SpaceX’s Falcon 9 rocket is grounded again after the vehicle’s second stage did not come down in the expected area of the ocean, following an otherwise successful mission that delivered a Dragon capsule and its crew to orbit. “We will resume launching once we better understand root cause,” the company said in a statement posted to X .

UPDATE: The Federal Aviation Administration is "requiring an investigation," meaning Falcon 9 flights have also been grounded until SpaceX receives regulatory clearance to resume launches. Original story: SpaceX has hit another snag with its Falcon 9 rocket, which is causing the company to delay further launches.
