SpaceX Completes Investigation into Reason for Engine Failure throughout the launch of Falcon 9 on July 11The corporate has filed an “accident report” with the Federal Aviation Administration (FAA) and is ready to return the Falcon 9 rocket to flight tomorrow.
The corporate’s investigation crew, working with the FAA, was capable of decide that the July 11 failure was attributable to a liquid oxygen leak that occurred throughout the preliminary burn of the Falcon 9’s second-stage engine. It stated the leak was attributable to a crack in a stress sensor line that’s a part of the rocket’s oxygen system. The clamp that usually restrains the sensor line weakened, exposing it to extreme engine vibrations, which ultimately induced it to fatigue and crack.
A liquid oxygen leak within the Falcon 9 rocket’s higher stage resulted in “extreme cooling of engine parts, primarily these related to supplying ignition fluid to the engine,” in keeping with assertion on the SpaceX web siteAs an alternative of a second managed burn, the engine skilled what SpaceX describes as a “exhausting begin,” which broken it and induced the higher stage to lose altitude management.
The Falcon 9’s first stage carried out as anticipated throughout its July 11 launch and landed safely for reuse, however an incident with the second stage resulted within the Starlink satellites being launched by the Falcon 9 being pushed right into a decrease orbit, the place “extraordinarily sturdy drag” induced all 20 of them to reenter Earth’s ambiance and hopefully dissipate.
To get the Falcon 9 again into flight as quickly as potential, SpaceX engineers will merely take away a sensor line and a sensor that failed on the second-stage engine. “The sensor shouldn’t be utilized by the flight security system and may be lined by different sensors already on the engine.” The corporate additionally inspected, cleaned, and changed some sensor traces and clamps on its “lively booster fleet.” The adjustments have already been examined by SpaceX at its facility in McGregor, Texas, below FAA oversight.
Now that the investigation is full, the Falcon 9 rocket is now not on the bottom and may return to service. firm web site SpaceX has scheduled its subsequent Falcon 9 launch with 23 Starlink satellites from NASA’s Kennedy Area Heart for July 27 at 12:21 p.m. ET, with extra launch alternatives out there later that day and July 28.
