SpaceX’s Falcon 9 rocket recently experienced a rare inflight failure during the “Starlink Group 9-3” mission, leading to the grounding of the workhorse vehicle for investigation. The incident took place after the rocket’s lower first stage performed as expected, but the upper second stage failed to reignite its engine, resulting in its destruction. This unexpected turn of events left CEO Elon Musk confirming the failure and citing an “engine RUD,” or “rapid unscheduled disassembly,” caused by reasons that are currently unknown.
The Federal Aviation Administration (FAA) has stepped in to oversee SpaceX’s investigation process and will need to approve the final report and any corrective actions taken by the company. This level of involvement from the federal regulator highlights the seriousness of the incident and the need for a thorough examination before the Falcon 9 can resume its launch operations. The delay caused by the investigation is expected to impact upcoming missions, including the private Polaris Dawn and NASA’s Crew-9.
Despite the failure of the second stage engine, SpaceX managed to deploy 20 Starlink satellites during the mission. However, the lower-than-intended orbit caused by the engine failure meant that the satellites could not be fully recovered. The company made an attempt to contact 10 of the satellites in order to utilize their onboard thrusters to climb higher in orbit, but the high-drag environment of the lower orbit made it impossible to save the satellites. As a result, the 20 satellites are expected to re-enter the Earth’s atmosphere and burn up, with SpaceX ensuring that they pose no threat to other satellites or public safety.
The incident marks a significant break in the otherwise impeccable track record of SpaceX’s Falcon 9 rocket, which had previously achieved over 300 consecutive successful orbital launches. The last inflight failure occurred in June 2015 during the NASA cargo mission CRS-7, making this recent incident a rare occurrence for the company. Despite this setback, Falcon 9 has completed a total of 354 missions to orbit, with the majority resulting in successful landings and the reuse of rocket boosters over 280 times.
SpaceX’s Falcon 9 rocket incident serves as a stark reminder of the inherently risky nature of space exploration and the need for constant vigilance and improvement in the industry. The investigation into the failure will be crucial in identifying the root cause of the incident and implementing necessary corrective measures to prevent similar occurrences in the future. As SpaceX continues to push the boundaries of space technology, it is essential that lessons are learned from such setbacks to ensure the safety and reliability of future missions.
