    Successful Raptor on-orbit relight demo! That should clear the next flight to go to orbit and deploy operational satellites! Big milestone for the program.

    And the ship landing was so soft it didn't even explode! That's never happened before. And it's still connected to Starlink too. The ship's cameras are still working underwater! I wonder if they will be able to recover it intact?

    We're getting some great views of the heat shield post-reentry. That's great data for the heat shield team. The heat shield is the biggest remaining question mark in the whole program. Reflight without heat shield refurbishment will be required for the whole architecture to work, and it's never been done before. None of the heat shields so far looked reusable without refurbishment, including this one.

      They have a much biglier support vessel this time, almost 300ft long IIRC. So maybe they can recover it?
      • stinkbeetle 4 hours ago
        It might be possible. Allegedly they had previously asked the Australian government about towing the ship back to a port.

        Marine recovery can be much more difficult than it might seem though. Towing this nearly 200ft structure weighing a decent fraction of the weight of the boat that is not designed to be seaworthy, potentially full of explosive gasses and that could rapidly start breaking up and taking on water, nearly 300 nautical miles back to shore, would be quite difficult and dangerous. I would be impressed if they ever do it.

        • chasd00 4 hours ago
          yeah it's suppose to tip over, explode and sink. Not sure what they're going to do with it now. If some other country comes in and salvages intact Raptor3, flight computers, and all the other ITAR regulated tech SpaceX may have a big problem. SpaceX will probably ask the airforce to gift them a jdam delivery or something.
          • aejm 4 hours ago
            They can relatively easily sink it, and in fact are required to be able to in order to get their US FAA launch license. As part of the environmental assessment specifically, but I could be wrong on that. For those curious, they have recovery teams on sight who can essentially shoot it to further puncture the hull or attach explosives even. They have experience with their Starship boosters not sinking off the coast of Texas and floating into Mexican waters.

      > That should clear the next flight to go to orbit and deploy operational satellites!

      Mid-stream they said they were deploying 20 real V3 Starlink satellites.

      At the end of the stream the said all 20 had checked out as well.

      • FLHerne 5 hours ago
        They were real satellites but deployed on the suborbital trajectory of this flight, so will have burned up over the Indian ocean about the time that the ship re-entered.

        The goal was to get about 20 minutes of testing the new satellites in space, not for them to have any chance of becoming operational.

        Starship hasn't been entering a full orbit so far because it would be really bad if the relight burn did fail - chunks of ship would rain down a few days/weeks later on some random area anywhere within 27° of the equator. On a much smaller scale this has been an internationally embarrassing problem for China's LM-5.

      • everfrustrated 5 hours ago
        They need to be in orbit to deploy the satellites into a useful orbit. These ones only lasted for 20 minutes before breaking up.

          I hope they watch some of these, because movies are full of disappointing rocket scenes that are so many orders of magnitude away from the real thing that it's like representing a skyscraper with a treehouse. There is considerable room for reality to inspire fiction a bit more on this front.

      What about this one looks not reusable without refurbishment?

      To my eye it’s by far the best we’ve seen, no burn through on flaps, etc

      • modeless 3 hours ago
        Lots of missing tiles still. Best case is it's all infant mortality and replacing just those tiles will result in a durable heat shield for many more flights. Worst case is every flight loses that many tiles and the ablative underneath can't be reflown until replacement.

        I wouldn't be surprised if we end up seeing a heat shield refurbishment attachment to the launch tower that allows technicians to access the side of the ship to patch up between flights without leaving the pad. They're going to need some kind of solution for the many back-to-back HLS refueling flights.

        • ceejayoz 3 hours ago
          They've intentionally flown a number of times with missing heat tiles in sensitive spots, and many of those don't have the ablative coating. One of the benefits of steel over aluminium.
        • testing22321 3 hours ago
          Musk tweet:

          “We got all the heat shield data we needed and then some! ”

    Summary: almost, but not quite entirely successful.

    Launch successful. Booster separation and boost back burn looked good. Booster failed to relight some of its engines and hit the water hard. Successfully deployed the 20 starlink satellites. Successfully reignited an engine in flight to prove potential for de-orbit burn on future flight. Re-entry looked good and less spicy that some previous attempts (subjective). Such a soft landing that the ship flopped into the water without exploding and floated for a good long while (possibly still floating for all I know). Got some great drone footage flying over the heat-shield.

    So the ship itself is looking increasingly good (so far) but they still seem to be having some issues with the booster.

