The agency is expanding the size of hazard areas in the United States and in other countries based on an updated "flight safety analysis" from SpaceX and because SpaceX will reuse a previously flown first-stage booster—called Super Heavy—for the first time.

The size of FAA-mandated airspace closures can expand or shrink based on the reliability of the launch vehicle. The failures of Starship earlier this year raised the probability of vehicle failure in the flight-safety analysis for Starship Flight 9, according to the FAA.

If SpaceX can reel off a series of successful Starship flights, the hazard areas will likely shrink in size.
