might be able to check DOUG and other ISS resources and see about any planning updates et al.
They've actually got about one and a half iROSA mod kits to install, since they only got partway through the 2A mod kit installation on EVA-93. Might require 2 separate EVAs?
Not sure if the one that flew on NG-23 is to have an on-orbit spare, or if a second reflector needs replacing.

12/29/2025On Thursday, Jan. 8, NASA astronauts Mike Fincke and Zena Cardman will exit the station’s Quest airlock to prepare the 2A power channel for future installation of International Space Station Roll-Out Solar Arrays. Once installed, the array will provide additional power for the orbital laboratory, including critical support of its safe and controlled deorbit. This spacewalk will be Cardman’s first and Fincke’s 10th, tying him for the most spacewalks by a NASA astronaut.On Thursday, Jan. 15, two NASA astronauts will replace a high-definition camera on camera port 3, install a new navigational aid for visiting spacecraft, called a planar reflector, on the Harmony module’s forward port, and relocate an early ammonia servicer jumper — a flexible hose assembly that connects parts of a fluid system — along with other jumpers on the station’s S6 and S4 truss.

For 2026The Russians regularly communicate about their program.So, it is known that Kud-Sverchkov and Mikaiev will perform two VKDs during Expedition 75.The first VKD (No. 66) is scheduled for April 2026 to install the Sun-Terhertz experiment and replace the second cassette on Ekran-M.The second VKD (No. 67) is planned for June 2026 to replace the coolant in the Zarya thermal control panel....
On February 17, 2026, Russian members of the main crew of the ISS-75 were trained in the hydraulic laboratory for testing targeted operations of extracurrent activity (VKD-67).The main task that Peter Dubrov and Anna Kikina will have to perform during the spacewalk in real space flight is to replace one of the two panels of the liquid consumption regulator in the thermal mode system of the functional-cargo block (FGB) Zarya of the Russian segment of the ISS.“The panel is small but fueled by a toxic substance for cooling, so it is in a special sealed container that astronauts take out of the hatchet of the gateway compartment and transported to the installation site. The container is not very heavy, but quite bulky.In terms of complexity, this is not the most difficult task, especially in orbit it will be performed for the fourth time. For the first time, the panels were replaced during the VKD-11, the next time - VKD-33, the third time - VKD-48, Peter Dubrova and Anna Kikina will have to perform another replacement. There are two such panels on the outside of the MSK two, and panel No. 1 has already been changed twice, it’s time to change the panel No. 2 for the second time,” said Igor Tarasov, head of the laboratory of the 30 laboratory of the cosmonaut Training Center.In the hydraulic laboratory there is a model of the ERA manipulator, and during training under water, the work of astronauts was accompanied by modeling the location of the robot, which during the spacewalk will help the crew in performing operations.Peter Dubrov and Anna Kikina successfully completed the task assigned to them and showed a high level of interaction. On Thursday, they will again have a training in a hydraulic laboratory, during which the astronauts will also replace the liquid flow regulator panel. But all crossings on the surface of the station and the FGB "Zarya" will be carried out "pawn", without the help of a manipulator, to work out actions if the ERA can not be used for one reason or another.
