00:06 >> Stand by one, Woody.
00:07 >> [Inaudible]
00:09 >> Copy. We see it.
00:13 Well done.
00:14 >> And with those restraint bolts released, you can see the solar array begin to unroll.
00:25 It is aided by those magnets that snap together.
00:31 This is the helmet camera view from NASA astronaut Steve Bowen.
00:39 It will take about 12 minutes for the solar array to completely unfurl.
00:47 [ Silence ]
01:08 >> A beautiful view with the Earth below.
01:11 The International Space Station is approaching the coast of Hawaii.
01:17 [ Silence ]
01:35 >> Five magnets on my side are created.
01:38 >> Copy, Steve.
01:42 We see that in your HECA as well.
01:44 Thank you.
01:44 >> NASA astronaut Steve Bowen confirming that he sees those magnets have properly engaged
01:57 with another confirmation from the flight control team here in Houston.
02:01 He is going to remain in that position to keep a good visual
02:06 on the solar array as it rolls out.
02:10 [ Silence ]
02:36 >> About two years from the first IROSA unrolling is the sixth IROSA unrolling.
02:43 Again, that first IROSA or International Space Station rollout solar array was installed
02:51 on June 16th of 2021.
02:55 [ Silence ]
03:02 >> Go.
03:03 >> There's some white rectangles that pop out in the center of IROSA as it's pulling out.
03:14 And it looks like maybe that fifth one up, the right-hand side one, did not fully pop over.
03:22 [ Silence ]
03:33 >> Should be able to see it in my HECA.
03:35 >> Copy, Woody.
03:37 We are getting--
03:38 >> Right out the middle of IROSA.
03:39 >> We are getting eyes on that.
03:41 We appreciate the report.
03:42 Would you be able to get a picture on your camera as well?
03:45 >> Of course.
03:48 >> Thank you.
03:49 [ Silence ]
04:19 [ Silence ]
04:48 >> Woody and Steve, we're about halfway through deploy.
04:50 We'll let you know when we can get moving again after deploy is complete.
04:54 [ Silence ]
04:56 >> Copy, attorney.
04:58 >> After the solar array is deployed, the team will then proceed
05:03 to tension it or make it be pulled tight.
05:07 [ Silence ]
05:26 >> You can see the view here of a size comparison between the new solar array
05:32 with the legacy array, when unrolled, the International Space Station rollout solar array,
05:39 the new one, will be 60 feet long by 20 feet wide.
05:43 And the legacy ones are 112 feet long and 39 feet wide.
05:49 [ Silence ]
05:51 [ Silence ]
06:20 [ Silence ]
06:24 >> To the left is the SSRMS or the Space Station Remote Manipulator System,
06:31 also known as the Canadarm2.
06:33 It is a contribution from the Canadian Space Agency.
06:42 It helps move supplies, equipment, and even astronauts during spacewalks like the one today.
06:50 [ Silence ]
06:59 >> It is over 57 feet long when it is fully extended.

08:48 >> Hi, Woody and Steve.
08:50 We have about two minutes left to deploy, and I have big picture words ready for both of you.
08:55 >> Great. Ready to copy.
08:58 >> Woody, you will be completing the tensioner bolt release,
09:06 and then doing worksite cleanup pretty much as written in the procedure.
09:10 We'll have you get crew lock bag M, and then you'll be translating inboard,
09:14 picking up your green hook along the way, and then working with FFRMS to retrieve the APFR.
09:21 Following that, we'll have more information.
09:23 Steve, you ready?
09:25 >> I'm ready to copy.
09:28 >> Steve, for you, following deploy, you are going to pick up the cable bag and put it on your BRT.
09:36 You'll translate inboard, picking up your green hook on the way, and then we will have you
09:40 at the seat of cart bundling that bag to crew lock bag T.
09:45 >> Understood.
09:49 >> BRT stands for body restraint tether.
09:56 >> We'll have words on get-aheads.
09:58 >> Sounds good.
10:03 [ Silence ]
10:24 >> The sixth International Space Station solar array is completing.
10:30 >> Maybe I didn't notice it on the last deploy, but as we got to the end there,
10:34 I noticed what looked like -- it looked similar to me to what I saw
10:39 when tensioning occurred on the last one.
10:42 [ Silence ]
10:46 >> And it a little popped.
10:48 >> Magnets on your side weren't perfectly lined up before, but they are now.
10:51 [ Silence ]
10:55 >> Copy.
11:00 >> And we think that that pop is normal.
11:03 >> Copy.
11:06 >> Great.
11:08 >> Okay, with that, deploy is complete.
11:13 So well done, both of you.
11:14 Steve, you can translate to retrieve the cable bag.
11:18 And Woody, sudden stops and quick grabs are still not allowed on the mod kit.
11:23 And now you have a 25-foot-pound max lateral load on the mod kit, less than before,
11:29 now that we have deployed.
