Russian Spacewalk 58 will be conducted by Sergei Prokofiev,
EV 1, in the red stripes and Dmitri Patelin, EV 2, in the blue stripes.
To start the spacewalk, crew will egress the Poisk airlock,
turn on the helmet video and lights and begin translation to the radiator
on the Nauka module using Strela 1, a telescopic pole
that can be used as a crane to move crew and equipment around.
After arriving at the worksite, the pair will work together
to release a couple restraints, then fully deploy the radiator.
Sergei will
then translate Nader to the Coolant Fluid Servicer.
Dmitri will have a shorter translation to a nearby radiator interface panel.
Sergei and Dmitry will coordinate with each other and Moscow
Mission Control to manipulate the necessary manual valves
and begin the transfer of coolant to the new radiator.
While the radiator completes the coolant transfer, Dmitri will join
Sergei at the European Robotic Arm or ERA end effector number two.
They'll work
together to outfit ERA with a gap spanner using a temporary handrail
that allows translation to the boom segment.
After retrieving the temporary handrail,
crew will translate to ERA end effector number one
where they'll repeat the process to install a second
gap spanner.
Dmitri will then translate back Zenith to the Radiator Interface
Panel.
The team will repeat the coordination from earlier to ensure the coolant
fluid servicer has filled the radiator
sufficiently.
Once complete, they'll translate back to the Poisk
airlock via Strela 1,
where they'll perform a tool inventory, inspect each other suits,
ingress and close the hatch ending Russian Spacewalk 58.
