Feature article by Chris Gebhardt to mark this rocket's swansong:

The engine replacement is also being carried out on the third stage of the Soyuz-FG rocket, which is used to launch the crewed Soyuz missions to the Station.

It is understood that this engine replacement was made with an 11D55 (RD-0110) engine built in 2016, instead of the previously installed 11D55 engine that was produced in 2014 with the engine that failed on MS-04s launch.

Have any of these suspect engines flown crew already?

TASS reports that the Soyuz-U rocket scheduled for launch tomorrow will carry rocketcams to film the separation of Progress MS-05 from the launch vehicle. The cameras were developed by the Izhevsk Radio Factory. From now on all Soyuz rockets carrying Progress or Soyuz vehicles will be carrying the cameras. Rocketcams were also installed on the first Soyuz rocket to fly from Vostochny last April and will fly on the next five missions from Vostochny. Here is rocketcam footage from the first Vostochny launch :

 
At least one Soyuz rocket that flew from Kourou also carried a rocketcam.


The TASS report does not say whether shots from the rocketcams will be shown live.

possibly yes the only year affected at this time is 2014. Stan Black might have the info on those.

Looking forward to (hopefully) more rocketcam videos.  Sometimes the Russians can be surprisingly open, as the very detailed documentaries about the Angara launch from Plesetsk and some manned Soyuz flights showed.  Excellent Chris G. article, BTW!

What a great article today by Chris Gebhardt. I love it when authors teach me new things! Among a few from this article is this tid bit;
"Once erected on the launch stand, the launch table was rotated to align the Soyuz-U into the proper orientation so that its pitch maneuver will result in the rocket flying on the correct azimuth to orbit.
The veteran Soyuz-U rocket lacks the ability to perform a roll maneuver in flight; thus that element of flight must be accounted for by the launch pad."  Thanks Chris!

Also from Chris's article today, in the third photo from the top what is the item on the outside frame of the third stage at about 5 o'clock? Maybe a electrical hookup with cover?

In simplistic language its one of the cable connection points between stage II and Stage III.

Very hard to get a smooth stream and the aspect ratio is all wrong.
