Thales Alenia Space and MIPRONS to develop a water-fueled space propulsion system » PACA’s Economic and Political Newsletter

A new innovative initiative for greener and sustainable use of space.

Thales Alenia Space, a joint venture between Thales (67%) and Leonardo (33%), has signed an agreement with Italian start-up MIPRONS to develop a highly innovative propulsion system for satellites using water as fuel! Based on MIPRONS proprietary technology, for which Italian patents are in the process of being filed in 49 other countries, this miniature thruster with high thrust will use a propellant that is ecological and economical to say the least: water! An electrolysis process breaks down the water into hydrogen and oxygen, which are then fed into the combustion chamber. With water as the only propellant, this system would make it possible to perform maneuvers such as positioning, deorbiting satellites or collision avoidance. Both compact and scalable, this system will be compatible with satellites of all sizes from small to large. The production of its components by 3D printing is another innovative factor in the MIPRONS concept. Designed specifically for the Thales Alenia space satellite, this high performance and thrust thruster will benefit from extremely low weight and size. Thales Alenia Space will oversee the development of this thruster with the aim of achieving a reliable and high-performance solution for small and medium-sized satellites. Italy’s Thales Alenia Space Engineering will support environmental testing of the model.

“We are delighted to team up with MIPRONS, whose reputation is growing internationally. Because our collaboration can change the model of space missions,” said Massimo Claudio Comparini, Chairman and CEO of Thales Alenia Space, Italy. “This agreement confirms Thales Alenia Space’s strategy to play a leading role in new space initiatives, creating synergies with start-ups that are catalysts within the entire space ecosystem. We are always ready to take on new challenges that underline the growing strategic importance of the space sector. “I am extremely proud of the agreement sealed with Thales Alenia Space”, announced Angelo Minotti, President and Founder of MIPRONS. “It is a huge opportunity to earn the trust of one of the largest aerospace companies in the world. Our project, though still in its infancy, has the potential to be a game-changer in the space sector and we will do everything to launch this system as soon as possible. »


The MIPRONS company was founded by Angelo Minotti with the aim of shortening the time to position satellites and reacting more quickly to collision risks.


Combining more than forty years of experience and a unique diversity of expertise, talent and culture, Thales Alenia Space architects design and deliver innovative solutions for telecommunications, navigation, Earth observation and environmental management, exploration, science and orbital infrastructure. Institutions, governments and businesses rely on Thales Alenia Space to design, build and deliver satellite systems: to geo-locate and connect people and objects anywhere on Earth; Observe our planet; Optimize the use of Earth’s resources and our solar system’s resources. Thales Alenia Space is sure that space brings a new dimension for humanity to build a better and sustainable life on Earth. The joint company between Thales (67%) and Leonardo (33%), Thales Alenia Space also forms the Space Alliance with Telespazio to offer a full range of solutions including services.
