MIPRONS

MIPRONS envisions using water as a gateway to a new space revolution, emphasizing both performance and sustainability. To achieve this, we are developing the smallest and most powerful propulsion system based on water electrolysis. This innovative solution, protected by five patents covering its overall architecture and key components, offers unparalleled advantages in terms of performance, safety, environmental impact, component procurement, geopolitical technological independence, and regulatory simplification.

MIPRONS has already received global interest from leading stakeholders in the space industry. We have signed a "co-development/pre-commercial agreement" with Thales Alenia Space, and an "industrial agreement" with Zoppas Industries (a global leader in satellite thermal management) is under negotiation. In addition, MIPRONS received endorsement from the European Space Agency (ESA) as one of Europe's most promising space companies. 

Why is MIPRONS considered a game-changer?

Its propulsion technology addresses the primary issues faced by current satellites:

  • Slow maneuvering capabilities, which drastically limit their operativity and reduce profitability.
  • The need for procuring components and hazardous/toxic propellants, which must comply with strict export regulations and certifications, increaseding lead times and costs.
  • Operational risks, with 42% of smallsat missions experiencing failures due to propellant leakage, electrical issues, and electromagnetic interference (EMI). Additionally, satellites face a growing risk of collision, exacerbated by slow maneuvering.
  • Limitations in fuel pre-positioning in orbit.
  • Inability to reuse fuel for other space applications.

First and foremost, MIPRONS tackles these problems using water, a readily available resource from in-situ sources. Water is inexpensive, safe, environmentally friendly, and free from regulatory restrictions, providing a significant boost to human space exploration.

Additionally, MIPRONS features patented components specifically designed for miniaturization while delivering high performance in terms of thrust and specific impulse. The system carries water, which is split into hydrogen and oxygen by an innovative electrolyzer directly in orbit. The hydrogen and oxygen are then fed into a swirling combustion chamber that generates high thrust. For example, a combustion chamber just 10-15 mm in size can produce several Newtons of thrust. The overall propulsion system has a volume of approximately 0.7U and a weight of 1.4 kg. This compact design allows MIPRONS to be installed in satellites of any size (nanosats as well as largesats), making versatility one of its key advantages, enabling "plug-and-play" configurations.

In fact, it is not by chance that MIPRONS is already working on 150kg and 1ton satellites with Thales-Italia.

As of today, the MIPRONS water-electrolysis propulsion system has reached TRL=5/6 (Technology Readiness Level). The working prototype is expected to be finalized by the second half of 2026 with an IOD (In Orbit Demonstrator) according to the first flying availability.

The Company has operative headquarters in Colleferro (Rome), equipped with High Performing Computing, Hydrogen-Oxygen test bench and a vacuum chamber for tests at space conditions.
