Gallery: Antares rocket explodes

Orbital ATK launch managers have pushed back liftoff of an Antares rocket until Monday to replace a faulty cable on the booster’s launch pad in Virginia.

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.

The 15th resupply mission to the International Space Station by a Cygnus cargo freighter lifted off at 12:36 p.m. EST (1736 GMT) Saturday aboard an Antares rocket from Wallops Island, Virginia. The Northrop Grumman-owned spacecraft is carrying more than 8,000 pounds of experiments and provisions for the space station and its seven-person crew. Capture by the station’s robotic arm occurred at 4:38 a.m. EST (0938 GMT) Monday.
