Orbital ATK (NYSE:OA), a global leader in aerospace and defense technologies, announced it successfully completed its sixth cargo delivery mission to the International Space Station for NASA. Known as OA-5, the mission marked the company's return to flight operations from NASA's Wallops Flight Facility in Wallops Island, Virginia and the second time Cygnus™ has been used as a platform for conducting research in space. "The OA-5 mission was filled with numerous accomplishments," said Frank Culbertson, President of Orbital ATK's Space Systems Group. "We returned to flight operations at our home base in eastern Virginia, successfully launched aboard our upgraded Antares rocket and once again showcased Cygnus' dynamic versatility and value to serve as a platform for conducting science experiments and payload operations for key customers. I congratulate the entire NASA and Orbital ATK teams for a job well done." On November 27 at approximately 6:40 p.m. EST, Cygnus performed a safe, destructive reentry into Earth's atmosphere over the Pacific Ocean east of New Zealand, successfully concluding the OA-5 mission. Named the "S.S. Alan Poindexter" in honor of the two-time Space Shuttle veteran, Cygnus launched on October 17, and six days later, berthed with the International Space Station, delivering approximately 5,300 pounds (2,400 kilograms) of vital supplies and science experiments to the astronauts on board. It remained docked for 29 days and departed the space station on November 21. Prior to its departure, the astronauts loaded the cargo module with approximately 2,469 pounds (1,120 kilograms) of items for disposal. After departing the space station, Cygnus moved into its next phase of serving as an in-orbit science platform. It successfully executed the Saffire-II payload experiment and deployed four CubeSats that will be used for meteorological research. The mission marked the first time that a cargo spacecraft deployed satellites above the orbit of the International Space Station.
