This comparison of orbital launch systems lists the attributes of all current and future individual rocket configurations designed to reach orbit. A first list contains rockets that are operational or have attempted an orbital flight attempt as of 2024; a second list includes all upcoming rockets. For the simple list of all conventional launcher families, see: Comparison of orbital launchers families. For the list of predominantly solid-fueled orbital launch systems, see: Comparison of solid-fueled orbital launch systems.

Falcon 9 Block 5, the most prolific active orbital launch system in the world.

Spacecraft propulsion[note 1] is any method used to accelerate spacecraft and artificial satellites. Orbital launch systems are rockets and other systems capable of placing payloads into or beyond Earth orbit. All launch vehicle propulsion systems employed to date have been chemical rockets falling into one of three main categories:

  • Solid-propellant rockets or solid-fuel rockets have a motor that uses solid propellants, typically a mix of powdered fuel and oxidizer held together by a polymer binder and molded into the shape of a hollow cylinder. The cylinder is ignited from the inside and burns radially outward, with the resulting expanding gases and aerosols escaping out via the nozzle.[note 2]
  • Liquid-propellant rockets have a motor that feeds liquid propellant(s) into a combustion chamber. Most liquid engines use a bipropellant, consisting of two liquid propellants (fuel and oxidizer) which are stored and handled separately before being mixed and burned inside the combustion chamber.
  • Hybrid-propellant rockets use a combination of solid and liquid propellant, typically involving a liquid oxidizer being pumped through a hollow cylinder of solid fuel.

All current spacecraft use conventional chemical rockets (solid-fuel or liquid bipropellant) for launch, though some[note 3] have used air-breathing engines on their first stage.[note 4]

    Notes

    1. [N 1]
      There are many different methods. Each mestylethod has drawbacks and advantages, and spacecraft propulsion is an active area of research. However, most spacecraft today are propelled by forcing a gas from the back/rear of the vehicle at very high speed through a supersonic de Laval nozzle. This sort of engine is called a rocket engine.
    2. [N 2]
      The first medieval rockets were solid-fuel rockets powered by gunpowder; they were used by the Chinese, Indians, Mongols and Arabs, in warfare as early as the 13th century.
    3. [N 3]
      Such as the Pegasus rocket and SpaceShipOne.
    4. [N 4]
      Most satellites have simple reliable chemical thrusters (often monopropellant rockets) or resistojet rockets for orbital station-keeping and some use momentum wheels for attitude control. Soviet bloc satellites have used electric propulsion for decades, and newer Western geo-orbiting spacecraft are starting to use them for north–south stationkeeping and orbit raising. Interplanetary vehicles mostly use chemical rockets as well, although a few have used ion thrusters and Hall effect thrusters (two different types of electric propulsion) to great success.
