[[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]])

He-3 T620 01.svg

Helium is a component of the solar wind, and hence is one of the volatiles found (in parts per million level) in Lunar regolith. It is a Noble gas in group 18 and is the second element in the Periodic Table of the Elements. This element has two stable isotopes: 3 and 4.

Helium 3 is a rare isotope of the element Helium, consisting of a nucleus with two protons and one neutron.

It has been proposed that 3He might be a possible fuel for a Nuclear Fusion reactor to produce energy using the thermo-nuclear reaction (Deuterium-Helium-3):

2H + 3He --> 4He + 1H+

This reaction has the advantage over the more-commonly proposed Deuterium-Tritium fusion reaction...(read more)
