It's Wednesday, March 18th and you're looking at a live view of Falcon nine as it awaits its 8:16 a.m. Eastern time launch from pad 39 8 at Kennedy Space Center in Florida.

Welcome back to Space six headquarters in Hawthorne, California My name is Jesse Anderson, and I'm a lead manufacturing engineer here at Space six.

You're watching a live webcast for our six Starling mission in our six mission over all this year in 2020.

If you joined us on Sunday morning, you know that we had a standard auto abort triggered right before liftoff at Space six.

We intentionally hold down the rocket prior to liftoff to ensure engines reach correct power levels.

On Sunday morning, we had an out of family engine reading, which caused an automatic abort.

Typically, we would try again the next day, but today was the first available day on the range.

Today we're launching a set of 60 Starling satellites.

StarLink is designed to provide high speed, low latent see Internet all over the globe, particularly and remote or rule areas where connectivity is limited or completely unavailable.

Today's mission will also be the first time we're flying a booster for the fifth time.

The most recent flight of this booster was our second Starling mission back in November.

Just like our first stages, we are also starting to reuse our fair ings.

Today we're flying a reused bearing which previously flew on our first darling mission.

With that, all systems are go for an on time lift up this morning.

My name is Michael Andrews, and I'm a supply chain supervisor.

Here it Space six, and this is our Falcon nine Vertical once again at Launch Pad 39 a down at Florida's Kennedy Space Center.

The bottom 2/3 of the vehicle the part of the vehicle looks to be covered with soot is our re flown first stage.

This first stage uses its nine Merlin and one D engines to power the vehicle through the earth's atmosphere out to the edge of space, and today will be attempting to recover that first stage again.

Actually, for the fifth time on our drone ship, of course I still love you, which you concurrently see it's stationed about 350 nautical miles northeast of Kate.

It connects the second stage at the top, which will carry our 60 starling satellites to a deployment altitude of 440 kilometers above the earth's surface.

From there, they will be deployed and use their individual propulsion systems to move up to their operational altitude of 550 kilometres.

The falcon nine you see on the pad has been loading propellants since t minus 35 minutes.

As a reminder, we use a mixture of rocket grade kerosene known as R P one and super chilled liquid oxygen known US locks to power.

The Falcon nine Currently, our RPI one is nearly fully loaded in the first stage, and it is 100% loaded on the second stage Locks.

Loading, however, is still underway on both stages, and that will actually continue to be topped off right until the last minute of our countdown.

And at the very top is our stack of 60 starling satellites there, safely enclosed inside that 17 foot diameter payload faring.

It's the pointed cone on the very top of the rocket and, like we've attempted in our past couple launches will be attempting again today to recover the fairing pieces again with our to recovery ships.

They're currently positioned in the North Atlantic Ocean off the coast of North Carolina in terms of weather conditions.

Today we do have a few scattered cumulus clouds, but nothing gating us from today's launch winds.

Both that ground in altitude are nominal.

The Air Force range is prepared to support today's mission.

So with that, our vehicle are starling satellites, the weather and ranger all looking green for an on time lift off just a few minutes from now.

As I mentioned at the top of the Webcast, today's launch will be the 1st 5th flight of a Falcon nine booster, and if we land it successfully, it will mark the 51st recovery since we started landing our boosters back in December 2015.

Reusability is core to our mission here at Space six.

Which brings me to our efforts underway in Boca Chica, Texas, where we're building and testing Starship, our next generation spacecraft.

If you joined us Sunday for our first attempt of this mission, we shared an update on Starship in the progress that the teams in Boca Chica are making.

The local team has executed a variety of tests designed to push the limits of the vehicle, and the site continues to change daily as production ramps up.

We have a Siri's of upcoming static fire and short flight tests with our serial number three test article and longer flights with zero number four.

But ramping up our Starship and Rapture production line is what matters most.

The design goal for Starship is three flights per day on average, which equates to roughly 1000 flights per year at greater than 100 tons per flight.

This means every 10 ships would yield one mega ton per year toe orbit.

This is a significant effort, and we're looking for highly skilled engineers and welders to help us make this a reality.

If you're interested in joining the team, please take a look at space.

Six dot com slash careers were currently T minus 4.5 minutes from lift off, and Falcon nine is now moving into the final stages of its countdown back at T minus seven minutes.

This is where we allow a small amount of that super chilled liquid oxygen to flow into the Berlin engine.

Turbo pumps parts of the full flow of liquid auction into the vehicle.

You have to realize that our RPI one is coming in at about 15 F, but that liquid oxygen is less than negative 300 degrees Fahrenheit.

This engine chill helps us avoiding kind of any kind of thermal shocks to our system.

Liquid oxygen is also what's creating the white clouds you see around Falcon nine Way.

Continue to load that super chilled locks into the stage just before liftoff, but when that locks comes into contact with the Indian air around it, it creates those clouds that you see because of boiling.

And at the right below, the fairing is our cradle.

If those arms that hold the vehicle in place, they just opened up at around T minus 4.5 minutes in.

Right now, the transporter erector, that vertical truss structure is starting to slowly retract a few degrees.

It may be hard to see, but guaranteed this retraction is enough for Falcon nine.

Clear a path in terms of propellant the first and second stages when you add up that kerosene fuel liquid oxygen.

That vehicle will finish prop loading at T minus two minutes, with the first stage locks being at 100% in the last call out, your he'll be here before go go.

One minute, you'll hear that Falcon nine is in start up mode.

This means that the Rockets autonomous internal flight computers have taken over the launch countdown.

Our starling payload continues to be healthy.

The Falcon nine team is tracking no issues on the rocket, whether it's still looking good and the Rangers green for launch so that all that's left to do is listen in to the last few minutes of our countdown and did she locked his clothes out vehicles and start up L D is go for launch.

10 nine, eight, seven but five for three, two one Hero.

It's T plus 40 seconds, and we've just had lift off over Falcon nine vehicle taking our starlet payload to its targeted deployment orbit.

We are now throttling down and darling back up in preparation for Max Q, which is coming up here in about 10 seconds or so.

Excuse the maximum aerodynamic pressure that the vehicle sees throughout.

The largest structural load that the vehicle will see should hear that call in about five seconds.

Maximum aerodynamic pressure and there's that.

Confirmation that we've just passed through Max Q.

Coming up in about a minute, we will have three events in rapid succession, the first of which, being main engine cut off or what we call mico.

This is where all nine of our M one D engines shut off and slow the vehicle down for the falling event, which is stage separation.

And that's when the first stage separates from the second stage.

And then finally, the lighting of our second stage em back engine, which we call S E.

Now, if you've been following our starling commissions, you know that we've reduced the number of burns on the second stage for these missions from two burns down to just one single burn.

This allows theseventies stage to provide 70% of the velocity needed for this mission, which allows the first stage to use less fuel and thus making first aid recovery much easier.

So today we will again on Lee be doing one burn of that second stage engine again.

Are those three events me go stage separation and s E s one me Go on separation back condition.

And there we've just had Mico on stage separation.

That stage separation confirms the successful fifth use of our first stage booster.

And you could see on your right screen that second stage em back engine lighting up, taking the second stage to its targeted orbit.

We're just a few seconds away from faring deploy again.

This bearing was used once 1/4 in the very first Starling Commission and there is the visual confirmation of faring deploy.

So this means that we've successfully reuse the sparing.

So now let's see if mystery Miss Chief can catch those bearing hats.

Today we likely won't have that live you since bearing touchdown won't happen past the conclusion of this morning's Webcast.

But stay tuned to our social media for updates later this morning.
