The Surface Chemical Composition of Lunar Samples and Its Significance for Optical Properties [PDF]

open access: yes
The surface iron, titanium, calcium, and silicon concentration in numerous lunar soil and rock samples was determined by Auger electron spectroscopy. All soil samples show a large increase in the iron to oxygen ratio compared with samples of pulverized ...

Experimental Investigation of Soil Adsorption Effects on Water Migration in Simulated Lunar Conditions

open access: yesThe Planetary Science Journal
Adsorption is a key mechanism governing water vapor diffusion in lunar regolith. To investigate this process, we conducted experiments under simulated lunar conditions—Knudsen diffusion conditions—using three soil types with varying water vapor ...

Electrolysis of simulated lunar melts [PDF]

open access: yes
Electrolysis of molten lunar soil or rock is examined as an attractive means of wresting useful raw materials from lunar rocks. It requires only hat to melt the soil or rock and electricity to electrolyze it, and both can be developed from solar power ...

Resources for a lunar base: Rocks, minerals, and soil of the Moon [PDF]

open access: yes
The rocks and minerals of the Moon will be included among the raw materials used to construct a lunar base. The lunar regolith, the fragmental material present on the surface of the Moon, is composed mostly of disaggregated rocks and minerals, but also ...
