Universal Coordinated Time on Friday, May 27th 2016 and you're looking at a live Falcon nine on the pad in Cape Canaveral, Florida Good evening, and welcome to the space X launch of TyCom eight Geo stationary transfer organs.

My name is Brian, and I'm excited to be all the way back from the lot sites here at company headquarters in author in California.

Now I'm currently just standing outside of Mission Control Center, where inside the glass beyond the viewing employees operators are gearing up to answer the countdown.

Now today's launch will be occurring in about 20 minutes at 17 40 Eastern time, or about 2:40 p.m. Here on the local Pacific coast today, we'll be placing TyCom eight's a communication satellite into orbit, Sucks said.

It delivers coverage to parts of Thailand's India and Africa.

We'll talk more about the specific mission later, as well as provide status updates on the vehicles and attempt to give you another live viewing of the landing with an exciting program ahead of us.

I'm a firmer engineer in the avionics department here.

Now it's looking like a beautiful day to launch a rocket at Cape Canaveral Air Force Base on the Space coast of Florida.

Now Cape Canaveral Air Force Base actually has many launchpad, some for NASA, some for the Air Force and some other private launch contractors.

But Space Launch Complex 40 which is what you see right here on your screen, is operated exclusively by Space six for the Falcon nine rocket.

We actually like to launch from Cape Canaveral because it's just about as low latitude as you could get in the contiguous United States, which allows us to utilize the full momentum of the Earth's rotation as we launch east out over the ocean.

Now let's get a little familiar with pad and what you're seeing in your screen Big structure.

Right in the middle is the Falcon nine rocket, and we actually assemble the Falcon nine rocket in a hangar that's just off the screen.

We assemble it horizontally and what's called the transporter Erector.

That's that support structure that's currently standing right next to the rocket.

So we assemble it horizontally on the transporter erector and then roll out on big rails right launchpad and erected vertically.

And then, just before liftoff, the transporter erector actually lift.

It leans back just a little bit to allow the rocket to the tower.

The of these lightning powers around these are essentially just big lightning rods, so that when lightning strikes and it happens very often in Florida, it doesn't damage the rocket or any other sensitive pad electron.

It's now the Falcon nine is actually just a stack of tanks, really.

It's made up of three different sections of the first age, takes up the bottom 60% of the rocket.

Then on top of that is the second stage, and then finally the payload fairing right at the very top.

Inside, those tanks were super cold liquid oxygen and compressed kerosene or RP one fuel.

These really, really cold, cold fluids are separated from the hot, humid Florida air by only a small, thin aluminum skin.

Which is why you could see some that condensation smoke boiling off.

It'll continue to happen right to be in the launch, so just assume we'll be watching in just a few minutes here.

And I'm a mission integration engineer here at Space Sets.

Today we're launching Ty Come eight, which is a 3000 kilograms tie communications satellite, and we're taking it to Geo stationary transfer orbit.

Once the satellite reaches its final orbit Geo stationary orbit, it will provide Southeast Asia.

South Asia in East Africa with broadcast and data service is this is actually space six second time launching a TyCom satellite first was TyCom six back in 2015.

Today, we're gonna be continuing our experimental efforts to lay the first stage of the Falcon nine on our autonomous spaceport drone ship.

In this case, of course, I still love you off the coast of Florida like our last flight, which was Jaycee sat 14 just a few weeks ago.

This is also a geo stationary transfer orbit mission where the first stage is expected to see extreme velocities and reentry heating on its way back to Earth, making this another challenging landing.

But while sticking this landing is not entirely likely, As you saw with that last flight, it's also not impossible.

That marked our third successful landing and our first landing of a rocket.

That payload to geo stationary transfer orbit, which means the stage is traveling much faster and had far fewer remaining propellant tanks in the previous two lower orbit landings before it.

After hitting the atmosphere atmosphere at 6300 kilometers per hour and experiencing five times the aerodynamic heating of the CRS eight landing before it, Merlin engines related only 850 meters above the earth, touching down at four kilometers per hour at a near two meters from the bull's eye at the center of the drone ship and all that, with only three seconds propellant remaining in the tank.

Well, today's landings expected to be similarly challenging.

There's no guarantee that we're gonna get the same result as last time, but we're still gonna try our best to bring Falcon nine home over the course of the Webcast, will talk about what our plans are for that J.

