back to article SpaceX's 'Days Since Starship Exploded' counter made it to 48. It's back to zero again now

SpaceX's latest attempt to fly its Starship has again ended in a rapid unscheduled disassembly. The Thursday mission, the eighth flight of the vehicle NASA has contracted to use for 2027 demo of a crewed Moon landing, aimed to nail an hour-long transatmospheric journey to the Indian Ocean that the previous launch could not …

    "Oh what irony it would be if SpaceX’s boss Elon Musk needs to renegotiation the company’s NASA contract to reflect increased costs, given his side hustle as leader of the public-expenditure-slashing Department of Government Efficiency."

    SpaceX need parts that are imported from from places that will have tariffs imposed, eg, Europe.

    So NASA will eventually have to foot the bill, one way or another. On the up side, the Unelected VP can blame high costs of unamerican stuff as the reason the US will be unable to colonize Mars.

        Maybe fewer customers

        Musk retweeted someone who suggested Mexican telecom billionaire Carlos Slim has drug connections, and Slim cancelled a $7 billion contract with SpaceX and will remove them from consideration for $22 billion of upcoming contracts. He said he will go to China and Europe instead. FAFO FTW!

        So Musk's ketamine fueled craziness is costing him billions even outside of the "I will never consider a Tesla because Musk is a nazi" that is cratering Tesla sales in the US and Europe.

        Here's hoping he loses everything. I know that's impossible for someone worth hundreds of billions, but if he fell down to being worth just "billions" or even "tens of billions" he will feel like he's gone bankrupt and it will be beautiful to see. And Trump would probably distance himself from Musk just because he wouldn't want his taint of failure to be alongside him everywhere he goes. And that would cost Musk's wealth to drop even further because a lot of Tesla's stock price is based on him getting super favorable treatment for stuff like deploying self driving taxis plus favorable treatment for SpaceX, but if he's out of the Trump buddy club then that stock boost disappears.

          Musk lives on loans using his shares as collateral, to ensure he doesn't pay any tax. If the banks decide those shares aren't worth anything then they'll call in the debts. That will force him to sell off other shares, which will reduce their value and thus other loans get called in.

          With luck, the resultant spiral would leave him with merely a couple of million, at which point he'll be bankrupt within a month because he's got absolutely no idea how to budget.

Its clearly not worth anything like that much on its fundamentals, it is basically a "hope and dream" stock for people betting on robotaxis. I'm hoping he's forced to announce a delay in their planning summer deployment in Austin - that would really tank the stock and make me a lot of money (I bought $10K worth of $300 July puts around the new year, basically betting that the post-election Tesla gains were unsustainable and Musk would wear out his welcome in the White House, last I checked that investment is now worth about $35K)

            I don't see why that argument keeps being passed around. Loans must be repaid, so at some point money that's been earned from somewhere must get used to pay the loans back.

            The game is usually about borrowing money, which can be cheap, and use it to earn more money while keeping one's own money held in reserve. The cheap cost of money comes down to having enough of your own and some serious collateral that a low interest rate can be negotiated. If you wait until you really need a pile of cash to keep the doors open or to move fast on an opportunity, the bankers are far less accommodating.

      Blowing up Starships is relatively cheap. This one was intended to blow up. The problem for SpaceX is it blew up before testing the heat shield. Starship HLS is a tiny firm fixed price contract compared to the money lost to Musk's rapid fire government policy.

        Sorry, yes the root root cause was the harmonic response, which caused leaks, the leaks caused overpressure, and the overpressure caused fire and explosion.

        So my crude understanding is that they did the rocketeering equivalent of sticking some duct tape over the bits that had leaked to reduce the likelihood of a leak, and put something in place to vent the overpressure to reduce the chance of fire and explosion. Clearly neither worked.

        So they need to stop the leaks, and they need to stop it by sorting out the harmonic response, not bodging round the edges.

          Being old I remember the Apollo mission astronauts mentioning what became known as the pogo effect - I think that was the effect of a small change in fuel feed rate being amplified into a shift in position of the whole rocket.

          Am I right in thinking this harmonic response is some part of the spacecraft resonating with some component of the general vibration from the engines? Damping the resonance so the response is just flat sounds a sensible move to me. I suppose that would need redesign of assemblies in various parts of the spacecraft?

        Re: Bodge job

        There is no evidence released that says the cause of the incident was an engine failure - changing an engine is a red herring.

