This article lists all active and upcoming orbital launch systems. For retired launch vehicles, see Comparison of retired orbital launch systems.
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.
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:
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]
