Probably they will take a look at the Progress only during the next planned EVA. When the next one? Because the port has to be cleared for the ATV in June...
Next EVA is on June 26 - and M-19M will undock prior to that.
So no inspection required if all things continue to go right. Or after the Progress departure and before the ATV arrival.

Are we close to shift handover in MCC Houston? Seems to be a lot of people in the control room.
Handover time today is at 1300z in MCC-H
Thanks. That explains it.

As per NK forum, the docking has been completed in "backup automatic mode".
Sounds like this antenna needs to be gotten rid of

Right, thanks to all that joined in. Keep an eye on things as I've got to rush off and do some day job work to pay the bills.
Who's stupid idea was it to start a website that costs so much to run?!

Looks like Russian MCC team went to celebrate
"It was one of the hardest days on ISS program for me and others. But we made it!"
Well done!

It would be great to get an explanation of how Kurs operated in this "backup automatic mode". The system isn't known for being a robust software environment, where patches and upgrades can be easily implemented. In fact, AFAIK, Kurs is an analog system (I confess to being ignorant of the computer type), based on observation of the insides of a Kurs active box.
The other question is whether the pyro bolt that "unhinges" the lateral Kurs active antenna was fired during the last stages of docking, and whether this freed the antenna.

According to the pictures posted on this thread, it is clear that 2ASF1-M-VKA-03 was still retracted at the moment of docking.

I've been away for an hour. Did the pressure check pass?

I have not heard anything yet to believe not, but I heard crew being told on ISS Mission Audio that MCC-M is continuing to review data and make final assessments and a decision is expected on whether or not to delay hatch opening is to be sent by next DPC or in a radiogram to crew.
It was mentioned earlier that MCC-M would perform prop transfers to RS earlier in the event that hatch opening is not possible once final decision is made.

IMHO When two antennas (ASF1 and ASF2), these antennas operate with different axes (the first port-starboard and other top-bottom). When we have a single antenna ASF it switches the mode control on both axes.

According to the pictures posted on this thread, it is clear that 2ASF1-M-VKA-03 was still retracted at the moment of docking.
The photos in this thread don't show the Progress antennas more than 20 or 30 meters closer from ISS. The lateral antenna pyro is blown about that point, since TsUP needs the antenna to work for most of the closing in process.
There should have been a comment from TsUP about the pyro bolt blowing (or not), since that is a normal operation during docking.
I should note that during nominal dockings with SM Aft, there is no technical requirement to retract the Kurs antenna, but the pyro bolt is blown anyway (there are no obstructions at SM Aft, the obstructions were at FGB Nadir, but those are no longer an issue after Rassvet was installed). This pyro bolt blowing is an artifact from when FGB Nadir was used, and it has not been removed from the programming for consistency's sake.

I do not understand how Kurs can provide range, rate and location data with only one functional ASF antenna. It's kind of like trying to get distance perception with only one working eye.

And the hatch is open - no odors or debris.

Whew!! That was interesting.
Congrats to the Russian teams, they certainly earned their months pay this week.
Time to celebrate - the vodka must flow!

Unless they can figure that out from close-out photos, build documentation, telemetry and such, I don't see how they can do it. As far as I know, they aren't going to go out and take a look, and they certainly aren't getting the part back on the ground, so what else is there?
