  • three.

  • You're looking at a live view of the Falcon nine rocket as it prepares to launch at 12:45 p.m. Eastern Time from historic Pad 39 a Kennedy Space Center in Florida.

  • Good afternoon, and welcome to the Webcast of Space X C.

  • R S 12 mission launch to resupply the international space.

  • My name is Tom for Dario, and I made firmer engineer in the yards department you're in space is now.

  • Today's mission will mark the final new cargo Dragon spacecraft to visit me, I assess with all future CRS launches from Space X to be conducted.

  • We re use Dragon spacecraft now on your dragon Today are £6000 of cargo, including food, crew provisions, medical supplies, fuel in airports as well as a number of research experiments, which will talk about more during red cats are later on during past.

  • Also today, after the Falcon nine drops that Dragon spacecraft into orbit, the first stage will be attempting to land at our LZ one landing zone back in Cape Canaveral, just a few miles south of the center.

  • On your screen, you can see a beautiful shot had 39 a Kennedy Space Center in Florida.

  • Let's take a look at exactly what you can see on your screen right now.

  • The center of the screen is the Falcon nine rocket.

  • This rocket is comprised of two main stages that bottom 2/3 of the rocket or so is the first stage.

  • This last rocket off lift off just about 11 minutes now to about 100 kilometers above the surface of the earth.

  • And then on top of that is the second stage, which takes the Dragon Spacecraft west the rest of the way into orbit at the very top of the rocket.

  • That nose cone looking thing at the very top that is the dragon and its trunk.

  • That dragon is currently loaded with about £6000 of supplies and experiments.

  • For the I S s.

  • On the back of the stuff, you can see the fixed service structure and rotating structure.

  • These are left over from the shuttle era.

  • Mind today is an instantaneous launch window.

  • So if we don't get a chance to launch in exactly 12:45 p.m. Today, way will be having to attempt again another day, just a small correction that is a lift off.

  • 12:31 p.m. Eastern time today.

  • Now here it's basics.

  • We conduct our go No go pole the rocket at about T minus 78 minutes.

  • This is when the launch director pulls all the launch teams and make sure that all systems rocket are good to go for launch.

  • So a T minus 78 minutes.

  • We did have that.

  • Go No go pole and all systems are go for launch.

  • Way started.

  • Loading liquid rocket propelled.

  • Sorry.

  • RP one fuel.

  • That is our liquid kerosene fuel into the rocket at about T minus 70 minutes and then started loading our oxidizer liquid auction at about T minus 40.

  • We're just about full on.

  • Both are one and liquid oxygen and we'll be full topped off about T minus five and t minus three minutes, respectively.

  • On all that is £1 million total of rocket fuel and across our liquid helium pressure.

  • And started loading about T minus 23 minutes.

  • And we're almost done with that engine.

  • Chill just started.

  • There is just about to start a T minus 10 minutes.

  • This is when we flush those engines of liquid oxygen and get ready to receive their privacy right now, whether it's looking fantastic, as you can see on the camera way, monitor a few weather conditions here from launch.

  • One of them is anvil clouds and lightning.

  • Obviously, those look pretty good right now.

  • No, no lightning and sight.

  • Other things that we monitor are low level winds and upper altitude wins.

  • Both of those are looking fantastic.

  • We just had a report back from the booth weather balloons that launch about every 30 minutes on upper out.

  • The winds are looking pretty great.

  • So with the Falcon nine getting ready to launch, let's talk about what's on board the dragon today.

  • In addition to the food, water and provisions for the crew, there's also a bunch of very interesting science experiments going up today, one of which is an augmented reality system to help the crew better organize their tasks and equipment storage on board the station.

  • There's also a circadian rhythm experiment that's designed to allow scientists to observe how it reacts to the rapid changes in the day and night cycles in terms of scientific equipment.

  • Today, the dragon is bringing up what's called the cosmic ray energetic mass experiment or cream.

