Mission Update - July 16, 2014

Orbital's Cygnus spacecraft successfully completed its rendezvous and approach maneuvers with the International Space Station (ISS) and was grappled and berthed with the station by the Expedition 40 astronaut crew earlier this morning. After Cygnus was launched into orbit by Orbital’s Antares rocket on Sunday, July 13 from the Mid-Atlantic Regional Spaceport at NASA’s Wallops Flight Facility in eastern Virginia, it completed a series of thruster firings and other maneuvers bringing the spacecraft in close proximity to the ISS.

Final approach to the station began at about 3:00 a.m. (EDT) this morning, culminating with the station’s robotic arm grappling the spacecraft at 6:36 a.m. when it was about 30 feet (10 meters) from the ISS. Cygnus was then guided to its berthing port on the nadir side of the ISS’ Harmony module where its installation was completed at 8:53 a.m.

Cygnus is delivering approximately 3,669 lbs. (1,664 kg.) of cargo and science payloads. Either later today or tomorrow, the crew plans to open the Cygnus hatch and make initial ingress into its cargo module. Cygnus will remain berthed at the ISS for 30 days before departing with approximately 2,800 lbs. (1,300 kg.) of disposable cargo. Orbital will also conduct a series of in-orbit tests designed to provide data to help improve the vehicle’s performance for future uses. At the end of the mission Cygnus will reenter the Earth’s atmosphere.

About Commerical Resupply Services

Under a $1.9 billion CRS contract with NASA, Orbital will use Antares and Cygnus to deliver up to 44,000 pounds (20,000 kilograms) of cargo to the ISS over eight missions, including the mission currently underway, through late 2016. For these missions, NASA will manifest a variety of essential items based on ISS program needs, including food, clothing, crew supplies, spare parts and equipment, and scientific experiments.
