Cygnus CRS Orb-2,[3][4] also known as Orbital Sciences CRS Flight 2, is the third planned flight of the Orbital Sciences' unmanned resupply spacecraft Cygnus, its third flight to the International Space Station and the fourth launch of the company's Antares launch vehicle.


This is the second of eight scheduled flights by Orbital Sciences under the Commercial Resupply Services contract with NASA. The mission was scheduled to launch on May 1, 2014.[2] The launch has been delayed, no sooner than May 6, due to delays in SpaceX CRS-3 launch from Cape Canaveral.[5] The Cygnus is expected to deliver 1,650 kilograms (3,630 lb) of cargo to ISS and dispose of about 1,470 kilograms (3,250 lb) of trash through destructive reentry.[6]
