Gallery: Antares rocket explodes

Facing pressure to find a ride into space for its commercial Cygnus cargo craft in the wake of a catastrophic rocket failure, Orbital Sciences Corp. says it has found openings in the mission manifests of the world’s busiest launch operators to accommodate resupply flights to the International Space Station next year.

A Northrop Grumman Antares rocket rolled out of its hangar Monday night, riding a self-propelled transporter for a mile-long trip to launch pad 0A on Wallops Island, Virginia, for a predawn liftoff Thursday with a Cygnus supply ship heading for the International Space Station.

Residents along the U.S. East Coast from South Carolina to Massachusetts could glimpse Orbital ATK’s Antares rocket climbing into space Monday night on a cargo run to the International Space Station.
