satellites they are rising thanks they are pushing for strong backing to be retracted our sterling satellites are taking off from Pad 4e at Vandenberg Space Force Base, California, the teams are currently tracking smoothly and weather conditions are looking good.

The firing range is also green and ready to support takeoff in approximately four and a half minutes from now and in preparation for takeoff, as you just heard in a few moments. It makes us preparing for the retraction. You can see that the retaining arms are now opening just below the fairings. We started loading propellants about 30 minutes ago. At this time, the Falcon 9's first stage and second stage are still charging their liquid oxygen or locking up the vehicle. is fully charged with all of its rp1 or liquid kerosene and as you can see there, that strong back is retracting, we expect the first stage to conclude its lox charge in t minus 3 minutes, so in just under 30 seconds the stage one blocks the charge. complete, as you just heard, the first stage has completed, uh, the charging of the liquid oxygen, the second stage will finish the charging of its locks in less than a minute from now, as I mentioned, the vehicle is already fully charged with its rocket-grade kerosene or rp1, approximately 30 seconds until Charging the second stage locks is complete, the second stage and with that Falcon 9 is now fully loaded with one million pounds of fuel and liquid oxygen, this

mission

marks the seventh flight of the booster you see on screen, having previously supported the Michael Froelich Dart Sentinel and four Starlinks. missions as a reminder today's mission is for starlink and we will send it online we will send another 46 satellites to low earth orbit. ld is ready for launch t minus 30 seconds 15 seconds minus 10 9 8 7 6 5 4 3 2 1 again stage one propulsion is nominal power and nominal telemetry.

The falcon is now supersonic, as you just heard, falcon 9 is traveling faster than the speed of sound max q and you hear that falcon 9 has reached max q the maximum dynamic pressure the vehicle will feel. During the flight, the mvac engine cooling has started, we are less than a minute until the separation of the main engine cut-off stage and the start of the second engine, we just heard the call that the mvac cooling has started, the vehicle is flowing some of that super cold liquid oxygen into the turbo. pumps on the second stage engine in preparation for ignition, main engine cut-off stage separation confirmed and rear ignition bearing separation confirmed and there you can see that those fairings have deployed and the grille fins have also been deployed They just deployed there in the first stage on the left.

The side of your screen today marks the third flight for both halves of the fairing and we will attempt to recover them once they fall to earth with the help of our recovery vessel NRC Quest, the western coast of California which has just fallen out of sight on the side left of your screen with those city lights in the background, as you can see in the telemetry at the bottom of your screen, the first stage is still a nominal trajectory, the first stage is still increasing in altitude just a little, so which even though it has already separated from the second stage, it still has a little bit of upward travel left before reaching its peak or apogee and at that moment it will begin to return to Earth to land on our unmanned ship, of course.

I still love you as a reminder, today's payload is for Spacex's Starlink satellite internet constellation. We can now see in the telemetry at the bottom left of the screen that that first stage is now returning to Earth, which we are about 30 seconds away from. burnt input on the first stage, everything continues to look nominal with the first and second stage, the stage one has saved the stage one at the start of your friend, as you can see there, the stage one has fired three engines to reduce the speed to atmospheric re-entry to this burn. should last about 20 seconds, we have restarted two of the radial engines and the center engine, as you just saw, which concluded that Falcon 9 is using its onboard computers to autonomously guide itself back or down to the ship no crew that is stationed in the pacific ocean a couple hundred miles off the coast of california we are less than a minute away from landing first stage burn transonic stage 1 as you just heard stage 1 travels near the speed of sound stage two feet has saved stage one The lighting turns on there, you can see that stage one has fired an engine, the center engine is preparing to land on our drone ship.

You can begin to see in the background here stage one letting the light unfold. Stage one landing is confirmed, all good and as you can see there. Falcon 9 has landed on this marked 58th Spacex first stage landing on our drone ship of course I still love you and our 39th launch this year closed out the nominal orbit insertion and as you just heard we had a good second engine shutdown as well as a good orbit right now stage two is now carrying 46 starlink satellites into low earth orbit with that ceco1 confirmation we will conclude tonight's webcast be sure to check spacex social media to confirm deployment from starlink as always thanks for watching and we will see you again very soon
