DETONATION Suppression System for the Starship Orbital Launch Mount!

this episode is sponsored by brilliant [Music] hey Starship addicts my name is Zach golden and welcome to another CSI Starbase Special Report today we're going to be discussing the new water system tested on the orbital launch Mount last week there's been a lot of speculation about whether or not this is spacex's attempt at a minimized water Deluge system as you can tell by the title I don't think this is the case but I have a feeling that I might be in the minority here so the mission for today is to convert every single one of you over this side in order to do that we're going to have to review all of the available evidence first by the time we're finished I have a feeling that many of you will finally start to have just a little bit more confidence that SpaceX can actually pull off a 33 engine static fire without destroying the orbital launch mount in the process welcome to CSI Starbase special reports so let's start off with some basics what is water Deluge well I looked it up and uh the only official definition I could find was by someone under the name of Merriam-Webster so apparently water Deluge is defined as an overflowing of the land by water or a drenching rain on most launch pads around the world water Deluge is used to reduce the damaging effects of high amplitude sound waves produced by rocket engines during the ignition sequence and up until the point where the vehicle has cleared the pad there are a lot of great resources out there that go into more detail about how these systems work like this one from interesting engineering which I've Linked In the description if you would like to know more about the physics behind water dilute systems as you can tell these things produce a ton of water initially SpaceX planned to have a monster Deluge system similar to the one for SLS this is how it is described in the natural resources section of the program environmental analysis if used for sound and vibration suppression SpaceX would discharge up to 350 000 gallons of water per static fire or launch event as far as we can tell that's definitely not in the plan for Starbase because this is what a 335 thousand gallon per minute Supply pipe looks like as you can see these things are so large you could probably drive a Mini Cooper through it like that one scene from The Italian Job on the other hand at the pad 39a site in Florida SpaceX is still in the process of constructing its second Starship launch pad one of the biggest differences here is that this one is already showing signs that it will receive a rather significant dilute system one that is so large that is actually visible from several miles away you can see it right here in this amazing shot taken by fariel mohans I've been keeping an eye on this massive six-sided ring structure for months now waiting to see how it would turn out and as of last week we can finally see that there appears to be a large number of eight inch diameter pipes that have been attached to the manifold pointing straight up into the air luckily we were able to get a view of this from the ground as well when CSI field agent WL animal took these images while on the Kennedy Space Center bus tour in these images you can just barely see portions of the massive manifold on the ground on the right side of the image you can see future inlets for two massive water supply pipes also visible on the top of that manifold are six groups of large nozzles coming out at a 45 degree angle and then pointing straight into the air there are 192 of these nozzles arranged in a pattern around the ring I'm pretty confident that when this is finished it will be flipped upside down and mounted around the exterior of the launch platform this will most likely be used to create a massive waterfall in between each of the six legs during static fire tests and launches looking at the potential water supply SpaceX is nearing completion on what we think is a massive elevated water tank there is a major difference in capacity between this tank and the one used on the Falcon 9 launch pad next door to capture the half a million gallons of water that will be ejected by the system SpaceX has already begun Excavating what I believe will be the future retention pond it's located a little over 100 meters away from the launch mount I'm pretty sure the situation is going to continue to progress rapidly if you don't want to miss out on all the updates be sure to follow both fariel and Greg Scott on Twitter for more amazing photos of the Kennedy Space Center complex continuing on now that we know what a deluge system is we can move back over to Starbase and review the pre-existing Waterworks system on the orbital launch Mount you know the one that was in place prior to the booster 7 explosion a few months ago let's start over at the source the water that SpaceX uses for daily operations here is stored inside of these two tanks at the orbital tank farm these were initially planned to be cryogenic methane storage tanks but were converted for a new purpose after the initial water tank failed if you missed the huge Deep dive investigation into that you can click the link at the top of your screen and then come back to watch this after all right so the two water tanks are connected together via this large black pipe when the valves at the bottom of the tanks are opened the water that is discharged is routed underneath the driveway and then over to the fluids bunker once inside of the mucker most of this water is used as a working fluid inside a group of large heat exchangers that are the most important component of the autogenous pressurization system for the GSE tanks this is something we will discuss more in a future episode anyways a very small amount of this water is either pumped or hydrostatically fed to the launch Mount it's hard to know for sure which method is being used here the reason I expect this to run off hydrostatic pressure alone is because if you look at the launch Mount from far away you can see that the bottom of the deck which is where the water