Cygnus” Advanced Maneuvering Space Vehicle, Which Is Designed to Meet the Stringent Safety Requirements for International Space Station (ISS) Operations

Commercial Cargo Operations for the ISS Frank L. Culbertson Executive Vice President Low Earth Orbit Cargo Operations • Under the joint NASA / Orbital Commercial Orbital Transportation Services (COTS) program, Orbital has developed the “Cygnus” Advanced Maneuvering Space Vehicle, Which is Designed to Meet the Stringent Safety Requirements for International Space Station (ISS) Operations. • Developed through Space Act Agreement with NASA’s Commercial Crew and Cargo Program • The Cygnus Spacecraft Will Provide Cargo Resupply to the ISS Program under the Cargo Resupply Services Contract • 8 CRS Flights from 2014 to 2016 2 Leveraging Commercial Cargo to Lower Launch Costs The Cygnus vehicle is comprised of two major elements Pressurized Cargo Module (PCM) Heritage: Multi-Purpose Logistics Module (ISS); ATV Total Cargo Mass: 2,000 kg, 2700 kg Pressurized Volume: 18.7 m3, 27 m3 +X Berthing at ISS: Node 2 Common Berthing Mechanism Service Module (SM) Heritage: Orbital GEO and LEO missions Power Generation: 2 Fixed Wing Solar Arrays, 120.9” Power Output: 3.5 kW (sun-pointed) 150.1” Propellant: Dual-mode 200.2“ Compatible with Antares +Y Ø103.3” 3 © 2014 Orbital Sciences Corporation.
