Live coverage: Falcon 9 disintegrates after launch

Nine Merlin main engines at the base of a SpaceX Falcon 9 rocket fired at launch pad 39A Saturday, passing a major test before the company’s next launch, a secretive mission slated for liftoff Wednesday night.

Technicians planned to attach two Boeing-built communications satellites to a SpaceX Falcon 9 rocket Monday, a day after launch controllers fueled the rocket and fired its nine Merlin first stage engines in a key preflight test.

The beginning of November will be the earliest SpaceX’s Falcon 9 rocket can resume launching after a June 28 failure blamed on a deficient structural support brace inside the the vehicle’s second stage, a SpaceX executive said Monday.
