Live coverage: Falcon 9 disintegrates after launch

Orbital ATK shipped the final major piece of hardware for the next Cygnus space station resupply mission to a launch base on Virginia’s Eastern Shore last week as technicians began loading cargo destined for delivery to the orbiting research lab.

SpaceX has delayed the next launch of a Falcon 9 rocket from pad 39A at the Kennedy Space Center until Sunday. The two-stage launcher will carry with another batch of 60 Starlink satellites into orbit.

The launch of a United Launch Alliance Delta 4-Heavy rocket from Cape Canaveral was aborted three seconds before a planned liftoff at 3:28 a.m. EDT (0728 GMT). The rocket was set to loft a classified payload for the National Reconnaissance Office, the U.S. government’s spy satellite agency.
