Good morning or evening, depending on where you're tuning in from and good afternoon to our viewers in Japan.

On your screen, you can see the Falcon nine rocket against the jet black canvas of the Florida night sky.

I'm Michel Hamersley and materials Engineering our avionics department, and I'm talking to you from outside Mission Control at Space six headquarters in Hawthorne, California As we're getting ready for tonight's launch of J.

Sant 16 we have ah, reasonably unobstructed view into mission control at the moment, which is a rarity on small crowd developing behind me in anticipation of Lift off at 1:26 a.m. Eastern or 8:26 a.m. Coordinated universal time.

C Sound 14 a few months ago, and this mission tonight will have a fairly similar mission profile.

It's also going to be a geo stationary transformation.

Orbit will be lifting off from Cape Canaveral, ascending to that GTO with a second stage burn, Coast fades and another second stage burn, and the first stage will be landing on the drone ship.

One of the big differences will be attempting a single engine landing burn instead of a three and then landing burns.

We hope to be bringing you good footage of that all night.

I'm a firm or engineer in the avionics department.

Now, for those of you who have never seen a Falcon nine launch before, let me walk you through exactly what you're gonna be seeing on the pad before the launch tonight.

So the first and foremost the large structure in the centre of the pad that is the Falcon nine rocket.

The Falcon nine rocket is broken up into three different sections, the bottom section being the first stage, which takes up about 80% of the height of the rocket.

And then at the very top there is the payload, which is tonight the J.

C sat 16 satellite going to geo stationary orbit.

C sat satellite right now because it's encapsulated inside the payload faring.

Now the fairing is that nose cone shaped structure at the very top of the rocket.

And what it does is it protects the satellite inside from the intense air that forces of the launch as the rocket ascends to the atmosphere.

Now, right now, the rockets being held vertical by the transporter erector or strong back tower right here.

That's that structure that's just to the left of the rocket.

It's connected to the top of the rocket via the umbilical, which has electrical connections and plumbing that keep the rocket connected to the pad in communication and also keep it topped off with fuel.

As we prepare for launch, the rockets also held down to the very bottom like gigantic hold down clamps.

These are massive steel clamps that grabbed onto the bottom of the rocket and actually hold it down until all nine Merlin engines are ignited and confirmed to be operating nominally.

We then release the rocket, and it ascends to the atmosphere also in the patter for lightning towers, and you can kind of see through the darkness of the pad right now.

What these do They just protect the pad electronics in the rocket itself, from the lightning strikes that can be very common during the Florida weather.

There's also a hangar just around the corner over there that the rocket was assembled horizontally and then rolled out to the pad throughout the mission.

You're also gonna be seeing a mission countdown clock in the top right hand corner of your screen and then at the very bottom is a mission Progress Park Mission Progress Bar has different types of events that are gonna happen all the way to the launch so you can keep track of exactly what's gonna be happening right all the way down until count until lift off in just a few minutes.

Hi, I'm Kate Thais, a process improvement engineer here in Space six.

This is the eighth Falcon nine launch of this year, and on this flight, we're launching J.

It's a communication satellite that will serve as a backup to the existing fleet of Sky Perfect J.

Sat Saddle Falcon nine will be sending it to Geo stationary transfer orbit, which you may here's refer to as G T.

As usual, will be taking you to Orbital Mechanics School later on in our Webcast, so we'll talk more about the details of GTO.

Also on deck for tonight is a drone ship landing attempt of the first stage.

The rocket's guidance coordinates are set for the drone ship called Of course I still love You, which is currently holding position in the Atlantic Ocean a couple 100 miles off the coast of Florida.

Due to the extreme velocities and eating, the first stage is subjected to upon re entry from a GTO mission.

However, Tonight we're channeling our inner Simone Biles.

To date, we've had three successful jump ship landings as well as two successful manned wins.

The last time we scared it carried a sky perfect.

Jason Payload was Jaycee sat back 14 back in early May of this year.

That was actually the very first time space, like, successfully landed a GTO mission back on a drug shit.

That vehicle is currently at our testing facility in McGregor, Texas Way fired it up three times for static tests in late July, and you could see it there on your screen now, since it was a spoke exposed to such extreme conditions upon re entry from the J.

C Sat 14 mission, it's now being, you know, being utilized as are flown benchmark vehicle.

This means that will perform numerous static fires on the vehicle to evaluate what kind of wear and tear the stage and its components experience from each round of testing.

Getting a better understanding of this is an important next up to our path to reusable rockets, which, of course, is what we are trying to do here.

We're trying to develop a rapidly re a rapidly reusable rocket system, an awesome step towards achieving that goal.

Hello, I'm John, his Burger Falcon nine Principal integration engineer.

I'm coming to you from my desk here at Space six headquarters in Hawthorne, California.

I'll be bringing you status updates during the countdown as well as during the flight of Falcon nine carrying J.

Sent 16 into GS stationary transfer orbit.

Now it's late in the evening here in California, early morning at Cape Canaveral.

But again, employees are beginning together out in front of the Mission Control Center in preparation for another Falcon nine launch.

Now, we're deep into the launch auto sequence right now.

Everything on the Falcon nine continues to go.

Well, is we proceed through this launch out of sequence.

We're deep into the propellant loading right now.

Currently, we are loading liquid oxygen into the first and second stage of the Falcon nine.

You can see the view on the camera, the gashes oxygen boiling off from the ground systems along the transporter.

We also began loading fuel at T minus 35 minutes.

Currently, feel is loaded on the second stage and we're getting ready to wrap up.

Propellant loading consisting of liquid oxygen will continue up until about the T minus two minutes.

We rolled after the panda T minus 17 hours.

We can normally do it in about four hours before lift off.

But once we got to the path that allowed our customer the J.

Set 16 crew to be able to do their spacecraft functional checkouts at about T minus 10 hours, the spacecraft team is completed.

They went to internal power That pretty much completes their activities.

Other than monitoring the spacecraft for the rest of the countdown, the Air Force range is ready to support with all the assets, and the weather continues to look good, both ground level and upper altitude winds for an on time watch in just over nine minutes, The Falcon nine rocket is capable of launching payloads to many different types of orbits.

Now communications satellites typically go for geo stationary orbit and user typically protected inside fairing.

That faring typically just protects the satellite, which, you can see is not really designed to go through launch level winds.

Now, tonight we're launching the J C Sat 16 satellite into geo stationary orbit.

This is actually the second Jason SAT side like we're launching for Sky Perfect J sat.

Jason has 16 satellites in orbit, making it Asia's largest satellite operator.
