Live coverage: Falcon 9 disintegrates after launch

SpaceX’s Falcon 9 rocket was poised for launch Wednesday at Cape Canaveral’s Complex 40 launch pad carrying more than 5,600 pounds of supplies and experiments to the International Space Station.

Ready for a resupply run to the International Space Station, a SpaceX Falcon 9 rocket was raised vertical at Cape Canaveral’s Complex 40 launch pad Wednesday ahead of a planned liftoff with more than 5,700 pounds of science experiments and crew supplies.

SpaceX’s launch team loaded liquid propellants into the company’s first upgraded Falcon 9 Block 5 rocket Friday at the Kennedy Space Center in Florida, and the countdown rehearsal culminated in a brief ignition of the launcher’s nine Merlin main engines on the launch pad.
