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 ...

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.

Simulating Martian regolith in the laboratory

Planetary and Space Science, 2008
Abstract Regolith and dust cover the surfaces of the Solar Systems solid bodies, and thus constitute the visible surface of these objects. The topmost layers also interact with space or the atmosphere in the case of Mars, Venus and Titan. Surface probes have been proposed, studied and flown to some of these worlds.

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 analysis of water in the Martian regolith

Journal of Molecular Evolution, 1979
One of the scientific objectives of the Viking Mission to Mars was to accomplish an analysis of water in the Martian regolith. The analytical scheme originally envisioned was severely compromised in the latter stages of the Lander instrument package design. Nevertheless, a crude soil water analysis was accomplished.

The regolith in Australia

Earth-Science Reviews, 1988
Abstract Australian regolith materials are described, many of which are complex. Much Australian regolith dates back to the Tertiary, Mesozoic or earlier. There is a progressive change in the nature of alluvium through the Tertiary. Aridity, revealed through sand dunes and evaporites, is confined to the Quaternary.

Rock to regolith

Nature Geoscience, 2010
The amount of pore space in most unweathered granite is too small to support a plant-based ecosystem. But porosity grows as intact rock interacts with surface waters beneath the soil.

Surface regolith and environment of comets

Planetary and Space Science, 1994
Abstract A model for the formation of regolith at cometary surfaces is proposed which is based on the observational fact that comet nuclei release particles with sizes in the micrometre to the decimetre range. The particle emission mechanism is appropriated not only to accelerate particles to escape velocity, but also to “launch” them into orbits ...

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.
