In a groundbreaking development, a team of researchers at Imperial College London has unveiled a game-changing invention that could reshape the landscape of space propulsion. The ICE-Cube Thruster, a miniature rocket engine, not only runs on water but can also be held on your fingertip. This innovation has the potential to redefine the way we maneuver small satellites in the vast cosmos.

At the core of this revolutionary thruster lies a remarkable process known as electrolysis. By using a mere 20-watt electric current, an #electrolyzer splits water into hydrogen and oxygen gases. These gases, in turn, become the propellant for the thruster, eliminating the need for cumbersome storage tanks, a longstanding hurdle in miniaturizing propulsion systems.
The advent of the ICE-Cube Thruster couldn’t be timelier, as the small satellite market is rapidly expanding. These nanosatellites, weighing less than 10 kg, come with strict constraints on size, weight, power, and propellant. Conventional propulsion systems have struggled to fit within these confines, but the ICE-Cube Thruster seamlessly meets these demands.
According to data, the annual deployment of spacecraft is expected to triple from 2016 numbers. Most notably, #nanosatellites, which accounted for roughly 90% of spacecraft launched in 2017, require compact size, low power consumption, and eco-friendly propellants. The ICE-Cube Thruster not only fulfills these requirements but offers several other advantages.
First, it utilizes water as a propellant, which is not only non-toxic but also readily available. Second, its performance is unparalleled, thanks to hydrogen and oxygen’s efficiency as chemical propellants. Third, it consumes only a fraction of the power needed by comparable electric propulsion devices, well within the capability of nano-satellites. Finally, its micro-electronics-based manufacturing process enables precision, scalability, and cost-effectiveness.
What truly sets the ICE-Cube Thruster apart is its manufacturing process. It leverages micro-electrical mechanical systems (#MEMS), a technique commonly used in the microelectronics sector. This groundbreaking approach allows for the assembly of thruster components with sub-micrometer precision, paving the way for scalable, cost-efficient production.
The development of the ICE-Cube Thruster took place under ESA’s General Support Technology Program (GSTP), which seeks to de-risk new technologies for space applications. During tests at Imperial College London, the thruster achieved a remarkable 1.25 millinewtons of thrust at a specific impulse of 185 seconds on a sustained basis.
While this thrust may seem minuscule compared to the iconic Space Shuttle’s engines, its size and efficiency have the potential to transform the CubeSat industry. The experimental data collected will guide the creation of a flight-representative model of the propulsion system, including the electrolyzer, led by URA Thrusters in collaboration with Imperial College London.
The #ICECubeThruster is a miniature version of the #ICE200Thruster, a higher-thrust (1N) variant developed at #ImperialCollegeLondon. Both thrusters rely on the same principle of #waterelectrolysis and #iridiumcatalysis but differ in combustion chamber and nozzle size.
Notably, the ICE-200 Thruster has been chosen by ESA for the #LunarPathfinder mission, set to showcase lunar communication services in 2024. This thruster will play a pivotal role in providing attitude control and orbit maintenance for the Lunar Pathfinder spacecraft.
Both the ICE-Cube and ICE-200 thrusters are exemplars of how water can serve as a green and efficient propellant for space missions. Researchers anticipate that this technology will open up new possibilities and capabilities for small satellites in the future.
