WaterCube is a sustainable water-based propulsion system for CubeSats and SmallSats, designed to deliver reliable in-space mobility with unmatched operational simplicity. Leveraging non-toxic propellant, additive manufacturing, and a modular architecture, WaterCube enables orbit raising, station keeping, collision avoidance, and deorbiting while reducing integration effort, testing complexity, and mission risk.
Unmatched lead time in the industry: 3 months from order.
Green, sustainable and safe choice.
Primary propulsion for CubeSat > 3U, primary or secondary propulsion for Smallsats.
off-the-shelf components and 3D printing allows serial production, modularity and short delivery time.
allows Cubesats and Smallsats to perform all the needed orbital maneuvers for a variety of missions.

Ensure responsible end-of-life disposal and regulatory compliance. WaterCube enables controlled deorbiting maneuvers, helping operators reduce space debris and contribute to a safer, more sustainable orbital environment.
Protect your mission from an increasingly congested space environment. WaterCube provides the maneuverability needed to perform timely collision avoidance maneuvers, reducing operational risk and safeguarding valuable spacecraft assets.
Keep your satellite exactly where it needs to be. WaterCube compensates for orbital perturbations and atmospheric drag, extending mission lifetime and ensuring optimal payload performance throughout the mission.
Enable precise coordination between multiple spacecraft. WaterCube supports accurate orbital adjustments and relative positioning, allowing constellations and distributed missions to operate as a synchronized system.
Achieve enhanced spacecraft agility and mission flexibility. WaterCube can support fine attitude adjustments, rendezvous, inspection, servicing, and proximity operations, enabling advanced mission concepts that require precise control and maneuverability in orbit.
Our product family -WaterCube, WaterCube+, and OrbitRev - is redefining in-space mobility through sustainable propulsion technologies and mission support services. Designed to streamline spacecraft deployment and operations, our solutions reduce integration barriers, accelerate time-to-orbit, and unlock greater operational flexibility for commercial, institutional, and defense missions alike.