nozzles are is about half the height of the GSE tanks in the background so as long as the water level in the tanks is higher than the bottom of the launch Mount then no pumps should be needed to push the water out at the other end once the water leaves the bunker it travels through this pipe which comes out from behind the berm and then turns down into the ground it runs alongside the edge of the pad until it re-emerges at the base of the launch Mount from there it travels up to the bottom of the walkway before it splits off in either Direction doing a full circle around the bottom of the walking platform there are 12 pipes evenly spaced around the orbital launch Mount that tap into the supply manifold and run underneath the skirt of the table there are two of them located between each pair of columns as you can see here using this close-up from RGB aerial photography you can see what the end of the nozzle looks like except I think we're going to need a little bit of enhancement here if you could Jeff okay much better as you can see here at the end of the pipe is a spiral nozzle that is designed to spray water or gas in a cone-shaped pattern similar to this this picture from Elon is really great for giving us an idea of where the nozzles are located in relation to the engine Bells given the proximity to these engines and the fact that we haven't seen these used during any of the static fire tests it's safe to assume that this is not for sound and vibration dampening like an actual Deluge system the important detail here that gives away their purpose is the fact that they are tilted slightly upwards towards the center of the table if I had to guess these are probably used after the booster is well clear of the launch Mount so that it can begin to cool all of the metal surfaces that just got roasted seriously this is what it looks like after just seven engines this is gonna get crazy the other situation where I think it would be used would be in the event of an engine explosion during testing I think those explosions are much less damaging than they were in the past however in this footage from Justin Swartz you can see that the engine red is pretty well contained thanks to the new engine shielding upgrades for the Raptors we have really only seen the sprinkler system tested one time when one of lab Padres cameras happened to capture the unexpected test occurring in the background since then it has never really been used during any static fire tests on the orbital launch Mount even during this anomaly we never saw the fire suppression system engaged which was a bit surprising I'm not sure if this is because of the fact that it probably wouldn't have made much of a difference here or if it's because SpaceX truly didn't think this explosion was a possible outcome either way not going to dwell on that because as you will hopefully be able to tell they have been working overtime to make the necessary adjustments to prevent this from happening again since the day of booster 7's explosive flatulence onto the pad I have been watching closely to see what kind of measures SpaceX would take to address the cause of the incident and I gotta tell you I'm really liking most of the upgrades that we've been able to spot so far I will be discussing most of these on the next deep dive because understanding this water system will be an important building block for the next episode so how did SpaceX add this new water system without having to lay additional water lines between the olm and the tank farm well they started by deleting a section of pipe at the top of the Riser and then they replaced it with this branch that immediately turns up towards the bottom of the walkway they also installed two valves which would allow the flow to be switched from one direction to the other while our team waited around for something to be installed on the top of the second valve we noticed an unexpected pipe assembly being added between each of the six legs of the launch mount some of the initial thoughts were that this could be some sort of sparkler system similar to the one used for the space shuttle and SLS except here it would be burning away residual methane instead of hydrogen but given the direction of where this pipe is running to there's really only one option for what this is then we trace it back to the source this pipe runs just underneath the skirt of the launch Mount and then it disappears safe to say that it's going straight up with that being the case I knew this meant that each of these six nozzles were tapped into the nitrogen line on the Inside Edge of the launch mount these are the same pipes that I explained the function of near the end of this super deep dive from two months ago the nitrogen pipe I'm referring to is located right here just like the water pipe this one does a full loop around the table to form a circular manifold luckily from this view we can see where the supply pipe for this manifold is located it goes down at a 45 degree angle and then penetrates straight through to the other side looking at it from the opposite view we can see the pipe as it re-emerges and then makes a 90 degree turn up towards the walkway then another turn into the first blue valve just inches above the deck of the walking platform this is part of a distribution manifold made up of seven identical valves that control the flow of gases through this complicated network of pipes well ugly linked to all of this then I think it's probably a good idea for us to at least establish a basic understanding of what's going on here in the simplest terms what we are looking at is the pressurization system of the liquid methane and oxygen tanks of the super heavy booster the purpose of this is to deliver high pressure gas to both propellant tanks in order to keep them pressurized and increase structural stability essentially this system is what keeps the booster from collapsing under its own weight here's an example of pre-pressurization in action on Starship 24. this obviously isn't on the orbital launch Mount but it's still the same concept in this diagram