Luca parmitano Andrew Morgan will once
again be going out on a Messi VA this
will be e VA number three in the repair
sequence this is the VA with a new AMS
pump system will be brought out of the
airlock and installed on AMS itself the
pump system is rather large and cannot
be transported by a single crew member
therefore both crew work together
handing off the pump system one to the
other as they inch worm their way from
the airlock all the way to the forward
side of the external support platform
number two
the canadarm2 or SSRMS will meet the
crew there at what point drew will take
control of the pump system while Luca
ingresses the articulating portable foot
restraint on the SSRMS
once in the photo strange Luca will take
the pump system and prepare for the
flight of the canadarm2 from ESP to all
the way over top of the trust AMS in a
similar manage of the trajectories he's
taken on EVs 1 & 2 well he's riding the
Canada arm to drill we'll translate and
of her hand across the truss and up to
ELC - with bags to prepare the work site
to meet Luca therefore the installation
of the pump system drew will provide
eyes on to assist Luca and aligning the
system and install it on to AMS into the
mechanical attachment device
once there the crew will use the pistol
grip tool to PGT to connect the bolts as
well as connecting the power and data
cables securing the new pump system to
AMS and allowing the heaters to be
activated
once the system has been powered on
it'll be prepared for the fluid
connections which Luca will do from a
different work site on AMS the SSRMS
will carry him from the zenith side to
the aft side here and he slides in to
get ready for those fluid connections
[Music]
there'll be six flu connections
completed here at this VSP worksite
using commercial off-the-shelf wages
thus wages have been encased in a custom
fitting that the engineering team to
develop to allow the astronauts
pressurized gloves to operate the small
Farrell's of the swage
once those six wages are completed the
SSRMS will take Luca to the underside of
AMS for two finals wages drew will have
to pass the tubes from the new pump
system down through a passageway in AMS
to allow Luca to connect those on the
nadir side here
while that NATO worksite Luka will have
to be mindful of several hazards to AMS
and tight clearances while he sweeches
those tubes
[Music]
once complete with the eighths wages
this will allow the engineering teams to
pressurize the system and with the crew
support complete for the day Luca will
ride the assignments back to the forward
side at VSP - and prepare for our
airlock ingress well Lucas riding the
arm drill will be translating back and
starting to bring bags back inside I've
been left out on the ELC over the course
of the e V a series and with both crew
back at the airlock that'll complete EBA
