![]() NASA insignia Commercial Resupply Services Cygnus flights |
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.
In an Orbital Sciences tradition, the Cygnus spacecraft was named the S.S. Janice Voss after Janice E. Voss, a NASA astronaut and Orbital employee who died on 6 February 2012.[6]
The mission was originally scheduled to launch on 1 May 2014[7] 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.[8] 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.[9] 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.[10]
Total weight of cargo: 1,650 kg (3,640 lb)[3][11]
