At the time, the FAA also noted that it would expand the size of the hazard zones — or keep-out areas for aircraft — that will be locked down during the next Starship flight. The agency said it made the change in response to the two prior mishaps, Flight 7 in January and Flight 8 in March, which signaled “a greater probability of failure” in the FAA’s calculations. SpaceX for the first time also intends to attempt to reuse a Super Heavy rocket booster on Flight 9. Super Heavy is the largest piece of the Starship launch system and consists of a 232-foot (71-meter) steel cylinder, fuel tanks, and all 33 rocket engines that give the initial burst of thrust at liftoff. SpaceX has so far safely recovered three Super Heavy boosters after launch with the goal of refurbishing and reusing the rocket parts to drive down costs. Expanding hazard areas The FAA said it would expand the size of the Starship hazard area — which is intended to keep aircraft and other vehicles out of the launch system’s flight path — from 885 nautical miles (1,018 miles) mapped out in earlier documents to 1,600 nautical miles (1,841 miles) for the Flight 9 test launch. The expanded keep-out zone is expected to affect as many as 175 flights, with an expected average delay time of 40 minutes, according to the FAA. The agency estimates such delays cost travelers about $50 per hour and cost passenger airlines as much as $100.80 per minute, or $6,048.00 per hour per delayed flight. “To minimize disruption,” the document states, “the launch window has been scheduled outside peak transit periods.” SpaceX has not yet publicly announced a target launch time for Flight 9. Falling debris risks The FAA also maps out debris response areas where it believes pieces of the vehicle might land if it explodes midflight. SpaceX said after both the Flight 7 and Flight 8 mishaps that debris mostly stayed within such areas. But in January, pieces of the failed Starship vehicle from Flight 7 notably wound up strewn across the islands of Turks and Caicos. There was also one report of property damage: A piece of debris struck a car on the island of South Caicos, the FAA confirmed at the time. Turks and Caicos resident Morgan May Luker took this photo of SpaceX Starship debris on the north end of the island of Providenciales, an area called Wheeland, on January 19. Morgan May Luker
