Cygnus Rendezvous Postponed Until Sunday

Managers from Orbital Sciences and NASA decided Monday morning to postpone the approach, rendezvous, grapple and berthing operations of Orbital's Cygnus cargo logistics spacecraft with the International Space Station to no earlier than Saturday, Sept. 28. Cygnus' rendezvous now will follow the launch and arrival of three crew members of Expedition 37-38 on Wednesday.

Orbital has confirmed that over the past 24 hours, the Orbital team developed and tested a software fix for the data format mismatch that necessitated a postponement of the first rendezvous operation that was scheduled for the early morning of Sunday, Sept. 22. 

However, that process, together with the impending Soyuz crew operations, resulted in a tight schedule to the point that both Orbital and NASA felt it was the right decision to postpone the Cygnus approach and rendezvous until after Soyuz operations.
