Capsule Corporation is an Italian aerospace startup developing WaterCube, a sustainable and modular propulsion system for CubeSats and SmallSats, using demineralised water as propellant. Leveraging metal additive manufacturing and a proprietary heat-exchanger technology, WaterCube enables orbit control, collision avoidance, and deorbiting with up to 50% lower cost, shorter lead time and streamlined integration and testing compared to traditional systems.
Currently advancing toward its in-orbit demonstration in 2026 under ESA supervision, Capsule Corporation is seeking commercial partners, satellite manufacturers, and integrators interested in integrating WaterCube in future missions, as well as partnerships for production scaling and system customisation.
WaterCube: Safe, modular water-based propulsion for CubeSats/SmallSats, built with metal additive manufacturing. No pressurised or toxic propellant, up to 50% lower cost and integration time, 14-week lead time. TRL 7, IOD Q1 2027 under ESA supervision.
WaterCube+ brings higher performance to water propulsion: a dual-mode chemical hydrolitic and resistojet system for CubeSats/SmallSats, developed under an ESA contract we lead as prime. TRL 5, launch Q2 2028. Seeking early adopters to shape QM development
