The technology of lunar regolith environment construction on Earth

Acta Astronautica, 2021
Lunar regolith plays an extremely important role in the establishment of permanent human residence or robotic industries on the Moon. Lunar regolith environment construction may accelerate the progress of lunar engineering, biology, medicine, and ...

Solar 3D printing of lunar regolith

Acta Astronautica, 2018
The authors demonstrated the feasibility of sintering lunar regolith layer-by-layer solely using concentrated sunlight. First trials using actual concentrated sunlight led to an inhomogeneous sintering of individual layers of lunar regolith simulant, due

The Evolution of the Lunar Regolith

Annual Review of Earth and Planetary Sciences, 1977
layer (regolith) was known long before the first soft landings, though its properties were not clearly understood. Nearly all our present knowledge derives from samples returned from the Moon, and secondarily from observations made on the surface or from lunar orbit.

Discovery of Vapor Deposits in the Lunar Regolith

Science, 1993
Lunar soils contain micrometer-sized mineral grains surrounded by thin amorphous rims. Similar features have been produced by exposure of pristine grains to a simulated solar wind, leading to the widespread belief that the amorphous rims result from radiation damage. Electron microscopy studies show, however, that the amorphous rims are compositionally

Properties of Lunar Regolith

1990
Abstract The lunar regolith consists of the fragmental unconsolidated mantle which overlies more consolidated or crystalline rocks at the surface of the moon. The thickness of the regolith ranges from a few meters in some areas overlying mare basalt flows to tens of meters over much of the highland terrain.

Heterogeneous Weathering Process of Lunar Regolith Revealed by Polarimetric Attributes Analysis of Chang’E‐4 Lunar Penetrating Radar Data Acquired During the Yutu‐2 Turnings

Geophysical Research Letters, 2022
This paper provides analyses to quantify the maturity of regolith within 24 m depth using a novel polarimetric attributes analysis of lunar penetrating radar (LPR) data.

Higher water content observed in smaller size fraction of Chang'e-5 lunar regolith samples.

Science Bulletin
Water has been detected in lunar regolith, with multiple sources identified through the analysis of individual grains. However, the primary origin of water in the bulk lunar regolith remains uncertain.

The porosity of the upper lunar regolith

Icarus, 2016
Abstract The porosity of the upper centimeter or so of the lunar regolith strongly affects several properties that are commonly studied remotely. Hence, it is important to determine its value. We have reanalyzed the data of Ohtake et al. (Ohtake et al. [2010]. Space Sci.

On the depth of the lunar regolith

The Moon, 1970
The aim of this paper is to point out that if the sinuous rilles on the Moon represent trenches in the mare ground in which they meander, the existence of a great number of individual boulders on their slopes - as discovered on the high-resolution photographs taken by US Lunar Orbiters 4 and 5 in 1967 - suggests that the solid substrate of the lunar ...