    • smallmancontrov 5 hours ago
      Speaking of which, are there any fan theories on why the boosters seem to have persistent issues? Or is the plumbing still churning fast enough that we keep seeing N=1 issues for successive designs?
      • ceejayoz 4 hours ago
        The 12th flight was the first to use the third generation Raptors, so this is only their second flight test.
      • jdminhbg 1 hour ago
        Until the past couple launches it was the ship that had the issues. Had to be blown up a couple times, failed to relight in vacuum, lost an engine and nearly failed to get to the suborbital trajectory last time. Meanwhile the booster had the most spectacular success in the catch, and has yet to result in a catastrophic failure.
      • laughing_man 4 hours ago
        The leading theory, from what I can tell, is slosh. The flip on separation is relatively violent, and while there's not much fuel left compared to the amount at launch, it's still heavy enough to do damage.
        • staplung 3 hours ago
          The cast I was watching said that during the flip and boost-back the booster is pulling 11 Gs. That's a pretty hard hitting water-hammer for sure.
          • smallmancontrov 3 hours ago
            Oof, yeah, one good slosh at 11G is probably all it takes. On the bright side, there is probably a trajectory that works and I wish them luck in finding it!

    It’s interesting the cognitive dissonance this brings out in me. As much as I think Musk carries a fairly reprehensible aura, I would still like to see SpaceX succeed. Space has a funny, transcendent way of inspiring us.

      • pstuart 4 hours ago
        Agreed. Separating those thoughts are valuable here and in life in general.

        But like a lot of tech, the cool shit can have serious negative effects as well and it's important to be able to, again, acknowledge both appropriately.

        The success of SpaceX has made him the richest man on the planet, and his money makes him dangerous.

      The tiny part of SpaceX that is actually about space, yes. Unfortunate that it has been bolted onto the hulk of Musk's AI fever dreams.

      You don't need to virtue signal your dislike of Musk-the-person to be allowed to show your admiration for the exploits of SpaceX. I don't care what you think about Musk and I'm pretty sure I'm far from the only one. Yes, SpaceX is doing great, hopefully other companies will follow their clear lead and make space access more reliable and 'affordable' so that those great wheels-in-the-sky may one day become reality.

        In "V2" page 179 Dornberger writes:

        "Do you know that your closest colleagues (including von Braun) have stated in company at Zinnowitz that it had never been their intention to make a weapon of war out of he rocket? That they had worked, under pressure from yourself (Dornberger) at the whole business of development and only in order to obtain money for their experiments and the confirmation of their theories? That their object all along has been space travel?"

        The men had been arrested by the Gestapo and were going to be executed. Dornberger was also threatened with arrest, but he managed to get von Braun and the other released.

        • WalterBright 2 hours ago
          Another interesting factoid about the V2 program is it accelerated the collapse of the Reich.

          How can that be, you might ask?

          The V2 program was an incredibly expensive program, and sucked up enormous resources. But the V2 proved to be an inconsequential weapon, and did very little damage, because its guidance system was primitive.

          The V1, ironically, was effective. Not because it wreaked critical damage on Britain, but because it was cheap to build and deploy, and the British spent a great deal of resources trying to stop it.

          It reminds me of the current drone warfare.

          Hitler also demanded that it be used to attack London, blowing up civilian homes, when it would have been much more effective attacking the staging areas for D-Day.

      > Musk carries a fairly reprehensible aura

      What's your favorite reprehensible thing about him?

      • atq2119 5 hours ago
        I don't think your comment adds value to the discussion. By now, you either know what's reprehensible about Musk or have decided to either ignore it or support it, and by extension be reprehensible yourself.

        But in case any bystanders genuinely wonder, my personal "favorite" is him doing what is clearly meant to be, or at least unambiguously invoke, a nazi salute not just once but twice, and standing by it (plus, of course, his political activities in that direction).

        • WalterBright 4 hours ago
          If he meant it to be a nazi salute, why did he do it in conjunction with saying "I give my heart to you"?

          Currently on TV is a WW2 documentary narrated by Tom Hanks. It's pretty good, with significant coverage of nazis. I recommend watching it. I'm a bit of a history wonk, and have read extensively about WW2. I'm afraid I don't see any parallels between the nazis and Musk.

            Go on - would you give the latter link's "my heart goes out to you" gesture publicly at, say, work, or outside a synagogue?

          • muwtyhg 4 hours ago
            And responding to the backlash by posting Nazi-related puns seems like a bad way of clearing your name or trying to distance yourself from the accusation.
          • smallmancontrov 4 hours ago
            He's done "I give my heart to you" on video, too, and it looks nothing like the nazi salute that he clearly did at the inauguration, twice, in celebration of the victory of far-right populist politics in the USA.

