What Happened In The Fog At Boca Chica - What Caused SpaceX's Latest Prototype To Explode?

I admit, I'm stumped as to what might have gone wrong, because it looked the tank exploded at altitude rather than simply suffering a pressure failure in the tank. In previous RUD's the Starship tanks haven't shattered into small pieces except until after they hit the ground so whatever caused this was more violent than a simple pressure failure and might be an explosion inside the tank. I hope we find out more.

  • Wondering if there is a complication when you have a tank failure in the belly flop with the extra dynamics of falling sideways at more than a few mps. I can see an inflight breakup being more dramatic than seen on SN10 because of the airspeed, once the tanks lose rigidity the stainless is going to rip apart under load fairly quickly.

  • well, why you should know what happened? if you work for their company, then you would know ... they can decide freely what they do share to the public and what they don't. Sure, I'd like to know fore SURE what has happened, like literally millions of folks, too.. ^^ xD ps: X has even some repositories on GitHub (reads: open-source). didn't know for years... ^^ I think the mega big public interest is both, a cure, but also a curse .... if nobody looks or hears (measurements), there literally (I love this w0rd!) anything can and will (have) happen(ed).... Think along with Schrödinger's, not about it 🐈❣️ -- IF you (yes, you reading this and the others() DO_MEASURE_THE_CAT THEN you MAY HAVE killed the cat in the final quantum-collaps to a finite, known state....

  • What kind of HOTAS setup are you running there, Scott? ;) EDIT: I have a Thrustmaster Warthog and it is, indeed, a hog. I love it to death and the switches are so solid and the controls feel so nice in my hands, but it is a bear to set up and configure. Anyway, I was just curious. I'm not up on my higher end joysticks because I haven't flown anything in a sim/game for a while. SIt's just nice to keep up on joystick tech. ;) Too bad you won't see this comment or have the time to read it if you do. Anyway, I love your content. Take care! :) EDIT2: Just in case anyone else stumbles upon this comment in the future... I did some searching and I'm _pretty_ sure that what Scott is using is a Logitech X52 Professional H.O.T.A.S. (joystick and throttle) setup. One can be had for a cool 257 U.S. Freedom Bucks. I was lucky to find my Warthog on sale for $313 a few years ago, but it looks like they've raised the price quite a big. Whew.

  • Elon says he doesn't like a lot of parts. Elon says he has robotaxis, level 5 autonomy, functioning brain chips that can cure diseases, semi trucks, and is going to colonize Mars. All these things are true only in a way a loving mother could see them. Oh, sweetie, you're doing so great! If your predictive model relies primarily on something things Elon says it's not one that has served you well so far.

  • I suppose if you wanted people to see your rocket you wouldn't want to launch it in a thick fog bank. Also if you wanted to gather visual data yourself. I like Elon's style of engineering without all the fuss of predictive modeling and data. I will be on the edge of my seat when the first people get on that thing after they finally get it right. They did get it right this time, right guys?..

  • I'm kinda getting a Mercury-Atlas 1 vibe from this: where the rocket was launched on an overcast/rainy day and the guys at Cape Canaveral couldn't see what the hell was going on. I'm going to say that it was probably a different failure mode for SN11, but the sight issue just reminded me of it.

  • I am curious about the possibility that they may not be telling us the truth in regards to the flight termination system. At some point in time, it seems important to find out how many small pieces and how far they would fly in the event of an intentional RUD. Maybe they thought that with all the upgrades in SN15, they figured that SN11 was somewhat dispensable, and they “had their finger on the button” so to speak, and when things started going south, they decided to test the FTS. It would make sense for them to deny this, at least initially, in case they caused damage or injury by exploding it. Anyway- I think we are all on the edge of our seats to find out if the 100 upgrades on SN15 will fix all previous issues and make it the first flawless prototype. Good luck on your Dear Moon aspirations!!!

  • To me, it looks like the explosion mus have happened at the upper centre of the rocket. Can't be lower, because then, the engines wouldn't lay so close to each other. Also, tge bottom skirt, the nosecone and the engines are the only recogniseable parts, so the explosion must've been between them.

    • the leak wouldnt have built up propellant, it was on fire and would have been burning it off. musky stated that this fire was part of the cause though! it burned up some avionics which lead to (from what i can decipher, to me most of it is just technobabble) an over pressure event in one of the turbopumps which became the primary source of the explosion.

  • Could be it a structural failure with the tank? What I mean is, is it possible that when the engines fired that the force of the and engines and the aerodynamics of the nose caused it to ‘fold’ in on itself thus creating a mixture and large explosion, or maybe just the energy from it folding in half could cause a large debris field.

  • Here's what I think could be an important question for Space X. They spend Millions of dollars on each SN Rocket and then it explodes during a test to make it reusable. They are spending over a Billion dollars without recouping a cent. Of course, they are getting close to reusability but have many milestones yet to achieve. All this while building their launch facility and production facility. I wonder if they would consider trying to make some money in a "Disposable launch vehicle"? Soon, they should be able to launch a payload with Starship. They could plan for it's demise. Then, after the payload is launched, they get paid, and then continue to test the vehicle to develop its reusable capabilities. At least they'd get some return out of the development process they are not getting now!

