Catalyx Space is building the world's best reentry systems. Our reusable ReX vehicles return payloads from orbit at unprecedented scale, up to 12 tons and 60m³ of cargo, while operating the full mission lifecycle from launch to recovery. Our core innovation is a tension-based deployable heat shield that combines the scalability of an inflatable system with the robustness of a rigid structure. Built from commercial off-the-shelf components, it enables the world's widest heat shields, the largest payload return volumes, and a scalable pathway for returning everything from commercial cargo to future space nuclear assets.
