HAN (hydroxylammonium nitrate)
HAN (hydroxylammonium nitrate) is 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
