Orbital Sciences Corp. has postponed the launch of its Cygnus cargo spacecraft to the International Space Station until 1:14 p.m. EDT on Saturday, July 12, due to weather conditions that delayed the roll-out of the Antares rocket to the Mid-Atlantic Regional Spaceport’s Pad 0A at NASA’s Wallops Flight Facility in Virginia.
Roll-out of the rocket has been rescheduled for Thursday morning.
NASA Television coverage of Saturday’s launch will begin at 12:30 p.m.
If Cygnus launches on Saturday, rendezvous will still occur on Tuesday, July 15, with grapple scheduled at 7:24 a.m. Rendezvous coverage will begin at 6:15 a.m., followed by berthing coverage at 9:30 a.m.
Cygnus is filled with about 3,300 pounds of supplies for the station, including science experiments to expand the research capability of the Expedition 40 crew, crew provisions, spare parts and experiment hardware.
