Atmos Space Cargo

Atmos Space Cargo, founded in 2022 and headquartered in Stuttgart, Germany, is developing Phoenix — a commercial atmospheric reentry vehicle for returning manufactured products, biological specimens, and research samples from the International Space Station and commercial space stations to Earth, using an inflatable aeroshell (HIAD — Hypersonic Inflatable Aerodynamic Decelerator) heat shield technology that provides high-volume return capacity at lower mass penalty than traditional rigid aeroshells.

The Phoenix spacecraft is designed to carry up to 100 kg of payload in a pressurized cargo bay, with temperature-controlled environments for sensitive biological samples and precision-manufactured components. The inflatable aeroshell deploys before atmospheric entry, creating a large surface area that generates high drag for deceleration without the structural mass of a conventional ablative shield — potentially enabling higher mass fraction of payload per unit of total vehicle mass compared to capsule-style reentry vehicles like Northrop Grumman's Cygnus or SpaceX's Dragon.

Atmos Space Cargo's April 2025 test flight successfully demonstrated Phoenix's inflatable heat shield deployment and atmospheric reentry survivability — a critical technical milestone validating the HIAD concept's performance in the actual entry environment rather than Earth atmosphere simulations. Following this success, the company is targeting commercial reentry service operations beginning in 2026, initially focusing on pharmaceutical and biotechnology customers conducting microgravity manufacturing research who need to return protein crystals, cell cultures, and drug compounds produced in the unique microgravity environment of the ISS.

The company is part of the growing European in-space economy infrastructure sector, funded by European deep tech investors and supported by Germany's strong pharmaceutical and precision manufacturing industries that are primary customers for microgravity production services. Atmos competes with Varda Space Industries (US), Space Forge (UK), and Redwire Space in the commercial space manufacturing return logistics market.
