Lunar soil simulants alter macrophage survival and function
Journal of Applied Toxicology, 2019Lunar regolith samples collected during previous Apollo missions were found to contain components that were established to be toxic to humans; however, the health effects due to inhalation of lunar soil as a whole are still unknown.

Surface history of lunar soil and soil columns
Geochimica et Cosmochimica Acta, 1974Measurements of cosmic ray track densities are presented for soil samples from Apollo 15, 16, and 17. Median track densities are used to infer total effective exposure times within about 15 cm of the lunar surface. Minimum track densities are used to derive the time of the last impact-produced rearrangement of soil grains.

Icarus, 1967
Abstract Recent laboratory experimental evidence concerning the photometric properties of the lunar surface materials, as well as the Surveyor I photographs, have thrown considerable doubt on the highly underdense, “fairy castle” model of the uppermost lunar surface layer.

SAE Technical Paper Series, 1996
<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.

Lunar problems in soil engineering
Journal of Terramechanics, 1965In the relatively near future unmanned, and perhaps manned spacecraft will make soft landings on the moon, and ultimately on some of the other planets. Because our knowledge of the intimate small-scale properties of the lunar surface is almost nonexistent, it is desireable to devise surface models and materials in line with current information for the ...

Accumulation of Carbon in Lunar Soils
Nature Physical Science, 1973Analyses of the carbon compounds released by pyrolysis from size fractions and particle separates of lunar soils indicate that the rate at which extralunar carbon is accumulated is slow compared to the rate at which it is redistributed among the different particle types by the cycle of particle erosion and aggregation.

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
