The Federal Aviation Administration has grounded SpaceX's Falcon 9 rockets pending an investigation to determine what caused a first-stage booster to crash onto a landing barge early Wednesday after helping launch another batch of Starlink internet satellites.
After standing down from the piloted Polaris Dawn launch late Tuesday because of an unfavorable long-range forecast, SpaceX pressed ahead with the first of two planned back-to-back launches of Starlinks, one from Florida and the other from California.
But the second flight was called off after the first stage used in the Florida launch crash-landed and toppled into the Atlantic Ocean while attempting to touch down on a SpaceX droneship stationed several hundred miles northeast of Cape Canaveral.

It's an evocative idea that has long bedeviled scientists: a huge and mysterious planet is lurking in the darkness at the edge of our solar system, evading all our efforts to spot it. Some astronomers say the strange, clustered orbits of icy rocks beyond Neptune indicate that something big is out there, which they have dubbed "Planet Nine."
