The newest in Europe facility for rocket propulsion testing under vacuum conditions was opened in 2023. It allows for conducting research on rocket engines and their components under conditions similar to those of space. Precise measurement of parameters such as thrust, pressure, and operating time is crucial for optimizing the durability and reliability of rocket propulsion (satellites), which is a fundamental requirement for ensuring safety and success of space missions.

Spacecraft propulsion test facility – research scope
