Updated Launch Date, NASA TV Coverage for Orbital Sciences Demonstration Mission

Orbital Sciences Corp of Dulles, Va , will postpone by at least 24 hours the launch of its Antares rocket and Cygnus spacecraft on a demonstration mission to the International Space Station The new launch window is targeted for Wednesday, Sept 18 between 10:50 to 11:05 a m EDT from the Mid-Atlantic Regional Spaceport Pad-0A at NASA's Wallops Flight Facility in eastern Virginia
