SteamJet's Water-Based Thruster Makes Waves in Artemis II Mission
SteamJet's eco-friendly thruster serves pivotal role in NASA's Artemis II mission with groundbreaking water-based propulsion.

In a remarkable leap for sustainable space exploration, UK’s SteamJet Space Systems has been selected to power the Korean CubeSat for NASA’s Artemis II mission with its innovative water-based propulsion technology. This cutting-edge Steam Thruster One, making use of low-pressure water, reduces the hazardous impacts of traditional propulsion systems and heralds a new era in satellite mobility.
A New Era in Propulsion Technology
Unlike conventional systems, SteamJet’s thruster utilizes water as its main propellant, delivering a durable and safe alternative. With a thrust capacity of 6mN at only 20W, it promises efficient orbital and collision adjustments for small satellites, broadening the horizons for space tech while championing green practices. According to The Engineer - Home, the water-based system not only mitigates harmful emissions but also offers a versatile solution adaptable to various mission needs.
Artemis II and Beyond
Set to be implemented in the Korean K-RadCube satellite, this thrust system will play a crucial role in navigating the daunting Van Allen radiation fields. Artemis II’s payload will place the CubeSat in an elliptical orbit before the SteamJet unit performs a record-bending 12-hour burn to maintain a secure trajectory, ensuring a successful mission.
Pioneer in Orbit
Marco Pavan, SteamJet’s CEO, emphasized, “Participating in Artemis II is a tremendous accolade for us. It exemplifies our commitment to sustainable and high-performance space exploration.” This mission stands as a testament to the blend of innovation and practicality championed by the company, having already achieved flight heritage in 2023.
The integration of SteamJet’s propulsion in a NASA-affiliated mission marks a pivotal moment not just for the company, but for the aerospace industry as a whole. It signals a shift towards more eco-friendly yet powerful methodologies in satellite propulsion systems.
The Broader Impact
This achievement redefines what is possible for CubeSats and small satellites. No longer bound by the limitations of traditional fuels, they can now explore with increased autonomy and safety. It’s a development that paints a promising future for sustainable and versatile satellite propulsion methodologies.
Looking Forward
With detailed technical specifications and extensive test data available for enthusiasts and professionals alike on the company’s website, SteamJet continues to set the standard in contemporary space advancements. This milestone is more than just a technical achievement; it’s the dawn of a sustainable journey for space exploration that aligns technology with environmental consciousness. As stated in The Engineer - Home, the impact of such innovations extends far beyond the Artemis II mission, shaping the very future of space tech.
