Antares launch rescheduled

Orbital Sciences said the next attempt to test launch its Antares rocket from NASA's Wallops Flight Facility, Wallops Island, Va., will be no earlier than Friday. Orbital Science is one of the commercial companies chosen by NASA to shuttle cargo to the International Space Station. This will be the first launch of the two-stage Antares, which was to have launched Wednesday until a data cable popped loose and forced a delay. The plan is to hit an orbit of 155 miles.
