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.Orbital privately developed the Antares launch vehicle to provide low-cost, reliable access to space for medium-class payloads. It is the largest and most complex rocket the company has ever produced. Under the Commercial Orbital Transportation Services (COTS) joint research and development initiative with NASA, Orbital also developed the Cygnus spacecraft, which is an advanced maneuvering vehicle that meets the stringent human-rated safety requirements for ISS operations. Together, these products showcase Orbital’s ability to apply rigorous engineering approaches and commercial business practices to significantly shorten development timelines and lower operational costs of sophisticated space systems as compared to traditional government-run programs. About Antares The Antares medium-class launch vehicle will provide a major increase in the payload launch capability that Orbital can provide to NASA, the U.S. Air Force and commercial customers. The Antares rocket will launch spacecraft weighing up to 14,000 lbs. into low-Earth orbit, as well as lighter-weight payloads into higher-energy orbits. Orbital’s newest launcher is currently on-ramped to both the NASA Launch Services-2 and the U.S. Air Force’s Orbital/Suborbital Program-3 contracts, enabling the two largest U.S. government space launch customers to order Antares for “right-size and right-price” launch services for medium-class spacecraft.

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 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.
