Detailed explanation-1: -Hence, Hydrogen is used as a rocket fuel .
Detailed explanation-2: -Today, liquid hydrogen is the signature fuel of the American space program and is used by other countries in the business of launching satellites. In addition to the Atlas, Boeing’s Delta III and Delta IV now have liquid-oxygen/liquid-hydrogen upper stages.
Detailed explanation-3: -RP-1 (alternatively, Rocket Propellant-1 or Refined Petroleum-1) is a highly refined form of kerosene outwardly similar to jet fuel, used as rocket fuel. RP-1 provides a lower specific impulse than liquid hydrogen (LH2), but is cheaper, is stable at room temperature, and presents a lower explosion hazard.
Detailed explanation-4: -Liquid propellants separate fuel and oxidisers and the two are combined in a combustion chamber where they burn and are red out from the base of the rocket. More complex than solid fuel, the ability to control the ow of propellant means the engine can be throttled to a particular speed.
