00:00 >> Josh, question for you.

00:02 For the rules, we are go with center line camera only.

00:07 Is the crew okay with that?

00:10 >> Yeah, I affirm.

00:15 >> Copy.

00:23 [ Silence ]

00:51 >> You can see a view of the Dragon spacecraft as it closes

00:55 in on the space station, and it's just about 22 meters away,

00:59 so it's really close to reaching that waypoint 2 spot.

01:02 >> Houston, at waypoint 2, Dragon will hold

01:04 for a few minutes, and we'll let you know

01:07 when we're ready to resume approach.

01:09 >> Okay, station copies, and we see it coming up on 20 meters now.

01:16 [ Silence ]

01:23 >> Vehicle has reached waypoint 2, and it's going to pause here

01:27 for a few moments before it closes

01:29 in for contact and capture.

01:30 This is just to make sure everything is still good

01:33 on the Dragon side and the space station side before we close

01:37 in and complete the docking operations.

01:39 [ Silence ]

01:56 >> Just before docking, you'll hear the call chop,

01:59 which is crew hands off point, and this basically tells the crew

02:02 not to send any commands at that point.

02:08 >> And station, we see hold.

02:10 >> Copy that.

02:13 >> You just heard confirmation

02:18 that the vehicle is currently holding

02:20 at that waypoint 2 position, and this is the final stop,

02:24 just 20 meters in front of the space station.

02:26 [ Silence ]

02:51 >> Dragon is on final approach and is go for docking.

02:56 Monitor for steps 5 and 6 in 1.102.

03:00 >> Copy, go for docking and docks 5 and 6.

03:10 >> Good copy, and for Satoshi,

03:13 he can abort his monitoring activity.

03:16 MLM looks good.

03:17 >> Satoshi copies.

03:23 >> You just heard that we have a go to finish docking.

03:31 It'll begin its final approach.

03:34 During the capture and contact, the capture ring

03:41 on Dragon will interact with the international docking adapter

03:44 on the node 2 forward point port of station

03:47 to get the initial capture.

03:48 Dragon's two sets of 12 hooks, or 12 total hooks,

03:52 will then engage for a hard capture.

03:54 Once we have that hard capture, there will be a vacuum-tight

03:57 seal between Dragon and the station,

03:58 which is called the vestibule.

04:00 This will then be pressurized to match the same pressure

04:04 as station, and then once pressurized,

04:06 the crew will be able to open the hatches

04:08 and begin operations later today to unload the cargo.

04:10 There will also be a couple of umbilicals deployed to get power

04:13 and data from station to Dragon, which will move Dragon

04:16 into what's known as the acquiescent mode,

04:18 essentially becoming an integrated piece

04:20 of station once it's docked.

04:21 Dragon is now within 16 meters of station and closing in.

04:28 Houston, from station, range is 15 meters.

04:41 Attitude looks good, and it's in the corridor.

04:44 Houston copies.

05:39 Dragon is now about 10 meters away from the space station.

05:42 Station, 10 meters.

05:44 Corridor looks good.

05:45 Attitude looks good.

05:46 Houston copies.

06:07 [ Silence ]

06:34 The vehicle is now about five meters away

06:37 from the space station, and shortly,

06:39 you will hear the call chop.

06:41 Five meters.

06:42 Same report.

06:43 Just crew hands off point.

06:45 [ Silence ]

07:57 [ Silence ]

08:00 Copy.

08:01 Just heard confirmation of soft capture

08:05 at 4 o 7 a.m. Central time, 5 o 7 a.m. Eastern time

08:09 over Central Brazil.

08:10 During the soft capture phase, the capture ring

08:17 on Dragon is interacting

08:18 with the international docking adapter on the Node 2 forward

08:21 port of station to get that initial capture.

08:23 Dragon's 12 hooks will then engage for a hard capture.

08:29 Ring retraction in progress.

08:32 Copy.
