USSF-44 Mission

thank you alien alien alien alien go for the launch vehicle is supersonic stage separation confirmed Dragon separation confirmed stage one is transonic Landing like this deployed and Falcon 9 has landed good morning you are seeing a live view of Falcon heavy in the historic Launch Pad 39a at the Kennedy Space Center awaiting liftoff at 9:41 a.m. m, eastern time. Welcome to our live webcast of the USSF 44

Mission

from SpaceX headquarters in Hawthorne, California. My name is Kate Tice and I'm the quality systems engineering manager here at SpaceX and I'm excited. being here with you this morning to bring you coverage of our first heavy Falcon launch since 2019.
ussf 44 mission
Today's

mission

is a national security space launch for the United States Space Force and marks our fourth heavy Falcon

mission

of all times and our 50th general launch of 2022 When we first flew a Falcon Heavy over four years ago, we sent Starman on a trip to space and a Tesla Roadster after that demo

mission

in 2018, we launched two operational

mission

s the following year with Arab sat 6A and stp2 payloads. Today's

mission

will be spacex's third Falcon heavy general operating

mission

and our second launch of a US government satellite complex 39a in Florida which, as you can see through the fog on your screen at the request of our customers, we won't be showing views of the payload, so we'll end our webcast right after our falcon 9 side thrusters arrive re-landing on lz1 and lz2 just past t plus eight minutes check flight now as i mentioned before , there's a bit of a fog there at pad 39a, however we promise everything will still take off on time range and everything still looks green everything looks good with our countdown as we get closer to rig minus 13 minutes Mark we have a 90 chance 90 favorability in terms of our weather conditions so even though it's a little cloudy we're still ready to go now for some reason we can't launch today we have a backup opportunity tomorrow at 9:37 a.m.
ussf 44 mission
ET so now we're just below T minus 13 minutes and counting let's take a closer look at the Falcon heavy vehicle that will be carrying the payload USSF 44 to its planned orbit. Mars, like Falcon 9 Falcon heavy, is a two-stage launch vehicle. The big difference is that the first stage of Falcon heavy is made up of three cores and Falcon 9 only has one Falcon heavy which has 28 motors, making it the most powerful internal powerhouse in the world. their call indicates the spacecraft is now internally powered so with all 28 engines this makes Falcon Heavy the most powerful operational rocket in the world by a factor of two each of these cores has nine m1d engines, which makes a total of 27 engines in the three boosters, as you can see in that shot, engine 28 is a Merlin vacuum engine in the second stage and that is what will propel the payload to its final target orbit altogether, the Merlin 1D engines on the base Falcon Heavy produced 5 million pounds of thrust equals 18,747 at takeoff, in fact the engines produce so much power we don't even run them to full throttle all at once, we do it after the takeoff now after takeoff about two and a half minutes into the flight. those two side boosters will detach from the center core and come back to earth for simultaneous landings at Landing Zone 1 and Landing Zone 2 which we have a nice view there on your screen if successfully recovered the side boosters will be restored and will use in a future Homeland Security Space Launch after detachment of the side booster, the center core will continue to fire for about 90 seconds before shutting down its engines and then performing a standard stage detachment from the second stage. we will not be attempting to land our core today as the

mission

requires higher performance meaning to get our payload where it needs to go for today's

mission

the core will burn the fuel we would normally use for recovery for those of you watching up close even though there's a bit of a fog that's why you don't see any landing legs or grid flaps in the center core you'll probably get a better view of that after takeoff now moving towards the second stage once that the first stage and separate second stage will propel our payload into its intended orbit at the request of our customers, we will not be showing views of stage two, so immediately after the Merlin vacuum engine is turned on in the second stage, we'll be directing our full attention to landing our side boosters now above the second stage is where our payload is encased m Safely tucked inside the fairing The fairing protects the payload from aerothermal charges Heating and contamination during ascent Once we reach vacuum m of space we will scrap the fairing while the second stage continues its journey to orbit We will attempt to recover the fairing halves today with our recovery ship doug as i mentioned earlier today's launch is

ussf

44 and that's for homeland security it's a homeland security space launch

mission

for the united states space force now let's learn a little more from our client about the

