Inflatable Atmospheric Decelerators (IADs)
- Founded just in October, Klaus’ aim is to make space transportation sustainable, available, and cost-efficient. The German company’s focus is on scalable cargo transport from space back to Earth without using any fuel.
- The drop-test demonstrated reliable inflation of the IAD and acceptable structural loads at landing, the company said. The third-generation prototype and an attached miniaturised rocket first stage were dropped from 600 m from a helicopter. The activated IAD stabilized and decelerated the rocket stage for safe landing in water and successful recovery afterwards.
- The company calls the opportunity “microgravity on demand,” a nascent market segment that has huge potential. Atmos’ service is tailored specifically for life sciences, according to the startup’s website, which can include research into monoclonal antibodies, stem cells, artificially grown human tissue, and protein crystallization.
- Investors appear to agree with Atmos’ approach, with the startup announcing this week that it has closed a €4 million ($4.3 million) oversubscribed seed round. The round was led by High-Tech Gründerfonds and the Amadeus APEX Technology Fund, with additional participation from Seraphim Space, E2MC, Ventis and another.vc.
- The company is developing a return capsule aptly named Phoenix, a spacecraft with a payload capacity of 100 kilograms. The Phoenix capsules are designed to operate on orbit for missions ranging from three hours to three months. Atmos has also developed what it calls “inflatable atmospheric decelerators” (IADs), a return solution that acts as both a heat shield, protecting the cargo from Earth’s atmosphere, and a high-velocity parachute.
Space Return Service
Based on our patent pending IAD technology, we are developing an end-to-end Space Return Service. We are offering our services in the form of early development partnerships with our customers. We tailor our IADs to the customer’s needs, from integration, tests and mission support, to the water landing and recovery. Whatever it is you want to bring down from space, we will do it for you. Safely.
HyImpulse Delivers Primary Structure and Components for ATMOS’ PHOENIX Return Vehicle, 2025-03-27.
- Structural manufacturing, and integration of critical components for the PHOENIX 1 return vehicle.
- HyImpulse supported both the design of the fluid system and structural elements of the PHOENIX vehicle.
- Manufacturing key structural components in-house. The company produced a full-scale engineering model in 2023, followed by the flight hardware in mid-2024. The manufacturing process involved the hand-laminating of key structural parts of the payload and equipment bay.
- Responsible for the engineering and assembly of the Ballute Inflation System for PHOENIX. This fluid system is designed to initially pressurize and inflate the vehicle’s inflatable heat shield using gaseous nitrogen at controlled mass flows.
PHOENIX 1 Protoflight Mission Update: Re-entry Trajectory Change, 2025-04-18.
- Initial analysis confirms that the mission achieved its primary objectives, including the activation of key systems and deployment of ATMOS’ proprietary inflatable heat shield under realistic re-entry conditions.
- These findings add critical information early to the already started development of the next-generation PHOENIX 2 capsule, which is planned to launch in 2026.
- On its first mission, PHOENIX 1 was also carrying commercial and scientific payloads for early-stage microgravity testing, including biological experiments and technological demonstrators from:
- Data from the final stage of descent could not be retrieved.
- PHOENIX will serve as an active orbital depot, able to precisely deploy ARX's and its partners’ autonomous systems within minutes, ensuring unmatched response times anywhere on the planet.
- With its modular platforms and software-defined architecture, ARX enables flexible, mission-specific deployment – now extended to orbital operations.
Status Comment
A partially successful first mission in April 2025. The structures and inflatable head shield were built by HyImpulse.
Notes
- SPiN is excited to work with ATMOS Space Cargo getting ready for the mission launching in 2024! 2 MA61C cubesats will enable a modular avionic stack, functioning as On Board Computer (OBC) and Remote Terminal Unit (RTU) in return service missions.
