00:28 Stage one chamber pressure is nominal.

00:36 [ Radio ]
00:44 At T plus 30 seconds F9 has successfully
00:48 lifted off from slick 40 at the cape at 310 AM
00:52 Eastern Time.
00:56 [ Radio ]
01:00 F9 is currently going through the
01:04 throttle bucket which is when we throttle down the 9 M1D engines in
01:08 preparation for max Q.
01:12 [ Radio ]
01:16 Falcon 9 is supersonic.
01:20 Which means that the vehicle is now traveling faster than the speed of sound.
01:24 Should be hearing the call for max Q shortly. Max Q.
01:28 And there it is. And max Q is the point at which the vehicle
01:32 experiences the greatest amount of external stress as it ascends through the earth's
01:36 atmosphere.

01:48 We're now about one minute
01:52 away from a series of events. MECO, stage sep, SES1,
01:57 and fairing separation. MECO or main engine cut off is where all 9
02:01 of the Merlin engines on the first stage shut down. Stage separation is
02:05 when the first and second stages separate from one another. SES1
02:09 or second engine start one is where we light the
02:13 Merlin vacuum engine on the second stage. And fairing separation is when the
02:17 two fairing halves separate and fall away from the second stage.
02:21 Keep an eye out as these are going to happen pretty quickly back to back.

02:41 MECO.
02:45 Stage separation confirmed.
02:49 Vacuum engine.
02:53 Solid callouts there on MECO, stage separation, and SES1.
02:57 Should be coming up on fairing separation in just a couple seconds.
03:01 Fairing separation confirmed.
03:05 And there you can see those two fairing halves separating and falling
03:09 away from the second stage. Both of the fairing halves that flew on
03:13 today's mission are flight proven with one half flying for the fourth time and
03:17 the other its fifth. We'll be attempting to recover both fairing halves using
03:21 our recovery vessel, Bob.
03:25 Both stages are on nominal trajectories.
03:29 [ Silence ]
03:33 Just as a reminder, on the left hand side of the screen
03:38 is the Falcon 9 first stage and on the right
03:42 is the MVAC engine on our second stage carrying our Starlink satellites to
03:46 their desired orbit.
03:50 [ Silence ]
03:54 [ Silence ]
03:58 [ Silence ]
04:02 The MVAC engine on your screen right there
04:06 is attached to the second stage, is continuing its burn,
04:10 which will last for another couple minutes. And you can read the velocity
04:14 on the bottom right hand side of your screen, which is continuing to increase.

04:46 For those of you who are just joining us, we had an on time lift off
04:50 at 310 AM Eastern time from SLC-40 at Cape Canaveral.
04:54 Today's Starlink mission marks SpaceX's
04:58 39th launch of the year and 230th Falcon 9 mission to date.

05:22 The 52 satellites on today's mission
05:26 will join the rest of our Starlink constellation, which is now delivering
05:30 high speed, low latency internet to over 1.5 million people
05:34 around the globe. Starlink is the world's largest satellite
05:39 constellation and today's launch marks our 20th Starlink mission just for 2023.

06:15 Coming up in a couple of seconds should be the entry burn
06:19 startup on stage one.
06:23 The entry burn slows down the first stage so that all of that heat loading and structural loading
06:27 from the atmosphere doesn't go straight into the vehicle.
06:31 [ Silence ]
06:35 There you can see that entry burn has begun where stage one has
06:39 relit three of its engines, engines one, five, and nine to slow it down for
06:43 atmospheric re-entry.
06:47 [ Silence ]
06:51 [ Silence ]
06:55 [ Silence ]
06:59 You can see that the entry burn on the first stage has now
07:03 been completed. The first stage that is used to launch our 52 Starlink
07:07 satellites into space today is flying for the ninth time today.
07:11 We do have one more burn coming up on the first stage, which is the landing burn
07:15 and it should be coming up in about a minute. The center
07:19 engine, E9 specifically, is the engine that relights for landing burn
07:23 to slow it down before it touches down on the drone ship.

07:48 You heard that the first stage is transonic,
07:52 which means it is traveling near the speed of sound.
07:56 [ Silence ]
08:00 Coming up next, we have the landing burn, which should start
08:04 in about 15 seconds from now.
08:08 [ Silence ]

08:16 Stage one landing burn.
08:20 Stage two terminal guidance. The stage one landing burn has started
08:24 in preparation for a touchdown on our drone ship. Just read the instructions.
08:28 Keep an eye out for the landing legs that are scheduled
08:32 to deploy just a few moments before landing.
08:36 [ Silence ]
08:40 Stage one landing confirmed.
08:44 Falcon 9 has now successfully landed, marking the ninth successful landing for this
08:48 booster. We're now awaiting
08:52 second engine cutoff, which is right on time.

09:00 [ Silence ]
09:04 Nominal orbit insertion.
09:08 And you just heard we had successful
09:12 SECO 1 and nominal orbital insertion. So with
09:17 confirmation of successful first stage landing and second engine cutoff, that's going to
09:21 wrap up our coverage for today. Today's landing marks our 199th
09:25 overall landing of an orbital class rocket, including Falcon 9
09:29 and Falcon Heavy missions, and our 230th Falcon 9 mission
09:33 to date. Be sure to check back for more.
