Featured article: Helium
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)
