SpaceX launched 22 Starlink satellites from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Base in Florida.
The first stage for the rocket landed on the A Shortfall of Gravitas droneship in the Atlantic Ocean shortly after separation.

00:00 T-10, 9, 8, 7, 6, 5, 4, 3, 2, 1, engine full power, and liftoff of Starlink. Go Falcon, go Starlink.
00:18 Stage 1 propulsion is nominal.
00:28 [engine noise]
00:41 At T-plus 30 seconds, F9 has successfully lifted off from SLC-40 at Cape Canaveral, Florida, at 12.01 a.m. Eastern Time.
00:51 A major milestone coming up is Max Q, which is when the vehicle experiences the greatest amount of external stress as it ascends through the Earth's atmosphere.
00:58 [engine noise]
01:12 Vehicle is supersonic.
01:14 Just heard that Falcon 9 is supersonic, which means it is now traveling faster than the speed of sound.
01:20 [engine noise]
01:22 Max Q.
01:24 There you just heard that call-out from Max Q, which again is when the rocket experiences the largest amount of external stress.
01:31 [engine noise]
01:41 We're now about one minute away from a series of key back-to-back events.
01:46 MECO, or Main Engine Cut-Off, stage separation, SES-1, or Second Engine Start-1, and then fairing separation.
01:51 MECO, or Main Engine Cut-Off, is when all nine of the Merlin engines on the first stage shut down.
01:57 Stage separation is when the first and second stages separate from one another.
02:01 SES-1, or Second Engine Start-1, is where we light the Merlin vacuum engine on the second stage, and then it's followed by fairing separation,
02:08 which is when the two fairing halves separate and fall away from the second stage.
02:13 So let's keep an eye out for those events, as they're going to happen pretty quickly back-to-back.
02:16 [engine noise]
02:41 Main Engine Cut-Off.
02:43 Stage separation confirmed.
02:47 [engine noise]
02:50 MVAC ignition.
02:53 So as you just saw and heard over the nets, we had successful MECO, stage separation, and SES-1.
03:00 We're coming up on fairing separation from the second stage in just a few seconds.
03:05 [engine noise]
03:09 You can see two of the grid fins on the left-hand side of your screen. Those are deploying on stage one.
03:15 [engine noise]
03:21 Fairing separation confirmed.
03:24 Both of the fairing halves that supported today's mission are flying for the second time,
03:30 and we'll be attempting to recover both fairing halves using our recovery vessel, Bob.
03:36 [engine noise]
04:01 So we'll have intermittent views of stage one, but we do have a great view of stage two.
04:05 So currently the first stage is on its way back to Earth towards our drone ship, a shortfall of Gravitas,
04:11 and that MVAC engine that's attached to the second stage is continuing its burn, which will last another few minutes.
04:18 [engine noise]
04:36 Acquisition of signal, Bermuda.
04:39 [engine noise]
04:44 Nominal trajectory.
04:47 [engine noise]
05:00 Designed and manufactured by SpaceX, Starlink is the world's largest satellite internet constellation.
05:06 Starlink satellites operate in low Earth orbit, or LEO, which enables the delivery of high-speed,
05:12 low-latency internet to people living in remote and rural locations around the globe.
05:16 Starlink is currently live in 62 countries and 78 markets around the world.
05:21 [no audio]
05:42 As mentioned earlier, today's Starlink mission marks SpaceX's 50th mission just this year and 249th mission overall.
05:48 Coming up next in the mission is the entry burn on the first stage,
05:52 which is the first of two burns it'll go through in preparation for landing.
05:57 [no audio]
06:25 Stage one entry burn startup.
06:26 Stage one FTS is safe.
06:28 There's that call out for stage one entry burn.
06:32 The booster has reignited engines one, five, and nine to help it slow down for atmospheric re-entry.
06:39 [no audio]
06:43 Stage one entry burn shutdown.
06:46 And there you just saw and heard that call out that entry burn on the first stage has now completed.
06:51 [no audio]
06:54 Stage two FTS is safe.
06:55 [no audio]
07:23 If you take a look at the bottom left hand side of your screen, you can see that stage one is continuing to slow down,
07:29 whereas on the right hand side, you can see that stage two continues to increase speed.
07:34 [no audio]
07:40 Stage one transonic.
07:42 There's that call out that the first stage is transonic, which means it's traveling near the speed of sound.
07:50 [no audio]
07:54 Coming up in a few seconds will be the landing burn on stage one before it touches down on our drone ship, a shortfall of Gravitas.
08:03 [no audio]
08:14 Stage one landing burn.
08:17 Expected loss of signal, Cape J6 and PPF.
08:20 [no audio]
08:29 Stage one landing light deploy.
08:31 [no audio]
08:40 Stage one landing burn.
08:43 This Falcon 9 first stage has now successfully launched and landed for its 15th time.
08:48 Now we're coming up on second engine cutoff in a couple of seconds.
08:52 [no audio]
08:54 And vac shutdown.
08:56 [no audio]
09:00 And there you just heard we had Seiko 1, and now we are waiting for confirmation of good orbit.
09:07 [no audio]
09:36 [no audio]
09:45 [no audio]
09:47 There's that call out we were waiting for, confirmation of good orbit.
09:51 Today's landing marks our 210th overall landing of an orbital class rocket, including Falcon 9 and Falcon Heavy missions.
09:59 And with confirmation of successful first stage landing and second engine cutoff, that wraps up our coverage for now.
10:05 Be sure to check out our social media for confirmation of Starlink deployment.
10:08 Thanks for watching and we'll see you next time.
