Following the successful completion of the COTS demonstration mission, Orbital will begin to carry out operational missions under the $1.9 billion Commercial Resupply Services (CRS) contract with NASA. The company will deliver approximately 20,000 kg of cargo to the ISS on eight more Antares/Cygnus missions through 2016. Each Cygnus cargo ship will carry crew food, clothing and other supplies; spare parts and equipment; and scientific experiments to the space station.About Cygnus Orbital developed the Cygnus cargo spacecraft as part of its COTS joint research and development initiative with NASA. Cygnus consists of a common Service Module (SM) and a Pressurized Cargo Module (PCM). The SM incorporates avionics, power, propulsion and communications systems already successfully flown aboard dozens of Orbital’s LEOStar™ and GEOStar™ satellites. The PCM, designed and built by Thales Alenia Space under a subcontract from Orbital, is based on the Multi-Purpose Logistics Module (MPLM) previously used with the Space Shuttle. With a full load of cargo and fuel, the standard-configuration Cygnus weighs about 5,200 kg at launch and generates 3.5 kw of electrical power while in orbit. It is capable of extended-duration missions of a year or longer in space.
