<div class="htmlview paragraph">We have conducted experiments on 16 lunar soils and 3 lunar volcanic glass samples to study the extraction of oxygen, an important resource for future lunar bases. The samples were chosen to span the range of composition and mineralogy represented in the Apollo collection.

Journal of Terramechanics, 1964
The great research effort that has been mobilized to attempt solution of lunar exploration problems involving properties of soils and rocks on the Moon is summarized and reviewed. Current (1963) research activity has been examined within the framework of five categories: (1) Exploration and mapping of the lunar surface; (2) lunar soil formation and the

Abstract Because the lunar soil is darker than its parent rocks, it is often assumed that some process such as radiation darkening must have affected it. It is shown that the unusually high opaque mineral content of lunar rocks alone could account for the generally low albedo of the soil.

Lunar Soil Simulants- An Assessment
2019 9th International Conference on Recent Advances in Space Technologies (RAST), 2019In this study an assessment is done about lunar soil simulants. It is found that until now more than 40 simulants are produced in 9 countries. This procedure is a still ongoing one, after its start in the year 1990. The list of the simulants produced given in the paper is the most comprehensive one and it includes not only all of the types given in ...

Abstract:Two new lunar mare soil simulants, NAO‐2 and NAO‐3, have been created in National Astronomical Observatories (NAO), Chinese Academy of Sciences. These two simulants were produced from low‐titanium basalt and high‐titanium basalt respectively. The chemical composition, mineralogy, particle size distribution, density, angle of internal friction,

PREVIOUS models of the lunar surface layer have necessarily been constructed on the basis of indirect evidence, such as the way in which the surface reflected sunlight and radar pulses, or the manner in which it cooled during an eclipse. The photometric properties, in particular, have been utilized in model construction, because they were considered to

Reviews of Geophysics, 1975
The moon is covered with a thin layer of unconsolidated debris called the lunar regolith. A typical sample of this regolith could be characterized as a gray, poorly sorted pebble‐ or cobble‐bearing silty sand having a bulk density of about 1.5 g/cm³. It consists of lithic and mineral fragments mostly from the local underlying bedrock and glass formed ...

Abstract Lunar soil simulant is a geochemical reproduction of lunar regolith, and is needed for lunar science and engineering researches. This paper describes a new lunar soil simulant, CAS-1, prepared by the Chinese Academy of Sciences, to support lunar orbiter, soft-landing mission and sample return missions of China’s Lunar Exploration Program ...

Journal of the Soil Mechanics and Foundations Division, 1973
The index properties of returned lunar soils from the United States Apollo and the Soviet Luna programs are reviewed. The scope of the paper includes lunar soil genesis, particle types, grain size distribution, grain shape distribution, specific gravity, minimum and maximum density, and relative density.

The Remanent Magnetization of Lunar Soils
Science, 1972The magnetic material in the lunar soils makes them potentially strong carriers of remanence and magnetically viscous. The soils therefore block remanence in the temperature range of the lunar diurnal cycle. This remanence is stable against alternating-field demagnetization.
