ISS Commercial Resupply Services Mission (Orb-1)

Launch Date: January 9, 2014
Launch Site: Wallops Island, VA
Cygnus Berth at ISS: January 12, 2014
Cygnus Depart ISS: February 18, 2014
Mission Customer: NASA

The Antares rocket carrying Orbital’s Cygnus cargo logistics spacecraft successfully lifted-off from Pad-0A at Wallops Island, Virginia on January 9, 2014 boosting Cygnus to an initial target orbit. Cygnus used its on-board thrusters to raise its orbit to rendezvous and berth with the International Space Station (ISS) on January 12, 2014. For this mission Cygnus carried approximately 1465 kg (3,230 lbs.) of cargo to the ISS for NASA.

The Orb-1 mission was the first of eight commercial cargo resupply missions to the ISS under the NASA Commercial Resupply Services (CRS) contract, under which Orbital is slated to deliver up to 20,000 kg of supplies to the station.

Antares Mission Description

The two-stage Antares space launch vehicle utilized a liquid-fueled first stage powered by two Aerojet Rocketdyne AJ26 engines and a solid motor ATK CASTOR 30B upper stage to boost Cygnus into orbit. The powered launch sequence lasted about ten minutes from liftoff through the separation of Cygnus from the launch vehicle.

Cygnus Mission Description

After separation from Antares, Cygnus deployed its solar arrays and underwent initial check-out. The spacecraft conducted a series of thruster burns to raise its orbit to bring it within 4 km of the ISS prior to receiving authorization to autonomously rendezvous with the station. When the vehicle approached to within 12 meters, the astronauts used the station’s robotic arm to grapple Cygnus and berth it to the Harmony node of the station. Cygnus remained berthed at the ISS for 38 days during which time the station crew unloaded cargo from Cygnus and loaded it with materials for disposal. Cygnus departed the station on February 18 and reentered the Earth’s atmosphere a day later.
