星河动力空间科技有限公司 Galactic Energy- Galaxy Power (Beijing) Space Technology Co., Ltd.Located in Block D, Aviation Technology Plaza, E-Town, and Beijing – Beijing – China – People’s Republic of China ….Galaxy Aerospace is the first private aerospace company in China to achieve successful continuous launches, the first to send commercial networked satellites into a 500km sun-synchronous orbit, and the first to master the ability to launch multiple satellites with one carrier rocket
Galaxy Aerospace prepares to launch two rockets, aiming for full launch capability.
As 2025 approaches its fourth quarter, Galaxy Aerospace has reached a significant milestone in its launch vehicle development: the maiden flights of its Ceres-2 and Pallas-1 rockets have entered a critical phase, with engine delivery and final assembly recently underway, laying a solid foundation for their maiden flights.
Ceres-2, poised for launch!
The Ceres-2 launch vehicle recently completed all ground development and verification work and entered the final assembly phase, nearing its maiden flight.
Ceres-2 is an upgraded version of the Ceres-1, featuring a three-stage solid-fuel tandem rocket and a liquid upper stage. With a takeoff mass of 100 tons, it boasts a 500km LEO payload capacity of 1.6 tons and a 500km SSO payload capacity of 1.3 tons, achieving a payload efficiency of 1.3%, reaching internationally leading levels.
Ceres- 2 supports launches from a variety of platforms, both land and sea. While maintaining flexibility and rapidity, it significantly reduces launch costs through technological innovation and system optimization, bringing the unit price to comparable levels with a 200-ton medium-sized liquid rocket.
Recently, the CQ-50 liquid oxygen/kerosene engine independently developed by Galaxy Power Aerospace Corporation has completed mass production, assembly, testing, process trials, and post-test preparations for the Ceres-1 rocket. The engine has been officially delivered for final assembly and testing of the first and second stage systems, as well as the Yao-1 flight test, for the Ceres-1 rocket.
To date, the company has assembled, tested, and delivered over 30 engines, with cumulative test duration exceeding 10,000 seconds, with individual engines exceeding 2,000 seconds. This marks significant progress in the reliability and industrialization of the CQ-50 liquid oxygen/kerosene engine.
The CQ-50 liquid oxygen/kerosene engine is a 50-ton thrust, open-cycle, reusable, variable-thrust rocket engine developed entirely independently by Galaxy Aerospace. It utilizes innovative design technologies, including a high-performance pintle-type injector thrust chamber, a coaxial split double-suction high-speed turbopump, and a spherical-conical multi-recirculating vortex gas generator. Its sea-level specific impulse exceeds 265 seconds. Its manufacturing process utilizes extensive 3D printing and highly integrated processes. The engine features low cost, continuously variable thrust, reusability, and multiple starts, and has passed numerous ground-fire tests.
The Pallas-1 is a two-stage liquid-propellant launch vehicle, primarily targeted at large constellation networks and large satellite launch markets. The first stage utilizes seven CQ-50 engines in parallel, with an optional Eros upper stage. With a takeoff mass of approximately 283 tons and a low-orbit payload capacity of 7 tons, it can meet the requirements for vertical recovery and reuse of the substage. From the large-
scale
commercial launch of Ceres-1 to the accelerated development of the CQ-90 100-ton liquid oxygen/kerosene engine, the main propulsion system for Pallas-2, and the upcoming maiden flights of Ceres-2 and Pallas-1, Galaxy Power Aerospace has built a complete technology system and product matrix within the 300kg to 58t payload capacity range. This will provide more diverse, flexible, and efficient launch services for China’s commercial space launch market, further support the needs of large-scale constellation networking, and help enhance the international competitiveness of China’s commercial space industry .
