Video: Antares rocket explodes

The first sign of failure during the doomed launch of an Orbital Sciences Corp. Antares rocket from Virginia came from the rocket’s first stage about 15 seconds after liftoff.

Ground crews transferred an Antares rocket out of an assembly building to a launch pad on Virginia’s Eastern Shore in a major step before liftoff on Orbital Sciences’ third flight to resupply the International Space Station.
