Russian spacewalk 56 will be conducted by Sergei Prokopyev,
EV1 in the red stripes and Dmitri Petelin, EV2 in the blue stripes.
Anna Kikina will assist a suit IV
and European robotic arm-ERA- operator.
To start the spacewalk, crew will egress the Poisk airlock with a tool carrier,
crew lock bag and an adapter to assist with ERA operations.
After securing the adapter on the Strela 1 translation ring,
crew will translate to the port side of the Poisk module.
Here, they will retrieve the ERA adapter.
Sergei and Dmitri will move along the Strela 2 boom and continue
Nader to the Rassvet module.
Dmitri will temporarily stow the ERA adapter on a nearby
handrail.
Crew will move further Nader to the radiator worksite
where they'll first work to disconnect a radiator cable, cap
it and set it aside.
Nearby, the two will remove a protective cover from the radiator, close
the fluid connectors, then remove the protective cover.
Each crew member will open a Nader radiator
launch lock, then translate zenith to release two more
launch locks.
While the ERAgrapples onto the radiator,
Dmitri and Sergei will monitor the robotic motion.
Once motion is complete, they'll close MLI flaps over
the launch locks.
The team will retrieve the previously stowed ERA adapter
and install it on the Strella adapter.
Sergei removes the protective cover
and further configures the ERA adapter booms.
Both crew will begin a long translation zenith
to the Zaria module,
translate aft
along Stella 2 to Poisk, then continue on to Strella 1
down to the Nauka module where they’ll arrive
at the next worksite.
Dmitri and Sergei will work
together to make three connections on a cable, inspect screws
and remove a protective cover from the interface.
Crew will
move to a monitoring position and provide a go to Anna
to maneuver the radiator in for mating to the Nauka module.
After mating the radiator,
both crew will perform final mechanical, hydraulic
and electrical connections.
From there, they'll translate back up Strela 1 to the Poisk airlock.
Sergei will secure a jettison bundle to Strela 1
and after performing a tool inventory, Sergei
and Dmitri will ingress the airlock and close the hatch.
Ending Russian Spacewalk 56.
