ATMOS Space Cargo: €25.7M for European Sovereign Orbital Return Capability

ATMOS Space Cargo, a European company specializing in the development of orbital transport and re-entry vehicles, has announced the closing of a €25.7 million Series A financing round. This strategic investment is aimed at strengthening Europe's autonomous return-from-orbit capability, a growing need for both the commercial and defense sectors.

The funds raised will be used for the construction of an initial fleet of three PHOENIX 2 vehicles, the launch of ATMOS WORKS – an entity dedicated to governmental and defense clients – and the development of PHOENIX 3, the company's next-generation orbital return vehicle. The primary goal is to transform orbital re-entry from an occasional operation into a repeatable and reliable European service, ensuring autonomy and control.

PHOENIX: Technology for Precise and Sustainable Re-entry

The PHOENIX 2 is a free-flying spacecraft designed to operate in Low Earth Orbit (LEO) for missions lasting from hours to several months. Equipped with integrated propulsion and power systems, the vehicle is capable of autonomous de-orbit maneuvers and controlled atmospheric re-entry. This is made possible by ATMOS's Inflatable Atmospheric Decelerator (IAD) technology, which serves as both a heat shield and an aerodynamic brake.

The non-ablative design of the IAD minimizes material loss and environmental impact while maximizing payload-to-mass efficiency and re-entry precision for rapid payload recovery. Three PHOENIX 2 orbital transfer and return vehicles (OTRVs) will be constructed and operated as a phased operational mission campaign, servicing institutional and commercial clients across a range of payload and mission profiles. Initial recovery operations are being prepared near Santa Maria in the Azores, under Portugal’s ANACOM-09/2026-AE licence, enabling commercial orbital re-entry operations under a continental European Union member state’s jurisdiction. In parallel, ATMOS has begun development of PHOENIX 3, a next-generation orbital transfer and re-entry vehicle designed for a payload capacity of approximately one metric tonne – roughly ten times that of the PHOENIX 2.

ATMOS WORKS: Sovereignty and Security for the Public Sector

The launch of ATMOS WORKS represents a significant step for ATMOS Space Cargo. This new entity will focus on space logistics and operational capabilities specifically for European governmental and defense customers. The PHOENIX platform’s dual-use architecture supports a wide range of mission profiles, including in-orbit demonstration and validation (IOD/IOV), secure and sovereign return of sensitive hardware and data, and responsive time-critical operations.

For organizations operating with AI/LLM workloads, the issue of data sovereignty and control over infrastructure is paramount. Similar to the need to keep sensitive data within specific jurisdictional boundaries or on self-hosted and air-gapped infrastructures, the ability to autonomously and securely retrieve hardware and data from orbit is crucial for national security and the protection of critical information. This approach reduces dependence on external providers and ensures that European space operations are managed with the highest level of control and compliance.

Future Prospects and Strategic Autonomy

The funding round was co-led by Balnord and Expansion, joined by Keen Defence and Security and the European Innovation Council (EIC) Accelerator program, which combines grant and equity components. Additional investors include OTB Ventures, High-Tech Gründerfonds (HTGF), APEX Ventures, Seraphim, Faber, E2MC, Kirch Ventures, Lennertz & Co., Mätch VC, MBG Baden-Württemberg, and Tech Horizons.

Sebastian Klaus, CEO and co-founder of ATMOS Space Cargo, emphasized how this financing allows the company to move to regular operational service. “A structured campaign of three vehicles establishes Europe’s first routine orbital return infrastructure,” Klaus stated. “PHOENIX 2 is the first step to build a scalable European return infrastructure that will demonstrate our ability to access, operate, and return materials, data, and hardware from orbit independently. With ATMOS WORKS and PHOENIX 3, we are building the full architecture – commercial, institutional, and defense-capable – in parallel.” Aleksander Dobrzyniecki, General Partner at Balnord, added that ATMOS is building exactly the kind of dual-use capability Europe needs: sovereign access not only to orbit, but back from orbit, contributing to a real European space industrial base built on operational services and strategic autonomy.
