The U.S. Federal Aviation Administration (FAA) has made it clear that SpaceX is required to delve into the causes behind the booster's sub - par performance during last Friday's test flight before being permitted to launch the Starship rocket once more. Last Friday, despite the successful separation of the Starship booster from the spacecraft, it fell short in achieving the engine ignition that was crucial for preparing the booster for a splashdown landing. In the aerospace industry, when problems emerge during a spacecraft's flight, it is a standard practice for the FAA to demand that the relevant space company conduct a thorough accident investigation. This is to ensure the safety and reliability of future space missions, as space exploration involves high risks and complex technical operations. By investigating the root causes of the issues, companies can take corrective measures to prevent similar problems from occurring again.
