Orbital Sciences launched July 13, 2014 after more then a month delay. It launched at the opening of it’s 5 minute window at 12:52 local time (16:52 UTC) from Pad 0A at the Mid-Atlantic Regional Spaceport on NASA’s Wallops Flight Facility.
The Antares rocket with their third Cygnus spacecraft is a commercial resupply mission headed for the International Space Station with some much anticipated food and supplies. 
At a Launch Readiness Review Saturday, managers for Orbital Sciences Corp. of Dulles, Virginia, and NASA gave a “go” to proceed toward the Sunday, July 13 launch of the Orb-2 cargo resupply mission to the International Space Station. Orbital is targeting a 12:52 p.m. EDT launch from the Mid-Atlantic Regional Spaceport Pad 0A at NASA’s Wallops Flight Facility in Virginia. NASA Television coverage of the launch will begin at noon.
There is a 90 percent chance of favorable weather at the time of launch.
NASA TV will broadcast a prelaunch news briefing today from the Wallops visitors center at 4:30 p.m. The briefing will be carried live on NASA TV and the agency’s website at http://www.nasa.gov/ntv.

Mission Update – July 3, 2014
Orbital has established July 11, 2014 as the targeted date for the launch of the Orb-2 mission to the International Space Station (ISS), the second operational cargo resupply mission under the company’s Commercial Resupply Services (CRS) contract with NASA. The targeted launch time from the Mid-Atlantic Regional Spaceport at NASA’s Wallops Flight Facility on July 11 will be 1:40 p.m. (EDT).
The engineering team that is investigating the failure of an AJ26 engine during an acceptance test at Stennis Space Center recommended that certain inspections be performed on the two AJ26 engines that are currently integrated on the Antares rocket. These inspections were recently completed and program officials have cleared the rocket for flight.
Leading up to the launch, the Cygnus cargo logistics spacecraft will be mated to the rocket today. After the loading of the final time sensitive cargo and installation of the rocket’s payload fairing, Antares will be rolled out to the launch pad on July 9. A launch on July 11 will result in a rendezvous and berthing with the ISS on July 15. The Cygnus spacecraft will deliver 1,657 kg of cargo to the ISS and will be loaded with approximately 1,346 kg of material for disposal upon reentry into Earth’s atmosphere.