that I posted on Twitter ages ago you can see the path that the oxygen and methane gas takes as it's routed through the smaller flex hoses and then up to the back of the booster quick disconnect when we look at the bqd plate you can see the locks and CH4 pre-press both labeled here I'm going to throw in this random clip of the pre-press lines being purged out of the bqd just so that you know what it looks like for later this isn't the only gaseous oxygen supply that goes to the bqd either if we go back to the distribution manifold we can see another pathway for the gas to take as well this pipe runs all the way to the other side of the massive insulated flex hoses for the liquid propellant Supply when it re-emerges on the other side it then turns upwards where it transitions to a smaller flex hose and then is connected to the back of the QD plate as well going back to the diagram we can see another source of oxygen labeled gox F over D below the locks pre-press dox is gaseous oxygen and F over d stands for fill and drain this is most likely the smaller line that we were just looking at a few seconds ago the gox fill drain is used to add gaseous oxygen to the copv tanks I believe SpaceX may also have another use for this that we haven't considered yet but that will make more sense later the important thing to note here when we go back to the diagram of the distribution manifold is that the yellow line for the methane gas really only has one path that it can take which is all the way up to the back of the QD well it does have one other option which you can see here this one is a bit confusing to me because if I understand this Plumbing correctly this is the valve that could allow the oxygen pre-pressed gas to directly combine with the methane which would create a pretty aggressive mixture and trust me don't nobody want to see that the fact that this is here tells me that it's possible that pre-pressurization is not accomplished using oxygen and methane gas at all and instead it might just be nitrogen on both sides well that would make this connection that is for some reason not double isolated using two valves instead of one make a lot more sense but if that's not the case then the reason this is here is because the gaseous oxygen supply has the ability to swap back and forth between oxygen and nitrogen but the methane Supply does not so in order to add nitrogen gas into the methane tank for initial pressurization after it's placed onto the launch Mount and to also neutralize all the methane inside of the tank before it's taken back off a crossover like this would be needed I just hope there's a check valve in there somewhere but I haven't been able to find one is the reason I'm explaining all this is because understanding everything that's connected together in this area is going to make some of the footage that we will review today a lot more intriguing because of all of this interconnectivity I assume that when the system was tested for the first time that SpaceX would need to monitor all the systems that could possibly be using this source of nitrogen at the same time there could be different combinations of these valves open at any given time based on where they are in the pre-launch OR static fire procedure at some point they might even need to have all of them open at the same time without any loss in pressure or flow rate so that means the vaporizers and gas distribution system that are supplied to nitrogen all have to respond to the changes in demand instantaneously so we will have to keep an eye out to see what systems are being tested together and maybe we can make a few educated guesses about how SpaceX truly intends to use this I'm sure by now a lot of you are wondering okay so why would SpaceX want to push massive amounts of nitrogen through the six nozzles that we mentioned a few minutes ago well uh to answer that we have to first finish discussing those water pipes where did we leave off again oh yeah so back when these nitrogen Jets were secured into place we noticed that there was a long bracket attached to it that had another nozzle mounted below the mounting bracket used to secure these two nozzles allows for them to be perfectly aligned so that the nitrogen jet is shooting straight into the mouth of the open water pipe the morning after the last of these nozzles and brackets were installed Starship gazer went out to the launch site and captured some of the first images of the new water supply lines now mounted on top of the open valve I called this the secondary valve up to this point but I'm going to refer to it as the primary from Huron because this system is far more important than the original one on the same day that gazer went out to the pad we were finally able to see what would end up being attached to the lower nozzle this was the first out of six pipes that would all Branch from off the main Supply and extend down towards the odd looking mounting setup these were temporarily held in place using a ratchet strap while the remaining pipe section was waiting to be lifted into position I was beginning to think this would take quite a while to build this manifold around the entire table if they had to lift all these pipe sections up one at a time and then weld them all together it could take quite a while to finish but it turns out SpaceX Engineers planned way ahead on that one later that same night we witnessed the first massive flex hoses being attached to the side of the launch Mount there are two hoses used to join the three nozzles going counterclockwise around the table the remaining three are in the clockwise Direction I can already hear some of you typing away in the comments saying that this looks kind of janky but I think the benefit of having these sagging flex hoses is that once they're filled with water for the first time they will never be completely empty ever again because ninety percent of all of the flex hose length is below the highest point of the manifold this allows the system to stay mostly primed at all times so with this installed I think a lot of folks were expecting