  • What is the possibility that the centripetal forces of going from horizontal to vertical while winding the engines up, and those pumps are essentially high speed centrifuges, what kind of un-resolved torque could be the problem they are having with the flip-landings? Perhaps a need to go to vertical sooner, just on flaps and thrusters and Then start engines while in the upright position, thus no added engine pump torque and RUD situations?

    Chuck SweetChuck Sweet8 päivää sitten
  • Scott - a thought. It seems that the main issue is the poor fuel/oxygen feed to the motors. What if the tanks had a baffle from the bottom (being the bottom when the spacecraft is falling in its wings) sufficiently up the tank so that there was enough fuel aft of it to run the landing burn. So, say the baffle was 10 metres up (as in towards the nosecone), and say covered half to 3/4 of the tank area, also the fuel outlet, instead of being in the centre of the tank is at the bottom edge. When in vertical flight, the fuel would run from the full tanks to the engines as normal. When the rocket flips to a horizontal position the fuel to the aft of the baffle would fill the tanks to the level of the top of the baffle, and the remainder would slosh around the tank towards the nose. When starting the motors in a horizontal position, there would be enough fuel to keep them happy (especially if the exit was "below" the centre of the tank), and if the burn were to continue to landing, the remaining fuel would flow down from above the baffle to keep the motors going. This seems to me to be a relatively simple engineering problem to be solved, and does not involve extra small tanks, helium pressure etc.. I should like to send a sketch if you are interested. What do you think?

  • The weather radar image of SN11 is incorrect, Boca Chica is south of Port Isabel. That little lagoon just under Port Isabel has a peninsula jutting out from the coast inland in a slightly southward direction, that's Boca Chica. There's a tiny little blue dot of reflectivity there which is probably from the high bay because it's about 2 miles east of the launch site.

Elon needs 6 degree of freedom accelerometers to measure vibrations and resonances ... and accurate FEA models tweaked by measured results to adequately simulate this. I suggest high speed close up cameras to measure vibration movement of reference dots on 100 critical parts of the Raptor. Then verify the Finite Element Analysis model of the Raptor matches the measurements.

I know they have to evacuate a small village every time they make a test and that costs a lot but i wonder if the investigation would now cost much more than a scrub. I also guess the FAA doesn't care if the day was foggy, they require the same minimum safety guarantees. So maybe no more foggy launches for tests?

There's probably an employee that's sabotages the missions..... Or maybe the engineers just aren't doing their jobs.... Something needs to change because this is happening to many times. If there is a person in the company that's perhaps not installing components correctly needs to be found and arrested.

Let the rig slosh around during the various stages of flight without sending up a full on starship? Something is clearly happening with the engines when they are being flipped around which they don't like? They could do lots of shorter manoeuvres on this static rig to maybe iron out some of the problems without blowing up expensive ships every time?

      Doug InOrlandoDoug InOrlando9 päivää sitten
    • ​@Bushcraft1974 Yes. The whole idea of fuel feed is based on gravity. If no gravity, no feed, just some weightless floating fuel in there. So Archimedes tells us that liquid will seek its lowest level when in the influence of gravity. So, if the spaceship is to be horizontal the side of the fuel tank needs to be sloped in the direction where the pickup is, i.e. the bottom. A cone shape to get a symmetrical affect = / \. Or a semi-cone shape if just one side = / |. These are the basics of fluid dynamics. There is no magic that will make it work any other way. Autogenous pressure is just a fancy word which means nothing with respect to this problem. I'm thinking a freshly graduated Mechanical Engineer could design this in a couple of hours. Who knows what SpaceX problem is ..

      Thermo *Thermo *9 päivää sitten
    • @Thermo * Yes exactly my point! The newness of what Starship is trying to do has led to forces being put on the engines and tanks but to my small knowledge they never tested all that sloshing around before the first flip test...was that SN9? If they have done these static tests i will concede but it seems like they are trying to run before learning to walk? I don't like ship after ship crashing for what is seemingly the same problem......the engines don't like lighting after the tanks have been horizontal?

      Bushcraft1974Bushcraft19749 päivää sitten
    • They really need a static test rig with just tanks that they use. Don't need engines. There is only one problem, only one. When horizontal, the bottom of the tank is now the side of the tank but the pipe inlet is still on the bottom. The bottom of the tank is funnel shaped. That can't happen on the side of the tank. So the feed of fuel changes source based on the rockets position. Unfortunately, the tank doesn't change shape to compensate. Ideally, you'd want an internal tank shape to be something like this / | so when rotated 90 degree's to the left the fuel will roll down hill to the bottom where the pickup is. You'd still need anti-slosh baffles. And if there is a test stand, the design could be verified. No launch is going to be consistently successful until they work this out. Sometimes it may work but it would be by luck. Doesn't matter about SN15 - SNXX, if this is not fixed now, why continue, it's a waste of time !
