MIPRONS

MIPRONS S.r.l. is an Italian space propulsion startup founded in 2019, specializing in miniaturized water electrolysis propulsion systems for satellites ranging from 10 kg to 700 kg. The company's patented technology splits water (H₂O) into hydrogen and oxygen through electrolysis in orbit, then combusts the gases in a micro-combustion chamber to generate high-performance chemical propulsion without the need for hazardous propellants such as hydrazine. MIPRONS's flagship propulsion system, ALEXIUS, is a compact 1.4 kg thruster delivering over 2.5 N of thrust and a specific impulse greater than 320 seconds — performance exceeding both conventional electric propulsion and traditional monopropellant systems. MIPRONS signed a co-development agreement with Thales Alenia Space Italia to develop water-powered micro thrusters for Thales Alenia Space's satellites, and the company was recognized as a finalist at the ESA BIC and BOLD Awards. MIPRONS participates in the ESA Commercialisation Gateway program.
