You are currently looking at a live you over recovered a Falcon nine rocket on the space X launchpad as it awaits its second launch, its landing back in February of this year.

Welcome to today's Webcast of the Space X EchoStar 105 s.

E s 11 Mission from Launch pad 39 A at Kennedy Space Center in Florida.

My name is Tom for Dario and I'm a firmer engineer here.

The first stage of a Falcon nine rocket you see today on the pad was previously phone as the first stage of the sea Arrest 10 Mission, which was a mission to resupply the International Space station earlier this year.

Today we will deliver the EchoStar 105 s.

A geo stationary transfer orbit target, which is what you'll hear us.

Today's launch will be our fourth launch for S.

C s First was SCS eight back in December of 2013 and the most recent was C S 10 in March of last year.

This is Also our second lunch for EchoStar.

1st 1 being EchoStar 23 in March of this year and with previous GTO flights, Geosynchronous transfer orbit way will be attempting to recover the first layer of our rocket on the drone ship.

Of course I still love you, which is currently stationed off the coast of Florida in the Atlantic Launch Complex.

39 A is the same launchpad that launched Saturday.

Five rockets carrying the Parliament as well as Space Space X leads this pad a few years ago and started launching from the pad.

At the beginning of this year, we've constructed a massive hangar, the Palace's Ghost Falcon nine and Falcon Heavy, which, of course, has three first stage boosters instead of just one vehicle you're looking at today was rolled out out of the hangar and raised a vertical on the launch pad about 24 hours ago.

A CZ you could see in your stage is currently still made into transporter Erector, which carried out of the hangar you can see the rocket has two stages.

The first stage is about 70% of the height and second stages remaining.

30% of these are both made of aluminum structure connected by a composite interstate.

On the very top is the fairing, which is made of a composite material as well, carrying the EchoStar one of five.

Once that first days launches today, it's also going to be attempting to return into the atmosphere and land on the throne ship.

Of course I still love you, which is our East Coast run shit.

This will be our 18th landing, with the most recent landing attempt occurring just a few days ago on Monday, which was the Iridium free throughout today's Webcast, I'll be bringing you status updates during the countdown and all the way through Flight Falcon nine you're looking at today rolled to the pad late Tuesday afternoon and went vertical and about T minus 24 hours.

We've been loading propellants, which is R R P one and liquid oxygen into the Rockets team on its 78 minutes, which is the same as we've been doing for the last flights.

Current generation of Falcon nine has its go no go pole at about T minus two hours.

As you can see that go no gold fool went well.

We're currently in the process of loading fuel.

Loading fuel on the second stage is nearly complete, and we're topping off in the first stage.

We've done the initial load and we're currently in a planned PAS phase while we load helium for the final flight mass.

Once we confirm we have enough, helium will resume walks looking at about T minus two minutes.

Currently, the EchoStar and SCS team has reported their satellite is in great condition and ready for market range is also reporting, ready to support the launch today.

The area was cleared, the entire area around at the end.

It was clear, uh, this morning and last night.

We monitor several weather conditions, one of which, being low altitude winds and other being upper altitude wins and also rules like anvil cloud rules and lightning conditions.

It is a beautiful cloud free day at Cape Canaveral couldn't be more perfect weather for one.

So with all stations currently indicating go, let's take a closer look at the countdown clock and watch a rocket as it approaches.

Oh, as we said before, today's payload is the co star 105 s, Yes, 11 satellite.

As we're waiting for the countdown to get a little bit closer, let's take a look at exactly what this payload is.

You reusability is the fundamental breakthrough needed to reduce the cost of access to space.

A fully and rapidly reusable rocket, which has never been done before, is the key to establishing not just outpost but also self sustaining cities on other plants.

Now, the cost of fuel for each flight of the Falcon nine is only about two 100 to $300,000 which is only about 4/10 of a percent of the cost.

The majority of the launch costs comes from building a rocket, which, if it only flies once, makes for a very expensive ride.

However, recovering and reusing the rocket multiple times way commercial airliners used over and over again significantly reduces the cost of an individual flight.

Since the capital expenditure to build the vehicle could be spread out over many plates.

Being able to reach you reduce the props to the rocket on use it as a potential is the key to establishing a city on Mars way need to get the cost of a watch down to a level where a critical mass of people could actually afford.

Let's take a look at how the rocket is doing as we get closer and closer to lift off.

The first stage in the second stage of the rocket are almost fully loaded, with about £1 million liquid oxygen total.

Continue topping off both fuel and liquid oxygen until about T minus two minutes that c'mon, it's seven minutes.

We had an engine chill just when we flushed those tensions departments in Maryland.

Nine engines with cold liquid oxygen to get him to the operating temperature in the next few minutes.

First of all, that strong back transporter record to the left of the rocket is going to retract slightly and then fully recline as rocket leaves pads with their rocket is currently also pressurized helium.

A good part of the rocket strength comes from the pressure inside the tanks.

We use helium that pressure at about team on 60 seconds.

The Rockets internal flight computer is going to take over.

You'll hear a call out on launch jets saying started.

Sounds like a team of saying the payload is going to go.

Range is good and weather is crystal clear.

In the last few minutes of the camp, stage two lakhs.

Gaskell's that started a F T s is ready for launch night doesn't start up 45 seconds.

So state problems card telemetry nominal.

You're watching the Falcon nine rocket as it ascends through the atmosphere carrying the EchoStar 105 s.

E s 11 payload geo stationary transfer orbit.

After a successful lift off from Kennedy Space Center in Florida in about 10 seconds, the rocket is going to be passing through the period of maximum aerodynamic pressure that is called Max Q.

Nine Merlin engines, currently thrusting, produced the first of seven foot sorry 57 47 at full thrust that so much power vulcanized producing right now, Beckett until it started in about 30 seconds, those nine Merlin engines are going to shut off events called Miko, which stands for main engine cut off.

Once Miko happens, there'll be two other very quick succession stages happening after that.

The first is going to be the stage separation, where the first age separates from the second stage and comes back towards the drone ship.

And then, after that second engine start one, which is when the Merlin vacuum engine on the second stage ignites to carry the pale of the rest of the way toward it.

You can hear the applause from Mission Control.

It looks like that we had a successful mico main engine cutoff, successful stage separation and a successful start of the Merlin vacuum engine on the second stage.

For those of you just joining us on the left hand side, you can see the first stage of about nine rocket currently expanding its Griffin's getting ready for its ascent or descent back down through the atmosphere and on the right hand side of your screen, you can see the engine nozzle of the Merlin vacuum engine on the second stage.

In about 10 seconds, we're gonna see the fairing, which is protecting the EchoStar 15 GS 11 payload deployed from that second.

Cecil Deployment faring is only needed while in the dense region of the atmosphere to protect it from aerodynamic loads.

Now that we're out of the atmosphere, we can jettison acquisition of signal.
