  • you are looking at a live view of the Falcon nine as it awaits its 9:19 p.m. Eastern time launch from Cape Canaveral Air Force Station in Florida.

  • Good evening.

  • It is January 6th.

  • Here it Space X headquarters in Hawthorne, California My name is Lauren Lions, and I'm an engineer on the StarLink team here at Space Six and welcome to the first space X launch of 2020.

  • Now, as many of you know, we just launched 60 Starling satellites back in November and today will be launching another 60.

  • That, combined with the additional 60 we launched back in May, bring our total count of Starling satellites launched over 180 with Starling Space X plans to bring high speed, low latent see brown bet broadband Internet to people across the globe, particularly to places where connectivity has been unreliable, too expensive or even completely unavailable.

  • Our goal is to start offering service in the northern United States and Canada later this year, expanding to a near global constellation after another 22 launches.

  • And of course, the more launches we have, the more opportunities we have to re use these boosters in fact, this one will be entering its fourth flight, the one that you see right there on the pat.

  • This first stage first flew the Telstar 18 Vantage mission in September 2018 followed by the Iridium Eight Mission in January 2019 and most recently, our first launch of 60 Starling satellites back in May 2019.

  • We're going to be attempting to recover this Falcon nine for stage for the fourth time on our drone ship.

  • Of course, I still love you, which is currently stationed about 339 nautical miles off off the east coast of Florida.

  • Way will also be attempting to recover a payload fairing that sorry AP lit for 1/2 using one of our fairly faring recovery vessels.

  • Mystery.

  • We're continuing countdown to liftoff right now, But if for some reason we have to call hold on, today's launch will have a backup opportunity.

  • Tomorrow, January 7th at 8:57 p.m. Eastern.

  • But at this time, all systems are go for an on time liftoff.

  • My name is Jesse Anderson, and I'm a lead manufacturing engineer here at Space six.

  • Right now we're looking at a live view of Falcon nine hour, 70 meter to stage liquid fueled launch vehicle.

  • Falcon nine rolled out to the pad with the payload and went vertical.

  • Early this morning, the chief engineer held a technical pull at T minus one hour and launch director held a propellant load and launch Go no go pole at T minus 38 minutes.

  • Falcon nine has been loading propellants since t minus 35 minutes, and currently our rocket grade kerosene or what we call our P one, is nearly fully loaded on the first stage, which is the bottom 2/3 of the vehicle that you see there on the screen.

  • The first stage is responsible for accelerating the vehicle through Earth's atmosphere to the edge of space with the help of nine Merlin engines.

  • Above that first stage is the second stage, which has a single Merlin vacuum, or EM back engine, which ignites after the first states separates.

  • The second stage is what will carry the starling satellites to an altitude of 290 kilometers above the earth's surface.

  • At this time, the second stage is fully loaded with fuel and liquid oxygen is loaded, is currently loading on both stages.

  • The stack of 60 satellites is safely enclosed inside of these 17 foot diameter payload faring, which is the pointed in closer on the very top of the rocket, and you could see that right there on your screen.

  • Once we reach the vacuum of space, we will deploy the faring as the second stage continues on its journey toe orbit.

  • As for whether looks like we have some mostly clear skies with some light winds overall looking good for an on time launch today in Cape Canaveral.

  • But we will continue to monitor this all the way down to T minus zero to ensure that weather remains good for launch.

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

  • Waters are clear of any ships and the range continues to ensure the safety of our launch.

  • With that, the vehicle satellites, weather and rains are all looking good for an on time lift off just a few minutes from now.

  • Now, if you've been following starlings development, you might know that most satellite Internet service is today come from geo stationary satellites.

  • These air single satellites that orbit the planet at about 35,000 kilometres covering a fix region above.

  • The starling, on the other hand, is a constellation of multiple satellites that orbit the planet at a much lower altitude at about 550 kilometres, and they cover the entire globe and because they're in a low orbit, the roundtrip data time between the user in the satellite, also known as Leighton See, it's much lower than with satellites in geo stationary orbit.

  • This enables starling to the liver.

  • Service is like on line gaming but are usually not possible.

  • Another satellite broadband systems after the startling step satellites are deployed from Falcon nine at 290 kilometers above the earth.

  • They'll use their on board I am thrusters to raise themselves to their operational altitude of 550 kilometres.

  • As you may recall, these ion thrusters air powered by Krypton making starling first Krypton propelled spacecraft ever flown Now during orbit raise.

  • The satellites are closely clustered together and their solar arrays are positioned in a special low drag configuration, making the satellites appear visible from the ground just after deployment.

  • However, once the satellite's reach their operational altitude and began on station service, their orientation changes and the satellites become significantly less visible.

  • While it's really cool to catch a glimpse of those satellites from the ground, they can sometimes be a distraction.

  • For astronomers.

  • It's on this flight.