            The rhetorical parallels between Musk, his affiliates, and the nazis should be clear to anyone with remedial knowledge of history, let alone someone who calls themselves a wonk: scapegoating racial outgroups isn't a subtle strategy and Musk's pursuit of the strategy is not subtle.

            WW2 is the end of nazi politics, not the beginning. In the unlikely case that you missed the parallels in good faith, I recommend the Richard Evans books to learn about the beginning and middle of the nazi movement.

              "pedo boy" sounds like an insult, not a charge. Musk has said it was a common insult among schoolboys in S Africa. While I don't know if that is the case or not, I do know that different countries have different insults. And it does sound very much like a schoolboy insult. I'm sure all of us can remember schoolboy insults from our youth.

              This is evident from you changing his word from "pedo boy" to "pedophile".

              I remember once a book of Japanese insults that was passed around at work in the 1980s. We all thought it was very funny, and for the next month or two heaped such insults on each other.

              My dad was stationed in Britain during WW2. The GIs encountered a bit of culture clash. To an American "knocked up" meant getting pregnant. To the Brits, "knocked up" meant being tired. Imagine the ensuing hilarity...

                Musk hired a private investigator to confirm the pedophile allegations (which failed, of course).

                          'motherfucker' is a common phrase even outside of strictly english - speaking countries , and very few people go on to explain how the person had sex with a mother.

                          'pedo boy' is impossibly uncommon, regardless of what the singular defending belligerent claims, and furthermore he went on to publicly accuse the person of actual pedophilia.

                          yeah : i'm sure it didn't fail in court due to unlimited deep pockets and lawyers on retainer.

                          is there anything beyond willful ignorance ? You and I have had differences of opinion before, but yeesh -- talk about a hill to die on, defending elons' shite behavior during that phase.

                  Musk did hire the private investigator after the rescue worker sued him for $195 million. I agree Musk shouldn't have done that despite being angry about being sued.

                  Musk won the lawsuit.

                  Musk also publicly apologized.

      Not me! I'm rooting against SpaceX lol

      Starship is the SpaceX Cybertruck - lots of impressive engineering, but still doomed by terrible design choices from you-know-who. Stainless steel is just such a terrible choice for a rocket this large. Doomed the whole enterprise.

      I know launches are exciting. Landings, doubly so. But eight launches to get to the moon is not a good rocket. Sorry.

        >> Stainless steel is just such a terrible choice for a rocket this large.

        Honest question, but what do they usually use?

        • ggreer 4 hours ago
          Aluminum alloy and carbon fiber, because both have high strength to weight ratios. Steel is denser, so its specific strength isn't as high. But it retains strength at both lower & higher temperatures, and it's much cheaper. It's also cheaper/quicker to modify a steel design, as welding is easier than aluminum (at least for low carbon steels used in Starship). And if the same structure were made of carbon fiber, it would likely have to be fabricated from scratch.

          I think choosing steel has helped Starship, as it allowed the ship to survive reentry and land in the ocean despite heat shield failures. Had the ship been made of aluminum, I'm certain earlier missions would have broken up when the aluminum heated up and lost its strength.

      They juiced the engines up big time with the Raptor 3 upgrade. The rest of the stack is leaner and meaner too, but engines are the single biggest upgrade.

      It's why they have plans to elongate the stack further. If they have this much TWR to go around at liftoff, they can afford to cash in that extra thrust to pack more fuel.

      The more you accelerate early instead of later, the less fuel you have to subsequently carry to get to the same speed so it's more efficient.
  • georgeburdell 6 hours ago
    Seems like the booster landing burn did not light all the engines and so it crashed into the water.
    • ChuckMcM 6 hours ago
      Yup. Some of the Youtubers (like NASA Spaceflight) had video of it hitting the water pretty fast and hard. That said, this is the only test failure so far. I'm cautiously hopeful they get Ship to touch down. (it will explode after it does because of physics but stepping lightly onto the ocean will be a win)
      • ChuckMcM 5 hours ago
        And I sit corrected as it was able to lay down without rupturing the tanks and 'sploding. So that's another win.

        What I find really amazing and cool is that while its reentering the engineering team can drive it around and look at heating effects on tiles/spars/etc all while retrieving telemetry by Starlink. What many people don't realize is that early capsules were the shape they were because that was the limit of what they could simulate for re-entry forces. The ability to get real time confirmation of systems response in re-entry is a capability that we've never had. So there's that.

        So at this point it looks like they are down to un-reliabile raptor relights on the booster.

        Congrats to everyone who worked on this.

        • dylan604 4 hours ago
          The size of ship being big enough to create a hole in the ionization to continue to communicate with Starlink is something that I think gets underappreciated.

