[[Image:Apollo11Soil.jpg|160px|left]] The primary resource of value to humans on the Moon is the volatile components found in the [[regolith]]. These are all the components that are gases at room temperature. Most of the volatiles have been deposited in the top layers of the Moon's surface by the [[solar wind]] over geologic time. A notable exception to this is [[Argon]]. the concentration of Argon in lunar soil is much higher than found in the solar wind, so must come from a different source. Especially, the isotope Argon-40. It is presently believed that the Argon-40 comes from radioactive decay of [[Potassium]] and/or [[Krypton]] deep within the lunar mantle or core([[Volatiles|read more]])

JSC-1, a lunar soil simulant, was developed and characterized under the auspices of the NASA Johnson Space Center. This simulant was produced in large quantities to satisfy the requirements of a variety of scientific and engineering investigations. JSC-1 is derived from volcanic ash of basaltic composition, which has been ground, sized, and placed into storage. The simulant's chemical composition, mineralogy, particle size distribution, specific gravity, angle of internal friction, and cohesion have been characterized and fall within the ranges of lunar mare soil samples. ...(read more)
