Space logistics for microgravity research & commercial space. Reusable capsules for payload return from LEO.
ATMOS Space Cargo is a space logistics company based in Lichtenau, Germany, that designs and manufactures reusable return capsules to bring payloads from low Earth orbit back to Earth. The organization provides end-to-end mission operations, including payload integration, in-orbit control, and controlled re-entry, primarily serving the microgravity research, biotechnology, and advanced materials sectors. Operating with more than 70 employees across offices in Germany and France, the enterprise has scheduled seven launches between 2026 and 2028. The company has raised €4 million in oversubscribed seed funding from lead investors such as High-Tech Gründerfonds, Amadeus APEX Technology Fund, Seraphim Space, and E2MC Ventures. Its technology, including the Phoenix return capsule, is utilized by commercial space entities and space agencies such as the European Space Agency. ATMOS Space Cargo was founded in 2021 by Sebastian Klaus.

ATMOS Space Cargo is a German space technology startup that designs and manufactures re-entry capsules, such as the PHOENIX series, to provide affordable, reliable, and eco-friendly cargo return services from orbit, primarily for life sciences research in microgravity.[1][5] It serves researchers and organizations conducting experiments like protein crystallization, stem cell growth, organoids, and monoclonal antibodies, solving the key challenge of high-cost, unreliable sample return after launches have become cheaper.[3][5] The company offers microgravity environments from hours to months, accommodating standard ISS mid-deck lockers with 100 kg payload capacity and power, and has demonstrated strong growth: seed funding in 2023, FAA approval in January 2025, successful PHOENIX 1 re-entry flight in April 2025 on SpaceX's Bandwagon-3, partnerships like with Space Cargo Unlimited for 2026 missions, and a May 2025 alliance with ARX Robotics for orbital depots.[1][2][4]
Founded in 2021 (formerly Klaus Space Transportation), ATMOS has quickly scaled with backing from investors including Hightech Gründerfonds, Amadeus APEX, Balnord, Seraphim, and the European Innovation Council, positioning it as Europe's first private re-entry pioneer with plans for monthly flights and US expansion.[2][5]
ATMOS Space Cargo was founded in 2021 in Lichtenau, Germany, by Sebastian Klaus (CEO), an aerospace engineer with over a decade as a military officer specializing in special missions and atmospheric re-entry systems.[1][2] Key team members include COO Marta Oliveira (Forbes 30 Under 30, with experience at NASA, ESA, and CNES as a launcher safety engineer for Ariane 5), alongside Jeff and Christian, forming a team blending space expertise and rapid execution.[2]
The idea emerged from recognizing a gap in space logistics: while launches are cheaper, returning payloads—especially for biomedical research dominant on the ISS—remains expensive and unreliable.[3] After seed funding in summer 2023, the team analyzed ISS data, targeting life sciences like protein crystallization and tissue printing, and rapidly built PHOENIX 1 as a minimum viable product.[3] Pivotal moments include FAA payload approval in January 2025 (first for a private European entity), the April 2025 Bandwagon-3 launch and re-entry (10x payload efficiency improvement), and subsequent partnerships accelerating commercialization.[2][1]
ATMOS rides the post-ISS orbital logistics boom, where cheap launches (e.g., SpaceX rideshares) enable microgravity manufacturing/research, but return bottlenecks limit scalability for life sciences, biotech, and emerging in-space factories.[3][4] Timing is ideal amid ISS decommissioning in 2030s and Europe's push for sovereign space access, countering US dominance (e.g., NASA/DoD downmass).[2][4]
Market forces favor it: biomedical demand (e.g., cancer/aging research), defense needs (ARX alliance for rapid-response orbital depots), and scaling to 25-ton payloads for large factories.[1][4] ATMOS influences the ecosystem by pioneering European re-entry, fostering partnerships (ESA, SCU), and validating high-cadence models, potentially democratizing space R&D and boosting Europe's space economy.[5][3]
ATMOS is poised to lead Europe's space return logistics with Phoenix 2 in 2026, multiple SCU missions, monthly flights, and US/DoD expansion, scaling from life sciences to defense and manufacturing.[4][1] Trends like routine microgravity production, sovereign orbital infrastructure, and inflatable tech maturation will propel it, evolving from niche returns to enabling orbital economies with 25-ton capacity.[3][4] As the first private European re-entry success, its momentum—fueled by elite founders and investors—positions it to bridge Earth-space logistics, transforming life sciences research from experimental to industrial-scale.[2][5]