        The issue (harmonic response) caused failure of the fuel system somewhere - downcomer joints, engine manifolds, even tank structure itself and leakage into the attic. The problem is that they may have cured the apparent issue (as demonstrated during the extended static fire) but if the fuel itself acts as a dampener (eg for the main downcomer) then the fuel level may mitigate the problem until it reaches a critical level or be in a certain attitude.

        The only way they could even try to stimulate this issue in testing is a full tank test firing, but on a test stand this may not demonstrate the issue (see comments about pogo earlier) - for a start the dynamic forces are different and the vehicle attitude is wrong ... So, unless the fault is a result of minimisation which can be found, or a basic design flaw with the triple downcomer pipe structure (which I believe was used in the last flight and this) the only way to test it is to fly it ...

          "The problem is that they may have cured the apparent issue (as demonstrated during the extended static fire)"

          The test may have shown up a problem they thought they had but not been adequate for the actual problem. It might be stresses from moving the whole thing around on-site and the static fire just primed the failure mode which may not have happened had they not conducted the test. What they might need to do is an extended and heavily instrumented test based on flight data and then take the whole thing to bits and examine every part very carefully.

          They're getting pretty good at catching boosters, which is good to see - and will stand them in good stead when they try to catch a ship as well.

          The early failure absolutely limited the data they could gather, but it didn't mean they gathered none.

            "They're getting pretty good at catching boosters, which is good to see"

            I don't see why. It's moving the catch point from landing legs to landing "armpits". They land the F9 all the time with very good accuracy and might even have to vary the aiming point so they don't just drill a hole through the concrete. Catching further up on a couple of pins removes the mass of the landing gear, but it requires more things to work precisely for it to be successful. If they catch a booster and there's damage to the site, they will have to ditch the upper stage. If they were to crash the booster on a landing pad, there could be enough time for the fires to go out and tractors brought in to drag the wreckage out of the way so the upper stage can be landed. Having two towers is ok, but if they crash a booster into the very close tank farm, the whole site is offline and the upper stage is toast since they won't have that long of a window to bring it back down due to propellant boil-off.

            SpaceX really needs a reusable Starship to support their Starlink program. The world doesn't really need a 100t+ launch vehicle very badly. When one is needed, it's for a very specific mission so a generic vehicle is fraught with compromise.

        Re: Bodge job

        "The long term fix is to switch to Raptor 3 which has fewer places to leak. "

        The downside is it being really hard to inspect a 3D printed engine/investment cast. If a modification is needed, the whole engine and possible a whole run becomes scrap. This system is supposed to be reusable so being able to quickly inspect the engines and do any refurbishment is key or the engines need to go back to the shop for a complete tear down and comprehensive scan.

        The upside is that once the engine is completely dialed in that it can be easier to crank them out if they can be QC'd properly. I've been through this and another compromise is that, so far, it's not easier to use different metals. Copper for the combustion chamber gives really good thermal conductivity and higher operating temperatures, but it's heavy. Aluminum has reduced thermal conductivity and temp tolerance compared to copper, but it's much much lighter. The universe was poorly designed so there isn't a one-size-fits-all material for rocket engines that has the melting temp of Nickel, the heat conduction of diamond and the density of Beryllium. If there was, it would be impossible to use with additive processes (Murphy, et al).

      Re: Bodge job

      "From what I read, they didn't focus particularly on fixing the root cause (the leaks) but tried to make it such that if the leaks happened again it wouldn't cause an explosion."

      The leaks causing a fire is an issue, but it would be more probable that something let go causing engines to flame out which led to tumbling, which led to more bad things. There was a call out on Flight 8 of "FTS Safe(d)" that seemed to indicate that the Flight Termination System has previously been turned off. That makes sense since one wouldn't want it going off on accident. It also tells whoever might have the Big Red Button on their screen that it's a manual thing at that stage of flight. If it was activated, it took far too long. At the very least, it would have made sense to shut the whole thing down if they wanted time to clear the islands before blowing it up.

      Turbo pumps are notoriously twitchy and ice forming in the cryo tanks has been a concern. It has been pointed out on the control room feed that there was an explosion in the engine bay just prior to loss of signal that an operator was reviewing. Too bad the engine bay view wasn't on the live feed when that happened. It wouldn't be a stretch to believe that plumbing came unplumbed which caused engines to starve and go out and a good mix finally came together and went off bang. If they blame it on V2 of the Raptor, any claim of V3 being better has yet to be substantiated. The V2's are coming out of test approved for flight so they can't be complete shit.

