Protective cover removed from interface. No FOD. Also a nice helmet cam view of Soyuz MS-23.

The @ESA robotic arm, operated by cosmonaut Andrey Fedyaev inside the station, moves the radiator from the Rassvet module to the Nauka module during today's spacewalk. nasa.gov/live

Cosmonauts have finished setting up Nauka's attachment point for the radiator. Fedyaev will now start final maneuvering of the ERA to get it to integration position.

Unsure what to do with the MLI cover that served to protect the attachment point. Devising how to secure it or otherwise take it out of the way so that it won't interfere with the installation.

Mating radiator cables to Nauka's patch panel and temp-tying them to a nearby handrail in order to have then handy when the installation takes place, and then complete the electrical connection.

Loosening screws in order to detach the protective cover over Nauka's attachment point.

Moving the radiator to 1.5 m standoff

Standoff distance 0.5 m now.

Cosmonauts giving their in-situ nod to go ahead and move it to the final 15-cm hold point. Alignment looks fine half a meter away.

Checking final alignment, no corrections needed, getting ready to perform the mate.

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.
