PAO Josh via his Soyuz coverage notes Sunday morning is now the NET. MMTs to decide if it's possible.

Software was successfully patched last night on all flight computers. The team is looking at Sunday 9/29 at about 7:15 AM EDT for capture, pending IMMT approval.

Could be a busy day in the space business with this, Falcon 9 v1.1 launch, and Proton launch.  :)

Cygnus performed a delta-v burn a little while ago and is now "parked" abuot 2400 km behind the ISS. The team will be repeating the abort demonstration later today that they did last week. This is not required since that demo was alredy performed successfully. But they are using this as further validation that the updated software did not accidently mess anything up.

Cygnus In-Orbit Update

Thursday, September 26, 2013

The Cygnus spacecraft remains healthy in-orbit, with all major onboard systems performing as expected. Over the past several days, the Cygnus engineering team has developed, validated and uploaded the one-line software "patch" that resolved the GPS data roll-over discrepancy that was identified during the initial approach to the ISS last Saturday.

Orbital and NASA are currently discussing the best rendezvous opportunity, with the current trajectory plan supporting Sunday morning, September 29 as the next opportunity to rendezvous and approach the ISS. This schedule is still subject to final review and approval by the NASA and Orbital teams.

The Cygnus spacecraft is currently holding at about 2,400 km behind the International Space Station. Later this evening, Cygnus will perform the first of a series of thruster burns to begin the journey back towards the ISS to be in the right position for a rendezvous as early as Sunday morning.

Just waiting for IMMT approval now. They started the meeting 90 minutes ago.

New article, with help from Martin (MP99) and others when approval is confirmed.

There will be a new thread for Sunday.

Thanks.  Do you know/can you say approx. what time the RGPS demo would be attempted on Sunday morning (GMT)?

They're hoping to verify that the patch is working sometime Saturday evening. That is several hours sooner than the demo requires. But the hope is that the PROX link can close when the spacecraft is much further way ( >200 km) so they will know long before it is needed.

Because one should always remember nothing is actually official until NASA or a company say it is:

Orbital Sciences ‏@OrbitalSciences 3
#Cygnus plan to rendezvous and berth with #ISS on Sunday morning reviewed and approved.  @NASA TV begins at 4:30 a.m. for #cotsdemo mission

CAPCOM just passed word of the IMMT approval to the crew and that ingress would be Monday at 1000 GMT.  CAPCOM described it as a birthday present to Luca.  :D

Excellent. Thanks for keeping track on that side of things!

New thread within the hour for the business end of berthing.
