Reporters run for cover as Antares rocket explodes

An Orbital ATK Cygnus supply ship packed with 3.7 tons of cargo, supplies and experiments rode an Antares rocket into orbit from Virginia’s Eastern Shore on Sunday, setting course on a two-day pursuit of the International Space Station.

Based upon an on-time launch Thursday, this is the timeline for Cygnus from liftoff through capture by the space station’s robotic arm.

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.
