The U.S. Federal Aviation Administration (FAA) has grounded SpaceX's Falcon 9 rockets following a fiery landing mishap on August 28, where the booster toppled over and caught fire upon returning to Earth. Despite the incident, the FAA has allowed SpaceX to resume flights provided that all other license requirements are met. This decision comes amid ongoing investigations into the anomaly that occurred during a Starlink mission. The grounding affects the upcoming Polaris Dawn mission, aimed at performing the first spacewalk by private astronauts, and could also impact NASA's Crew-9 mission scheduled for next month. SpaceX's Falcon 9 had previously been grounded in July for a different issue but was cleared to fly again after 15 days.
