Associated Propellants
  • Lox/LNG Liquid oxygen was the earliest, cheapest, safest, and eventually the preferred oxidiser for large space launchers. Its main drawback is that it is moderately cryogenic, and therefore not suitable for military uses where storage of the fuelled missile and quick launch are required. Liquefied natural gas - mainly methane,with traces of sulfur, etc. More...
