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.

Engineers erected a commercial Antares rocket vertical on its launch pad on Virginia’s Eastern Shore Friday, positioning the 13-story booster for liftoff Sunday night with more than 5,000 pounds of supplies and experiments for the International Space Station.

The Antares rocket, Orbital ATK’s medium-class booster now with modern RD-181 engines, launches at 7:45 p.m. EDT (2345 GMT) from NASA’s Wallops Flight Facility on the eastern shore of Virginia.