    Some of the six motors stopped and the thrust must have become too far off centre line and caused the thing to start rotating. Seems very similar to the last flight. Guessing causing extreme vibration or oscillation breaking stuff in the back, something that can only be really tested by flying at 15000 km/h in near vacuum.

      "causing extreme vibration or oscillation breaking stuff in the back, something that can only be really tested by flying at 15000 km/h in near vacuum"

      You don't need to test this. If it happens, it breaks.

      The solution is for the motors to not cut out.

      1. Richard 12 Silver badge

        The engines cut out because they self-dismantled.

        In the video there's a very visible burn-through on the engine bell that ceased first. It basically blowtorched itself in half, along with the three smaller engines in the middle.

        Why did it do that?

        A broken pipe would reduce flow to the engine as the liquid is going elsewhere, and they're cooled by their own propellant so reduced flow reduces cooling.

        The most probable cause is that it's exactly the same fault as before - the pipes vibrated themselves to bits.

    Raptor vacuum nozzle failure

    Looks like this may have been down to a Raptor vacuum nozzle failure - have a look at ~47 minutes into the Space X stream and you can see an orange glow round what appears to be a slot cut into the end of the Raptor vacuum at the bottom left of the screen. There are reports that this engine can be seen exploding on a screen in the background on the control centre video feeds, but I've not been able to verify that yet.

    It is possible that this engine was damaged during the extended static fire that was used to verify that the plumbing and engine profile changes had fixed the harmonic issues. Testing vacuum engines at sea level is hard as flow separation within the expansion nozzle can cause the nozzle to fail - this is mitigated this by putting a supporting ring round the end when test firing, but that doesn't elliminate all of the stresses.

    It would be bad luck if it turns out that testing to prove that a fix is valid caused the vehicle to be lost.

    Edited to add:

    That engine was the first one to show as shut down on the telemetry feed. It appears as if its failure then took out the centre three engines (not quite all at the same time). Loss of control was inevitable once they were out as they are the only ones that have the thrust vector control that's needed for steering, and the two remaining vacuum engines would have been producing a significant turning moment due to unsymmetrical thrust.

      I was watching the NSF feed and they spotted that, and reckoned it was a burn through on that nozzle. But they also reckoned there may have been a fire given there was some possible flame visible around the camera looking at the engines. That feed was cut pretty abruptly just before the UED and Starship developing a bad attitude. Apparently the previous flight turned into more physics than expected due to a fire in the 'attic' between the bottom of the fuel tank and the engines.

      I can't help but wonder if the hot staging is maybe a lil too violent. There were some good images of the flame jetting out around the staging ring before stage seperation, so how much of that force & fire ends up being directed up into Starship's engine bay.

        Re: Raptor vacuum nozzle failure

        "I can't help but wonder if the hot staging is maybe a lil too violent."

        To need to do the hot staging gives the impression that they are having to push every component of the system and don't have any margin. Once out of the atmosphere, Newton takes over and a body in motion stays in motion at a constant velocity in the same direction. If the booster pushes the upper stage away to disconnect and let it maneuver to come back. they Starship engines can start any time with no loss of momentum. With amateur rockets, we will hot stage to maintain acceleration as when the booster motor dies out, the rocket really starts decelerating so it makes sense to start further stages early depending on the flight profile desired.

      There are vacuum test chambers for rocket engines. I was able to tour one at the Air Force Research Lab at Edwards Air Force Base in California where they did a lot of the work on the F1 engines for the Saturn V rocket. We went up to Rocket Ridge as well and I got to stand on the stand where those engines were tested. No photos were permitted and the official photographer never got around to getting any to us. The bum. An amazing day.

      The vacuum system builds up a whole bunch of steam and a rocket engine is run in a chamber that's "blown down" well below atmospheric pressure. Maybe there's information on how much of that can be done, but it's an impressively large facility.

    Harmonics

    They claim "harmonics" (vibrations?) did in the Starship, rupturing propellant lines and starting an explosion which knocked out the engines. I'm somewhat surprised this keeps happening since none of this seemed to be a problem on the first flights. The modifications they've made haven't had the desired effect. They're churning out so many Starships that the quality of workmanship may also be falling and contributing to the increased failure rate. I hope they can get this sorted soon.

