EVA Movie
The DOUG flight file was not available publicly (2nd occurrence).
I have followed up with the PAO on whether or not it is the new standard policy to not publicly share the DOUG flight files for Russian EVA
VR Lab got back to me and stated that there was "pushback" from "EVA stakeholders" on posting the DOUG file publicly. I have submitted a FOIA about the relevant details.






Nauka commissioning threads meta commentary
My rational for removing of # elapsed spacewalks and total # of spacewalks for Nauka commissioning from the title are:

1. Our current numbering scheme on the forum is incorrect.

VKD-49 - 1/10
...
VKD-53 - 5/10

We lost sync on the following threads (with myself inadvertently contributing to the error)
(This has been fixed)

VKD-ESA RS EVA (5/10 Nauka&ERA ops): 21 July 2022 [Artemyev, Cristoforetti] - This should have been 6/10 (Corrected)
VKD-54 RS EVA (6/10 Nauka outfitting): August 17, 2022 [Artemyev, Matveev] - This should have been 7/10 (Corrected)
VKD-54A RS EVA (7/1? Nauka outfitting): September 2, 2022 [Artemyev, Matveev] - This should have been 8/11. (Corrected)
VKD-55 RS EVA (8/13? Nauka outfitting): Nov 17, 2022 [Prokopiev, Petelin?] - This should have been 9/13. (Corrected)

2. The original estimate of 10-11 spacewalks is no longer valid. The most recent thread had listed 13 total spacewalks. However, the linked source for the increase in the total spacewalks stated 14-15 total spacewalks to complete commissioning.

I feel that tracking progress via N of X number of spacewalks is not the most representative picture of the evolving commissioning process.

According to NASA TV:

No spacewalk today, Prokopyev's suit had a problem with a backup pump.

No information yet about a new date.

Rob Navias said ventilation pump, not cooling.

Today’s spacewalk is cancelled due to an issue with one of the spacesuits. The #EuropeanRoboticArm, almost fully stretched, autonomously grappled a large radiator earlier is now going back to its home position on the #Nauka module.

Having started a number of those threads, I have corrected the OP titles as you indicated - thanks for checking it!

However, I feel the initial estimate of 11 was reasonably stable throughout the process so far: VKD-ESA and VKD-54A were not considered in the initial planning, so adding those to the sequence yields 13. Anatoly Zak lists 15 taking into account an additional preparatory one (VKD-48, which we did not count as "Nauka outfitting" because Nauka wasn't there yet :) ) . I believe the final source of disagreement between the two lists was due to the radiator taking up two EVAs at the beginning of the series, but now takes three - not sure whether the timelines were refined since then, some unexpected issues forced dividing up a single EVA into two, or something else.

So yeah, I agree it's probably not so worthwhile to keep track of Nauka's full commissioning with an (N/X) designator on each VKD, but we can also easily consider the current EVA to be the 10th in a series of 14, taking into account all revolve around a single objective.

Spacesuits repaired, and the #EuropeanRoboticArm is ready to work again outside the @Space_Station installing a large radiator on the #Nauka module. 👨‍🚀🔧🦾🛰️
The radiator mission will start on Wednesday 14 December (22h CET) and run the whole night until the morning (10h CET).

Quote
Can the #EuropeanRoboticArm operate in full sunlight? Yes, it can! 🤖😎
🤓 Fun fact: the whole spacewalk and radiator mission will take place for 12 hours with no orbital nights. This is because the International @Space_Station is in a high beta angle until 18 December.

Last week, the cosmonauts on board of the ISS repaired the pumps in the cooling system of one of #OrlanMKS spacesuits (and, according to the rumors, replaced the pumps in the second one). The next attempt to perform #VKD56 will be on December 15, 02:20 - 09:20 UTC.

Busy bees for the #EuropeanRoboticArm 🦾
Two spacewalkers will work tonight with @esa's space robot to install a radiator on the #Nauka module.
The night will be long: the robot will start moving around the @Space_Station at 22h CET. Spacewalk coverage begins at 3 am on @NASA TV.

A third crew member, Anna Kikina, will operate the #EuropeanRoboticArm from inside the International @Space_Station.

#DYK that the radiator mission happens during the high beta angle season? That means no orbital nights on the Space Station during the spacewalk.

Cosmonauts Getting Ready for Spacewalk Live on NASA TV

NASA Television coverage is underway for today’s spacewalk with Roscosmos cosmonauts Sergey Prokopyev and Dmitri Petelin. The duo, with assistance from European robotic arm operator cosmonaut Andrey Fedyaev, will relocate a radiator from the Rassvet module to the Nauka science module on the International Space Station Coverage of the spacewalk is on NASA Television the NASA app, and agency’s website.

Prokopyev and Petelin will exit out of the Poisk module at about 9:30 p.m. EDT Prokopyev is wearing the Orlan spacesuit with red stripes, while Petelin is wearing the suit with blue stripes. This is the fourth spacewalk in Prokopyev’s career, and the second for Petelin. It is the third spacewalk at the station in 2023 and the 260th spacewalk for space station assembly, maintenance, and upgrades.

Final alignments complete, standing by to complete the mating until after an upcoming Ku LoS. Meanwhile, for the next 15-20 min, they'll reconfigure some foot restraints.

While we wait, it's interesting to note there are some sensors (STRs?) with a high-rpm moving part, probably a mirror, exposed and operating next to the moving spacewalkers and their gear. MCC-M did note they should avoid touching a sensor, presumably this one, which was next to their worksite - but it seems really easy for something to slip off a few centimeters and contact it. Not sure how delicate or necessary that sensor is once the radiator is in place, but it seems turning it off would regardless have been a reasonable step to take before so much action was due to take place around it...  ::)
Also, when taking the screenshot I just noticed they did touch the radiator and sent it wobbling during this pause, and obviously the instruction was not to touch it to keep the alignment intact.  ;D

Unsurprisingly performing a final alignment again. Now receiving visual assessment from the spacewalkers, turning to manual ERA mode as opposed to the prestored choreography used until now.

The exit hatch is closed!
Roscosmos cosmonauts Sergei Prokopyev and Dmitry Petelin spent 7 hours and 55 minutes overboard the ISS.

During the release:

▪️ the radiator on the Rassvet module was prepared for transfer;
▪️ with the help of the ERA manipulator, the radiator was transferred to the "Science" module;
▪️ an adapter for the ERA manipulator was installed on the airlock chamber at Rassvet;
▪️ the radiator was docked to Nauka;
▪️ An "Anchor" platform has been installed to fix the legs during the exit.

Thank you for being with us! Stay tuned!

👨‍🚀 Russian crew members have started printing mock-ups of the ISS modules on a 3D printer in order to conduct spacewalk training, our special correspondent, Roscosmos cosmonaut Dmitry Petelin reports.

Before practice, pilots sometimes work out a flight mission on the ground "on foot in flight" when they walk along the runway, imitating the trajectory and relative position of their aircraft with their models or palms. In the future, the astronauts plan to assemble a model of the entire station.
