Excerpt:
Quote
This morning, at around 1:30 a.m. EDT, Cygnus established direct data contact with the 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.

Not sure if NASA TV will still go live in five mins - even if it's a short update now - or not at all.

Offline Chris Bergin

And the answer to that is no, NASA TV coverage just running through with video file.

Looks hopeful on the software solution, so we'll keep this thread going until the next attempt.

NASA giving the ISS crew an off duty day. Cygnus on Tuesday and next crew preps Wednesday.

Any word on what the last day to complete the rendezvous and berthing is before it would have to move to the other side of the Soyuz?

Bill Harwood covered it in his story, it is Tuesday:

(I forgot about the four-orbit Soyuz rendezvous.)

Following the discovery of a data format discrepancy between an on-board International Space Station (ISS) navigation system and a similar system on Cygnus at around 1:30 a.m. this morning, today's rendezvous with the station was postponed. At this time, NASA and Orbital are developing a detailed plan for a second rendezvous attempt early Tuesday morning.

A software update has been developed and will be tested on a ground-based simulator during the day on Sunday. Upload to Cygnus and in-orbit testing of the software "patch" is planned for Sunday night and into Monday morning. Once this has been accomplished and verified, the current plan is for Cygnus to begin a second rendezvous approach late Monday night, with final approach to the ISS and grapple taking place early Tuesday morning. The Cygnus spacecraft remains healthy, with all major subsystems operating as expected.

Karen is disassembling the HCP with MCC-H approval and returning it to the JEM.

15 km, the crew is up but have not responded to the first call from MCC-H of the morning


This call turned out to be the rendezvous abort notification.  Interestingly, CAPCOM stated "no hurry, at your convenience." It was before the DPC which usually denotes the start of MCC interaction with the crew.

CAPCOM stated to Luca there will be an update on Cygnus status for the crew during the evening DPC.

MCC-H = Houston (JSC)
MCC-D = Dulles
In satellite operations, schedules are governed by the laws of physics and bounded by the limits of technology.

is NOT real time data--it currently shows Cygnus at 25 meters under ISS  :o

This was known all along. it runs on  "nominal mission data" - ie a set of perfectly executed manouvres right on time. The website does not, and never has, received real-time telemetry.
But if you want to continue this, better move to discussion thread instead of updates.

Heavens Above is now showing Cygnus ahead of the ISS.  Is it going to go around and catch up to it again?
Nominal now means "Yeehah!!"

My calculations suggest the 4 km flyby of ISS happened at 0845 UTC approximately.

I'd imagine Cygnus will have to raise its altitude to allow the ISS to go ahead of it, then lower its altitude again to catch up on Tuesday.

Still thinks grappling and berthing occurred as scheduled this morning.

ISS crew was just told that MCC-H is still planning toward a Tuesday (9/24) rendezvous and berthing.  However, a Tuesday rendezvous is not definite yet.

No confirmation of re-attempt on Tuesday yet from the DPC.

The facility in Hawthorne is MCC-X.  Sometimes they are a little too cute.
