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 ...

Modeling the Evolution of Lunar Regolith: 2. Growth Rate and Spatial Distribution

Journal of Geophysical Research: Planets, 2023
The evolution of regolith thickness induced by continuous impact events on the lunar surface provides valuable information about lunar geology and the bombardment history of the inner Solar System.

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.

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.

Instrumental Neutron Activation Analysis of Chang'E-5 Lunar Regolith Samples.

Journal of the American Chemical Society, 2022
The Chang'E-5 (CE-5) lunar samples were analyzed nondestructively for more than 40 elements by instrumental neutron activation analysis (INAA) with a strict quality assurance and quality control.

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.
