and find out why the antenna didn't deploy in the first place...
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?
Point taken. They should investigate the failure and try to find the cause. Numerous failures are identified without retrieving the offending parts.

It has been mentioned that mission control moscow only had a short span of time every day to download the telemetry and upload patches etc, are they still unable to utilize those two Luch satellites they have launched last year?

Luch-5A and Luch-5B will become operational before the end of the year.

I don't understand why a so long time is necessary for such a satellite to enter operational working mode...
Two spacecrafts are necessary for operation, but from the second launch...

As I understand it, one of the primary concerns was that antennas on the SM of the ISS would be damaged/moved by the out of place antenna on Progress. Is it correct that there is currently no way of knowing if that happened or not? If so, that means we have to wait until undocking to get camera views of the ISS antennas and find out if any damage took place. Am I correct?

I'm more concerned at the moment if we have a complete seal; any leaks yet?

MCC Moscow just gave a GO to open the hatch.

I linked a quoted answer to you above yours.

It has been mentioned many times that two Luch-5 satellites are ready for operation, but there is not equipment for communication with them on ISS Russian segment and on any Russian satellites, because it is not ready.

I think I missed that, but that is just sad!
I only hope that the equipment becomes ready and operational before the Luch satellites reach their end of life!

I don't know much about the Luch satellites so I ask. Can the US side of the ISS use the Luch satellites so information has no dead zones?

I think the US section utilizes the TDRS network.
BTW I must say that I'm rather dumbfounded by anik's answer. What were the Russians thinking when they decided to launch couple of satellites which are just going to sit up there idle because absolutely no one can use them?

When Progress M-19 departs from ISS, it will use its video system to broadcast images of the Service Module docking collar, so we will see if the docking collar has been damaged.
I would bet there may be scuff marks, but I would not expect any actual bent metal.

The risk of bending was actually to the ATV retroreflectors outside the docking collar. The antenna itself was very light material, so if it hit the collar, the no damage should have been done.

If those retro-reflectors were damaged, we will see as Progress backs away.

1. Does the guilty antenna become operational only once fully deployed? Or can it switch on and transmit even when it's retracted in the launch config? If the antenna is highly directional - then we can do a transmit/receive sweep (if we have a frequency compatible, highly directional second antenna on the ISS) and check what orientation of this second antenna gives us the maximum power transfer. Some geometry should be then able to tell you the orientation of the Progress KURS antenna.
2. If the primary concern was not the interference with rings and seals, but contact with the ISS antenna and/or ATV retroreflectors : would you simply be able to rotate the progress along the long-axis by x degrees - before close approach, and dock without issue? I assume the latches and the hooks are all radially symmetrical?
3. It's about time they reprogrammed SPHERES to be used outside the station (provided the hardware is compatible), and set them up with tethers and spools on outermost points. Or sent up something similar. Each retrofitted with a Swiss knife, a duct tape dispenser, and space grade WD-40.

It is pretty sure that the faulty Kurs antenna is still more or less in the undeployed position, although it may have a little range of motion if the pyro bolt blew just before docking.
Either way, that antenna will never be functional again.

You talking about the work done in the last Russian EVA?
