The Federal Aviation Administration grounded the company’s Falcon 9 rockets and ordered an investigation following the predawn accident off the Florida coast. No injuries or public damage were reported.

It’s too early to know how much impact this will have on SpaceX’s upcoming crew flights, one private and the other for NASA. A billionaire’s chartered flight was delayed just a few hours earlier because of a poor weather forecast.

The rocket blasted off from Cape Canaveral Space Force Station and got all 21 Starlink internet satellites to orbit. But the first-stage booster fell over in a fireball moments after landing on an ocean platform, the first such accident in years. It was the 23rd time this particular booster had launched, a recycling record for SpaceX.
