Orbital Sciences Hits Key Milestones Toward ISS Cargo Flights

An update from Orbital Sciences Corporation:

As the year draws to a close there are now three substantially complete Cygnus Service Modules in Orbital’s Dulles, Virginia Satellite Manufacturing Facility (see photo below). In addition to the integration and testing of the spacecraft, the program has achieved a number of key milestones in the last few months:

Mission Operations to Spacecraft Testing: The Orbital team successfully completed the first test of the Mission Operations to Spacecraft link. The COTS demo service module was attached via data and command lines to Orbital’s Mission Operations Center in Dulles, Virginia, and the mission timeline from launch to berthing was exercised by the Cygnus team. This test required the team to operate in shifts, flying the spacecraft continuously for approximately 80 hours to simulate all required maneuvers to achieve ISS berthing, successfully executing all required procedures.
