Producer The Federal Aviation Administration has grounded all SpaceX Falcon 9 flights after a fiery mishap during Wednesday morning's Starlink launch."The incident involved the failure of the Falcon 9 booster rocket while landing on a droneship at sea. No public injuries or public property damage have been reported. The FAA is requiring an investigation," an FAA spokesman told WESH 2.Just before 4 a.m., SpaceX launched a Falcon 9 rocket carrying 21 Starlink satellites from Cape Canaveral to low-Earth orbit. The launch went according to plan, but the first-stage booster's return did not. Following stage separation, the booster landed on a drone ship in the Atlantic Ocean, then tipped over as it became engulfed in flames. SpaceX said it was still assessing the booster's flight data and status.Another Starlink launch was supposed to take off from California Wednesday, but the company scrubbed that attempt to "give the team time to review booster landing data from the previous launch."Though the booster's landing went awry, SpaceX did confirm that all the satellites had been deployed successfully.Polaris Dawn launch The FAA's investigation comes right as the company was expected to launch the historic Polaris Dawn mission, though that launch was indefinitely postponed before the Starlink launch mishap.The Polaris Dawn mission, which is set to carry four civilian astronauts to extreme orbital altitudes, was expected to launch Monday, then Tuesday and then Wednesday. SpaceX has cited a helium leak and unfavorable weather conditions as reasons for some of the delays.>> Polaris Dawn mission: Everything to know about SpaceX's crewed flight launching from Central FloridaAfter Wednesday's launch and Thursday's backup launches were scrubbed, the company did not announce another targeted launch date. According to SpaceX, it is waiting to find a time when weather conditions are favorable for both take-off and splash-down.The SpaceX Crew Dragon capsule is set to launch atop a Falcon 9 rocket, which is now grounded.SpaceX's second FAA investigation this yearThis is not the first time SpaceX has been investigated by the FAA this year. In July, all Falcon 9 rockets were grounded after a different mishap. After launching a Starlink mission from Vandenberg Space Force Base in California, SpaceX said its second-stage engine did not complete its second burn, leading to the satellites being deployed to a lower orbit than intended. The company tried to use thrusters to raise the satellites, but all 20 of them re-entered the Earth's atmosphere. SpaceX said all satellites fully demised upon reentry, but the FAA launched an investigation to further enhance public safety.That investigation was completed just a few days later, and a report gave more details about what happened during the flight and explained how SpaceX would correct these issues."Safety and reliability are at the core of SpaceX's operations," the company said at the end of that investigation. The Falcon 9 rockets were grounded for about two weeks.Return to flightAt this time, it is unclear how long this investigation will take or how it will impact SpaceX's future launches."A return to flight of the Falcon 9 booster rocket is based on the FAA determining that any system, process, or procedure related to the anomaly does not affect public safety. In addition, SpaceX may need to request and receive approval from the FAA to modify its license that incorporates any corrective actions and meet all other licensing requirements," the FAA said in a statement to WESH 2.
