free Good afternoon from Space six headquarters in Hawthorne, California It is July the fifth, just after 7 30 PM at our Florida launch site.

Space X team is preparing for launch of the Falcon nine carrying Intel set 35 e in just under seven minutes from historic Launch Complex.

39 a launches scheduled this evening at 23 hours 38 minutes.

Universal time or 7:38 p.m. Eastern Daylight Saving time.

I'm John is Broker Falcon nine principal integration engineer, and I'll be bringing you updates and commentary during today's Webcast.

Now the good news is the Falcon 19 working.

No issues were just a little bit more than six minutes to go.

Liquid oxygen loading is continuing on both the first and second stages.

Feel loading is completed on both stages.

We're currently chewing in the nine Merlin Merlin engines on the first stage.

The software does a series of checks to make sure Falcon nine is good to fly, as you've heard about in our last two launch attempts.

Now, on Monday during the second launch attempt, a first stage measurement in the avionics system did not match the pre program limit in the ground date of its, so the ground software halted the launch space.

X engineers have confirmed the rocket was good and there were no changes required to the flight Hardware way have modified the limit for today's countdown to avoid a possible repeat off the abort space.

Six teams also spent the Fourth of July conducting an additional review of both the rocket and ground systems.

And today we're looking good for launch in just over five minutes from now.

Now you may notice the Falcon nine on the launch pad.

You can see the Goths clouds coming off of the vehicle in the close up of the first stage.

The first stage is expendable on this flight.

We won't be covering a return to a drone ship or the launch site instead will be focusing on the second stage flight as we go into first a parking orbit with Intel set 35 unending to the final Geo stationary transfer orbit.

Speaking of Intel, sent 35 the spacecraft team has gone on internal power.

Everything's looking good on the spacecraft for the range Both the Air Force and Kennedy Space Center are supporting today, they are ready to go the airspace and the sea space is clear.

Working no issues and finally on the weather.

It's great looking whether today loose guys, the sea breezes kept the thunderstorms inland.

So both the ground level winds are looking good.

The upper attitude winds and clouds are also excellent for launch Now, coming up on T minus four minutes coming up and counting down.

The strong bank will recline that slightly away from the Falcon nine.

We move it a degree and 1/2 away, back and then we will see it Move the rest of the way at lift off.

Another major activity you're going to hear t minus one minute is the call out of flight computers and start up.

The ground computers air in automated control of the vehicle.

They'll do the last checks, including those t minus 12th checks like the engines make sure we're at full power, and then the Falcon nine will be commanding the ground system to release it and away we go.

So we're gonna listen with the rest of you in the last 3.5 minutes as we count down Falcon nine carrying Intel set 35 e to geosynchronous Geo stationary transfer.

And it's digital locks closed out stage to your term.

Falcon on his own internal power Embody fueling complete vehicles and cell phone ground.

F T s announce A of t s is ready for launch.

Verify up nine and start up Falcon nine's and start up Stage one.

20 Docket nines configured for flight to minus 54 three two four Stays with you, Howard T plus 50 seconds into flight.

You heard the call out on countdown net one avionics is nominal.

Earlier, we heard propulsion call out a nominal call for the nine Merlin one day engines.

Next, major activity coming up in just over 50 seconds of maximum dynamic pressure after nine currently has gone supersonic vehicles experiencing back down in a pressure plus one minute, 30 seconds into flight we've heard to call out.

The vehicle has gone through the period of maximum dynamic pressure.

That's where the velocity of the vehicle and the density of the lower altitude of the Earth's atmosphere combined to create the greatest loads on the Falcon.

The Merlin engines throttle down and then throttle back up to full power in preparation going through this phase.

Continue to head towards stage separation coming up at about two plus 2 46 seconds.

Now there'll be a sequence of activities that happened very rapidly in just about 35 seconds from now, you'll hear Mico main engine cut off.

Nine Merlin First stage engines will shut down for seconds later.

Seven seconds after that, the upper stage engine ignites to propel the second stage and Intelsat into the parking orbit.

Let's watch and listen as we come up on Meeko and stage separation.

You hear the applause in the background Here.

Learn a successful shutdown, state separation and admission of the upper stage engine.

The next major activity coming up in about 20 seconds 25 seconds is faring.

Separation will watch for that is the camera switches to afford view showing Intel set 35 e inside the payload faring bank separation.

More conjecturing coming up on t plus four minutes into flight.

Reviewed it and I saw a successful separation.

The payload faring Intelsat attached at the top of the second stage are exposed to the vacuum of outer space.

Trajectory looks good for the Falcon nine T plus five minutes into flight.

Propulsion on the second stage engine continues to look good.

Everything going well on the flight of Falcon nine carrying intel set 35 is a reminder for recoverable first stage flights.

We typically might have seen the boost back burn.

We'd be getting ready for the entry burn on this mission.

So we're not following the first stage we're going to stay with.

The second stage is it powers its way into orbit with shutdown of the upper stage engine plant at about T plus eight minutes and 40 seconds.

That will be the 1st 1st shutdown of the upper stage engine.

There is a second burn plan later on is where you pass over.

Africa will be bringing that to you and we'll talk about that a little bit later.