    IMHO this is a huge setback since they haven't made any progress during the last three flights. A lot of work has to be done before they can even attempt a trip to the Moon and an uncrewed landing. And 2030 is rapidly closing in. The Chinese seem to be on track for a crewed landing at that time and NASA (and U.S. Congress) are adamant the U.S. should beat them to it. If things don't improve quickly it may become a close call.

      Re: Harmonics

      "I'm somewhat surprised this keeps happening since none of this seemed to be a problem on the first flights."

      Well, the first flight went really badly, as expected. Lots of significant changes are being made with each flight. My take is they aren't putting the time and effort into getting things right before they commit to hardware. Virgin Galactic may be completely washed up at this point since they committed to the airframe design before getting the rocket motor all worked out and then tried like the dickens to get the motor to work in the space allocated and the parameters required. It would have been better to spend the time to get the motor all sorted and then finish details on the airframe. Sort of like the A-10 starting with the big bang stick and wrapping the plane around that while added lots of mounts to load on even more fun for every flight.

    Range Safety

    Every change that Starship was deliberately exploded. If the engines had failed and they lost control, one of the jobs of the Range Safety Officer is to remotely detonate the vehicle - it's safer for smaller fragments to disperse than it is for a massive ship coming down in one place.

    You can see in the Challenger videos for example (and it wasn't heavily publicised at the time) but the RSO remotely detonated the SRBs after the explosion.

    1. Excused Boots Silver badge

      Re: Range Safety

      I didn’t see it live but watching the subsequent video, I’m sure that a second or so after the engine shutdown and loss of attitude control, there was a callout “xyz (wasn’t entirely audible) is safe’ed’. Now the only thing I know of that could fit is FTS (Flight Termination System - ie self destruct). So assuming that ‘safe’ed’ means deactivated* then was the destruction of the vehicle not down to the FTS but simple dynamic stress?

      * and, I’m making a massive assumption, I’m sure there are commutards on here far more knowledgable than me on this, so more than happy to be corrected.

      1. FeepingCreature

          Scott Manley dropped a video about this and reckoned it was a callout, so staff pointing out that FTS was currently safe, and maybe it should be re-armed. He also speculated that it may have started breaking up due to the stress. It was interesting watching the fuel levels change as the ship tumbled, and there must be a fair amount of kinetic energy from that sloshing from one end of a tank to the other.

            That seems to demonstrate that there's some sort of fuel level sensor being used and not just a mathematical model driving the display. If that's always been the case, it brings into question whether they ever really did a propellant transfer from the header tank to the main tank.

      Re: Range Safety

      It's hard to get reports out of it, I'm reading more and more that suggest it may have been auto-destructed once it sensed it was beyond flight limits. But from what I can tell, the last attempt self destructed:

      https://www.spacex.com/updates/#flight-7-report

      "Contact with Starship was lost prior to triggering any destruct rules for its Autonomous Flight Safety System, which was fully healthy when communication was lost. The vehicle was observed to break apart approximately three minutes after loss of contact during descent. Post-flight analysis indicates that the safety system did trigger autonomously, and breakup occurred within Flight Termination System expectations."

    3. MachDiamond Silver badge

      Re: Range Safety

      "If the engines had failed and they lost control, one of the jobs of the Range Safety Officer is to remotely detonate the vehicle"

      And, the RSO should not need to get any approval to do that. It can be prudent in some instances to hold off on blowing it up, but shutting off the motors and letting it get clear of some islands first and then create a load of multi-colored rain. What to do when depends on the circumstances. One big lump might be preferred if the splash down point is away from everything rather than a wide area of smaller chunks.

      I've stood by with a Big Red Button before. In our case, the rocket wouldn't be blown up, but a lot of valves would be immediately put into their default state which would cut pressure and vent tanks. We held planning meetings on where, when, who, how. For most flights, there would be two of us with kill-switches looking on from opposite sides. The flight director could also call out dropping the vehicle if he could see that control was lost and the rocket didn't do it automatically.

      There were two "fences" for the landers I worked on. Breaching the first fence should have had the rocket land immediately and violating the second fence would kill the engine and vent the tanks. Humans were in the loop in case the software wasn't right. I can recall only one time where the first fence was violated and that was due to a programming error by the GN&C engineer and led to a new and mandatory flight profile checklist. The lander rose up 50cm and landed itself. Very not good.