mission

at hand we depend on space every day to support our way of life our supply chain financial systems weather monitoring and power grids as well as air, land and sea infrastructure our us military is the strongest and best force equipped the world in the hotly contested space domain the command of Space Systems leads a team of approximately 15,000 Guardian civil aviators and contractors based in El Segundo California our unbeatable team operates from multiple locations across the US including two SLD45 space launch deltas at Patrick Space Force Base and SLD-30 at Vandenberg Space Force Base through the Unit Effort in Space Acquisition Enterprise Space Systems Command offers warfighters integrated and resilient space capabilities through five programs Executive offices ensured access to space acquisition launch services and deliver on-orbit capabilities faster and more frequently than ever while maintaining ranges for the United States space force and trading partners, battle management, command control, and communication provide tactical and operational command and control capabilities to war fighters rra, facilitating quality and timely battle space decisions for joint domain, fight space domain awareness and combat power maximizes comprehensive space characterization using a wide range of multi-domain assets by rapidly detecting actual and potential threats for our nation and allies, enabling decisive action in the space domain Communications and positioning, navigation and timing ensure the delivery of resilient capabilities across the prototyping lifecycle to systems on the production line to systems our war fighters have been operating for years space sensing provides space-based battle space awareness through tracking missile warnings environmental monitoring and tactical intelligence surveillance and reconnaissance our adversarial series is fully intended to disrupt, degrade and destroy the ability of s the US and our allies to access and operate in space not under our control. we are now at almost T minus six minutes and 30 seconds and the SpaceX team is continuing the countdown to the launch of our third operational Falcon Heavy flight and all systems are still working at this time the refueling is also complete on the second stage as one of the side boosters and there we just heard the call that the fuel load is now complete on one of the boosters on the other side as well as the center core now after a successful static fire last Thursday, the Falcon heavy rolled onto the pad with a payload yesterday and went upright about six hours later, you can see a time lapse of that there on your screen before we start the webcast today, SpaceX launch director gathered to the members of the launch team and tested the loading and launching of props which as I just mentioned were currently in the works we are loading propellant r on all three first stage and second stage boosters now you may be able to hear the sounds of the rocket live from our launch pad.
ussf 44 mission
The clicking and hissing sounds you hear are from the propellant charging as well as the launch assembly and strong back propellant is flowing through Falcon heavy uses two propellants refined form of kerosene called rp1 or propellant rockets one and that is the fuel and the locks or liquid oxygen for the oxidizer an oxidizer is a type of chemical that a fuel requires in o To burn, liquid oxygen is cooled below its boiling point so that it has a much much greater mass per volume. Basically, we can load more into the rocket. Our fuel is essentially a purified kerosene. a lot of history as a fun fact the phone of the first stage of Saturn V from this very platform for

mission

s to the Moon also use liquid oxygen and carrots and heavy tanks push for a strong back retraction and then we hear the call we are preparing for that strong back retraction Now in addition to the two propellants I mentioned we also use the chemical t-tep or triethylaluminum and triethyl as an ignition source.
ussf 44 mission
The combustion of rp1 and the locks is what makes the rocket go up and it's the t-tub that basically sets the match started for that low back strong propellant mix and we can see uh there on your screen shortly that we'll start to to see the strongback begin to retract out of the fairing in preparation for that cla retraction The arms suspended around the second stage opened up and that allows the strongback to recline away from the vehicle now as I mentioned earlier this is our first flight Falcon heavyweight in three years and a lot will happen in the first four minutes of flight. the two side thrusters followed by the center one for about 40 seconds after takeoff we will decrease power on the two side thrusters in preparation for Max Q, after which Falcon heavy will then lock throttle and float is complete never heard the call of one of these sides The thrusters are now complete with their locks loaded fully charged with all their thrusters and then it looks like we can see a strong pull back happening. thrust on the two side boosters this time to decrease the forces on the overall rocket structure the vehicle at that point will be much lighter but the thrust remains constant at tw After a minute and a half of flight we turn off the boosters completely Sides with Drive Motor Cut or Pico.
ussf 44 mission
This pneumatic charge is complete. We hear the unlocking of the call stage, so it is complete. Right now both side boosters and center 4 are now fully charged with their liquid oxygen and rp1 uh once out of the side boosters uh the center core will throttle to full power and until the center core cuts out of the main engine or Mikko and will then separate from the second stage at around the four minute mark from then, much like Falcon 9. The

mission

's side boosters will return to Earth for recovery, the fairing will separate and the second stage will take the

