Which aspect must be checked before launching a high-power rocket?

Checking the integrity of the rocket structure and compliance with safety regulations is crucial before launching a high-power rocket. This ensures that the rocket is constructed properly, made of materials that can withstand the forces of launch and flight, and that any potential failure points (such as joints or seams) are secure. Compliance with safety regulations is equally important as these guidelines have been established to protect both the rocket and its surroundings, including people, property, and the environment.

Ensuring structural integrity helps prevent accidents that could arise from a rocket failing during flight, which can have catastrophic consequences. Safety regulations often include specifications regarding materials, construction standards, and required safety equipment—so verifying that the rocket meets these guidelines is essential for any launch.