the system to be used during the booster 7 static fire test but that didn't end up happening one reason for this could be that SpaceX just didn't want to test the system for the first time with the booster on the olm because they still needed to flush all of the foreign objects and debris from the newly installed pipes this way there is nothing but clean drinkable water being sprayed towards the engines it appears that's not the only thing they wanted to protect from the contaminated water flow because the night before the first test of the system SpaceX actually removed the nitrogen nozzles as you can see here in this before and after footage from Lab Padre huh those must be some pretty special nozzles later that same evening on September 21st we saw the first initial test of the system this actually started out with a flush of the original 12 spiral nozzles at their Max flow rate the spray pattern from these would probably reach the top deck of the launch Mount while there is no booster present a few minutes after this we saw the first ever test of the new water system as SpaceX flushed out the pipes by slowly ramping up the Flow To What We Believe might be its maximum designed rate as I mentioned before all of the flex hoses were empty at the start of this test so it took a while to finally fully Prime them all up you can see the nozzles turn on one at a time as the water finally reaches them keep in mind I usually speed up most of these clips pretty significantly so it took much longer than this in real time the interesting thing to note here is that the two nozzles closest to lab Padre's Rover 2 camera are also the furthest away from the supply source of the water because of this they are the last nozzles to start receiving water flow once the system was fully primed they turned it down to a much lower rate it might appear that it's actually turned off and just continuing to leak but I don't think so I believe what we're seeing here is the lowest flow rate possible out of this system assuming the water is being delivered at a near constant pressure the flow rate coming out of these nozzles would be fully controlled by these two valves on the main water supply this detail right here is one of the most important when it comes to determining whether or not this is a fire suppression system or an extremely underpowered water deluge each of these valves are opened and closed using pneumatic actuators which should be controlled using a solenoid valve somewhere it we should be able to find it just by following the pneumatic Supply pipes sure enough the control panel isn't too far away it's actually just directly above the valves we first noticed this when it was installed sometime at the beginning of September when we zoom in on the labels that were conveniently placed on the control panel we can see that the wording is just a little bit difficult to make out but with the help of our forensics team we were able to figure out which of these letters most likely fit into each of these blurry shadows and this is what we came up with Firex and detonation suppression underneath that it says Supply slash ISO panel we were able to find the term thyrex used in a few NASA Tech briefs like this one from 1967 which shows that it's actually just an abbreviation for fire extinguisher the term ISO refers to this pneumatic isolation valve which once manually pressed in will de-energize the entire system making it safe to work on this is something you would also enable if you wanted to make sure that this system does not get activated under any circumstances even if the testing procedure you're running accidentally commands for it to happen anyways now that we know the official designation of this Waterworks system maybe one of you in the comments will come up with a good acronym for it the good news is we can now say for sure that this is not a water dilute system so so thinking back to that label the Firex part is pretty straightforward just a bunch of water sprayed onto some flames right but that second part mentioning the detonation suppression system sounds pretty intense well I think it's finally time that we dig into that part a little bit so we can see how this system actually works now that we have all of this background info out of the way so looking at the mounting setup again it appears that the primary set of water nozzles are pointed up towards the arm of the bracket this means the water should never touch the engines and would instead bounce off the mounting bracket or the bottom of the skirt of the table these nozzles were reattached the morning after the water line had been purged out with all of the components now installed it was time to perform some integration tests on the full system it's finally time to see this detonation suppression system in action we can actually hear the nitrogen Jets activated before we're able to see anything this is the sound of nitrogen gas being diverted from the pre-pressurization manifold next to the bqd which travels underneath the walkway it then goes through the skirt into the center manifold and then out of those six jets that we've been talking about as you can probably tell it's super loud you can also see that very small amounts of water you're being trickled in as well allowing it to become visible now that this was verified to be working it was time to repeat the test and this time introduce more water into the mix this time around SpaceX started off with the Nitro Purge and then slowly opened up the valves for the water lines as soon as the water contacts the turbulent gas flow it instantly explodes into a fine Mist I'm not sure if velocity alone is causing this particular effect on the water or if there's something special about this nozzle that allows it to cause the maximum amount of breakup all I know is there is an extreme amount of force in that nitrogen jet I have a feeling some of you might be wondering why can't they just use compressed air here instead of nitrogen anticipating this I realized that the reason for this isn't so easy for me to explain in simple terms