01:0030 seconds into flight, Falcon 9 has successfully lifted off from Space Launch Complex 4 East at Vandenberg Space Force
01:06Base.
01:07We're currently throttling down to prepare for Max-Q, which is the point of maximum aerodynamic stresses on the vehicle.
01:14Power and telemetry nominal.
01:16Max-Q is reached when the air density of the atmosphere decreases faster than the increasing speed of the rocket.
01:22Falcon 9 is supersonic.
01:26So now we're just waiting to hear that call-out for Max-Q.
01:35Max-Q.
01:38And there is our call-out.
01:39So Merlin engines are back at full power, and we're out of the throttle bucket.
01:44From here on, even though velocity is rapidly increasing, the atmospheric density is decreasing, resulting in less loads on Falcon
01:529.
01:53And coming up next, we'll have several events happening in quick succession, starting with MECO, followed by stage separation, and
02:01second engine start, or SES-1.
02:06Main engine cutoff, or MECO, is where all nine Merlin 1D engines shut down to slow the vehicle down in
02:14preparation for stage separation, which is where the first stage separates from the second stage.
02:19Then the MBAC engine on the second stage will light, which is called out as second engine start one, or
02:25SES-1.
02:26This engine burn, lasting several minutes, will propel the second stage and our payloads to orbit.
02:33After that, the fairing will jettison from the second stage, as it's no longer needed to protect those payloads once
02:39we're in space.
02:44So we should be hearing the first of these call-outs in just a few moments.
02:58Main engine cutoff.
03:18And there you heard and saw those three events that happened back-to-back, including main engine cutoff, stage separation,
03:25and second engine start one.
03:26Coming up next will be fairing separation.
03:38Fairing separation confirmed.
03:55And there we heard confirmation of fairing separation, along with a great view of those two halves separating from the
04:01vehicle on your screen.
04:02And as a reminder, those fairings will be making their way back to Earth for recovery.
04:08The next major milestone coming up is entry burn on our Falcon 9 first stage, which is scheduled to occur
04:14around the T-plus-6 minute mark.
04:16The entry burn is used to slow the first stage as it heads back towards our drone ship.
04:21Of course, I still love you.
04:26Both vehicles are following nominal trajectories.
04:32We're currently in our first MVAC burn, and this burn should last for another few minutes.
04:37And the next milestone will be the first stage entry burn, coming up in about two minutes.
04:41Now, today, Falcon 9 is performing two burns in order to land.
04:44The first burn...
04:46The first burn...
04:47The first burn...
04:47The first burn...
04:47The first burn...
04:47The first burn...
04:47The first burn...
04:48The first burn...
04:48Gracias.
