Orbital-2, also known as Orb-2, was the third flight of the Orbital Sciences' uncrewed resupply spacecraft Cygnus, its third flight to the International Space Station, and the fourth launch of the company's Antares launch vehicle. The mission launched from the Mid-Atlantic Regional Spaceport (MARS) on 13 July 2014 at 16:52:14 UTC.
This was the second of eight scheduled flights by Orbital Sciences under the Commercial Resupply Services (CRS-1) contract with NASA. It was the last planned usage of the enhanced Castor 30B second stage for this CRS Orb-x series.
The mission was originally scheduled to launch on 1 May 2014 but the launch was delayed to 6 May 2014, then to 17 June 2014, then to 1 July 2014, again to 10 July 2014, again to 11 July 2014 due to test stand failure of an AJ-26 engine, to 12 July 2014 due to weather, and finally to 13 July 2014, again due to weather. Orb-2 launched on 13 July 2014 at 16:52:14 UTC with berthing to the ISS following 3 days later on 16 July 2014. The Cygnus Orb-2 delivered 1,650 kg (3,640 lb) of cargo to ISS and disposed of about 1,470 kg (3,240 lb) of trash through destructive reentry.
