Following the May 29 explosive failure of Starship SN4 Prototype during Static Fire test, SpaceX workers have been quickly making repairs to its Boca Chica, Texas Launch facility. Starship SN5 is expected to roll to the Launch site in coming days in preparation for testing to begin on June 10. Anomaly total existing test stand used to hold down vehicle during testing milestones. On June 3, replacement Launch stand was installed at Launch site. SpaceX had already been working on a new Launch stand before the May 29 accident-factor that accelerates the recovery process. The new stand appears to be similar in design to the original Starship Launch mount. In coming days, teams will continue to repair Ground Support Equipment at the Launch site. There was significant damage to GSE infrastructure due to the anomaly, but SpaceX will have the GSE repaired in time for testing to resume on June 10, per the latest notice of road closures. While the Starship SN4 anomaly was dramatic, required corrective action is not expected to be too complicate. Early indications were that issues with umbilical connections to vehicle leak significant quantities of propellant near the base of the vehicle. SpaceX CEO Elon Musk later confirmed to Reuters reporter Joey Roulette that the problem was related to the quick disconnect system. It is understood that one of the test objectives of May 29 Static Fire was to test disconnecting umbilicals ahead of the planned 150-meter test flight schedule for the following week. Umbilicals must be able to quickly detach when the Launch Vehicle leaves the pad. During testing of quick disconnects, system malfunction-spilling large amounts of propellant. This could be seen during NASASpaceflights live stream of test. Propellant eventually ignite, leading to a large explosion. It is not entirely clear what the ignition source was, but still frame from the NASASpaceflight broadcast shows that the ignition occurred near the base of the vehicle. Notably, structural integrity of Starship is not believed to be the cause of the accident. SpaceX has had issues with prototypes collapsing under high pressure in the past. All of the previous full-scale prototypes failed cryogenic pressurization testing. Including the May 29 test, SpaceX completed five Static fires with Starship SN4. No previous Starship had even gotten far enough to have engine instal. Raptor engines performed well throughout testing, and the vehicles ' primary structure held strong. If structural issues had been the cause of the recent anomaly, flight-worthiness of SpaceXs upcoming prototypes might have been invalidate. Starship SN5 is scheduled to roll to Launch pad on Monday, Starship SN6 is undergoing final assembly, and Starship SN7 bulkhead has already been spot. It is unlikely that quick disconnect issue will require significant changes to these vehicles-avoiding prolonged setback for SpaceX.
