ECSS-E-ST-50 is a European space standard that provides a framework for the design, analysis, testing, and verification of propulsion and auxiliary systems for space vehicles. It defines the requirements for the development of propulsion systems and design and testing requirements for rocket engines, thrusters, fuel systems, and auxiliary systems, such as attitude control and reaction wheels to ensure safe, reliable, and effective operation. 

One of the key aspects of ECSS-E-ST-50 is the emphasis on safety and reliability. The standard provides specific requirements for the design and testing of propulsion systems to ensure they are safe and reliable. This includes requirements for the design and testing of the individual components of propulsion systems, such as rocket engines and propellant tanks, as well as the integration of these components into complete propulsion systems. The standard also covers the design and development of auxiliary systems, which are critical to the proper operation of propulsion systems. This includes requirements for the design and testing of power generation and distribution systems, thermal control systems, and avionics systems.

In addition to the design and development processes, ECSS-E-ST-50 also covers the testing and verification processes for propulsion and auxiliary systems. This includes the development of test plans and procedures, as well as the documentation of the test results. It also covers the environmental testing requirements, such as vibration and thermal cycling, to ensure that the propulsion and auxiliary systems can withstand the harsh conditions of space. Overall, ECSS-E-ST-50 provides a comprehensive framework for propulsion and auxiliary systems for space projects. By following this standard, space organizations can ensure that their propulsion and auxiliary systems are designed, analyzed, tested, and verified to the highest standards of performance, reliability, and safety, resulting in reliable and safe space missions.