I tend to get rather wordy with my explanations if you haven't noticed using my background as a mechanical engineer I figured I would set up an experiment to demonstrate this concept just like that guy from practical engineering now remember don't try this at home [Music] always want to make sure you have your safety glasses [Music] foreign remember as long as you have your air you're good but then I remembered that all of my lowest grades when I was in school came from chemistry classes so in order to increase my own understanding on this topic before explaining it here to you today I hopped onto brilliant.org where they have thousands of lessons for math and science related topics with new exclusive content added monthly This truly is the best way to learn these stem Concepts thanks to the amazing interactive Hands-On lessons in my case this course about molecular choreography was extremely clutch when it came time to refresh my memory on how chemical interactions like the ones we are discussing here actually work on the molecular level that way I can better explain it to you in the simplest manner if you were a bit Rusty on these Concepts like me or just want to learn something new about the world around us then head over to brilliant.org CSI Starbase where you can find Advanced college level courses on a plethora of topics these are step-by-step lessons that are really easy to follow my favorite part about these lessons is that when you answer questions incorrectly the show explanation button doesn't just repeat what you already read it actually explains the concept again but in a completely different way for all of you parents out there this is also a great resource if you're trying to help your kids with their homework but you kind of need to figure it out yourself before you become the reason they get poor marks on the next assignment as an added bonus the first 200 of you to sign up will get 20 off brilliant's amazing annual premium subscription now that I've had process this this the reason why SpaceX wouldn't use compressed air in this situation is because of that keyword air even though they would still be able to achieve the same effect atomizing the water the problem is that air is roughly 21 oxygen so this means that while you're making great use of the water molecules inside of the fog to douse the flames you would simultaneously be giving the fire more of the thing that it wants the most in this situation which is more oxygen instead by using an inert gas like nitrogen which has a much larger molecule size than oxygen these Jets can actually displace oxygen under the table to the point where if you were standing there at the time of this test you would be at risk of asphyxiation from the lack of oxygen anything less than 12 oxygen concentration can begin to become dangerous for humans in order to extinguish most fires however you only need to drop the oxygen level down to about 15 to 18 percent this allows these types of systems to be used safely with people near the area but theoretically as long as you know there are no humans on site which would be the case during a spin Prime test static fire or launch you should be able to turn up the nitrogen flow as much as you want in order to choke the Flames out even quicker using nitrogen Jets alone wouldn't do the trick though because this launch Mount is so large that it would take forever to mix in with the air that is 20 meters above the ground where the bottom of the engine bells are this is where the water comes in as the nitrogen Jets hit the water it immediately sends it flying in every possible Direction which creates a large amount of wind not only can you see it but you can actually hear the wind as well if you listen closely [Music] this artificial wind machine helps the nitrogen spread out more evenly in every direction which drastically increases its effectiveness so now we know the area underneath the launch Mount can be quickly neutralized of explosive gas mixtures and any residual fires down there should be extinguished pretty quickly and it can be done without using a massive amount of water which would require a retention pond on site like the second Starship launch Mount at the Kennedy Space Center instead all they need is this little catch Basin that was added in a few months ago and pretty much all the water from the launch pad will end up in there instead of going off into the wetlands after reviewing all five hours of footage I was able to notice at least four different testing configurations for the fire and detonation suppression system there are several ways I can imagine these four operating modes being used I'm expecting we might see it during every static fire and for the first orbital flight test even though this may quickly be proven wrong a few weeks from now I'm going to give everyone a few possible scenarios to consider based on the different configurations then I want you all to take some time to mull it over and then come back and let me know what you think in the comments all right first up it appears that at some point SpaceX will be operating this with nitrogen Jets turned off and water at the maximum rate this causes the agua to hit the bottom of the mounting bracket and fall to the ground like a massive rainstorm I suppose this could be used to drench the pad before engine ignition and it might also help to mitigate some of the dust during static fires that would be nice but I think this rainstorm could also be used for cooling down the bottom of the launch Mount and probably the legs as well and I'm sure the concrete will also be incredibly hot so this will help to bring those temps down much faster next we have water supply off with the nitrogen Jets on full blast it's possible this could be used to disperse all of the gases that come out of the Raptor engines during spin Prime tests this would reduce the likelihood of gases staying built up under the table for this long or better yet maybe this can allow SpaceX to remove the temporary Raptor Shield diversion system I think that might be on the top of the list