Mission Update - March 22, 2017

The launch of the United Launch Alliance Atlas V rocket carrying the OA-7 Cygnus spacecraft for Orbital ATK and NASA has been postponed. While completing testing for a ground support hydraulic condition discovered during prelaunch testing, ULA discovered a different issue with a booster hydraulic line on the Atlas V rocket. The ULA team is developing a plan to resolve the issue and a new launch date will be determined. The Atlas V and Cygnus spacecraft remain secure.

Mission Update - March 9, 2017

Orbital ATK is honored to name the OA-7 Cygnus cargo delivery spacecraft after former astronaut and U.S. Senator John Glenn. Glenn, the first American to orbit Earth, was a lifelong pioneer of human spaceflight. Glenn paved the way for America’s space program, from moon missions, to the space shuttle and the International Space Station. His commitment to America's human space flight program and his distinguished military and political career make him an ideal honoree for the OA-7 Mission. Glenn passed away on December 8, 2016 and is survived by his wife of 73 years, Annie, and their children, John and Carolyn. Read more about John Glenn here.

About the Mission

The OA-7 mission is targeted to launch no earlier than March 27 from Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida. Orbital ATK will launch Cygnus atop a United Launch Alliance (ULA) Atlas V rocket for delivery of essential crew supplies, equipment and scientific experiments to astronauts aboard the International Space Station.

Cygnus will carry the SAFFIRE-3 space combustion experiment from NASA’s Glenn Research Center that will intentionally burn a single large sample of material to study flame development in space. Cygnus will also carry the Reentry Data Collection (RED-Data-2) flight recorder to provide crucial data about the extreme conditions a spacecraft encounters during atmospheric reentry.

OA-7 will mark Orbital ATK’s seventh cargo delivery mission for NASA under its Commercial Resupply Services (CRS) -1 contract.

About Cygnus

Cargo is delivered to the station using Orbital ATK’s Cygnus spacecraft. The Cygnus spacecraft consists of two modules: the Service Module (SM) which incorporates the avionics, propulsion and power systems from Orbital ATK’s flight proven LEOStar and GEOStar spacecraft buses; and the Pressurized Cargo Module (PCM) which carries the crew supplies, spares and scientific experiments. The SM is integrated and tested at Orbital ATK’s Dulles, Virginia satellite manufacturing facility. The PCM is supplied by Thales Alenia Space and is produced in Turin Italy.
