Mission Update

December 18, 2017

Orbital ATK's S.S. Gene Cernan Cygnus spacecraft successfully completed its eighth cargo supply mission to the International Space Station under NASA’s Commercial Resupply Services (CRS-1) contract. The OA-8 mission officially concluded on December 18 at 7:54 a.m. EST when Cygnus performed a safe, destructive reentry into the Earth’s atmosphere over the Pacific Ocean east of New Zealand. The spacecraft remained docked for 22 days at the orbiting laboratory and departed the space station on December 6. Read the press release here.

December 6, 2017

Cygnus departed from the International Space Station on December 6 at 8:11 a.m. EST following a highly successful stay at the orbiting laboratory. The spacecraft is packed with approximately 6,400 pounds 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 December 18 when Cygnus will execute a safe, destructive reentry into Earth’s atmosphere over the Pacific Ocean.

The hatch to the S.S. Gene Cernan has been opened by crew members aboard the International Space Station and they are beginning to unload the cargo. During its stay at the orbiting laboratory, after demonstrating its versatility as an in-orbit science platform, the spacecraft will be used as an extension of the space station by hosting experiments that will be conducted inside the Cygnus cargo module while attached to the space station. Cygnus is scheduled to stay at the station until December 4. After it unberths, 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.

November 14, 2017

The S.S. Gene Cernan Cygnus spacecraft successfully completed its rendezvous and berthing maneuvers with the International Space Station at 7:15 a.m. EST on November 14. Cygnus arrived at the station with approximately 7,400 pounds (3,350 kilograms) of cargo, supplies and scientific experiments. Cygnus will remain docked at the station for approximately three weeks before departing on secondary missions. Read the press release here.

November 12, 2017

Orbital ATK successfully launched its OA-8 mission aboard the company's Antares rocket from NASA's Wallops Flight Facility on November 12, 2017 at 7:19 a.m. EST. Cygnus rendezvous is scheduled for early morning Tuesday, November 14, with grapple at approximately 4:50 a.m. EST. Live coverage will begin at 3:15 a.m. EST on NASA TV. The spacecraft will deliver vital supplies and scientific equipment to the station as part of Orbital ATK’s Commercial Resupply Services (CRS) contract with NASA.

About Antares

Designed to provide responsive and low-cost access to space, Antares is a two-stage vehicle (with optional third stage) that provides low-Earth orbit (LEO) launch capability for payloads weighing up to 8,000 kg. Internally funded by Orbital ATK, Antares completed a risk reduction mission and a demonstration of commercial re-supply services for the International Space Station (ISS) under a NASA Commercial Orbital Transportation Services (COTS) agreement in 2013. Orbital ATK commenced delivery of cargo to the ISS under the NASA Commercial Resupply Services (CRS) contract in 2014.

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.

S.S. Gene Cernan

Orbital ATK has named the OA-8 Cygnus Cargo Delivery Spacecraft after former astronaut Eugene “Gene” Cernan. As the last human to step foot on the moon, Cernan set records for both lunar surface extravehicular activities and longest time in lunar orbit, paving the way for future human space exploration.
