RS EVA VKD-57 - Nauka Outfitting (ShK Airlock) - May 3rd [Prokopiev, Petelin]

VKD-57 has been recently reprogrammed for a week later than initially planned in order to "perform a more detailed study of its tasks", according to statements from Roscosmos. It will now take place May 3rd instead of today as previously expected.
The main objective for this EVA is the completion of the relocations of add-on items located on Rassvet since its 2013 launch, following in the footsteps of the Nauka RTOd radiator relocation last week, by transferring the Science Airlock ShK from MIM-1's side (a bit zenith from the former stowage location for the radiator) to MLM's front docking port at its nadir end through the use of ERA. Full activation of the airlock is not expected until later in the spring/summer timeframe (tentatively June) during VKD-59, following operational loading of the radiator in the intervening VKD-58.
One question regarding the specifics of the work is whether the ERA-to-Strela adapter is still to be employed for the relocation (narrower boom between ERA and the airlock in the last attached rendering, see the discussion starting here in MLM's General Thread for more context:
https://forum.nasaspaceflight.com/index.php?topic=23444.msg2369121#msg2369121).

That's a pointless question. The adapter is needed because in itself ERA doesn't have the reach to grab the airlock. If the adapter wasn't needed, the Russians wouldn't have bothered to bring it up onboard MLM in the first place.
Without the adapter, the only way to get the airlock from MRM to MLM is by hand, tugged by the cosmonauts via extending a regular STRELA boom between MRM and MLM.

Not sure why the aggressive antagonism is warranted. The Strela solution you mention was thoroughly and well-explained in the linked thread, at the time of the issues with ERA commissioning. However, the user that introduced the extension boom topic mentioned he was unsure whether it was still the main solution or it might have been canceled in favor of another approach, to which no conclusive answer was given, prompting my question today.
There is also another contingency scenario involving SSRMS+SPDM by the way, so Strela and tugging isn't the *only* way, were ERA to not be available.

First rule about Russians: once they have a plan, they almost never change it:
The plan for getting ERA to the ISS hasn't changed since 2012.
The plan how to commission ERA hasn't changed since 2012 (the commissioning of ERA in 2022 followed the commissioning plan from 2012 to the letter).
The plan to use ERA to transfer the radiator from MRM to MLM hasn't changed since 2012. Just a few days ago that plan was executed per that 11 years old plan.
The plan to use ERA to transfer the airlock from MRM to MLM hasn't changed since 2012.
The plan to involve an extension piece for this hasn't changed since 2012. Said extension piece has been in existence since 2010.
The STRELA plan is the backup in case ERA, for whatever reason, would not be available.
The SSRMS plan is the backup of the backup.

MEDIA ADVISORY M23-049
NASA Updates Coverage of Roscosmos Spacewalks at Space Station
Roscosmos cosmonauts Sergey Prokopyev and Dmitri Petelin conduct a six-hour and 25-minute spacewalk in their Orlan spacesuits.
Roscosmos cosmonauts Sergey Prokopyev and Dmitri Petelin conduct a six-hour and 25-minute spacewalk in their Orlan spacesuits to transfer a radiator from the Rassvet module to the Nauka multipurpose laboratory module for future installation. The duo is pictured tethered to the Rassvet module with the Soyuz MS-22 crew ship docked at top.
Credits: NASA
NASA will provide live coverage as two Roscosmos cosmonauts conduct two spacewalks in May outside the International Space Station to relocate hardware from the Rassvet module to the new Nauka multipurpose laboratory module.
Follow each spacewalk on NASA Television, the NASA app, and the agency’s website at:
https://www.nasa.gov/liveDuring the spacewalks, Expedition 69 cosmonauts Sergey Prokopyev and Dmitri Petelin will venture outside the Poisk airlock Wednesday, May 3 and Friday, May 12, to help in transfer and install of an experiment airlock to Nauka and deploy a radiator to provide module cooling. The airlock and the radiator attached to Rassvet were launched on the space shuttle Atlantis STS-132 mission in May 2010. The radiator and the airlock will be robotically transferred by ESA’s (European Space Agency) robotic arm on Nauka with those movements operated by cosmonaut Andrey Fedyaev inside the orbital complex.
The content and coverage times of the spacewalks are (all times EDT):
Wednesday, May 3
3:30 p.m. - NASA TV coverage begins for a spacewalk to move an experiment airlock from Rassvet to Nauka.
Friday, May 12
11:30 a.m. - NASA TV coverage begins for a spacewalk to deploy a radiator on Nauka and connect mechanical, electrical, and hydraulic lines.
The spacewalks will be the fifth and sixth for Prokopyev, who will wear the Orlan spacesuit with the red stripes for all of the spacewalks and the third and fourth for Petelin, who will wear the spacesuit with the blue stripes.

They will have to prepare the airlock for transfer by the ERA manipulator from the Rassvet module and install it on Nauka.
▪️ Opening of the exit hatch - May 3 at 23:05 Moscow time
▪️ The planned duration of the work is 6 hours 22 minutes.

https://twitter.com/katlinegrey/status/1653806273354248215?cxt=HHwWrsC9qeOCwPMtAAAAIn 3 hours, Roscosmos will begin the stream of the next Russian EVA. Sergei Prokopiev and Dmitry Petelin will egress the Poisk module at 21:05 UTC to transfer the airlock from Rassvet module to Nauka. Andrei Fedyaev will operate the ERA manipulator. @VKD57
BTW, Roscosmos announced the delivery of 3 new #OrlanMKS spacesuits to the ISS. One will be manufactured in 2024, and two in 2025. The currently used spacesuits are at the limit of their warranty period, which is 20 EVAs. In No. 4, 17 spacewalks were performed, in No. 5 - 15.
https://twitter.com/katlinegrey/status/1653812579821600772?cxt=HHwWiIC2le7xwvMtAAAAOf course the EVA suits can work beyond warranty, but there are issues already - like the battery power fluctuation Oleg Artemiev faced. Before the new spacesuits arrive, the cosmonauts will have to use Orlan-MKS No 4 and 5, and probably the old Orlan-MK suits stored on the ISS.

Audio of EVA preps is on the ISS Youtube channel . Curious why the Russians have shifted the start of recent EVAs to what is normally the start of the crew sleep period. Edit-translations have started.

Now working on making the necessary electrical connections between Nauka and the airlock - one minor wrinkle, as they discovered that some of the caps had been taped in place.
(Edit - apparently a slightly bigger wrinkle, as they've had to break out the Space Knife. Looks to be a bit less stabby than the one used on the Soyuz MS-09 investigatory EVA.)
