SpaceX has pinpointed a liquid oxygen leak as the cause of a Falcon 9 malfunction, clearing the path to restart Starlink satellite launches.
SpaceX is preparing to resume its Starlink satellite launches following the identification of a malfunction in a Falcon 9 rocket that occurred on July 11. The company has determined that a liquid oxygen leak was responsible for the failure that prevented 20 Starlink satellites from reaching their intended orbit.
According to SpaceX’s report, the issue originated from a crack in a “sense line” connected to the pressure sensor in the Falcon 9’s upper-stage engine. This sensing line, crucial for measuring and regulating engine components’ voltage, suffered fatigue and damage due to high engine vibration and a loose clamp. The leak led to excessive cooling of engine components, causing a hard start instead of a controlled burn during the second engine burn. This malfunction resulted in the upper stage losing attitude control and deploying the satellites into a lower-than-expected elliptical orbit, where they eventually burned up upon re-entry.
The Falcon 9 rocket, which has successfully completed 364 missions, experienced this rare glitch. SpaceX has addressed the issue by removing the faulty sensor and conducting a thorough review and replacement of similar components across its active booster fleet. The company has also implemented design changes and conducted tests at its Texas development facility with oversight from the Federal Aviation Administration (FAA).
The FAA, which is still investigating the incident, has cleared SpaceX to resume launches, stating that the malfunction does not pose a threat to public safety. This clearance allows SpaceX to continue with its planned Starlink missions, including the launch of a new batch of 23 satellites scheduled for July 27, weather permitting.
The resumption of launches is significant for SpaceX, as it continues to deploy satellites for its cellular Starlink system, which is set to partner with T-Mobile this fall.
