Cost of spaceflight

This is a comparison of orbital launch systems. The following exposes the full list of conventional orbital launch systems. For the short simple list of conventional launcher families, see: Comparison of orbital launchers families.

Spacecraft propulsion is any method used to accelerate spacecraft and artificial satellites. A conventional solid rocket or a conventional solid-fuel rocket is a rocket with a motor that uses solid propellants (fuel/oxidizer).Orbital launch systems are rockets and other systems capable of placing payloads into or beyond Earth orbit. All current spacecraft use conventional chemical rockets (bipropellant or solid-fuel) for launch, though some have used air-breathing engines on their first stage.

The following chart shows the number of launch systems developed in each country, and broken down by operational status. Rocket variants are not distinguished, i.e. the Atlas V series is only counted once for all its configurations 401–431, 501–551, 552 and N22.
