Live coverage: Falcon 9 disintegrates after launch

SpaceX’s Falcon 9 booster is set for liftoff from Cape Canaveral on Sunday morning, but most of the launcher’s ascent into orbit will be under a news blackout at the request of the National Reconnaissance Office, the secretive U.S. government intelligence agency whose mission is riding on the rocket.

Wrapping up SpaceX’s fourth operational resupply flight to the International Space Station, a Dragon cargo capsule departed the high-flying research complex, dropped out of orbit and descended to a parachute-assisted splashdown in the Pacific Ocean with nearly 3,300 pounds of biological specimens and hardware.

Rainy weather expected across Central Florida this weekend has a 50-50 chance of preventing the launch of a SpaceX Falcon 9 rocket Saturday on a resupply mission to the International Space Station, U.S. Air Force forecasters said Wednesday.