The future of the other two, Falcon nine for stages of 39 A will also tell you about this TyCom satellite.

Its purpose trajectories on and follow it up with a little rocket.

Science 101 We've got a ton of really cool stuff planned today before we jump in.

Let's get an update on the status of the Falcon nine.

I'm John Frederick Steele, a lead mechanical design engineer.

And as you know, we're launching the TyCom eight satellite to a geo stationary transfer orbit.

Now, I've been following along with today's countdown and the good news at this moment is all stations are go and we are lurking.

No issues at the moment on as you know, yesterday we postponed our launch attempts out of an abundance of caution.

Now, for every launch care out, extensive checks and as part of these checks we found that the motion of an actuator on her second stage engine which is basically what we used to help steer the vehicle, was slightly off.

This actually is responsible for directly gimble in the engine in flight, which allows us adjust the vehicles, pitch and yaw through a cent.

Now the behavior we saw yesterday was likely not a risk to a successful flight.

It's always better to be safe than sorry.

So our team took the extra time to address this issue and since then we have performed continuous checks across the Falcon vehicle and we are currently working no issues at the moment, looking full on our refined kerosene RP one full on.

We're tracking nominal Phil rates for liquid oxygen right now nearly full on stage one and continue to fill up our stage two tanks.

At the moment, we're gonna keep filling up that stage to tank right up until about the two minute mark, trying to make sure that the liquid oxygen is as cold as possible.

Meanwhile, the TyCom eight satellite transition to internal power at the T minus 40 minute mark their tracking no constraints at the moment for today's launch and are also good and ready to go, and the rains also been checking out their radar tracking systems.

They are also standing by and ready to support, tracking no issues at the moment.

Speaking of the weather, though, that's time.

The last thing of the four main checks we look at, we are tracking a 20% chance of violating.

The only thing that would potentially setback today's launch would be a cumulus cloud rule.

Right now, everything continues to be go, though, for today's on time launch at 2:40 p.m. Eastern Standard time.

And so to recap, both Falcon nine TyCom ate the range and weather are go for today's launch As the audience starts to trickle in Behind me, let's take a moment to discuss about the customer and the specific mission for today.

So the customer is TyCom and the mission is TyCom ate.

These guys have been launching satellites all the way back since 1993 with TyCom one of the seven that they previously launched.

Four are still in active service out in space.

The others have been decommissioned, so today will mark the fifth satellite that will be up there, providing coverage to specific surface regions of the earth.

Calm eight was built by Orbital 80 K out in Virginia, and it follows the Geo Star bus.

This is a bus with a lot of history, and Taik, on eight for today's mission, will actually be flying the next generation of that Geo star to bus.

Space X's second stage will take it all the way up to what we call Geo stationary transfer orbit for G t o the spacecraft itself with onboard propellant.

Well, then send itself all the way back up to Geo stationary orbit or Geo.

Now, why are those both called Geo stationary?

It's because the angular velocity of the satellite in its orbit is the same as the rotation rate of the Earth, although both bodies are in motion there in motion together.

And so you stay above the same continents on Earth.

This is really important for communication satellites that wants to focus their radios on a specific region now, in terms of technical specifications of today's TyCom eight satellite size wise, it's about 3000 kilograms for a mass reference on the ground that's the size of a rhinoceros.

The satellite is going to be up there for 15 years in a nominal mission duration.

So in order to stay up there, it has to solar wings that it extends out with four panels on each side so they can't remain power positive in the course of years and years and years, and also has reaction wheels to stabilize itself around three separate axes So it is a tried and true satellite design, and it will be going up to geo stationary transfer orbits after a quick stints on the Falcon.

Now the TyCom made satellite is currently on top of the Falcon nine.

You just can't see it because it's encapsulated by the ferry.

Now the fairing is this nose coach coach shaped structure on top of the rocket way.

Use the fairing to protect the payload or anything else we're launching into space from the intense air that enforces launch.

Now, when we unlike the Dragon capsule, which is designed to reenter through the intense heating of the atmosphere when it comes back from orbit, most satellites going toe low Earth orbit or geo stationary orbit are a little light.

They're kind of not built to withstand was really high, tense air force.

So what we do is we capsule itself fairy.
