  • three.

  • It's October 30th 2000 and 17 at 3:24 p.m. Eastern.

  • Daylight time are 1920 Universal Coordinate time and you're looking at a live view of a Falcon nine rocket As it awaits.

  • Lift off from the Space six launchpad approximately 10 minutes from now.

  • Welcome to today's live Webcast of the Korea Sat five.

  • A mission from Launch Pad 39 a at the Kennedy Space Center in Florida.

  • My name is John Better Spiel and I'ma lead mechanical design engineer here at Space X, and today we will be delivering the Korea SAT five, a satellite to a geo stationary transfer orbit, also known as CEO.

  • Now, as with our previous GTO flights, we will also be attempting to recover our first stage by our drone ship.

  • Of course, I still love you currently stationed in the Atlantic Ocean, about 340 nautical miles downrange of the launch pad.

  • Now we did have some rough seas due to a tropical storm that passed by the Bahamas in the earlier, but the drone ship is now on station and looking good for recovery.

  • If successful, today's landing would mark our 19th overall successful landing.

  • Today's launch will mark space Axis 12 from Launch Complex 39 a and 16 launched overall this year.

  • On your screen, you're seeing some footage of the Space X hangar located the base of our launch pad.

  • This hangar can house both Falcon Man and Falcon heavy.

  • And in fact, our launch today for Falcon nine was prepared right next to the three boosters Currently hangar for Falcon Heavy, which were targeting tow launch by the end of this year.

  • Curious at five A.

  • Was made it to Falcon nine last Friday and rolled out to the pad and raised vertical about 24 hours ago.

  • This operation was done while the vehicle was supported by the strong back.

  • That's that white structure you see.

  • Vi lo The rocket on that is what cradles the rocket up the ramp to the pad and a rex it vertically as you see it now on your screen about T minus five minutes or so.

  • Well, actually, open up the Ford arms of this strong back recline it back about a degree and 1/2.

  • That's how we check out that ground system lead up until the T minus zero market lift off where that strong Rex going to recline about a 55 degree angle right at lift off.

  • Now Falcon nine itself.

  • It's a two stage rocket.

  • First stage has nine Merlin engines.

  • That's what we call a Falcon nine on.

  • It's about 2/3 of the overall height of the rocket.

  • Midway up your screen, you see the Griffins just above those is actually the parting plane from our interstate for a second stage.

  • That's actually what will separate, and the first state itself will come back in land of the drone ship once it basically gets us out of most of Earth's atmosphere.

  • The second stage.

  • That's what actually is going to be doing.

  • The precision orbital maneuver it uses a single Merlin engine optimized the vacuum of space to place Korea sat 58 into the Geo stationary transfer orbit.

  • Korea sat five a Is house inside are faring at the fort end of the stage.

  • That's the area that's a little bit of larger diameter and has that Katie sat logo on the outside about three minutes and 39 seconds.

  • Today's flights will be separating that faring, and it will fall back.

  • Thio, the Atlantic Ocean as well.

  • But T minus nine minutes days mission.

  • Right now, all systems are go tracking no issues at the moment.

  • We began voting propellants of the T minus 78 minute mark.

  • Right now we have finished loading RP one.

  • That's our fuel for today's mission.

  • We finish loading it on the second stage.

  • We're going to top off our P one on the first stage up until the T minus five minute mark.

  • We are currently loading liquid oxygen and sitting nearly full on both our first and second stages, and we'll continue loading liquid oxygen onto those both status up until the T minus three minute mark.

  • We try and hold that to his latest possible because we cryogenically cooled liquid Austin down to about negative 340 degrees Fahrenheit on.

  • Then we load it onto the stage so it says dense as possible.

  • So get as much propellant on the stages and give ourselves as much margin for the mission coming up at this.

  • At this moment, it's about T minus eight minutes.

  • We did check out our spacecraft.

  • Korea set the transition to internal power about T minus 20 minutes.

  • They're gonna go for today's mission.

  • Tracking no issues.

  • Wear Also launching from Kennedy Space Center s So we're working with Kennedy Space Center team as well as the Cape Canaveral Air Force Station.

  • They have cleared the area and security around launchpad 39 a.

  • They've also cleared the corridor leading out of the pad down range and given us a go for today's mission.

  • Looking at the weather.

  • It's a beautiful, beautiful, beautiful blue sky, 65 degrees and sunny at Cape Canaveral, tracking no issues at the moment for weather eso, with all stations indicating go for lunch.

  • Let's take a little closer look at today's payload.

  • Korea Sat five A is a communication satellite operated by Katie Set.

  • It's Korean, South Korea's soul satellite service provider, The Sad.

  • It was manufactured by Tallis Alenia Spots and located at 113 degrees east longitude.

  • Korea sat five A will provide director home broadcast broadband and back haul Service's with its K U band capacity.

  • Korea Sat 58 provides Katie set with 12 K U band transponders of 36 megahertz and 24 K u band transponders of 54 megahertz.

  • Now, as a replacement for Korea sat five Prius at five a.