  • StarLink is testing an experimental darkening treatment on one satellite in order to further reduce the light reflection on the satellites.

  • Way also make early satellite tracking data available to astronomer so they can better coordinate their observations with their satellites.

  • Thes measures, along with our work with leading astronomy groups, will enable Space X to bring Internet access toe underserved and unserved populations around the world without materially impacting views of the night Sky Way are currently about 5.5 minutes from liftoff.

  • Falcon nine is now moving into the final stages of the countdown.

  • At T minus seven minutes.

  • Engine chill began.

  • This is where we allow a small amount of these super chilled liquid oxygen to flow into the Merlin engine.

  • Turbo pumps prior to the full flow of liquid oxygen into the vehicle to avoid any shocks to the system, liquid asked.

  • Oxygen is also what is creating the white puffs around Falcon Knight.

  • We continue to load super chilled liquid oxygen or locks into the stage until just before liftoff.

  • And when that super chilled liquid oxygen comes into contact with the ambient air around it, it creates the clouds that you will see around the vehicle on your screen right there and just a few moments ago are coming up in about 15 seconds, actually, at T minus 4.5 minutes.

  • The transporter Erector will retract away from the rocket slightly and provides in clearance of Falcon nine for lift off.

  • You should be able to see that on your screen.

  • The first and second stages are both nearly fully loaded with £1 million of kerosene fuel and liquid oxygen.

  • First stage should finish profit loading at T minus three minutes and second stage at T minus two minutes at T minus 60 seconds.

  • Fisher toe Listen in for the call out that Falcon nine is in startup.

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

  • Starling payloads continue to be healthy.

  • The Falcon nine team is tracking no issues on the rocket.

  • Weather is looking good.

  • The range is green for lunch, so let's listen into the last few minutes of the countdown.

  • One down to lock load goes down.

  • Vehicle on internal Power Falcon.

  • And isn't startup go for it.

  • T minus 30 seconds.

  • T minus 15 seconds, Ted.

  • Nine, eight, seven, 543210 Ignitions.

  • We are t plus 45 seconds into lift off.

  • And we have just had lift off of our Falcon nine vehicle carrying our starling payload.

  • In just about 15 seconds from now, we will be passing through Max Q.

  • This is the largest aerodynamic pressure that the vehicle will see throughout a cent.

  • We've got an awesome view of lift off right now.

  • Vehicle is passing through maximum dynamic pressure.

  • And we just heard that call out for passing through Max Cube.

  • Now, coming up in about a minute will be a rapid succession of events Main engine cutoff for what we call Miko, followed immediately by stage separation and SCS one, which is second engine start.

  • Now, Miko is where we shut down that main engine on the first stage booster to allow the vehicle to slow down just enough to separate.

  • Still stage.

  • If you're just now joining us, we have an awesome onboard view of our vehicle, Falcon nine and in about 30 seconds will be those three events.

  • Mico main engine cut off stage separation and S.

  • E s.

  • One.

  • And there is me, coz you saw those engines shut down.

  • Stage separation confirmed on there is separation and second engine start.

  • You could see that second engine on your right screen glowing bright red.

  • Now, in about 20 seconds, we will have faring deploy and we should be able to see this on our screen as well.

  • And on that left screen there you could see the grid fins.

  • It's it's a bit dark on the east Coast right now, so hard to see.

  • But we did see those grid fins deployed.

  • Faring separation confirmed.

  • There is faring deployed.

  • So, as Lauren mentioned earlier, we will be attempting to catch one of the fairing halves on a recovery vessel mystery.

  • But we will not be able to show this live.

  • So check in with our social media for updates.

  • Acquisition of signal Bermuda.

  • That is beautiful.

  • Now there are a series of events coming up with both stage one and stage two before we reach our parking orbit and into that first Coast phase.

  • The first is the stage one entry burn.

  • That is when Stage one is re entering the Earth's upper atmosphere.

  • It will reignite three of its Merlin one D engines in order to slow the vehicle down as reenters so that it doesn't break apart because we want to live.

  • That burns gonna last for just under 20 seconds or so, and at that point the burn will end.

  • You'll hear the call out entry burn shutdown.

  • A couple minutes after that, we will see our Stage one landing burn.

  • That is where we will reignite one engine E nine and someone right in the middle.

  • And it's going to burn for just over 20 seconds and hopefully leave stage one standing up nice and tall on that drone ship, but at the very same name of little trajectory.

  • As you just heard second stages on a nominal trajectory.

  • That's really good news.

  • And speaking of second stage, right is the drone ship lands.

  • You should hear the call out for Seiko one.

  • That's where we shut down the second stage engine to enter that coast phase.

  • So far, Stage two's trajectory continues to be nominal.

  • Stage one has also drifted up to its highest altitude and is now beginning its descent.

  • That image over to the left.

  • It start outside dark in space.

  • Yeah, right.

  • In about 10 seconds, you should see that that entry burn start.

