Zhuque-2 is a Chinese medium-class orbital launch vehicle developed by LandSpace. It is a liquid-fuelled rocket powered by liquid oxygen and liquid methane (methalox), and is the first methane-fueled rocket to reach orbit.

The highest specific impulse chemical rockets use liquid propellants. They can consist of a single chemical or a mix of two chemicals, called bipropellants. Bipropellants can further be divided into two categories; hypergolic propellants, which ignite when the fuel and oxidizer make contact, and non-hypergolic propellants which require an ignition source.
