01:41 So coming up in about 45 seconds, we'll have several events in quick succession.
01:55 The first of those will be MECO or main engine cutoff.
01:59 That's where all of those Merlin 1D engines will shut down on the first stage.
02:03 Then we'll have the stage separation.
02:05 The first stage or the booster is going to do a flip maneuver.
02:08 While that's happening, the second stage is going to ignite its Merlin vacuum engine.
02:14 And then the first stage is going to start its boost back burn to go towards landing
02:18 zone 1 to attempt that land landing.
02:20 So MECO stage separation, the flip maneuver, second engine start, and then boost back burn.
02:31 Main engine cutoff.
02:34 Stage separation confirmed.
02:42 And back ignition.
02:45 Stage 1 boost back startup.
02:50 Awesome views on the lower right there.
02:52 That was the second stage heading off to orbit.
02:55 We've got a tracking shot here of the first stage doing its boost back burn.
03:05 This tracking view from the ground looking back at this first stage.
03:08 Again, its 14th flight today, so we're looking for its 14th landing attempt at landing zone
03:13 number 1.
03:21 And this is a view from the cameras on board the first stage.
03:24 We're looking at a shot down towards the engines.
03:28 You can see the grid fins here.
03:29 Those will deploy shortly after the boost back burn completes.
03:41 And a reminder, the second stage is continuing on its mission, but at the request of our
03:46 customer we won't be showing any second stage views today.
03:49 So we're just going to keep focused on the great views we have of the first stage.
04:06 So what you're seeing here periodically are some white gas coming out of the first stage.
04:12 On the right-hand box on your screen are the grid fins deploying.
04:15 We use the aerodynamic grid fins to get the first stage back towards our landing site.
04:22 The aerodynamic control of the vehicle once we get into the Earth's atmosphere.
04:34 Those white plumes that you're seeing are of an attitude control gas.
04:38 We use -- those are referred to as cold gas thrusters.
04:43 So we have some gas stored on the vehicle.
04:47 And since there isn't very much atmospheric force this high up in the atmosphere, we have
04:51 to give ourselves little puffs of thrust to orient the vehicle, get the heat shield pointed
04:57 down and get the vehicle in the entry attitude to come back towards landing zone one.
05:22 Great shots of planet Earth.
05:32 Again the camera on the right-hand side of your screen now is actually looking up through
05:36 the interstage.
05:37 So we're looking into that carbon fiber interstage.
05:41 That's where the second stage was previously.
05:44 And on the left-hand side of your screen we've got a ground tracking shot of the first stage
05:47 making its way back towards landing zone one, not too far from the launch site at Kennedy
05:54 Space Center.
05:55 Now we're
06:20 coming up on the entry burn for the first stage.
06:26 So there are two burns that we do here.
06:29 There's an entry burn where we turn on just a few of Falcon 9's engines.
06:33 That's to slow down as we start getting back towards the atmosphere and start to pick up
06:37 some heating on the vehicle.
06:40 And then the second of those burns is much closer to landing.
06:43 >> Entry burn start up.
06:45 >> So here's the first of those burns, the entry burn.
06:49 First burn lasting just about 20 or so seconds.
07:06 >> Stage one entry burn shutdown.
07:08 >> Stage one FTSO safe.
07:13 >> And there is successful shutdown of the entry burn.
07:18 So now the next major burn will be the landing burn.
07:21 That'll happen just before landing.
07:24 We'll ignite just a single Merlin engine.
07:28 The landing legs will deploy and then hopefully we'll have a soft touchdown at landing zone
07:32 one.
07:33 You can see it starting to come into focus here on the view on the right-hand side of
07:38 your screen heading towards landing zone one.
07:43 >> Stage one transonic.
07:58 >> Stage one landing burn.
08:02 >> Stage two FTSO safe.
08:06 >> And there is the startup of the single center Merlin engine for landing burn.
08:10 We'll see the grid, excuse me, the landing legs deploy here.
08:22 >> Stage one landing leg deploy.
08:29 >> And there is successful landing of our first stage.
08:34 That marks for the 14th landing on this particular booster, 294th landing of an orbital class
08:40 rocket.
08:41 We also heard a call out there for nominal orbit insertion cutoff and then nominal orbit
08:48 insertion.
08:49 So that means the second stage is well on its way for the rest of our mission.
08:53 But with our first stage landed, that's going to bring our webcast coverage to a close for
