EVA RFG Retrieve 2.5.
EV 1 in red stripes egresses first
with a crew lock bag,
followed by EV2 in white stripes.
EV1 translates to the external stowage
platform to install the bag, while Ev2
translates over the platform
to the forward face
of crew work
to release several quarter turn fasteners
on the multi-layer insulation tent
over the radio frequency group.
EV1 moves
underneath the platform
to remove the covering.
Then EV1 visually inspects
the radio frequency group and relocates
the tool bag.
Meanwhile, EV2
takes a portable foot restraint
and installs it onto the robotic arm.
Ev2 Ingresses the foot restraint
in the arm, moves to the next worksite.
The crew will work together
to remove rubber
applied to the bolts
on the aft, switch clamps.
Then, using a
ratchet wrench
and a specially designed wrench,
they will release the tension
in the five clamps,
keeping the radio
frequency group onto the stanchion.
EV2 will return to the forward
face of the stowage platform,
then release four structural bolts
using the Pistol Grip tool.
Next, Ev2
will slide the radio
frequency group from the mounting plate.
Then the arm will fly EV2 over
to the airlock.
Meanwhile,
EV1 will translate to the airlock.
After opening the thermal cover,
EV1 will retrieve
the microorganisms carry
and stowed externally on a handrail.
If you two will reorient the radio
frequency group
and the two crew will stow it
inside the airlock.
Afterwards, EV1
will close the thermal cover.
Both crew will return
to the external stowage platform
to secure the multi-layer
insulation covering over the stanchion.
EV1.
We'll go back to the airlock is Ev2
retrieves the tool bag
EV1.
Puts the microorganism
handle in carry
on their mini workstation.
Then EV1 translates under US laboratory
to the vacuum exhaust system.
Stand.
The first sample will be in open space,
the second will be a swab of the vent
surface.
EV1 will then
translate to the laboratory's
carbon dioxide
vent to sample that location.
Next, EV1 will return to the airlock
to swab samples at various locations
around the airlock hatch.
While
EV1 performs the microorganism sampling,
Ev2 will go to the zenith, or topside,
of the External Stowage Platform
Ev2 or remove the multi-layer insulation
covering a spare robotic arm joint
Ev2 release three of six fasteners
using the Pistol Grip tool.
Then Ev2 will drive the joints
motor approximately six degrees.
This prepares the joint
if it's needed on a subsequent
contingency EVA.
After recovering the joint,
Ev2 takes the crew lock
bag back to the airlock, where Ev2
will replace some tethers in the bag.
That completes the plan test
for this Eva.
