A SpaceX Dragon spacecraft carrying the Axiom Space Ax-4 crew undocked from the International Space Station.
See footage shortly after undocking when signal was re-acquired by mission control from the ISS.

"Ax-4 is commanded by former NASA astronaut Peggy Whitson, who is currently Axiom's director of human spaceflight. She's joined on the mission by pilot Shubhanshu Shukla and mission specialists Sławosz Uznański-Wiśniewski and Tibor Kapu," according to Space.com.

00:01Dragon, SpaceX, on the big loop, depart burn 1 complete and nominal.
00:06You are go to DOF suits per procedure 4.012.
00:14Nominal departure and 4.012 for Dragon.
00:26And we just had confirmation there that that second departure burn known as depart burn
00:311 has completed and it was executed as expected.
00:36The crew is now going to start doffing or removing their space suits and getting settled
00:42in for their 22 and a half hour journey back to Earth again with that splashdown targeted
00:46for tomorrow morning, July 15th off the coast of California.
00:55And as a reminder, just like during its approach to the International Space Station, Dragon's
00:59departure and deorbit is designed to be fully autonomous, requiring no action from the crew
01:03on board.
01:04However, unlike Dragon's arrival, there are no hold points during the departure sequence,
01:09therefore it takes a lot less time to leave the vicinity of the space station than to arrive.
01:13So we just had confirmation of that second departure burn being completed and that is the second
01:20in a series of four.
01:21However, it's the only one that was left within the vicinity of the space station.
01:26The next departure burn will take place about 45 minutes from now after Dragon is well on
01:31its way back to Earth and outside of the approach ellipsoid.
01:43Dragon is now about 195 meters away from the International Space Station and should be crossing the keep-out
01:55sphere momentarily.
02:06And we just heard confirmation that Dragon has exited the keep-out sphere.
02:10Again, the keep-out sphere is an invisible 200-meter line centered on the space station.
02:15It's one of several safety zones set up to govern spacecraft arriving and departing from the International Space Station.
02:22While spacecraft are inside the keep-out sphere, they have to be configured where they would not cross
02:26into the imaginary boundary for at least four orbits, even if the spacecraft lost all maneuvering.
02:33The next major milestone for Dragon's departure will be exiting the approach ellipsoid.
02:37This is planned to take place about 13 minutes from now.
02:41Dragon, Station, Houston, on the big loop.
02:43Dragon has exited the keep-out sphere.
02:50Dragon copies.
02:52Station copies.
02:59Station looks beautiful.
03:01Station looks beautiful.
03:12Text on screen.
03:12As simple as 뜨isye.
03:13Sam, you can also see your new LiL Act equals leg.
03:18And we'll read those entirely.
03:18Say thank you for yourımark.
03:18Sempre ahead and at the end of those.
03:18Take this 권esso zien Scott.
03:20The next one is the eighth respect.
03:24of your water is the same group.
03:30The next one is ango- pasta.
03:31It appears this is an intimate
03:31There, too.
03:31What is the provision in the shape that sleeps is an intuitive app?
03:31There might not be a loop.
03:41So now that Dragon has exited the Keepout Sphere, the next major milestone for Dragon
03:46is crossing the Keep, or the Approach Ellipsoid.
03:49That will take place a little over 10 minutes from now.
03:52The Approach Ellipsoid is another imaginary shape, similar to the Keepout Sphere, but
03:57this time it's a three-dimensional ellipsoid measuring 4 kilometers by 2 kilometers by
04:012 kilometers.
04:02And one of the key differences with the Approach Ellipsoid is that vehicles outside of it have
04:06to be on what we call a 24-hour safe free drift trajectory.
04:10This means the spacecraft would not cross into the Approach Ellipsoid for at least 24 hours,
04:14even if it lost all maneuvering.
04:16After the spacecraft crosses the Approach Ellipsoid, joint operations will end and responsibility
04:21for the spacecraft will be handed back to the SpaceX flight control team in Hawthorne, California.
04:26Again, everything continuing to look good with Dragon's departure today following a physical
04:31separation about 10 minutes ago at 6.15 a.m. Central, 7.15 a.m. Eastern.
04:41Dragon is now about 340 meters away from the International Space Station and continuing to increase that
04:47distance.
04:47And teams on the ground will continue to monitor the weather ahead of a splashdown tomorrow,
04:53Tuesday, July 15th at 5.31 a.m. Eastern off the coast of California.
04:59After Dragon exits the Approach Ellipsoid, there will be a couple of more departure burns and
05:03phasing burns to set the spacecraft up for the correct phasing and location for splashdown.
05:09And for those of you who are just joining us, the SpaceX Dragon spacecraft carrying the Axiom
05:15Mission 4 crew recently undocked from the International Space Station's Harmony Module at 6.15 a.m. Central,
05:207.15 a.m. Eastern to complete an 18-day stay aboard the orbiting laboratory.
05:25Station Houston on the Big Loop. Johnny, please give Huntsville a call on Space to Ground 4.
