SpaceX’s Falcon 9 rocket recently suffered an inflight failure during the “Starlink Group 9-3” mission, leading to the grounding of the vehicle for an investigation. This incident is a rare misfire for the workhorse rocket, which has been on a successful run for nearly a decade.
The rocket’s lower first stage performed as expected, but the upper second stage failed to reignite its engine as planned, resulting in a rapid unscheduled disassembly (RUD). SpaceX CEO Elon Musk confirmed that the failure was caused by an engine RUD due to reasons currently unknown. The company later revealed that the engine failure was triggered by a leak of liquid oxygen in the second stage.
FAA Involvement
The Federal Aviation Administration (FAA) has grounded the Falcon 9 rocket until SpaceX completes its investigation and the regulator approves the final report and any corrective actions. This means that upcoming launches, including crewed missions like the private Polaris Dawn and NASA’s Crew-9, may be delayed.
Despite the upper stage engine failure, SpaceX managed to deploy 20 Starlink satellites. However, the satellites were placed in a lower than intended orbit, making them unrecoverable. SpaceX attempted to use the satellites’ onboard thrusters to climb higher in orbit, but the high-drag environment in the lower orbit means that the satellites will eventually re-enter the Earth’s atmosphere and burn up.
Prior to this incident, SpaceX’s Falcon 9 rocket has maintained an impressive track record of success, with more than 300 consecutive successful orbital launches. The last inflight failure occurred in June 2015 during the NASA cargo mission CRS-7. Overall, the Falcon 9 rocket has completed 354 missions to orbit, with over 300 successful landings and the reuse of rocket boosters more than 280 times.
The recent grounding of SpaceX’s Falcon 9 rocket highlights the inherent risks of space exploration and the importance of thorough investigation and regulatory oversight. While this incident may affect the company’s launch schedule in the short term, SpaceX’s history of resilience and innovation suggests that it will overcome this setback and continue to push the boundaries of space technology.
