HAN (hydroxylammonium nitrate)
A relatively new, synthetic, rocket fuel with the chemical formula NH2OH+NO3.
HAN has the potential to be used both as a liquid monopropellant
and an ingredient in solid propellants. It has the advantage of being more
environmentally friendly than the toxic hydrazine
presently used in thrusters on most spacecraft
