No confirmation of re-attempt on Tuesday yet from the DPC.
I think this is short of confirming an attempt on Tuesday but it explains the 48 hour delayCygnus Rendezvous Delayed 48 Hours. Orbital Sciences has confirmed Sunday morning, around 1:30 a.m. EDT, its Cygnus spacecraft established direct data contact with the International Space Station (ISS) and found that some of the data received had values that it did not expect, causing Cygnus to reject the data. This mandated an interruption of the approach sequence. Orbital has subsequently found the causes of this discrepancy and is developing a software fix. The minimum turnaround time to resume the approach to the ISS following an interruption such as this is approximately 48 hours due to orbital mechanics of the approach trajectory. - courtesy of NASA; more: http://www.nasa.gov/content/cygnus-rendezvous-delayed-48-hours

The crew was just advised to cancel several Cygnus related events and there was mention of more cancellations tomorrow.
Are you saying current efforts have failed? Put pay - not a very american phrase.Answered my own question, looked in British dictionary. Failed
This morning, Orbital and NASA together decided to postpone the approach, rendezvous, grapple and berthing operations of the Cygnus cargo logistics spacecraft with the International Space Station until after the upcoming Soyuz crew operations are complete. The Soyuz crew is due to arrive at the ISS very late on Wednesday, September 25. The earliest possible date for the next Cygnus approach and rendezvous with the ISS would be Saturday, September 28. An exact schedule will be determined following the successful completion of Soyuz operations.
In a NASA Spaceflight.com article (http://www.nasaspaceflight.com/2013/09/cygnus-cots-graduation-iss-berthing/), it describes the following approach to solving the GPS problem between ISS and Cygnus:"The simple fix is to add “1024″ (the difference in week numbers between the 1980 and 1999 ephemeris) to the data received from the PROX system, which only requires modification of a single instruction in the Cygnus software."However, is it really that simple? There have been 13 leap seconds between 1980 and 1999. Slapping a 1024 week offset on the code does not strike me as a very precise solution.