05:44Dragon lifted off atop a Falcon 9 rocket on Wednesday, June 25th from Launch Complex 39A
05:50at NASA's Kennedy Space Center in Florida and docked to the space-facing port of the International
05:54Space Station's Harmony Module after a 28-hour journey on Thursday, June 26th.
06:00During their stay aboard the International Space Station, the Axiom Mission 4 crew conducted
06:05more than 60 experiments, and they will now be returning to Earth with more than 580 pounds
06:11of science and hardware.
06:12This was the fourth private astronaut mission to the International Space Station enabled
06:17by NASA.
06:19And while Dragon and the Axiom Mission 4 crew continued their departure from station, and as
06:23we stand by for the Approach Ellipsoid exit in just under 10 minutes from now, let's go
06:28ahead and check back in with Jesse and John in Hawthorne.
06:33Thanks, Anna.
06:34And we've got some great live views here.
06:37Previously, we didn't have any live views because we had a loss of signal, which is normal as
06:42we are passing by several ground stations.
06:45We're now passing over a ground station where we do have acquisition of signal and getting
06:50these great live views.
06:51Also, in your bottom right-hand corner, you can follow along with this new graphic and
06:56see the thrusters firing on Dragon on the forward bulkhead, as well as the telemetry in the bottom
07:01left-hand corner.
07:03Now, as we mentioned earlier, Dragon is fully autonomous, which means it's capable of flying
07:08itself.
07:08Dragon was designed from the beginning for flying humans to space, even though its first missions
07:13carried only cargo.
07:14Now, before we could fly humans, our teams implemented a number of design upgrades to make sure that
07:19both Dragon and Falcon 9 are suitable for flying people, and then put both vehicles through
07:24thousands of tests to prove their safety.
07:26Now, prior to the Axiom Mission 4, SpaceX successfully completed 52 flights of Dragon to and from orbit
07:33since 2010, including 47 trips to the International Space Station.
07:38AX-4 is SpaceX's 18th human spaceflight mission.
07:42And before Axiom Mission 4, SpaceX had flown 66 crew members, meaning that this mission brings
07:48that count to 70.
07:50That's incredible.
07:52You know, missions like this are important milestones for everyone involved, from the
07:55crew members who fly, to those that they represent, and to the host of scientists and engineers
07:59around the world who have an opportunity for their research or their technology to be tested
08:03in microgravity.
08:05Everyone learns from these missions.
08:06And for Axiom Space, this is at the heart of why we do these missions.
08:09We are building opportunities for others to advance what is possible and expand what is
08:13known.
08:13We want to enable every human everywhere to take part in this.
08:17Now, after a beautiful launch on June 25th, the AX-4 crew docked with the International Space
08:22Station a little over a day later, opening the hatch and greeting the Expedition 73 crew
08:26on June 26th.
08:28The crew shared some good words and a welcoming ceremony before quickly getting to work on their
08:31extensive itinerary.
08:33Now, each crew member brought with them a host of research, technology demonstrations,
08:37and outreach objectives, ranging from human physiology to space radiation impact studies,
08:43and even some gardening.
08:44Now, this crew maintained a very full timeline, but they prepared for this.
08:48Each crew member wanted to ensure that every minute of this mission was utilized well and
08:54that all objectives were hit.
08:55So, Peggy, Shooks, Suave, and Tibor were ready to work.
09:00Now, over the course of 18 days on board the station, they accomplished over 60 research
09:04activities as well as more than 20 outreach events.
09:07And as our time on station came to a close, the AX-4 crew participated in a brief farewell
09:11ceremony where they said their goodbyes to the Expedition 73 crew.
09:16Now, for more details on the incredible work performed by this crew on orbit, check out axiomspace.com.
09:24Now, at this time, the crew is getting closer to reaching the approach ellipsoid.
09:30So, let's head back to Ana at Johnson Space Center to step through these next moments.
09:35How's it going, Ana?
09:39Thanks, Jessie and John, and thank you for that update.
09:41We are continuing to stand by for Dragon to exit the approach ellipsoid.
09:47We are expecting that exit to take place about three minutes from now around 6.34 a.m.
09:53Central, 7.34 a.m. Eastern.
09:59Dragon is currently about 700 meters away from the International Space Station following
10:04a physical separation about 16 minutes ago at 6.15 a.m.
10:09Central, 7.15 a.m. Eastern.
10:16The approach ellipsoid is one of several safety zones set up to govern spacecraft arriving and
10:21departing from the International Space Station, similar to the keep-out sphere which Dragon
10:26exited about 10 minutes ago at 6.21 a.m. Central, 7.21 a.m. Eastern.
10:32But unlike the keep-out sphere, which is an invisible 200-meter line centered on the
10:37Space Station, the approach ellipsoid is a three-dimensional ellipsoid measuring 4 km by 2 km by 2 km.
10:44When a spacecraft is outside the approach ellipsoid, they have to be on what we call a 24-hour
10:50safe free drift trajectory.
10:53This means the spacecraft would not cross into the approach ellipsoid for at least 24 hours
10:57again, even if it lost all maneuvering.
10:59It affects theor� violently.
