Ice

Electrolysis

The only propulsion system combining water electrolysis and hydrogen-oxygen catalytic combustion within a MEMS manufactured thruster. This leads to mass, volume and cost reductions compared to the current state-of-the-art.

Aquajet

ECR

Our cathodeless, ambipolar thruster for SmallSats is capable of operating on multiple propellants, including xenon, krypton, NH3, CO2 and water. It is based on Electron Cyclotron Resonance (ECR) at 2.45 GHz and a magnetic nozzle, which allows high performance, and uses a robust, simple design suited to low-cost high-volume manufacture.

Aquamet

Microwave electrothermal

Microwave Electrothermal thrusters (METs) create a free-floating plasma discharge in a cylindrical cavity resonator, efficiently heating a wide range of propellants while providing high thrust to power ratio. Our water-fuelled AQUAMET also features high specific impulse, from a simple, robust thruster at low cost.

URA means water in the Basque language, the oldest living language in Europe and, perhaps, the seed of all articulate language. At URA we will transform not communication, but in-space transport by providing green, low-cost and high-performance propulsion systems. Water is an enduring propellant choice: it is essential to our species, and will follow humans wherever we may explore.

At URA Thrusters, we provide in-space propulsion solutions for all type of spacecraft and mission needs, disrupting the status-quo of current propulsion systems by using the ultimate green propellant: URA [water].
