The crew will be starting out on the first of the AMS repair EVAs. Here we've got
Luca Parmitano is EV1 and Drew Morgan is EV2. Luca is here picking up the whiff
extender to install on the end of the Canadarm2, while Drew is breaking out
some tool bags stowing them on the outside the airlock and also bringing
something with him to translate up the truss as well. Here Luca proceeding up
to meet the Canadarm2 where he will start to configuring that for the
starters for pair series. So here's Drew will pass by Luca, head all the way out
to AMS to the Express Logistics Carrier to where he will start setting out bags.
Drew will make several trips between the airlock and the Express Logistics
Carrier in order to bring all the tools for the repairs out to the work site and
have them staged and ready for what Luca's arrival with SSRMS. So here Luca
will be setting up the WIF Extender followed by the Articulating Portable
Foot Restraint which will give him to reach necessary to perform the repairs
on AMS since there are no handrails currently installed on that payload for
repair activities.
Once Luca has his tool bag and is on the end of the SSRMS he will fly a sweeping
range of motion that will take him well over top of the ISS where he will get a
great view of the space station and they will take lots of video and photos that
we can use to keep an eye on the state of station. The arm will stretched out and
wrapped around the AMS there will be several places of tight clearances, the
arm operators will have to negotiate for Luca is at the aft and outboard work
site here. You can see him flying up over top of the truss where the arm will wrap
around the backside of AMS and push him in between AMS and the ELC in order to
reach the worksite to repair AMS is thermal pump system. Once Luca is at that
work site, he'll be removing a debris shield working with Drew that to access
the primary work area of AMS repair. Here they're installing a handling aid
that'll be used to handle this debris shield after its removed. They're about a
dozen non captive fasters that'll be removed in order to release this debris
shield, several will be under these capture cages and they'll be trapped
that way and several will be released using capture forks to be put into a
separate capture block so that they are managed and not released.
Once all the fasteners release from the debris shield Luca will hand it off to
Drew who will be in his own foot restraint and he will face aft on the
ISS and jettison that debris shield. Due to its large size it is not easy to put
that back at the airlock so jettison is the optimum choice for that shield.
Once the debris shield has been removed and jettisoned, Luca and Drew will work
together to install other hand rails. Here we've installed that the first
three handrails the dido beam handrail, then Drew will hand over two more
handrails that the crew will install that they are the vacuum case handrails this
will allow Luca and Drew better access and mobility at the worksite preparation
for the second through fourth EVA of the series. Following the handrail
installation crews will close up their tool bags and make their way back to the
airlock here Luca is on the end of the arm and will repeat his translation on
the end of the arm back to the front of trust. While he's flying on the arm
Drew will translate around the outside of the ELC and translate back under the
mobile transporter back to the airlock for the end of the first of the AMS
repair EVA's.