  • Will stand upon its coverage across Asia in the Middle East.

  • Unlike other satellites in Korea, sat fleet Prius at five a will provide maritime coverage of the Persian, both Indian Ocean, South China Sea and East China Sea Korea Sat five is also equipped with four extended K U band steerable transponders of 54 megahertz.

  • The serum transponders provide commercial director Home Broadcasting Service is in the North Asia region.

  • By the end of this year, the Korea SAT five.

  • A satellite arrived at Space X facilities in early October and has been undergoing preparations for launch today, it weighs about 3700 kilograms at launch and offers Halo power of approximately 6.5 kilowatts.

  • We're seeing that side of getting loaded into shipping picture on the screen right now that was brought into an airplane, ships Cape Canaveral and arrived the basics abilities.

  • Justin that transfer great, you see right there now Talus Alenia Spots is the prime power contractor for Korea.

  • Sat five, a in charge of his design, production and testing, as well as the ground delivery the companies also responsible for its launch campaign launch and early operations phase and in orbit testing of Korea sat five a.

  • Now, today we are taking Korea set five A to a geo stationary transfer orbits.

  • And on your screen we have a quick animation.

  • You can see the launch with first stage landing.

  • That second stage has its first burn.

  • After that burn, we have as sparing separation during it.

  • We will coast for about 20 minutes that we're gonna have a second stage second burn about T plus 35 minutes and 30 seconds.

  • We're gonna have our payload deploy.

  • Then Korea sat five able you tone onboard thrusters.

  • Put it in a final geo stationary orbit at about 36,000 kilometres away from Earth.

  • You can see it's matching Earth's rotation.

  • That's how it actually covers a singular spot of earth sky and in this region in since 113 degrees east latitude longitude position.

  • So we're about T minus four minutes and 20 seconds in today's mission.

  • As of right now, we're finishing up that locks load on the first stage.

  • No issues report.

  • Right now, the Ford arms of the strong back have begun opening up.

  • Everything there is looking good to reports it will fully recline at lift off at T minus seven minutes.

  • We began the engine chill process of our first stages.

  • That's where we actually are flowing in that liquid oxygen into the first stage engines that kind of chills down all of the all of the metal components of the Merlin engines.

  • That way, they don't actually flash into gaseous oxygen at lift off, protects the engines and get it ready for the actual ignition points coming up at the T minus one minute mark Falcon nine is gonna enter into startup.

  • That's actually the moment where our ground computers are going to hand over the countdown process to Falcon nine.

  • The onboard flight computer of Falcon nine will take over the countdown.

  • At that point, it'll do.

  • Its final checkouts of all the sensors will lead us up into lift off AT T minus zero mark.

  • So recap in where we're at right now are paler is on internal power.

  • Given us go for today's lunch are faring.

  • Boat is our drone ship is out in the C three and 40 nautical miles.

  • Vote for today's launch Our Rocket Falcon nine go for today's launch topping off liquid oxygen.

  • Right now.

  • Weather is looking good.

  • Range is good.

  • So at about T minus three minutes, let's listen in to the final few minutes of the countdown process.

  • Statement Statement.

  • Locks is closed after flight.

  • That countdown one confirmed T V C is nominal.

  • Stage two TVs.

  • Emotions nominal.

  • Stillings will give the launch stage too long since closed off for flight vehicles itself.

  • One gas close up.

  • A F.

  • T s is ready for launch.

  • How can I?

  • Doesn't start up?

  • Guess close.

  • That's complete stage.

  • 2%.

  • L D on Countdown one.

  • We're go for launch.

  • C'mon, Stage one, President 15 seconds.

  • Stand by for terminal count nine eight.

  • Okay, Bye.

  • Four, three, two, one.

  • Here.

  • Vehicle pitching down.

  • Range decision.

  • Proposals nominal.

  • Our delivery nominal.

  • 50 seconds in today's mission.

  • We're on our way to delivering three Sat 58 to make you a stationary transfer Orbit watching nine Merlin engines of the Falcon nine.

  • First stage nine people putting out over £1.7 million of thrust out.

  • Five seconds ago, we transitioned supersonic regime coming up about a second.

  • We're gonna take Maxie back down and pressure actually just passed through Mexico.

  • You?

  • That's one of the highest stress states in the vehicle.

  • Potion may be honest, continues to look phenomenal.

  • And back in Churchill has begun.

  • You heard the call out.

  • The Merlin vacuum engine of our second stage has begun chilling.

  • In same process of the first stage, we start to flow that liquid oxygen through that second stage engine.

  • This first stage burn will last for about another 38 of us in about 10 seconds.

  • Will have main engine cut off.

  • All nine Merlin engines at that first stage will shut down about three seconds.

  • After that, we will see stage separation where the first and second stages will be separated by 40 Matic actuators.

  • And then we will have the ignition of our second stage engine.

  • Let's watch where'd you go?

  • And we have a good ignition of the Merlin vacuum engine.

  • For a second stage, you can see the exhaust plumes coming from the forward view of our first stage on the left screen camera.

