Evaluations of lunar regolith simulants

Planetary and Space Science, 2016
Apollo lunar regolith samples are not available in quantity for engineering studies with In-Situ Resource Utilization (ISRU). Therefore, with expectation of a return to the Moon, dozens of regolith (soil) simulants have been developed, to some extent a result of inefficient distribution of NASA-sanctioned simulants.

Lunar surface: Dust dynamics and regolith mechanics

Reviews of Geophysics, 2007
The lunar surface is characterized by a collisionally evolved regolith resulting from meteoroid bombardment. This lunar soil consists of highly angular particles in a broad, approximately power law size distribution, with impact-generated glasses.

Predicting residual friction angle of lunar regolith based on Chang'e-5 lunar samples.

Science Bulletin, 2023
With the rapid development of human lunar exploration projects, the lunar base establishment and resource utilization are on the way, and hence it is urgent and significant to reasonably predict engineering properties of the lunar regolith, which remains

Statistical estimates of rock-free lunar regolith thickness from diviner

Planetary and Space Science, 2023
Introduction: With virtually no atmosphere, the moon preserves evidence on its surface that has implications for remote sensing studies [1], subsurface volatile research [2], and landing site determination [3].

Contaminants in the Lunar Regolith

Астрономический вестник, 2023
The lunar regolith delivered to Earth in the 1970s by the Soviet automatic stations Luna-16, -20, and -24, despite the small amount of material, is of great value for science and requires careful study. How ever, since soil samples have gone quite a long way from the moment of extraction to direct examination, there is a danger of possible ...

Lunar Regolith at Tranquillity Base

Science, 1970
The regolith at Tranquillity Base is a layer of fragmental debris that ranges in thickness from about 3 to 6 meters. The thickness of the regolith and the exposure histories of its constituent fragments can be related, by means of a relatively simple model, to the observed crater distribution.

The Nature of Volatiles in the Lunar Regolith

Solar System Research, 2002
Layer-by-layer analysis of the fine fraction of Luna-16 sample L1635 by X-ray photoelectron spectroscopy (XPS) revealed a zonal structure of its constituent particles. The outer zone, to a depth of 1200 A, is enriched with Si and Fe and depleted in refractory elements Mg, Ca, and Al as compared to the bulk composition of the sample. The second zone, in

Hyperfine Structure of Regolith Unveiled by Chang’E-5 Lunar Regolith Penetrating Radar

IEEE Transactions on Geoscience and Remote Sensing, 2022
This work presents the results of the Lunar Regolith Penetrating Radar (LRPR), installed at the bottom of the Chang’E-5 (CE-5) lander, which is the first antenna-array radar deployed for the investigation of an extraterrestrial body.
