This is the second Radio Frequence Group Retrieval EVA.
EV1 and EV2 egress
the airlock and proceed to the forward face of the truss.
Heading port, the crew put down safety tether ring hooks
and continue outboard of the solar array rotating joint.
EV1 goes to the 2F Left Beta Gimble Assembly
and secures a crew lock bag of tools.
Using the pistol grip tool,
EV1 releases four bolts on each fixture
and then removes it.
EV1 then surveys the worksite.
Meanwhile, EV2 goes to the Solar Array Rotating Joint and removes the cover,
exposing a trundle bearing assembly.
After disconnecting an electrical cable,
EV2 uses the pistol grip tool
to release three bolts and remove the trundle bearing assembly.
EV2 photographs the surface
then applies lubricant to the rotating ring using a grease gun.
Back at the Beta Gimbal Assembly,
EV1 continues a photo and video survey
of the site where an ISS Roll Out Solar Array
modification kit will be installed on a future EVA.
EV1 returns inboard to the Camera Port 8 work site
to adjust a cable interfering with movement of the camera light assembly
After lubricating the surface, EV2 install a new Trundle Bearing Assembly.
EV2 then certifies the worksite.
EV2 surveys the worksite before replacing the cover.
From Camera Port 8, EV1 translates inboard
down the strut and temp-stows the Crew Lock Bag on the US laboratory.
EV1 goes to the airlock, retrieves a different Crew Lock Bag
and takes it to the external storage platform #2.
EV1 retrieves a Portable Foot Restraint
and installs it on the robotic arm.
Then, EV1 ingresses the foot restraint and the robotic arm fli
to the Radio Frequency Group aft position.
EV2 returns along the truss back to the airlock,
stowing the large bag outside the airlock
and joins EV1 on the stowage platform.
The crew work together to fold back the multilayer insulation
surrounding the radio frequency group.
At the aft wedge clamps, the crew will remove any rubber
covering the clamp nets using needle nose pliers.
Then, using a ratchet wrench,
and a specially designed tool, they loosen the five aft wedge clamps.
EV1 is then flown to the forward face of the radio frequency group,
releases four structural bolt,
then removes it from the stanchion.
EV1 then flies it to the airlock, where both crew secure it inside.
Back at the stowage platform, EV1 egresses the arm, removes the foot restraint,
and retrieves the earlier temporarily stowed tool bag.
EV2 secures the covering over the stanchion,
then both crew return to the airlock and ingress.
