Speaker 1: 7, 6, 5, 4, 3, 2. The vehicle ising down and with the pressures [00:00:30] abdominal power and telemetry,
Speaker 2: Pounds of thrust [00:01:00] headed to space. If throttle down in preparation for Max Q moment of peak mechanical stress on the rocket,
Speaker 1: Falcon heavy is super sonic
Speaker 2: There. We just heard the call out that the vehicle's now traveling faster than the speed of sound, but a beautiful sight.
Speaker 1: Max Q.
Speaker 2: All right there. We just heard the call out. That is the moment of peak mechanical stress on the rocket [00:01:30] M one D engine's throttling. Back up a beautiful site to see Falcon. Have you flying once again shortly we'll hear the call out for m back chill indicating that the second stage is, uh, prepping. The m v engine vehicle
Speaker 1: Is following a nominal trajectory.
Speaker 2: We will flow a little bit of the super chill liquid oxygen through the turbo pumps on that mvac in preparation for the full flow of the super chilled, uh, propellant [00:02:00] shots there of each side booster on the right hand side of your screen. Next event will be booster engine cutoff or beco. That'll be followed by stage separation of side boosters, side booster boost back burn center core main engine cutoff. We are about 10 seconds away from the booster. Um, separation.
Speaker 1: [00:02:30] So side of course booster separation confirmed in the kitchen chair start
Speaker 2: And there you can see and heard it by the incredible excitement within the crowd behind me. Successful separation of the side boosters.
Speaker 1: Booster boosting. Start over
Speaker 2: There. We can see three engines [00:03:00] on each side. Booster have re-lit for their boost back burn at this point in time. Both side boosters are returning.
Speaker 1: Our vehicles are following nominal trajectories.
Speaker 2: Good news there both side boosters and the center core. Uh, everything looking good. Side boosters are returning to the coast of Florida. Uh, now under the power of three engines. That's a view there of the center core coming up. Three events happening in rapid succession will have the conclusion of the side booster [00:03:30] boost back burn, followed by main engine cutoff as well as stage separation of that center core. As a reminder, per request of our customer, we won't be showing uh, second stage views after second engines start one. Additionally, our center core or stage one, the one you see there is expendable today. So we are not recovering. Uh, this booster
Speaker 1: [00:04:00] Who's background shut down Nico State Separation confirmed
Speaker 2: There you the call out and saw on your screen. We had side boost back
Speaker 1: Burn
Speaker 2: Conclusion as well as the main engine cutoff and separation for that center core and we heard [00:04:30] call out of second engine start one. Um, at this point in time, uh, with that callout
Speaker 1: Separation confirmed,
Speaker 2: Uh, we will wrap our coverage pertaining to the second stage, keeping our focus on the side boosters
Speaker 1: Continue to follow nominal
Speaker 2: Trajectory, which you see there unfortunately looks like
Speaker 1: Position of signal from
Speaker 2: Meda. The cameras on those side boosters are a little fogged over. We heard a confirmation of successful faring separation. While second stage continues on its journey, the faring [00:05:00] Hals will fall back to earth where we will attempt to recover them using our recovery vessel. Doug,
Speaker 2: As a reminder, today we'll be attempting to recover the two Falcon heavy side boosters on land. You can sort of make out some cloud coverage there in the background camera. Um, we'll bring that back to you whenever we're able. Now in just a few minutes, the side boosters will execute, uh, an entry burn followed by a landing burn. [00:05:30] Both burns are meant to slow the side boosters down rapidly, uh, before landing at the time of separation. The side boosters were traveling slow enough to turn around and make their way back to land at, uh, at our side by side landing pads. If we have successful landings today, it will mark the 150th and 151st successful landing of an orbital class rocket. As I mentioned earlier, center core, uh, is going to be expended and we are not attempting to [00:06:00] recover it. This allows us to utilize all
Speaker 1: Vehicles, continue to fall in nominal trajectories,
Speaker 2: Allows us to utilize all the propellant on board and deliver uh, peak performance for the payload delivery. On the left hand side of your screen is a live view of Hawthorne Mission Control. Here at SpaceX headquarters, we're about 30 seconds away from the entry burn for the [00:06:30] two side boosters there on the top and bottom of the right hand side of your screen. Standing by for a side booster entry burn
Speaker 1: Booster, Roger Burns have started
Speaker 2: [00:07:00] There. We heard the call out that the booster entry burn has begun.
Speaker 3: Looks
Speaker 2: Like the ice on those cameras are now clearing.
Speaker 1: NY and n y fts have saved all vehicles continue to follow nominal trajectories
Speaker 2: [00:07:30] So that reentry burn has concluded. We're expecting the landing burn to begin in about 30 seconds. The entry burn intended to slow the vehicles down significantly as they reenter the earth's atmosphere. Amazing tracking cam views of the boosters as they return to landing zone one and two. We can see the grid fins there on
Speaker 1: Outside boosters. Transonic stage two fts is saved. [00:08:00] Stage two is internal guidance.
Speaker 2: We can see those grid fins steering the boosters for a precise landing. Again, we're attempting landing, landing, landing zone one and two
Speaker 3: [00:08:30] And there have it. As it indicated about the
Speaker 2: Enormous chairs, we have successfully landed both falconers at landing zone one and landing zone to
Speaker 3: What an incredible site
Speaker 2: With these two side boosters. This marks the 150th and 151st overall successful landing orbital class rocket. This is the 21st landing at landing zone one and [00:09:00] the fourth landing at landing zone two.
