Shipping of Cygnus Service Module Marks Key Milestone for OA-4 Mission

 

 

On October 12, Orbital ATK shipped the Cygnus spacecraft’s service module to NASA’s Kennedy Space Center for the next International Space Station (ISS) cargo mission, scheduled to launch later this year aboard a United Launch Alliance Atlas V rocket. This OA-4 mission milestone marks a key step forward as Orbital ATK continues its cargo delivery service to the ISS for NASA under the Commercial Resupply Services (CRS) contract.

The service module, which houses the spacecraft’s avionics, electrical, propulsion and communications systems, arrives at Kennedy on October 13 where it will be integrated with the extended pressurized cargo module (PCM) that is already in place.

A Mission of Firsts

The mission marks the first flight of the enhanced variant of the Cygnus spacecraft, which is capable of delivering more than 7,700 pounds of essential crew supplies, equipment and scientific experiments to astronauts on board the ISS. The PCM’s capability to deliver larger volumes of cargo to the station aboard the powerful Atlas V provides even greater support to NASA’s continued research and utilization of the ISS.

The spacecraft will also use the latest in lightweight space-qualified power system technology with the addition of the company’s UltraFlex solar arrays. OA-4 marks the first mission to use the UltraFlex solar arrays which were produced by Orbital ATK’s Space Components Division.

Looking Ahead

While preparations continue for OA-4 later this year, three CRS missions are scheduled for 2016 to support NASA’s ISS cargo needs, leading off with a second Atlas V launched mission from Kennedy Space Center in the spring, followed by the return of operations to the Wallops Flight Facility in the first half of the year where the company will continue CRS missions on an upgraded Antares. The PCMs and Service Modules for the three 2016 Cygnus spacecraft missions are essentially complete and will be shipped to the respective launch sites a couple of months prior to their launch dates. 

“These are exciting times for the Cygnus team at Orbital ATK,” said Frank Culbertson, President of Orbital ATK’s Space Systems Group. “With OA-4 set to launch in December and at least three additional missions to the Space Station planned in 2016, we remain solidly on schedule to meet our CRS cargo requirements for NASA. Our team’s performance in meeting milestones on an accelerated timeline demonstrates the company’s flexibility and responsiveness to customer needs.”
