Core Insights - SpaceX's Starship Super Heavy rocket experienced its eighth test flight failure due to engine malfunctions leading to a chain reaction that resulted in the rocket's self-destruction in mid-air [1][3] - The Federal Aviation Administration (FAA) has approved the investigation report and subsequent flight tests, with the ninth test flight scheduled for May 27 [1][4] Group 1: Test Flight Failures - The Starship's previous test flights have garnered significant attention, but both of its attempts in 2023 ended in failure [1] - The seventh test flight on January 17 saw the Starship spacecraft lose control during re-entry, leading to self-destruction due to high vibration intensity causing fuel leakage and fire [1] - The eighth test flight on March 6 faced a similar fate, with the first stage successfully recovering but the spacecraft disintegrating mid-air [1][3] Group 2: Investigation Findings - The investigation report indicated that the failure during the eighth test was due to a hardware fault in the central engine, causing unintended mixing and ignition of propellants [3] - The report highlighted that the failure was not the same as the previous test, with a "flash" event occurring in the engine center leading to a shutdown of one engine and subsequent failures in adjacent engines [3] Group 3: Remedial Actions - SpaceX's corrective plan includes increasing preload at critical connections, optimizing propellant discharge systems, and introducing a new generation of engines to enhance reliability [3] - The first stage of the Starship successfully recovered but experienced issues with two engines failing during the retrofire phase and one during landing, attributed to localized overheating [3] Group 4: Upcoming Test Flight - The ninth test flight will take place at Boca Chica, Texas, with plans to test multiple objectives, including deploying eight prototype Starlink satellites [4] - For this mission, SpaceX will not attempt the previously validated pinpoint landing and recovery of the first stage, opting instead for a soft landing in the Gulf of Mexico [4]
