00:00 [ Silence ]

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.
