Expedition 37 crew members aboard the International Space Station released Orbital Sciences' Cygnus spacecraft from the station's robotic arm at 7:31 a.m. EDT on October 22, 2013. Orbital Sciences engineers then conducted a series of planned burns and maneuvers to move Cygnus toward a destructive re-entry in Earth's atmosphere Wednesday, October 23.
Cygnus had been attached to the space station's Harmony module for 23 days. The spacecraft delivered about 1,300 pounds (589 kilograms) of cargo, including food, clothing and student experiments, on a demonstration cargo resupply mission to the station.
Cygnus was launched on Orbital's Antares rocket on September 18 from the Mid-Atlantic Regional Spaceport Pad-0A at NASA’s Wallops Flight Facility in Virginia.