ussf

-44 payload into space just as a quick reminder in the At our client's request we will not show views of the payload so we will end the webcast right after our side boosters return to land on lz1 and lz2 and that will be a little after t plus eight.
ussf 44 mission
The mark stage two lock load in the minute of flight is complete so we hear the call stage two lock load is complete so right now the Falcon Heavy is now fully loaded with all of your boosters as i mentioned as i mentioned before in the previous webcast launch is difficult falcon heavy is no exception because it essentially counts down three rockets simultaneously so our team will be conservative in case something comes up in the last few minutes of the countdown regressive plus the fog around the launch pad we can see some of the white clouds around the vehicle totally normal thats just the liquid oxygen uh basically uh vaporizing as it comes in contact with ambient hair, now that those closures are complete, as we just heard the call, we should see more of that next.
I will hear the call thatFalcon 9 is and startup Falcon heavy not well started right now Falcon Heavy onboard flight computers have taken over launch countdown great view of Falcon heavy base there MD LD go for launch Will this is the void the MD is ready for launch there we listen for the last launch attempt give us 30 seconds let's listen to the final countdown as Falcon heavy prepares to go into space one more time 15 seconds factoring in T minus ten nine eight seven six five four three two one zero lift off vehicle is magic range now rated power and telemetry pounds of thrust directed into space throttle down in preparation for Max Q moment of maximum mechanical stress on Falcon heavy rocket is supersonic there we just heard the call that the vehicle is now traveling faster than the speed of sound what a beautiful sight Max Q very good there we just heard the call that's e l moment of peak Mechanical stress on the motors of the m1d rocket accelerating backwards a beautiful sight to see Falcon flying heavy once again we will surely hear the mbac cooldown call indicating that the second stage is preparing the mbac engine all the trajectory what will we do I flow some super cold liquid oxygen through the turbo pumps in that mvac in preparation for the full stream of super cold propellant shots there from each side booster on the right hand side of your screen The next event will be the booster engine cutout or Biko which will be followed by the separation of stages of the side boostersside booster boost back Burn Center core cutout of the main engine we are about 10 seconds from the booster separation for the confirmed separation and there you can see and hear it on the incredible excitement within the crowd behind me successful separation of the side boosters there we can see three engines in each refu side erzo have been turned back on for later power up right now both side boosters are coming back those are following nominal trajectories good news both side boosters and center core all looks good side boosters are coming back on Florida coast now under the power of three engines which is a sight there central core looming three events happening in rapid succession we will have the conclusion of the side booster booster back burn followed by the main engine cut out as well as the stage separation of that Core Center as a reminder per our client's request, we will not show views of the second stage after the second engine start, besides our Core Center or Stage One, the one you see there is Expendable today, so that we're not getting back, uh, this booster whose background Nico turned off.
The separation of the stage confirmed there. the main engine shut down on the separation of that center core and we heard the call for second engine one start right now with that separation of the call confirmed we'll wrap up our second stage related coverage by keeping our focus on the side boosters you see there sadly looks like a position the chambers in those side thrusters are a bit foggy we hear confirmation of successful fairing separation as the second stage continues on its journey the fairing halves will fall back to Earth where we will attempt to recover them using our recovery vessel Doug as a reminder today we will try to get the two Falcon heavy side thrusters back on the ground you can make out some cloud cover the re on the back camera we will get it back to you whenever we can now in just a few minutes the side thrusters will execute a burn inlet followed by a landing burn to Both burns are intended to slow the side thrusters quickly before landing at the time of Detachment, the side thrusters were traveling slow enough to turn around and come back to land on our side by side landing pads .
If we have successful landings today it will mark the 150th and 151st successful landing of an orbital class rocket as I mentioned earlier the center core will be spent and we won't try to recover it this allows us to use all the vehicles follow the nominal trajectories allows us to use all propellant on board and deliver maximum performance for the payload. the delivery on the left side of your screen is a live view of Hawthorne

Mission

Control here at SpaceX headquarters. We're about 30 seconds into the entry burn for the two side boosters they're on. At the top and bottom of the right side of the screen, the outer side booster entry burn there we hear the call that the booster entry burn has the weapon on the outside.
All vehicles continue to follow the nominal trajectories so that the re-entry burn is complete. expecting the landing burn to begin in about 30 seconds the entry burn was intended to significantly slow the vehicles as they re-enter Earth's atmosphere amazing follow-up camera views of the boosters as they return to the landing zone one and two we can see the grid flaps there are transonic thrusters stage two FTS is safe stage two is in terminal orientation we can see those grid flaps directing the thrusters for a precise landing again we are trying to land landing zone one and two chairs we have successfully landed cooking heavy side thrusters in landing zone one and the Landing Zone tool what an amazing sight with these two side thrusters this marks the 150th and 151st successful landing overall it is a rocket of orbital class, this is the 21 Landing in Landing Zone one and the fourth landing in Zone d e Landing two and with successful confirmation of our side thrusters Landing which will end today's webcast We would like to thank the United States Space Forest for entrusting us with today's
