Just found the following graphic showing the RS configuration plans:

Notice it shows one Progress and a Soyuz docked to the Node Module.

Also note that graphic I posted in my previous post shows the Docking Compartment-1 (Pirs) attached to the aft port of the SM. Maybe the Russians plan on recertifying and keeping Pirs (if the module is still in good working condition).

I'm pretty sure that's the experiment airlock (currently attached to MRM-1 and not yet assembled), and NOT Pirs.

Looking closer at that graphic, it looks like they labeled the SM as DC, so this is not Pirs, but the airlock you mentioned is clearly seen attached to the MLM. I wonder if they made a mistake by showing two Russian VV attached to the Node Module, or if this was the plan originally, or if this could still be in the plans somehow by upgrading either the docking ports on the Node Module or upgrading the docking system on Soyuz/Progress?

An image of the Node Module transported by the Progress-M tug. Note that this variant drops the cylindrical unit attached to the front of the Node that was seen on the Commercial Space Station.

From the 2010 Energia Annual Report.

What's the status of when/if this launches?

Not only is it ugly… but the side thruster clusters have been moved…

AFAIK, there never have been side thruster clusters on the Node Module, these are electrical hydraulic refueling valves, similar to the units on Pirs.

It has been formally approved and will launch in 2012 (likely to be 2013 now).

If you are referring to the mid thrusters on the Progress-M tug, there is no way that those have been moved or changed; that would be a really, really big deal if it happened. The location and position of those thrusters create constraints that are reflected in the design of the Node Module itself.

Well, not according to the link, which specifies that the Node Module design has been approved within Energia, but is silent on the issue of Roskosmos approval.

The 2010 Energia report is also silent on the issue of either a launch date or Roskosmos approval.

I am sure that the weird looking thrusters in the drawing are just an artifact. The engineering drawings show standard Progress M thrusters.

 But what about the forward facing thrusters?

From Energia's engineering drawing of the Commercial Space Station, you can see that the Progress thrusters are normal.

Orbitaltechnologies has a lot of internal views of their space station online:

Don't think they are "borrowing" all this from the node module for ISS...

I don't read Russian, so may be someone can answer. But I've read that Roscosmos is planning to replace all their current Soyuz with Soyuz-2.1a/b by 2014 (I guess that's at the factory side, probably 2016 at the launch site). Is there any mention of the custom Progress LV? It would be a good step to see what it takes to adapt current Progress and Soyuz capsules to the new LV.

The structure is definitely the same, the internal layout for the Commercial Space Station is their own fantasy.

Where did you read that rather amazing news?
