space rockets use liquid oxidizer propellant as fuel.
what kind of fuel do space rockets use?
liquid oxidizer propellant
chemical rockets can be grouped by phase. solid rockets use propellant in the solid phase, liquid fuel rockets use propellant in the liquid phase, gas fuel rockets use propellant in the gas phase, and hybrid rockets use a combination of solid and liquid or gaseous propellants.
rocket propellant
chemical rockets are powered by exothermic reduction-oxidation chemical reactions of the propellant:





























bullet::::- solid-fuel rockets (or solid-propellant rockets or motors) are chemical rockets which use propellant in a solid phase.





























bullet::::- liquid-propellant rockets use one or more propellants in a liquid state fed from tanks.





























bullet::::- hybrid rockets use a solid propellant in the combustion chamber, to which a second liquid or gas oxidizer or propellant is added to permit combustion.





























bullet::::- monopropellant rockets use a single propellant decomposed by a catalyst. the most common monopropellants are hydrazine and hydrogen peroxide.
