[NOISE] As you just saw, Falcon Nine has successfully cleared the pad.
It's now on its ascent, with test space craft on its fairing.
Coming up in about 15 minutes, your going to hear the call out that Falcon 9 would have hit max q that stands for maximum aerodynamic pressure.
That is the point at which the rocket is seeing its highest stress.
On its descent.
[BLANK_AUDIO]
Vehicle has passed maximum air dynamic pressure.
You can tell by the cheers and what you heard on that call out, we have gotten through max Q. Coming up next, you're gonna hear the [UNKNOWN] [CROSSTALK]
Has begun.
And that was it.
That was where we chill in that Merlin backing engine back to
To operating temperature.

Now coming up here shortly you're gonna hear three big events happening in rapid succession.
The first is MECO, that stands for main engine cut off, that is where all nine of the first eight engines are gonna shut down That's in preparation for the next step, which is stage sep or stage separation.
[INAUDIBLE] stage one, we'll separate from stage two.
Stage one will make its way back down to the drone ship.
Stage two will continue on with test to its orbit.
And then, you're going to hear second engine start.
That is the ignition of the second stage Engine, let's check it out here.

All right, and as you just saw we had a successful stage separation and a successful ignition of that second stage engine.
Stage one has transpired.

to H-1 is Transanta Group, about 10 seconds away from that landing burn.
Note that the drone shape is situated approximately 300 kilometers off the coast of Florida, and [INAUDIBLE] [APPLAUSE]
Let's see if we can catch it.
