution processes of the regolith at the CE-5 landing site are analyzed by using remote sensing observations and crater ejecta deposition models. A comprehensive search based on crater ejecta thickness model shows that 1892 impact craters in P58 likely deposited ∼0.56 m of primary ejecta at the landing site, whereas 4 impact craters outside P58 deposited 0.05 m of distal ejecta that further excavated and reworked ∼0.5 m thick local mare basalt. Twelve craters within 1 km from the CE-5 landing site are estimated to contribute ∼0.49 m (~88%) of the ejecta materials, and their ejecta source regions are investigated using the Maxwell Z model. Among these 12 craters, Xu Guangqi and a smaller crater near the landing site are the two most volumetrically significant contributors (~0.3 m and ∼0.12 m). Craters more than 1 km distant from the landing site deposited fewer exotic materials, but some of them could have delivered low-Ti materials to the sampling site. Finally, the regolith stratigraphy at the landing site is investigated based on the identified and assumed impact sequence by using a Monte Carlo-based ejecta ballistic sedimentation model. The results reveal a depth-varying FeO/TiO₂ abundance profile at the landing site, suggesting that the sedimentation of distant ejecta can reduce FeO/TiO₂ abundance of the underlying layer by ∼1 wt.% at ∼0.5 m depth. Our results provide key information on sample provenance and regolith stratigraphy of the landing site, which is crucial to deciphering the returned CE-5 samples.
Size–frequency measurements of meter-sized craters and boulders in the lunar polar regions for landing-site selections of future lunar polar missions
2022, Icarus
The concentrations of volatiles, especially hydrogen (or water), at the lunar poles have been reported from remote sensing data in previous studies. Many future missions are targeting to investigate the permanently shadowed regions inside polar craters, where water ice can exist because the temperature is extremely low. Accordingly, landing sites are being planned around polar craters. We conducted a geomorphological analysis of the ejecta blankets of Shackleton Crater at the South Pole (89.63°S, 130.0°E) and Whipple Crater at the North Pole (89.14 N°, 119.5°E). Size–frequency measurements of the craters and boulders were derived from high resolution (~1 m/pix) image data obtained by the Narrow Angle Camera onboard the Lunar Reconnaissance Orbiter. The number of identified craters (diameter > 10 m) and boulders (diameter > 3 m) were 35,799 and 1273, respectively, around Shackleton and 17,074 and 3092, respectively, around Whipple. The number densities of boulders around fresh craters on Shackleton and Whipple rim are lower than at the Apollo and Luna landing sites, suggesting a low production rate of boulders in these regions. The number density of small craters is lower than expected from the formation ages of Shackleton and Whipple and is strongly correlated with regional topographic slopes, implying that small craters were eliminated by resurfacing with mass wasting from the continuous ejecta of Shackleton and Whipple. Ejecta blankets from small craters may cover and preserve past subsurface accumulations of water molecules. Based on the crater counting data, we propose feasible landing sites around Shackleton Crater and scenarios for exploring local subsurface water using excavators in future missions.
Mass Movements Related with Impact Craters
2022, Treatise on Geomorphology
Collisions between celestial materials are a fundamental process in the formation and evolution of our Solar System and beyond. Craters formed by high-velocity impacts are the dominate landform across Solar System bodies that have solid surfaces. The general process and products of impact cratering are introduced, together with various forms of mass movements that are related with impact craters. Impact cratering introduces both surface topography and target heterogeneities, promoting the formation of mass movements over large areas and time scales. The combined effect of impact cratering and mass movements dominate the topographic evolution of most planetary bodies.