  • Stage one entry Brent started.

  • They joined Entry Burn Shut down.

  • We just had to get shutdown of that entry burn.

  • Meanwhile, the second stage continues at full power with over £200,000 of thrust Stage two following nominal trajectory.

  • It looks like we lost signal, but that's fine.

  • Should be acquiring Meet again soon.

  • Now a stage two continues to burn taking those starling satellites to their first parking orbit.

  • Stage one is coasting down, steering its way, using those grid fins down to the drone ship at about T plus eight minutes and three seconds right around there.

  • You're gonna see that landing burns start on Inter Trans Sonic.

  • But as you just heard, we've just gone transcending on stage one as it's making its way back down to the drum ship.

  • So the atmosphere is actually what's slowing vehicle down stage one as it re it's now re entering the Earth's atmosphere and coming down to the thicker parts.

  • That's what slows the vehicle down.

  • Stage one landing burns.

  • Start up.

  • Right.

  • And see that light on the left stage.

  • Terminal guidance stage on lining like the boy.

  • Yes, way another landing.

  • This is the fourth landing vehicle.

  • Falcon nine.

  • First stage landing today way.

  • Video time.

  • That was alright.

  • Stage two still doing where you're safe.

  • Seiko should be coming up any moment.

  • Go and we just may have lost video.

  • What?

  • We've heard Confirmation Sicko capable of us expected.

  • And let's listen to see if we're gonna get order.

  • All right.

  • GNC has confirmed good orbital insertion.

  • Now at that, we're about to enter a coast face, so we're gonna take a quick break.

  • But we'll be leaving you with this cool animation that lets you visualize where falcon in the Starling satellites are on orbit.

  • We'll be back at about T plus 44 minutes for a second stage relight followed by another deployment of Starling.

  • 60 satellites.

  • Loss of signal expected.

  • Newfoundland kun iliac position.

  • Okay.

  • What?

  • No.

  • You know.

  • Wait.

  • Okay, Okay.

  • Okay.

  • Signal going, Hilly Expected.

  • It's and okay, it's which.

  • Yeah, you know, brief acquisition.

  • Okay.

  • Okay.

  • Okay.

  • Act wait.

  • Backhanded chill.

  • Welcome back to the Webcast for StarLink.

  • So far, we've had a on time liftoff of our Falcon nine vehicle.

  • Our first stage made its way back in landed for its fourth time on.

  • Of course I still love you.

  • And second stages on its nor nominal trajectory trajectory.

  • Right now, coming up.

  • Next, we have SCS to followed immediately by Seiko, to which a second engine cut off.

  • Now, this will be one of the shortest burns of the Merlin vacuum engine that we do.

  • The burning is short because we don't need a big adjustment in the orbit, but a little bit will go a long way here.

  • That's coming up here in about 30 seconds.

  • We've got a live view of the second, the second stage engine there, and we're only burning for just one second.

  • So it may not look like much, but it will be lasting one second.

  • And there was our quick SCS to followed by Seiko too.

  • Now we're just waiting to confirm good orbit.

  • GNC confirms good insertion accuracy, and we just got that call up for good orbit.

  • So now that we are in good orbit will be coasting for the next 15 minutes or so.

  • So we'll be back around T plus one hour in one minute for payload to play.

  • Come on, knobs lost.

  • Signal expected from Why wait later.

  • Acquisition of signal Tasmania.

  • Okay, well, welcome back to the Webcast for StarLink.

  • We are getting ready for payload Deploy.

  • Now.

  • The 60 starling satellites are flatly stacked on top of Falcon eye for efficiency.

  • So all 60 salaries, all 60 satellites, are gonna be released all at once.

  • It's gonna look a bit different from other separation sequence is you've seen aside from startling, of course, once released from Falcon nine, the satellites solar disperse, they might even bump into each other, which is totally okay.

  • They were designed with this in mind.

  • We're currently less than a minute away from deployment, so let's wait till we get that acquisition of signal and watch it live.

  • Tension rods released to payload.

  • Deploy confirmed.

  • All right, you just heard the call out.

  • Let's wait till we get that video again.

  • Here we go.

  • That's all 60 of those starting satellite on their merry way.

  • It's a beautiful sight just to give you guys an update on the fairing.

  • We didn't catch it This time we got really close, but we're gonna keep on trying again and to give you more updates as that continues.

  • And with that, that brings our Web class to a close.

  • Thank you to the 45th Space Wing for range safety today to the F A A for licensing today's launch and a thank you to the FCC for licensing operation of the satellites.

  • We'd also like to thank all of our viewers for tuning in, follow our Web site and social media platforms for updates on our next missions and milestones.

  • Thanks for joining us for the first launch of 2020 and, until next time, have a Happy New Year.

you are looking at a live view of the Falcon nine as it awaits its 9:19 p.m. Eastern time launch from Cape Canaveral Air Force Station in Florida.
