Summary

This episode of ‘Le Journal de la STARBASE’ provides a comprehensive update on recent activities at SpaceX’s Starbase facility in Texas. The host, Quentin, covers the static fire test of Booster 15, the assembly progress of Ship 35, and the movement of Ship 34 for its own testing. A significant portion of the video is dedicated to answering a subscriber’s question about the structural integrity of the engine attachment points, particularly in light of the Ship 33 anomaly during Flight 7. The explanation delves into the engineering challenges of mounting multiple engines, comparing the Starship’s design with historical rockets like the Saturn V and the Soviet N1. The host explains how the Starship’s stainless steel structure, combined with tank pressurization, distributes thrust loads, and discusses the potential for future design changes such as increased diameter or pressure. The video concludes with the assessment that the failure of Ship 33 was likely not due to the engine thrust exceeding structural limits, but rather to another cause, possibly related to internal fire or other systems.
