Pallas-1

The Pallas-1 (Chinese: 智神星一号) is a medium-lift orbital launch vehicle under development by Galactic Energy.[2] It features seven new 40-ton variable thrust Welkin engines burning RP-1 and liquid oxygen (kerolox) in its first stage. The first stage will also have legs and grid fins to allow recovery by vertical landing (much like the SpaceX Falcon 9).[2] The first launch is scheduled to take place in 2024.[1]

Pallas-1 is planned to be capable of placing a 5-tonne payload into low Earth orbit (LEO), or a 3-tonne payload into a 700-kilometer sun-synchronous orbit (SSO).[2][3][4] An upgraded variant of the rocket, Pallas-2 (Chinese: 智神星二号), is currently under development. Using three Pallas-1 booster cores as its first stage, Pallas-2 will be capable of putting a 14-tonne payload into low Earth orbit.[5]
