As the low Earth orbit constellation satellite market expands, Korean space propulsion system company Space Solution has joined hands with European space company ArianeGroup.

Space Solution announced that on the 6th (local time), it signed a memorandum of understanding (MOU) with ArianeGroup GmbH in the field of satellite chemical propulsion systems at the venue of the “IAC 2026 World Space Congress.” Attending the signing ceremony were Lee Jae-heon, CEO of Space Solution; Stephan Ziegenhagen, Head of Orbital Systems, Equipment & Services at ArianeGroup; and Timo Korne, Senior Business Development Manager.

The two companies will pursue cooperation in the design, manufacturing, testing, and quality assurance (QA) of propulsion systems for low Earth orbit constellation satellites. By combining precision component manufacturing technologies with system integration experience, they plan to optimize processes and enhance product reliability and production efficiency, thereby strengthening their competitiveness in global supply.

Space Solution develops and manufactures space propulsion systems, attitude control systems, and special valves such as cryogenic valves. The company stated that it is building an in-house production system that covers the entire process from research and development (R&D) to manufacturing, assembly, and testing.

ArianeGroup is a space company based in France and Germany, conducting research and development on upper stages of launch vehicles, combustion chambers, cryogenic valves, and satellite propulsion systems at its facilities in Bremen, Ottobrunn, and Lampoldshausen in Germany.

Representatives of the two companies said, “This agreement is a starting point for combining the technologies and competitiveness of both companies in the low Earth orbit constellation satellite market,” adding, “We will continue to work together to supply propulsion systems with strong competitiveness to global customers.”
