The Nature of Volatiles in the Lunar Regolith
Solar System Research, 2002Layer-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

Surface regolith and environment of comets
Planetary and Space Science, 1994Abstract 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 ...Andrew Ryan +12 more
