Dawn Aerospace and Cosmoserve Space sign Strategic MoU to advance In-Space Refuelling
Cosmoserve and Dawn Aerospace MoU Signing in Bremen, Germany on 19th November at Space Tech Expo Europe 2025.
Bremen, Germany – 21th November 2025 — In a major step towards pushing for a more sustainable space environment, Dawn Aerospace and Cosmoserve Space have signed a Memorandum of Understanding to partner on enabling sustainable and scalable in-space servicing through refuelling and debris removal technologies.
The strategic MoU expresses both parties’ intent to explore future collaboration on integrating Dawn’s refuellable propulsion systems and in-space refuelling service; Loop, with Cosmoserve Space’s debris capture and removal missions.
This partnership is grounded in a shared vision to enable sustainable and scalable in-space servicing, ushering in a new era for the space industry.
“Replacing toxic hydrazine-based propulsion systems has been our first major step to allow more sustainable and scalable propulsion in space. However, to facilitate a fully sustainable space industry with in-orbit servicing, in-space refuelling is vital. This is why we are excited at the opportunity to work with Cosmoserve Space, as this is a key step towards enabling a circular space economy, where satellites and servicing vehicles can be refuelled and redeployed instead of replaced”, said Jeroen Wink, Co-founder and CRO of Dawn Aerospace.
Active debris removal represents one of the most complex challenges in space operations, requiring precise maneuvering, extended mission durations, and reliable propulsion systems. By combining Dawn Aerospace’s refuelling and propulsion capabilities with Cosmoserve Space’s debris-removal platforms, the partnership aims to enhance mission endurance and reduce the environmental impact of space activity.
“Dawn’s in-space propulsion solutions are a natural complement to our debris removal technology,” said Chiranjeevi Phanindra, Founder and CEO of Cosmoserve Space. “Through this collaboration, we can explore the utilization of Dawn’s systems in our in-space re-fueling depot – the Mothercraft for cost-effective and sustainable debris removal missions, ultimately helping preserve the usability of near-Earth space for future generations.”
The key focus area of the MoU includes the investigation of technical interfaces, operational synergies and potential future missions, using the core technologies of both companies.
About Dawn Aerospace
Dawn Aerospace is a space transportation company developing both refuellable satellite propulsion and the fastest, highest-flying spaceplane ever to take off from a runway. Dawn’s propulsion systems are already operating on 41 satellites and are designed to be refuelled in orbit via the company’s in-house developed docking and fluid transfer port. This capability tackles the long-standing “chicken-and-egg” problem of in-space refuelling by seeding the infrastructure that will form the backbone of a sustainable space industry. The next step is LOOP — an on-orbit refuelling network, revolutionising the sustainability and scalability of in-space mobility.
Their spaceplane, Aurora, combines the extreme performance of rocket propulsion with the reusability of conventional airplanes to enable high-frequency, low-cost access to suborbital space.
Founded in 2017, Dawn Aerospace has over 120 staff across offices in the Netherlands, France, New Zealand, and the United States.
About Cosmoserve Space
Cosmoserve Space is set to solve the global space debris crisis. With over 40,000 large uncontrolled objects in orbit, Cosmoserve develops autonomous robotic spacecraft—Reviver chaser and re-fuelling depot in space – Mothercraft—for cost-effective active debris removal and satellite end-of-life services. Using proprietary soft robotics for damage-free capture, the team targets in-space demonstration by late 2026, delivering scalable, world-class orbital sustainability solutions from India to the globe.
