The Pallas-1 ({{lang-zh|s=智神星一号}}) is a medium-lift orbital launch vehicle under development by Galactic Energy. It features seven Welkin engines burning RP-1 and liquid oxygen (kerolox) in its first stage.{{cite web |url=https://mp.weixin.qq.com/s?__biz=MzU2NzUzMzIzNQ==&mid=2247489281&idx=1&sn=98cf05fdd705189f354ec4a8037f711f&chksm=fc9a9cddcbed15cb91ea4c2bf53a6007aa5864e724b06b91d08e9db431089aab85183ea2d035&cur_album_id=2201845022742970369&scene=178&subscene=10000&clicktime=1712111321&enterid=1712111321&sessionid=0&ascene=7&fasttmpl_type=0&fasttmpl_fullversion=7144342-en_US-zip&fasttmpl_flag=0&realreporttime=1712111321904#rd |title=智神星一号液体运载火箭圆满完成控制系统半实物仿真试验 |date=23 February 2024 |access-date=3 April 2024}} The first stage will have legs and grid fins to allow for stage recovery by vertical landing (much like the SpaceX Falcon 9).{{cite web |last=Jones |first=Andrew |url=https://spectrum.ieee.org/galactic-energy-prepares-ceres1-rocket-first-launch |title=Galactic Energy Prepares Ceres-1 Rocket for First Launch |work=IEEE Spectrum |date=20 March 2020 |access-date=8 September 2021}}

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).{{cite web |last=Jones |first=Andrew |url=https://www.spacenews.com/chinese-private-firm-galactic-energy-puts-five-satellites-in-orbit-with-second-launch/ |title=Chinese private firm Galactic Energy puts five satellites in orbit with second launch |work=SpaceNews |date=7 December 2021 |access-date=7 December 2021}} The first launch of the rocket was scheduled to take place in November 2024,{{cite tweet |author=China 'N Asia Spaceflight |user=CNSpaceflight |number=1750630860821533069 |title=GALACTIC-ENERGY's CEO says Pallas-1 will be ready to launch this November. |date=25 January 2024}}{{needs update|date=January 2025}} while an initial attempt at first stage recovery using landing legs is slated for 2025.{{cite web |last=Jones |first=Andrew |url=https://spacenews.com/chinese-launch-startup-galactic-energy-raises-154-million-for-pallas-1-reusable-rocket/ |title=Chinese launch startup Galactic Energy raises $154 million for Pallas-1 reusable rocket launch |work=SpaceNews |date=20 December 2023 |access-date=20 December 2023}}

Using three Pallas-1 booster cores as its first stage, Pallas-1B ({{lang-zh|s=智神星一号乙}}) will be capable of putting a 17.5-tonne payload into low Earth orbit.
