WaterCube+

WaterCube+ is our newly developed innovative propulsion system that uses demineralised water as propellant: safe, sustainable, and cost-effective. Designed for missions where simplicity, quick delivery and flexibility matter, WaterCube+ enables orbit maintenance, collision avoidance, formation flying, active de-orbiting and proximity operations, while also streamlining ground integration and testing activities.

This upgraded version of WaterCube features an integrated chemical and resistojet propulsion system to leverage the best from both technologies while using water as propellant, and it will be available for commercial missions from late 2027.

Compact, scalable, and easy to integrate, WaterCube+ is ideal for CubeSats and microsatellites up to 500 kg. Its plug-and-play architecture cuts integration time and cost, while modular design adapts to mission-specific thrust and impulse needs. With no toxic propellants and a fully European supply chain, WaterCube+ brings performance and sustainability together: for safer, smarter, and greener access to space.
