High-performance water-based thruster systems designed for safe and fast launch integration with maximum delta-V for CubeSat constellations. Consuming just 20W they deliver Isp up to 172s and 20mN thrust in a modular 0U-2U form factor for rapid orbital maneuvering.
TunaCan: Space-Efficient Propulsion for CubeSats
Maximize your satellite's potential with the TunaCan module, our premier, flight-proven propulsion for CubeSats designed to fit within the CubeSat deployer's auxiliary volume. This unique design allows you to add high-performance maneuvering capabilities to your mission without sacrificing a single centimeter of internal payload space. Powered by safe, non-toxic water, the TunaCan delivers a reliable thrust of up to 20 mN and a competitive Isp, making it the ideal "bolt-on" solution for rapid orbit insertion or collision avoidance. Small in footprint but massive in utility, the TunaCan is the ultimate green-propellant upgrade for standard 3U, 6U, and 12U platforms.
Thruster One: Custom-Integrated Propulsion for CubeSats and Small Satellites
The Thruster One is our flagship flight-proven propulsion for CubeSats and Small Satellites, offering unparalleled integration flexibility for platforms from 6U to 16U and larger. Beyond the standard 2U size, our modular architecture allows us to design a custom fuel tank that contours to your satellite’s unique internal geometry, filling all available free space to maximise propellant volume. By utilising safe, non-toxic water, we provide a high thrust of 20 mN while ensuring optimal mass distribution and a stable center of gravity for your spacecraft. This "bespoke tank" approach transforms dormant internal gaps into active mission life, giving your SmallSat more delta-V without increasing its external footprint.
Key Missions
NASA Artemis II / NaraSpace K-RadCube
2026
Selected to perform critical orbit corrections for the 12U K-RadCube satellite. Our thruster raises the perigee from the upper atmosphere to a stable 180 km+ orbit to prevent premature re-entry.
SatRevolution "Above the Clouds"
2022
Successfully integrated aboard the SteamSat-1 (1.5U) to validate water-based resistojet technology for CubeSat manoeuvring and constellation management.
MBRSC "PHI-Demo" Mission
2023
Successfully commissioned as part of the Mohammed Bin Rashid Space Centre’s technology demonstration to prove the efficiency of steam-powered propulsion in a Sun-Synchronous Orbit (SSO).
Momentus Vigoride Technology Demonstration
(2021 - 2022)
Successfully integrated aboard the Vigoride Small Satellite to validate water-based resistojet technology for SmallSat manoeuvring and orbital management.
Multiple Undisclosed Commercial Missions
(2021 - 2025)
Several SteamJet propulsion modules are currently operational in orbit, providing station-keeping, orbital manoeuvring, and de-orbiting capabilities for private satellite constellations.
Industrial Applications:
the SteamJet Advantage
SteamJet’s propulsion for CubeSats is engineered to protect your most sensitive components. Here is how our unique technical features provide mission-critical benefits across every sector.
Earth Observation and Remote Sensing
The Feature: Clean Steam Exhaust and No Sedimentation.
The Benefit: Protect your high-value optical payloads. Unlike chemical thrusters that can leave oily residues or particulate matter, our water-based steam exhaust is ultra-clean. It ensures no “fogging” or sedimentation on lenses, mirrors, or sensitive infrared sensors.
Mission Advantage: Maintain crystal-clear imaging quality for the entire duration of the mission life.
Signals Intelligence and Telecommunications
The Feature: EMI/EMC Neutrality and No RF Interference.
The Benefit: Total electromagnetic silence. Traditional Hall thrusters generate plasma clouds that create significant radio frequency noise. SteamJet’s resistojet technology produces no RF interference, allowing your sensitive antennas and receivers to operate at maximum gain even during manoeuvres.
Mission Advantage: Zero signal degradation and simplified electromagnetic compatibility (EMC) testing.
IoT & M2M Narrowband Constellations
The Feature: Low-Pressure Water Propellant.
The Benefit: Drastically reduced launch integration costs. Because water is non-toxic and non-hazardous, IoT startups can bypass expensive “hazmat” fueling procedures and gain easier access to rideshare launches.
Mission Advantage: Affordable, scalable propulsion for mass-produced small satellite fleets.
Space Sustainability & De-orbiting
The Feature: High Volumetric Efficiency (Custom Fuel Tanks).
The Benefit: Guaranteed end-of-life disposal. By utilizing all free space inside the satellite for water storage, we provide the maximum possible delta-V for a controlled re-entry, ensuring compliance with international “Zero Debris” mandates.
Mission Advantage: Future-proof your mission against evolving space-traffic regulations.
Academic & Technology Demonstrators
The Feature: “Plug-and-Play” Architecture & Safe Propellant.
The Benefit: Simplified lab handling and safety approvals. Universities can integrate SteamJet propulsion for CubeSats in standard cleanrooms without the specialized SCAPE suits or high-pressure facilities required by Xenon or Hydrazine systems.
Mission Advantage: Reduces the complexity and timeline of student-led or experimental missions.
