00:00 Falcon nine is in startup.

00:02 And there's that call out.

00:04 The internal flight computers have now taken over the launch countdown.

00:08 Now we're just waiting for the final call from the launch director.

00:12 Starlink 69, go for launch.

00:19 And great news. All systems are go for launch.

00:23 So let's watch as Falcon 9 takes our 22 Starlink satellites into space.

00:29 T minus 30 seconds.

00:32 T minus 15 seconds.

00:47 T minus 10, 9, 8, 7, 6, 5, 4, 3, 2, 1.

00:57 Ignition and liftoff.

01:00 Go Falcon. Go Starlink.

01:03 Vehicle is pitching downrange.

01:11 Stage one propulsion is nominal.

01:15 Stage one propulsion is nominal.

01:17 At T plus 35 seconds into flight, Falcon 9 has successfully lifted off from Space Launch Complex 40 from Cape Canaveral, Florida,

01:43 at 117 a.m. Eastern time.

01:45 Nominal power and telemetry.

01:47 Now we are throttling down the engines in preparation for max Q, which is coming up here in about 20 seconds.

01:55 That is the largest amount of external stresses that the vehicle will see on ascent.

02:01 Vehicle is supersonic.

02:05 Max Q.

02:14 And there's that call out that we just passed through, that period of maximum dynamic pressure.

02:21 Now we will throttle these engines back up.

02:24 And seeing some great views of Falcon 9 and those nine Merlin engines lit up there on your screen.

02:33 And back engine chill has started.

02:35 And we do have a few events coming up here back to back.

02:42 That will be MECO, stage separation, SES-1, as well as fairing separation.

02:48 MECO is where we will shut down all nine of those engines that you see lit up right there on your screen.

02:54 And that will help slow the vehicle down in preparation for stage separation.

02:59 Stage 1 will begin to make its way back down to Earth, scheduled to land on just read the instructions today.

03:05 And stage 2 will continue with SES-1, which is second stage engine start 1.

03:10 And we will ignite that MVEC engine on the second stage as it carries the payload to its targeted drop-off orbit.

03:18 And then shortly after, we will have fairing separation.

03:22 And those events are coming up here in just a few seconds.

03:28 Main engine cutoff.

03:30 Stage separation confirmed.

03:34 MVEC ignition.

03:40 And great views there on your screen.

03:46 We just had MECO stage separation.

03:49 And you can see on your right-hand screen that the MVEC engine has ignited.

03:53 The grid fins on your left-hand screen, the grid fins on the first stage are currently deploying.

03:59 Fairing separation confirmed.

04:04 And there you can see on your right-hand screen, those fairing halves deployed from the second stage.

04:11 They're now returning back to Earth.

04:13 And the fairing halves supporting today's mission have flown on previous missions,

04:18 with one flying for its 10th time and the other for its 11th flight.

04:23 We'll be attempting to recover both fairing halves using our recovery vessel, Doug.

04:44 Now what you're seeing on your screen, on the right-hand screen, is a view of the second stage looking at our MVEC engine.

04:50 And on your left-hand screen is a view...

04:53 ...is a view from on Earth looking at the second stage MVEC engine.

05:10 Designed and manufactured by SpaceX, Starlink is the world's largest satellite Internet constellation.

05:25 Starlink satellites operate in low Earth orbit,

05:28 which enables the delivery of high-speed, low-latency Internet to people living in remote and rural locations around the globe.

05:34 [no audio]

05:37 [no audio]

06:04 As I mentioned previously, today's Starlink mission marks SpaceX's 55th mission just this year, and 254th mission overall.

06:13 Now coming up on the first stage vehicle will be the entry burn.

06:19 That's the first of two burns that will help it prepare for landing today.

06:24 And you're not seeing stage one on your screen, but you are seeing a view of the MVEC engine on the second stage.

06:31 [acquisition of signal, Bermuda]

06:34 Now entry burn is where we will reignite three of the nine M1D engines on the first stage vehicle,

06:46 and that helps slow the vehicle down in preparation for re-entering the Earth's atmosphere.

06:51 After the entry burn concludes,

06:56 the atmosphere will actually help scrub most of the velocity on the vehicle until we start up the landing burn.

07:03 Stage one FTSO is safe.

07:11 Stage one entry burn start up.

07:15 And there you can see on your left-hand screen a view of the first stage and the engines reigniting on the vehicle.

07:23 This is the entry burn that lasts about 20 seconds long.

07:27 Stage one entry burn shutdown.

07:33 Stage two FTSO safe.

07:38 As you can see those engines shut down on your screen.

07:42 The entry burn is now complete.

07:44 Again, the atmosphere will help scrub most of the velocity on the first stage vehicle,

07:49 and then we will ignite just a single E9 engine in preparation for landing,

07:55 which is powerful enough to slow down the vehicle to touchdown on -- just read the instructions tonight.

08:02 Nominal trajectory.

08:05 And that landing burn is coming up here in about a minute.

08:09 Shortly after the vehicle is scheduled to land,

08:17 we will also have SECO one, or second engine cutoff one.

08:21 So you may hear those callouts very closely to each other.

08:27 Stage one transonic.

08:32 And you just heard that callout that stage one is transonic.

08:43 That means that the vehicle is traveling near the speed of sound.

08:47 Again, the landing burn is coming up here in about 15 seconds or so.

08:52 Stage one landing burn.

09:04 And there you can see on your screen that the landing burn has begun.

09:08 So let's watch as Falcon 9 prepares to touchdown on -- just read the instructions.

09:14 Landing leg deploy.

09:19 Stage one landing confirmed.

09:27 And as you just saw that Falcon 9 has touchdown on our drone ship.

09:33 Just read the instructions.

09:35 [ Silence ]

09:43 And vac shutdown.

09:45 [ Silence ]

09:51 And we just had SECO one.

09:53 [ Silence ]

09:59 Stage one on everyone.

10:01 Nominal orbit insertion.

10:03 [ Silence ]

10:05 And there's that callout for good orbit.

10:08 Today's landing marks our 216th overall landing of an orbital class rocket,

10:14 including Falcon 9 and Falcon Heavy missions.

10:17 And with confirmation of successful first stage landing and second engine cutoff,

10:22 that wraps up our coverage for now.

10:24 Be sure to check our social media for confirmation of Starlink deployment.

10:28 Thanks for watching, and we will see you next time.