right now when it comes to being ready for the first orbital launch attempt scenario number three we have water and nitrogen both turned up to their maximum flow rate causing a gigantic Vortex of mist well as long as SpaceX isn't worried about the engine Bells getting wet by this purified drinking water I think this would be a good use during the static fire especially ones with 33 engines it wouldn't do much for sound dampening but it could possibly reduce the need for it in the first place let's look at this absolutely ridiculous footage from cosmic perspective showing the seven inject standifier at 900 frames per second and then hopefully you will be able to see what I'm talking about here this is the spin-up process of a Raptor 2 engine at the speed we are watching it takes approximately 30 seconds after the first puff of vapors is ejected from the main combustion chamber until the actual ignition occurs I could be wrong here but what I think I'm seeing is a huge puff of cold oxygen being pushed out of the bottom of the engine as the lock side is basically performing a spin Prime you will notice this end abruptly as hot methane gas begins to enter the main combustion chamber you can literally see the methane in the air even though it's kind of invisible the methane Cloud instantly begins forcing The Cloud of oxygen down to the ground forming a MOX sandwich that's methane and oxygen mixed together for those who are unfamiliar with the term as the engine ignites and the Flames from the exhaust begin to reach down towards the ground you might notice that the front of this flame looks like an arrowhead pointing straight down into the ground that first ball of flame hits the ground with an incredible amount of force [Music] foreign ball comes out of the next engine which is mostly hidden behind the leg in the middle even with the huge pillar in the way you can see the pressure wave from the ball of flame that is traveling to the ground it is so strong it even deflects the exhaust of the center engine for a brief moment when the remaining five engines turn on it's a bit difficult to see them in the background thanks to Ryan Hansen space we can get a nice visualization of what is happening back there as you can see once the first two engines ignite there is a considerable delay until the next one fires immediately after the third engine however the booster appears to enter rapid fire mode the reason for this initial delay is because the booster is actually skipping over about 20 engines in the ignition sequence now let's watch it again except this time pay attention to the frosty pipe just below the walkway up here look what happens to the ice that has accumulated on this engine shell pipe as each ball of energy hits the ground wow that is incredible I could play this back to back all day but you also go watch the original by Cosmic perspective because this is something else so anyways the point I'm trying to make here is I think that these secondary explosions could use some detonation suppression you know what I mean I believe that this system while running on full blast will completely eliminate that secondary explosion by displacing The Cloud of oxygen long before the wave of methane gas has a chance to collide with it finally last but not least is the scenario I'm most curious about this one came as a surprise to me and I'm sure it caught Chief off guard as well you can see here that in between these two shots the booster cutie decided to make an appearance as soon as I noticed this on lab Padres Rover 2 camera I was glued to the screen I had a feeling I was about to witness something extremely important and I was not disappointed what you are seeing here is the pre-president happening at the same time as the nitrogen Purge remember when I said they would need to balance all these systems that would be used together well let's look at this from the front because it gets even more interesting thanks to this perfect angle from Chief we can see that not only is this the pre-press venting but it's also the gox fill drain port on the bqd and the six nozzles below the table all at the same time okay if you can't tell this one got me really excited for close to two and a half hours the system was tested repeatedly you could really tell that SpaceX was trying to get the system dialed in and balanced they repeatedly increased and decreased the flow coming out of the bqd ports and the sixth detonation suppression system nozzles at times the flow has increased so much that the entire distribution manifold ended up frosting over the nozzles were noticeably frosted as well there were so many combinations of events that happened in here that truthfully I'm still analyzing most of them the thing is there aren't a lot of situations I can come up with where all three of these would need to be running at the same time unless well there's a chance this might have something to do with this tweet I sent out a few months ago asking Elon about an important feature of the launch Mount that I thought would be a good idea to have been on the lookout for signs that it was real ever since he responded could this be it unfortunately we aren't going to be able to get into this part of the investigation today there's an entire Deep dive into the other new changes on the orbital launch Mount that will have to come first I'm pretty sure all of these things are interrelated in particular I'm talking about the DraStic upgrade and blast shielding to the orbital launch Mount that most of you are probably not even aware of is occurring Brian Hansen space has been working hard to help us understand what the heck has been going on inside of the launch Mount over the last few days we will also discuss the changes to the Raptor chill process for the booster which took effect after that explosion a few months ago in the process I'll teach you all a cool trick to accurately predict which engines are going to be tested during a static fire 30 minutes before it actually happens if you learned something that you didn't know before today then do me a favor and hit
