Welcome to the Webcast of the Falcon nine Mission, carrying the third flight of 10 or idiom.

Next satellites.

You're seeing a live view of Falcon nine as we prepare for launch in just about 15 minutes from now.

Launches currently scheduled for 12 hours, 37 minutes and one second universal time for five hours 37 minutes.

01 second's A M Pacific Daylight Savings Time.

I'm John, his broker, Falcon nine, principal integration engineer, and I'll be bringing you coverage of the Space six launch for the Iridium next satellites during the Webcast.

Now this is our third of eight planned launches for radium.

Our first launch was January of this year.

Follow with the 2nd 1 on June 25th.

Today's mission represents our 15th Falcon nine launch of the year.

Today's launch is from Historic Space Launch Complex for at Vandenberg Air Force Base, our West Coast launch site.

You can see illuminated in the predawn darkness.

The two stage fact and nine vehicle.

It stands 70 meters tall that's taller than 20 story building.

Now the first stage of the Falcon nine will provide the initial force to get out of the majority of the Earth's atmosphere.

Today's flight will feature stage separation at about 66 kilometers altitude.

If you look closely, you can see the first stage is the part of the vehicle that has the space six logo on it.

The first stage today will be returning to our drone ship named Just Read the Instructions.

It will take three burns of the first stage to get back to the drone ship, which will be located about 300 kilometres down range of launchpad in the Pacific Ocean.

On top of the first stage is the second stage that will take the satellites from the edge of space and accelerate them.

Tow orbital speeds of just over 7.5 kilometres per second, 10 times faster than a bullet.

Finally, on top of the vehicle is the 17 foot diameter payload, faring inside of which are the 10 iridium Next satellites.

Now you can see structure next to the Falcon nine.

That's our transporter Erector.

There's two major parts of a transporter Erector.

First is the launch mount.

The platform at the bottom that the rocket sets upon, and it provides connections into the first stage on the side of the Falcon.

Nine.

You could see the strong back.

That's the vertical tower.

It provides connections to the second stage and the spacecraft.

Now these connections air umbilicals that carry power propellant gases, electrical commands and vehicle telemetry.

Finally, one reminder about the transporter Erector.

It will recline before launch to a position of 77 a half degrees that's different than Lower 39.

A launch is on the East Coast, where the Erector reclines after Falcon nine lifts off.

We're t minus 11.5 minutes, continuing to count down, looking for an on time launch this morning.

Everything on the Falcon nine continues to look good right now.

The Falcon nine team working no significant issues Their problem.

We rolled out on the evening of the seventh.

We went.

Vertical checkouts have done well, and we're currently in the middle of the propellant loading sequence.

We began loading feel a T minus 70 minutes.

Feel is now loaded on the second stage, and we're complete with feel loading on the first date.

Except for a small amount of topping off that will do in the last seven minutes or so of the countdown.

The major activity going on right now is liquid oxygen loading that's in progress on both the first and the second stage is, and that will continue down to the last 3 to 2 minutes of the countdown.

Our next major activities that were going to see are the opening is the retraction of the strong Back then, inside of one minute will be opening the They're starting the flight computer, counting us down for igniting the Merlin engines right before to zero and then released Empty zero.

You may notice in a close up, the White Griffin's these air the aluminum Griffin's.

We're using those today instead of the dark titanium, because this is a return from a trajectory that is less extreme than a geo stationary transfer launch that allows us to use the aluminum on the spacecraft side.

The Iranian team has gone to internal power.

They're working no issues.

Everything's looking good for the 10 satellites for the range were operating out of Vandenberg, the western ranges, providing a similar support.

Airspace clearance C clearance is we use for the Eastern range launches.

And finally, this morning, the weather looks accident.

It's common ground level, upper altitude winds a little bit high, but they're also within acceptable limits.

So everything's looking good.

Falcon nine, the Iridium satellites, the range and the weather for an on time launch in just over 9.5 minutes from now.

T minus nine months.

15 seconds and counting.

Everything looks good right now at Vandenberg.

It's Look for today.

Space X is launching 10 Iridium next satellites to low earth orbit.

This is our third of a planned launches for our customers.

Now, in order to correctly position the satellites, the Space X team has to launch right on time.

So that means this morning our launch window is one second long.

We do have a backup opportunity tomorrow.

If we had to scrub today, the Falcon nine spacecraft second stage will actually send the commands.

Once we get into the proper orbit of 625 kilometers altitude, those commands will individually release the Iridium satellites one at a time, every 100 seconds.

We should get a satellite release in.

That whole sequence will take 15 minutes.

We're going to try to bring it to you later on in the Webcast.

From there, the satellites will maneuver to their final orbit slightly higher from where we drop him off.

Here's Matt Dish of a radium with more on the Iridium system.

This is Matt Dash again.

I feel like I'm a regular contributor to the Space X program because this is our third launch third out of eight, which is crazy.

It's unprecedented.

And I really appreciate all of those who have been following Space X launches and have been following us and have been rooting us along its working thank you and keep it up.

But those of you who are watching your first Iridium launch, let me tell you a little about what a radian does.

Radium is a communication supply.

In fact, where the world's furthest reaching most global communication provider in the world, we provide service to every part of the planet through 66 satellites going around the Earth, all in low earth orbit about 780 kilometres above us, all interconnected and space providing a mesh network of communication that covers every part of the planet.

No matter of, we're an asset that needs to be tracked needs to be just given example, how our satellites operate.

So whether you're on a ship in the ocean, our airplane fake over the North Pole or your own Mount Everest with a satellite phone when you turn it on, it makes a connection to whatever satellite happens to be overhead, and there's a new one every 8 to 10 minutes.

