Lift-off of Orbital’s Antares rocket occurred Thursday 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 between and the module.
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.
Over the next two and a half days, Cygnus will perform a series of engine firings to put it on track for a Sunday morning rendezvous with the station. When the vehicle reaches the capture point about 30 feet from the complex, Expedition 38 Flight Engineers Mike Hopkins and Koichi Wakata will use Canadarm2, the station’s 57-foot robotic arm, to reach out and grapple Cygnus at 6:02 a.m. The crew then will use the robotic arm to guide Cygnus to its berthing port on the Earth-facing side of the Harmony node for installation beginning around 6:20 a.m.
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 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.
Under the Commercial Orbital Transportation Services (COTS) joint research and development initiative with NASA, Orbital developed the Cygnus spacecraft, which is an advanced maneuvering vehicle that meets the stringent human-rated safety requirements for ISS operations.
Cygnus consists of a common Service Module (SM) and a Pressurized Cargo Module (PCM). The SM incorporates avionics, power and propulsion systems already successfully flown aboard dozens of Orbital’s LEOStar™ and GEOStar™ satellite products. The PCM, designed and built by Thales Alenia Space under a subcontract from Orbital, is based on the Multi-Purpose Logistics Module (MPLM) used with the Space Shuttle.
The Antares rocket can launch spacecraft weighing up to 14,000 lbs. into low-Earth orbit, and light payloads into higher geosynchronous orbits.
