The original rendezvous schedule was postponed by 24 hr. and then until Sept. 29 to await the Sept. 25 launch and docking of Russia’s Soyuz TMA-10M with three new ISS crewmembers.

During the delay, Orbital fashioned a one-line software change that was uplinked and verified, allowing Cygnus to march through the final milestones during the last 10 hr. of the rendezvous. They included a successful command exchange from the ISS crew in which Cygnus was instructed to advance from a 250-meter hold point below the station to a separation of 230 meters, where it held for several minutes.
