Lunar-forming impacts: processes and alternatives [PDF]

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2014
The formation of a protolunar disc by a giant impact with the early Earth is discussed, focusing on two classes of impacts: (i) canonical impacts, in which a Mars-sized impactor produces a planet–disc system whose angular momentum is comparable to that in the current Earth and Moon, and (ii) high-angular-momentum impacts, which produce a system whose ...

Analyzing LDEX's Current Measurements in Lunar Orbit

The Planetary Science Journal, 2023
The Lunar Dust Experiment (LDEX) on board the Lunar Atmosphere and Dust Environment Explorer mission orbited the Moon from 2014 September to 2015 April and observed a dynamic, permanently present dust cloud produced by continual meteoroid bombardment. In

Latitude Variation of Flux and Impact Angle of Asteroid Collisions with Earth and the Moon

The Planetary Science Journal, 2021
Flux and impact angles were calculated for asteroid collisions with Earth and the Moon, using the latest population models for the distribution of near-Earth objects (NEOs) and precession models to determine the impact probabilities.

Orbit Design for LUMIO: The Lunar Meteoroid Impacts Observer

Frontiers in Astronomy and Space Sciences, 2018
The Lunar Meteoroid Impacts Observer, or LUMIO, is a space mission concept awarded winner of ESA's SysNova Competition “Lunar CubeSats for Exploration,” and as such it is now under consideration for future implementation by the Agency.

Performance of Lunar Regolith Shield under Meteoroid Impact: Uncertainties of a Numerical Prediction

Applied Sciences, 2022
The protection of the future lunar base from radiation, thermal stresses and impacts of meteoroids can be achieved by several options, generally consisting in a shielding system, made of either regolith or combined materials.

Recognition of landslides in lunar impact craters [PDF]

European Journal of Remote Sensing, 2017
Landslides have been observed on several planets and minor bodies of the solar System, including the Moon. Notwithstanding different types of slope failures have been studied on the Moon, a detailed lunar landslide inventory is still pending. Undoubtedly, such will be in a benefit for future geological and morphological studies, as well in hazard, risk

Physical Characterization of Moon Impactor WE0913A

The Planetary Science Journal, 2023
On 2022 March 4, the object known as WE0913A crashed into the Moon after several close flybys of the Earth and the Moon in the previous three months. Leading up to impact, the identity of the lunar impactor was up for debate, with two possibilities: the ...

Crustal Porosity of Lunar Impact Basins [PDF]

Journal of Geophysical Research: Planets, 2020
AbstractLateral variations in bulk density and porosity of the upper lunar highland crust are mapped using a high‐resolution Gravity Recovery and Interior Laboratory (GRAIL) gravity field model and Lunar Reconnaissance Orbiter (LRO) derived topography.

Potent Liver‐Tropic mRNA Lipid Nanoparticles: ApoE‐Mediated Delivery Through a Low‐Density Lipoprotein Receptor Independent Uptake Mechanism

Advanced Materials, EarlyView.
Helper and ionizable lipids play a crucial role in determining ApoE binding and subsequent liver tropism and LDLR‐mediated uptake. Ionizable lipids primarily govern the LDLR‐independent uptake pathway. This complementary interplay between lipid components ultimately governs LNP delivery performance and therapeutic efficacy in the liver.

The Composition and Stratigraphy of the Chang’e-6 Landing Mare

The Planetary Science Journal
China’s Chang’e-6 (CE-6) mission returned lunar samples from the southern mare in the Apollo basin formed in the prominent South Pole–Aitken basin. The basic geological context of the landing mare has been well resolved.
