Orbital Sciences Corporation (NYSE: ORB), one of the world’s leading space technology companies, today announced it successfully launched its Antares™ medium-class rocket carrying the first of eight Cygnus™ cargo logistics spacecraft missions to the International Space Station (ISS) as part of its $1.9 billion Commercial Resupply Services (CRS) contract with NASA. The launch of Orbital’s Antares rocket and Cygnus cargo logistics spacecraft will culminate in rendezvous and berthing with the ISS on Sunday, January 12 at approximately 6:00 a.m. (EST). Cygnus will deliver approximately 2,780 lbs. (1,260 kg.) of cargo to the Expedition 38 astronauts and remain attached to the station until February 18 before departing with approximately 2,800 lbs. (1,300 kg.) of disposable cargo for a safe, destructive reentry over the Pacific Ocean.
Lift-off of Orbital’s Antares rocket occurred today at 1:07 p.m. (EST) from NASA’s Wallops Flight Facility in eastern Virginia. Following a 10-minute ascent, the Cygnus spacecraft was successfully deployed by the Antares upper stage and placed into its intended orbit of about 135 x 175 miles (220 X 280 km) above the Earth, inclined at 51.6 degrees to the equator. Approximately 25 minutes later, Orbital’s engineering team confirmed that reliable communications had been established and that the solar arrays were fully deployed, providing the necessary electrical power to command the spacecraft.
“It was another excellent launch of Antares, and so far, our first CRS mission is off to a great start with Cygnus operating exactly as anticipated at this early stage of the mission,” said Mr. David W. Thompson, Orbital’s President and Chief Executive Officer. “Our team has put in a lot of hard work to get to the point of performing regular ISS cargo delivery trips for NASA. It’s an exciting day for all of us and I’m looking forward to completing this and our future CRS missions safely and successfully for our NASA customer.”
