Rule 42 (Propulsion)

Rule 42 (Propulsion) is a regulation that sets safety standards for spaceships and their propulsion systems, including engines and fuel handling. It ensures that all propulsion equipment operates reliably and safely, minimizing risks like explosions, fires, or loss of control. The rule covers design, testing, maintenance, and operation procedures, emphasizing the importance of thorough safety measures throughout the lifespan of propulsion systems. Its goal is to protect crew, the environment, and property by establishing clear guidelines for the safe development and use of spacecraft engines and related propulsion technology.
