NASA Television will broadcast live July 12 at 1:14 pm (EDT) Orbital Sciences' mission to resupply the International Space Station.
NASA will launch Orbital's Cygnus cargo spacecraft from the Mid-Atlantic Regional Spaceport's Launch Pad 0A at NASA's Wallops Flight Facility in Virginia on Saturday.
Weather conditions at Wallops delayed the scheduled rollout of Orbital's Antares rocket to the launch pad Wednesday, prompting the company to delay launch by a day.
NASA TV will air a comprehensive video feed of launch preparations and other footage related to the mission beginning at noon. Launch coverage on NASA TV will begin at 12:30 p.m.
The Cygnus will be filled with approximately 3,300 pounds of supplies for the station, including science experiments to expand the research capability of the space station's Expedition 40 crew members aboard the station, crew provisions, spare parts and experiment hardware, NASA said.
