Dulles, Virginia-based Orbital ATK´s (NYSE: OA) Cygnus spacecraft has completed rendezvous and berthing with the International Space Station, marking the company´s seventh cargo delivery mission under NASA´s Commercial Resupply Services (CRS-1) contract, and fourth trip to the space station in little over a year, the company said.
Cygnus arrived at the station with approximately 7,600 (3,450 kilograms) of cargo. The crew is now scheduled to open Cygnus´ hatch and make initial ingress into the cargo module to begin unloading the pressurized cargo. The S.S. John Glenn will remain berthed with the orbiting laboratory for three months before departing with close to 3,300 pounds (1,500 kilograms) of disposable cargo.
Pending NASA´s specific cargo needs, Orbital ATK is prepared to launch two additional CRS missions scheduled this year that will launch aboard the company´s Antares rockets from NASA´s Wallops Flight Facility in Virginia.
