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.

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.

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.

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 ...

Thermophysical Analysis of Regolith on (101955) Bennu: The Coarse Regolith Conundrum

Thermophysical analyses of planetary bodies such as the Moon, Mars, and numerous asteroids have allowed for remote estimates of regolith physical properties, such as particle size and packing density, as well as the relative spatial abundance of boulders.  Here we define “regolith” as a particulate assemblage where most ...
