'''Hydrogen''' is the simplest, lightest, and first element formed after the big bang.  It is the most common element, making up approx 90% of the universe by weight.  Hydrogen is one of the highly useful and necessary elements believed to be in critically short supply on Luna.  Its most common nuclear permutation (isotope) is a single proton, although it can also exist with one (deuterium) or two (tritium) neutrons.  On Earth, hydrogen is most commonly found combined with [[oxygen]] in the form of [[water]] (H<sub>2</sub>O).  The Moon is much smaller than Earth, hence its gravity is not strong enough to retain liquid oceans nor gaseous amtosphere; most of the volatiles of the Moon, including hydrogen, have long since evaporated and escaped into space.
 
  
−
Common uses of hydrogen which may be applied on the Moon include: rocket fuel, hydrogen fuel cells, [[ilmenite reduction]], [[reduction]] of metal ores and nitrogen fixation.
 
−
Deuterium/tritium can be as fuel used in nuclear fusion.
 
  
−
Hydrogen has possibly been detected at the Lunar poles, but the amount available has been a topic of controversy.
