The second set of hooks are continuing

0:03

to drive open.

0:04

>> Copy that or sorry, station, copy.

0:05

Dragon's committed to undock.

0:16

>> We're about a minute and a half away

0:18

from the expected physical separation.

0:36

And we have confirmation that the Dragon

0:38

spacecraft has undocked from the

0:39

International Space Station at 11:25

0:42

a.m. Central, 12:25 p.m. Eastern.

0:44

>> Starboard open.

0:47

>> As the space station was traveling 260

0:49

miles over the North Pacific.

0:52

>> Dragon separation confirmed.

1:02

>> And you just heard that call up there

1:03

from the Capcom or capsule communicator.

1:05

>> Good separation.

1:07

>> Capcom is here on the ground at Mission

1:08

Control Houston and serves as the voice

1:10

link between the crew and the ground.

1:33

>> Station, Houston, Dragon departure burn

1:34

zero complete.

1:40

>> And we do have confirmation that that

1:41

first departure burn was completed.

1:51

That was a 17-second burn in the first

1:53

of four departure burns, which helped to

1:55

move Dragon further away from the

1:56

International Space Station.

2:04

With that undocking confirmed at 11:25

2:06

a.m. Central, 12:25 p.m. Eastern, the

2:09

space station was traveling 260 mi over

2:12

the North Pacific.

2:36

If you're just now joining us, we're

2:38

live from the International Space

2:39

Station flight control room here in

2:41

Mission Control Houston.

2:45

Providing coverage for the undocking of

2:46

SpaceX's 34th commercial resupply

2:48

services mission for NASA.

2:54

Good views here of the Dragon cargo

2:55

spacecraft, which separated from the

2:57

International Space Station at 11:25

2:59

a.m. Central, 12:25 p.m. Eastern.

3:06

Dragon is now maneuvering toward the

3:08

exiting the keep-out sphere and

3:09

eventually the approach ellipsoid.

4:27

>> The next burn will be in under 2 minutes

4:29

around 11:30 a.m. Central, 12:30 p.m.

4:32

Eastern.

4:36

That burn will last about 23 seconds and

4:38

will help move the spacecraft beyond the

4:40

keep-out sphere.

5:14

Some really great views here from the

5:16

departing SpaceX Dragon spacecraft.

5:31

There on the bottom is the forward port

5:32

of the station's Harmony module.

5:37

And we're about 30 seconds away from

5:39

departure burn one, which will last

5:40

about 23 seconds.

6:16

>> And we just received confirmation that

6:18

depart burn one is taking place, which

6:20

will last about 23 seconds.

6:30

Now the Dragon cargo spacecraft is

6:32

moving through that key valve sphere and

6:33

again, that's the first of two safety

6:35

boundaries.

6:44

Depart burn one is complete and was

6:46

nominal.

7:01

Good views of the International Space

7:02

Station here.

7:05

>> Station here Houston, departure burn one

7:08

is complete.

7:10

>> On the bottom of your screen, you can

7:12

see the

7:23

On the bottom of your screen, you can

7:25

see the docking port that Dragon just

7:28

undocked from and then at the top just

7:30

above that docking port is the SpaceX

7:34

NASA SpaceX Crew 12 vehicle named

7:37

Freedom that delivered the Crew 12 crew

7:40

back in February of this year.

8:00

>> Station Houston, Dragon has exited the

8:02

keep out sphere.

8:22

>> And we just heard that Dragon has exited

8:24

the keep out sphere and here's a good

8:26

visual on your screen of the keep out

8:28

sphere and approach ellipsoid. These are

8:29

two imaginary safety boundaries around

8:32

the space station. They require go, no

8:34

go poles in the unlikely event that

8:35

something goes wrong with an approaching

8:37

or departing spacecraft.

8:42

The first is called the keep out sphere

8:43

which we just heard the call that Dragon

8:45

has exited and think of it like the

8:47

neighborhood of the space station.

8:50

It extends 200 m away from the orbiting

8:52

laboratory and once Dragon passes

8:54

through that keep out sphere which it

8:56

just did, it'll then travel out and pass

8:58

what is called the approach ellipsoid

9:00

which will ultimately set the Dragon

9:01

cargo spacecraft up on its journey back

9:03

to Earth on a 24 hour safe free drift

9:05

trajectory.

9:15

Once Dragon exits that approach

9:16

ellipsoid, NASA will be out of joint

9:18

operations with SpaceX and their mission

9:20

control team in Hawthorne, California.

9:25

The SpaceX team will continue to monitor

9:27

the rest of Dragon's autonomous flight

9:29

through splashdown.

9:53

>> The next burn that Dragon will undergo

9:54

is depart burn two.

9:57

Which will be about 43 minutes from now.

10:01

At that time we will be out of joint

10:03

operations with SpaceX and we will be

10:05

live for that coverage.

Interactive Summary

This video details the successful undocking and departure of the SpaceX Dragon cargo spacecraft from the International Space Station (ISS) as part of a NASA resupply mission. The coverage follows the spacecraft as it executes initial departure burns to move away from the ISS, safely clears the station's 'keep-out sphere' safety boundary, and prepares for its return journey to Earth.
