Cygnus Spacecraft Under Construction

Photo: Integration and Testing of Cygnus Service Modules
“Integration and testing of Cygnus spacecraft service modules continues at our Dulles, VA Satellite Manufacturing Facility (SMF). The service module on the left in the photo below will be used for the Commercial Orbital Transportation Services (COTS) demonstration flight to the International Space Station (ISS) later this year. The service module on the right will carry out the first of eight cargo resupply missions under Orbital’s Commercial Resupply Services (CRS) contract with NASA, also scheduled for later this year. A third Cygnus service module (not shown) is also undergoing integration in a separate clean room facility in the facility.”