  • This is a highly sensitive cosmic ray energy detector for measuring the cosmic ray backgrounds of outer space.

  • Way also have a protein crystallization experiment, which is designed to observe protein teenagers in microgravity in order to learn more about the costs.

  • Parkinson's Disease.

  • Also going up today is a commercial supercomputer experiment that's designed to test the latest generation of commercial electronics against the harsh radiation effects of space.

  • Now most of this cargo is loaded well in advance of the launch date.

  • However, we do have what's called a late period about six hours before the rocket.

  • As you can see here, that late period happens while the rocket is still horizontal on top of the transporter Erector.

  • This gives Space X engineers a last minute chance to vote any cargo that is extremely time sensitive.

  • I suppose anything is refrigerated or any science experiments that need to be prepared right up until so engineers unload those supplies.

  • For once that four hatch is secured with all of the late load cargo.

  • Dragon is then buttoned up to protect it from the harsh environments of launch liftoff, and then the rocket is is rolled the launch pad and hoisted critical.

  • Like I was saying earlier, this is a instantaneous launch window way have launched at exactly 12.

  • 31 Eastern time.

  • If we don't, we're going to be attempting again at the earliest possible time.

  • So once we launch that dragon toe orbit these first it is going to be coming back towards landing zone.

  • One of that first aid is gonna turn around and excuse me.

  • Burn maneuvers first for maneuvers.

  • What's known as a suspect burn.

  • This just cancels out all the horizontal velocity rockets picked up on his way to orbit and sends it back after that boost back burner, There's another bird called the reentry burn.

  • This happens just as the rocket is approaching its top of the atmosphere to slow it down and make sure that thick atmosphere doesn't damage the engines on way back down.

  • And then finally, right before the rocket gets the gets towards the way, fire the engines one more time.

  • What's known as a landing?

  • This takes the rocket from just about a few 100 meters off the pad, all the way down to a soft touchdown.

  • L Z one wait just a notification that stage one fuel load is complete.

  • Rocket Just looking Go for launch.

  • All of our weather indications are looking fantastic right now.

  • Earlier today, we were holding or we're observing in 80% chance of favorable launch conditions and it looks like that prediction is holding true.

  • Like I was saying, box load on.

  • Our one is complete.

  • Aboutthe rocket is going to be turned over to auto sequence.

  • This is when the Rockets internal peers have full control over the launch procedure starting at T minus one minute all the way.

  • We're still getting clearance from the range.

  • Sounds like rangers go for launch today.

  • That white steam looking stuff you see coming out of the rocket is just that liquid auctions slowly boils off that liquid oxygen is just in the inside of those tanks and human Florida airs on the outside.

  • So as we continue topping up on liquid oxygen a little bit boils up that's released, deformed that gases, still getting indications that weather is go from launch rocket is fantastic in these final moments, Dragon is also performing final checkouts to make sure that all its primary systems work as soon as it's released from at this moment, the cradle arms are opening at the top of that transporter Erector tower just left of the rocket.

  • And the final moments before that transporter Erector tower just left of the rocket is going to be back so that the rocket can clear it as it begins to sense.

  • So with just about T minus three minutes to go, we're gonna turn it over to the patent and nets and listen as the rocket prepares to lift off at 31 that's a position.

  • No.

  • And just so you know, you, there's a lot of background noise on your phone.

  • T minus two minutes.

  • Two blocks load closed out vehicles and self line ground side gas close after started.

  • A F.

  • P S is ready for launch.

  • Bc dc verify Falcon on a dragon are started coconuts and start up Dragon isn't started Gaskell's That's complete LD verify Go for launch.

  • Go for lunch.

  • T minus 30 minus 20.

  • Dr.

  • Linus could figure per plate.

  • T minus 10 nine eight seven six 54 three, two, one, zero.

  • Let's talk about copy.

  • Wilco, you are watching the Falcon nine rocket carrying the Dragon spacecraft as it ascends through the atmosphere on route to the international space station after a successful lift off from Kennedy Space Center in Florida.

