The Antares rocket launched the Cygnus spacecraft loaded with approximately 7,400 pounds (3,350 kilograms) of cargo to the crew of six who are aboard the space station. Following an approximate nine-minute ascent, the "S.S. Gene Cernan" Cygnus spacecraft, named in honor of the late astronaut and the last man to leave the moon, was successfully deployed into orbit. Orbital ATK's engineering team confirmed reliable communications have been established and the vehicle's solar arrays are fully deployed, providing the necessary electrical power to operate the spacecraft.

"While the Antares team celebrates a successful launch today, we're already well into building the vehicles for the next two missions," said Scott Lehr, President of Orbital ATK's Flight Systems Group. "We will be ready to launch again whenever Cygnus needs us."

Cygnus will be grappled at approximately 4:50 a.m. EST on November 14. The spacecraft will remain attached to the space station for approximately three weeks before departing with more than 4,000 pounds (approximately 2,000 kilograms) of disposable cargo. Cygnus' large-volume disposal capability, a critical service to NASA, is unique among America's commercial cargo providers.

"Today's successful launch of the OA-8 Cygnus on our Antares launch vehicle once again demonstrates the reliability of Orbital ATK's hardware along with our commitment to deliver critical cargo to astronauts on the International Space Station," said Frank Culbertson, President of Orbital ATK's Space Systems Group. "Soon, Cygnus will rendezvous with the space station to deliver valuable scientific experiments, hardware and crew supplies to the orbiting platform."

"On this mission, Cygnus will again display its flexibility as an in-orbit science platform by supporting experiments to be performed inside the cargo module while attached to the space station. We are proud to dedicate this mission to Apollo astronaut Gene Cernan and his family and look forward to celebrating the OA-8 contributions to science in his name," said Culbertson.

Upon arrival at the space station, the "S.S. Gene Cernan" Cygnus will be unloaded and used for the first time as an extension of the orbiting laboratory for an experiment featuring a SpaceTango facility. TangoLab is a reconfigurable general research facility designed for microgravity research and development. This exercise will highlight the ability to expand the station's capabilities for hosting experiments using the Cygnus module.

During the three weeks Cygnus remains docked, the astronauts on the space station will perform the transfer of the lab to Cygnus and then back to the station where it will remain. Once Cygnus is unberthed, a NanoRacks deployer will release 14 Cubesats, a record number for the spacecraft. Upon completion of its secondary missions, Cygnus will perform a safe, destructive reentry into Earth's atmosphere over the Pacific Ocean.

SS Gene Cernan arrives at space station

The S.S. Gene Cernan, Orbital ATK's eighth Cygnus cargo spacecraft to deliver supplies and science for the crew on board the International Space Station, completed a two-day flight to the outpost on Tuesday morning (Nov. 14).

Expedition 53 flight engineer Paolo Nespoli of ESA (the European Space Agency), working with commander Randy Bresnik of NASA, captured the S.S. Gene Cernan using the space station's Canadarm2 robotic arm at 4:04 a.m. CST (1004 GMT).

With the Cygnus in grasp, flight controllers at NASA's Mission Control Center in Houston guided the spacecraft to a berthing on the Earth-facing port of the station's Unity module, where it will remain attached for the next three weeks.

Cygnus departed from the International Space Station on Dec. 6 at 8:11 a.m. EST [1311 GMT] following a highly successful stay at the orbiting laboratory.

The spacecraft is packed with approximately 6,400 pounds [2,900 kilograms] of disposable cargo, the largest amount of material ever removed by Cygnus during its cargo resupply missions. After its departure, the S.S. Gene Cernan successfully released 14 cubesats from a NanoRacks cubesat deployer on board.

The OA-8 mission is expected to end on Dec. 18 when Cygnus will execute a safe, destructive reentry into Earth's atmosphere over the Pacific Ocean.
