SpaceX launches are on hold after a booster rocket toppled over in flames while landing. The Federal Aviation Administration grounded the company’s Falcon 9 rockets and ordered an investigation following Wednesday’s accident off the Florida coast. It’s too early to know how much impact this will have on SpaceX’s two upcoming crew flights, one private and the other for NASA. The Falcon 9 rocket lifted off before dawn, and all 21 Starlink internet satellites made it to orbit. But the first-stage booster fell over in a fireball upon landing on an ocean platform.