  • Vehicle has just passed through supersonic territory, and the people has also just passed through Max Q, which is just about 45 seconds sound.

  • The first stage is going to go through a few maneuvers on very close succession.

  • The first of those is going to be main engine cut off its when those nine Merlin engines in the bottom of the first age stop thrusting immediately after that first age going to separate from the second stage and then immediately after that second stage is single.

  • Merlin vacuum engine is going to ignite and prepare to accelerate the Dragon spacecraft the rest of the way towards the orbit of the International Space Station.

  • You can see those exhaust gases from the Falcon nine expanding in the upper atmosphere.

  • Stand by for Miko and just five seconds.

  • And as you can see, the main engines have got off successful separation.

  • Just waiting for that second engine.

  • Start cheering downstairs.

  • Sounds like successful separation and successful mission.

  • With that statement now on your screen right now, you can see that second stage on the right hand side as it accelerates towards the international space station.

  • However, on the left hand side, you're looking at it.

  • You from the first stage of the Falcon nine rocket.

  • That first stage just completed its boost back burn, which thrusts it back towards Cape Canaveral and gets ready for landing.

  • We could fall along with its process back towards LZ one on the left hand side and follow along with Dragon in the second stage.

  • Progress on the right hand side just had confirmation.

  • The dragons nosecone deployed.

  • That is the shield on top of the dragon that protects the hatch in the forward bulkhead from any aerodynamic pressures.

  • Now that we're out of the atmosphere, we don't need it anymore.

  • So we just pop it off, getting confirmation from Archie and see department.

  • The trajectory of the second stage is nominal.

  • Inside, you can see those grid fins deploying on the first date.

  • Those weapons are used to control the first age as it descends down through the atmosphere.

  • Just had confirmation of a successful boost Back burn shut down as well.

  • Periodically, on the left hand side, you'll see jets of gas.

  • These air cold gas thrusters in addition to the griffins, those cold gas thrusters allow that first aid should control its descent so that it can pinpoint land in the center of L Z one.

  • And on the right hand side of your screen, you can see that second stage nozzle glowing hot with those exhaust gases.

  • That second stage is currently accelerating.

  • Nominally towards the I S s.

  • We've just acquired signal as well.

  • From our Bermuda tracking stations, Basics has tracking stations situated all over the world.

  • So we can maintain constant contact with the second stage engine as it orbits the Earth that first age eyes.

  • But one minute away from the entry burn, you can see the coast of Florida in the left hand side of your screen as the stage comes back down towards land.

  • Still, in the very upper regions of the atmosphere, where air is very thin.

  • But before it hits the thicker atmosphere, portions way are going to light those engines once again to slow it down just a little bit, so it doesn't burn up on its way down towards Cape Canaveral.

  • This is a beautiful shot from space of Cape Canaveral.

  • You can see the white dots of clouds that we just launched through.

  • We should be able to get clear video all the way back down towards landing zone one on the right hand screen.

  • You're seeing a camera shot from our pad.

  • LZ one Annie entry Burn has just started.

  • Falcon nine is currently crushing its way.

  • Just slow itself down.

  • Burned last about a minute.

  • Excuse me.

  • About 10 seconds and entry burn has just completed.

  • That was successful for those of us just joining on the left hand side, we have a camera on the first age as it descends on the right hand side, we have a camera on the ground tracking that first age as it makes its way back.

  • You can see the rocket start to vibrate around as it hits the thicker parts of the atmosphere in about 10 seconds.

  • That center Merlin engine is gonna ignite once more and set the rocket down as gently as possible.

  • At the padded LZ, one landing burn has begun on the left hand side.

  • You could see the first age approaching the pad.

  • The right hand side.

  • You see, we had shot.

  • Let's watch it land.

  • You just saw this Webcast on X marks the spot for yet another a picture.

  • Perfect landing of a Falcon nine.
