The Pallas-1 is a medium-lift orbital launch vehicle under development by Galactic Energy of China.[1]

It will use RP-1 and liquid oxygen (kerolox) in its first stage. The first stage will have seven variable thrust engines, legs and grid fins to allow recovery by vertical landing (much like the SpaceX Falcon 9).[1] The first launch is scheduled to take place in 2023.[2][3]

The booster will use seven new 40-ton variable thrust ‘Cangqiong’ (Welkin) engines.[1]

It is planned to be able to put 4 tonnes into low Earth orbit (LEO), or 2 tonnes into sun-synchronous orbit (SSO).[1][4]

An upgraded variant of the rocket, Pallas-2, is currently under development. Using three Pallas-1 booster cores as its first stage, Pallas-2 will be capable of putting 14 tonnes into low Earth orbit.[5]