  • Our great offensive also deployed.

  • As you can see there, we use those grid fins to guide ourselves back through Earth's atmosphere to our drone ship.

  • Of course, I still love you.

  • About 15 seconds will have separation of the fairing from our second stage.

  • That's a view inside a fairing Korea sat five day on the right side way of separation of the fairing Good separation ages following a normal trajectory and we have a call out.

  • That second stage is following a nominal trajectory right now, everything looking good.

  • Meanwhile, first stage is continuing to guide itself down coming up on entry burn at about six minutes and 23 seconds for the entry burn.

  • Now, in addition to using those grid fins for guiding ourselves back to the ship, we do have a cold nitrogen thrusters.

  • That's those white puffs of smoke you see coming on the screen.

  • The first stage image.

  • We also use that to help Orient stage back to the drone ship.

  • Our second stage burn is going to last two about T plus eight minutes and 30 seconds.

  • Then that second stage engine will shut down will be coasting for about 20 minutes on.

  • Then we will have our second burn to put Korea sat by they into the final geostationary transfer orbit and you burn coming up in about a minute for the stage one.

  • It passed through its apogee of about 110 kilometers.

  • So now we're accelerating back to Earth.

  • We use that entry burn to negate a lot of the vertical velocity that the rocket is built up on hope.

  • Slow down the entry speeds.

  • I'll see more gentle touchdown entry burn will be about a 22nd entry burn we used in combination of one and three engines depending on different timing and sequences of this burn.

  • Today there is only two birds.

  • Since we are landing on the drone ship, we're not going back.

  • Thio Cape Canaveral.

  • So we just have the inter burn followed by the landing burn at about eight minutes and six seconds.

  • Gyp us stage one stage on every bird is confirmation of entry burn start 22nd burn.

  • Stage two continues to follow a normal trajectory Stage old engine, Burn his shop and we have shutdown of the entry burn Expected Lots of people kicking up.

  • We'll have our landing burn in just about a minute of stage one single engine landing burn.

  • We may lose signal as you saw their brief of the stage one.

  • We are getting the feed from a satellite.

  • The drone ship with that tropical storm moving through the area.

  • There were some choppier sees, which makes our satellite link a little bit more challenging.

  • But we will provide you guys updates as we have them.

  • Meanwhile, you're looking at a live you stage all of these Transfer call out for stage one passing through and Sonic Regime just came.

  • Trajectory continues to look good for this second burn.

  • Our first burn of the second stage, which will have cut off in about eight minutes and 30 seconds.

  • Stage ward leading burgers started.

  • The landing burn for stage one has begun.

  • 32nd landing burn live you from.

  • Of course, I still love you.

  • Ar drone ship out in Atlantic Ocean we have We do have confirmation while we're waiting for a new image from the drone ship that we did have our second stage engine cut off.

  • But if you turned in the past and Webcasts, you've noticed that we have lost feeds in the past.

  • Our stage one Right now we don't exactly know the state of stage one, but as of this moment, it doesn't look like we are in a good parking orbit for stage recovery.

  • Stage one is late.

  • Did recovery way have confirmation from recovery operators that stage one has landed.

  • Stage one has landed.

  • We don't have any images.

  • Footage share with you.

  • There's an image right now, little toasty.

  • But stage one is certainly still intact on the drug shit.

  • Our second stage isn't a good parking orbit right now.

  • So what we're actually going to do is leave you this animation of stage two way.

  • You can keep tracking its progress at about T plus 26 minutes.

  • We'll be back to cover thesis Bird of our second stage.

  • Put it into a geo stationary transfer orbit.

  • So we'll be positive right now.

  • It will see you back here at 26 minutes.

  • Look.

  • Okay.

  • I think T plus 26 minutes and 15 seconds in today's mission.

  • If you're just joining us, we had a successful first burn.

  • We have a live view of our first state.

  • They're on our drone ship.

  • You saw it a little bit toasty earlier with fires.

  • Those fires are out.

  • Our team missed a control of it.

  • First stage is looking good, right on point in the center of Of course I still love you in the mid Atlantic Ocean.

  • If you look back at our primary mission today, second stage is coming up on its next burn.

  • That will start in about 10 seconds.

  • That's a live view from the aft end.

  • Looking at our Merlin vacuum engine of the second stage were right now sitting in a good lower parking orbit.

  • In about two seconds, you'll see ignition.

  • And there it is, Ignition of our Merlin vacuum engine.

  • This will be about a one minute burn.

  • That burn will take us into Ah, hire apogee.

  • This is what this is doing.

  • This raising the apogee of second stage, getting ready to deploy Korea sat five a into that geo stationary transfer orbit this burn, like I said, uh, so far looks good.

  • Um, we will be executing this burn for about 30 more seconds, And then after the burn finishes, we will be coasting for about another eight minutes and then we'll have payload deployment.

  • Right now From that animations heart tell.

  • But we're off the western coast of Africa.

  • Engine looks good throttling down, and we have shut down and it looks like we're in a good Geo stationary transfer orbit.