So particularly for those in harm's way or hunkered down in a warm spot in a very cold place.

They don't have to go to the top of the mountain to point towards the satellite someplace in space are satellites will come to our customers and provided that connection because of the way we operate were really a specialty service, we provide a unique safety capability that works when no other communication device works were used in hurricane recovers.

We're using earthquakes were used or making connections to first responders, protecting safety of life during emergencies.

It's the most important things really go crosser.

That's where radiant performs best, and that's what we're best at today.

Almost half of our devices on our network half a 1,000,000 devices are really connections to things, and in fact, you don't even know that iridium is on your bus or on your ship or on your airplane, making a connection, sending information about the engine or the performance or the altitude or speed or the temperature, the humidity.

It's sort of behind the scenes and yet so important to really make machinery and equipment on dhe things.

Run our satellites and quickly, efficiently send data back and forth about anything.

Really, whether it's a piece of heavy equipment or in the oceans where there is no connections, you have buoys things that protect us from tsunamis that can provide early warning, making a connection to a refrigerated container as it travels across the ocean to ensure the cheese and the wine that air within those are stored at the proper temperature.

And they never broke down.

Put on two trucks, service vehicles, railway cars, military's put us on to M raps and tanks and trucks so that no matter where they put them, they know where you'll find them.

Under manhole covers, their systems that relay information about the height of the water and a sewer pipe to ensure that there's not overflows were used in remote cameras to send pictures back of important things like animals or protect trees or tow, have other security or use on border patrol for monitoring remote locations and allow people to call and to track and asked sensors that can tell whether something moved across a certain area.

You can't depend that there's always gonna be a cell tower in those places.

These new satellites are going to make that business run even more efficiently.

It's exciting to see thes things.

You work so long, get into orbit and get into operation especially.

We're excited because the 1st 20 have been working so well.

I really want to get the remaining 55 satellites in orbit as quick as I can.

So launched.

Three.

Don't get tired of me.

I'm gonna be back over and over again almost every two months until we complete this amazing network and see it all in space.

T minus three minutes and 38 seconds and counting down.

Since we last talked with you, the strong back has begun reclining away from the Falcon nine.

It's slick for it.

Van number.

Next major activities were going to get into about three minutes before launch will begin securing liquid oxygen loading on the sex on the first stage.

Two minutes to go before launch, the second stage will complete.

It's E minus.

One minute the flight computers will go into start up and they'll take over the sequence leading to lift off on the Falcon.

Nine.

A couple of words of warning.

We've been loading helium into the second stage.

A final go no go call for that would come just about one minute before launch.

So we'll be listening in case we have not got enough helium on board.

Another warning about T minus 90 seconds.

We begin venting the gases oxygen out of the ground side of that strong back.

You might see a large white cloud coming off of the strongman.

That's normal.

Nothing to be worried about.

You already have.

Satellites are ready to go.

The range is ready to support.

We've been looking at cruise ship, but they're not an issue this morning and the weather looks good.

We've heard stage one locks close out, complete.

We're coming up in the two minute mark.

So let's listen into the terminal countdown.

A Falcon nine with a radiant mission.

Three.

Argosy, this is RC on Countdown one.

Could you confirm that the Rangers green rocking work.

It is on a total power speech to lock secure rock range is green vehicles and so violent.

Schedule A F.

T s is ready for launch Belkin nights and start up stitch to you this start of pressures L d go for launch.

30 20 stage workers that lift up pressures 15.

Welcome to configure for flight 10 nine, eight, seven, six, five, four, three two.

Alliteration GC copies.

Wilco T plus one minute, 17 seconds into flight Falcon nine approaching Mexico.

Ooh, You've heard the call out, Mbacke.

Children will be We're not getting the second States engine ready for ignition.

Several activities coming up here very shortly.

At T plus two minutes and 24 seconds.

We expect main engine cut off, followed immediately by state separation and ignition of the upper stage engine.

Right after that, the first stage will begin the first of three burns to return us back to the Pacific Ocean to the drone ship parked offshore about 300 kilometres down range.

Coming up on Miko, Let me go get that recognition T plus two minutes and 47 seconds into flight.

We've had successful state separation and ignition of the upper stage engine.

And as you can see, we've also relate three of the engines on the first state to begin the sequence that will return it to the drone ship in the Pacific Ocean.

Boost back, burn last about 30 seconds, and we have flooring separation at a brief fear of the Iridium satellites.

Is the fairing separated again?

It's just before dawn as we head south over the Pacific Ocean, so we're not getting any sunlight.

First stage boost back burn did complete Faring did successfully separate.

We're waiting to hear the drone ship a less that's acquisition of signal that indicates the drone ship is receiving telemetry from the first stage.

Second, State Propulsion continues to look nominal coming up at T plus four minutes in the flight, plus five minutes into the flight of Falcon nine carrying 10 iridium next satellites.

Next event in our timeline isn't about 35 seconds.

That will be a second ignition of the Falcon nine.

First stage what we call the entry burn.

This is a burn off three Merlin one D engines that will slow us down for the actual reentry into the earth's atmosphere.

The burn itself will last about 13 seconds.

Meanwhile, second stage performance continues to look at.

The trajectory is good.

Engine parameters look good.

Stage one entry and you see the flare on the screen.

We have start up.

It looks like all three engines are up and running.

Also, you can see saluted.

The grid fins did deploy earlier.

Then I'll be used to guide us as we enter the Earth's atmosphere.

And we've had shutdown of the entry burn Stage one, a TSS Autumn Automated flight Termination system.

Autonomous flight termination system has safety on the first stage.

We're coming up on T plus seven minutes.

Stage one is heading back to the drone ship in the Pacific Ocean.

Stage two, still headed to its initial parking orbit.