        I guess they also failed to explode it
        • pclmulqdq 5 hours ago
          I am pretty unconvinced that any of the past explosions of starship used that feature. It’s very convenient to have an “explode” button so you can say all of your rocket detonations were intentional, but they are often leaking fuel or dropping chunks before they explode.

          This was a great flight, though.

        • chasd00 4 hours ago
          from what i understand it kind of is a failure. It's suppose to tip over, explode, and sink. That way you don't have all this ITAR regulated tech floating around in international waters.
          • testing22321 1 hour ago
            They actually said they’ve been trying different techniques to not have it explode like rolling.

            This way they got way more heat shield data, which is, I think, their most critical item they need to learn from and iterate.

      • cucumber3732842 6 hours ago
        >it will explode after it does because of physics

        Is this just a fancy way of saying lightweight fragile aerospace tube with hot stuff all over the outside and flammable stuff on the inside will not respond well to falling on it's side or is there some other thing going on here I don't know about.

        • ChuckMcM 5 hours ago
          Sort of? Everything is weight. And since it isn't a design feature to lay down in water there isn't any weight budget for making that modality survivable? So typically when it falls (and this thing is really tall) the interior tanks detach from their mounts and hit the inside walls and rupture. The skin is still hot, oxygen and remaining fuel mix and it goes boom. This time we had fires but no boom. I look forward to hearing what was different.
          • m4rtink 5 hours ago
            Starship is quite a bit sturdier thanks to the stainless steel used & very efficient engines that make it possible to have the structure heavier.

            We had it demonstrated in the past with Starship surviving multiple burnthroughts and now in failing to explode. :-)

        • ACCount37 5 hours ago
          No, that's exactly what happens. Most of the time.

          There was a couple of times when SpaceX accidentally soft landed a Falcon 9 first stage into the ocean, and had it just float around. They're yet to do that trick with Starship though.

          EDIT: Of fucking course.

      • DetroitThrow 6 hours ago
        How many times have they managed to catch it in the last 8 or so missions? There have been a few misses like this already with the boosters

      It was going in the water anyway, but yeah, it touched visibly faster than it should have.
    • ButlerianJihad 6 hours ago
      The actual objective was to crash very slowly into the water, and to that end, I believe they planned for about 13 out of 33 to light for the "landing burn". But only about 5 lit up at that time, giving them a higher-speed crash-landing. However, the landing site was exactly where they needed to be, and done in complete safety, so that is good.

      They had been explaining the post-ignition abort from last week, and showed how 4 out of 33 engines had failed to light on the first stage. This was due to some kind of pump malfunctions. They said that if 1 or 2 fail, it's OK to launch, but more than 2 is an automatic abort. So they were able to replace the finicky motors and fully test them out.

      Who knows what caused the underthrust for the landing burn, but at least all 33 engines were operational at launch, and they got plenty of data from this test run, and all Starlink v3 satellites have been deployed successfully for their "suborbital speedrun", so this test flight is doing really awesome!

      • ls612 6 hours ago
        Damn so this probably means another identical suborbital flight in 6-8 weeks. It is looking less and less likely that we will see either prop transfer or a ship catch this year.
        • davmar 6 hours ago
          i don't think so - the ascent looked good. i don't think they need to put the ship on another suborbital trajectory because the booster landing burn failed. also, i don't think this impacts prop transfer or ship catch - both are separate problems.
          • ls612 6 hours ago
            I think this is technically true but that they want a seamless suborbital flight (like the last two for the Block 2) before they move forward on those other goals.
            • eightysixfour 5 hours ago
              Why wouldn’t they only care about seamless ship flights, to get some value out of the launches, while they’re still learning and figuring out how to light booster?
        • NetMageSCW 6 hours ago
          They don’t have to catch the booster to test any of that.
    • wat10000 6 hours ago
      The “chopstick” catcher arrangement seems awfully fragile. Would the ground equipment have survived this if it had been a real catch?
      • pixl97 6 hours ago
        Yes, because it would have landed a few hundred meters out from the chopsticks. It swings in towards the catcher as part of its slowdown. If it doesn't slow down, that doesn't happen.
      • tenuousemphasis 6 hours ago
        They generally initiate landing aiming just off shore and only adjust to the landing pad after everything is nominal. So yes.

  • adolph 6 hours ago
    Its amazing to see this beast and think that all the firey stuff isn't the primary energy source (although totally necessary to pushing the mass out the back fast enough).

      The reason it’s very small is that almost all of the energy in hydrogen and oxygen is not stored in the chemical binding energy of these things going together.
    
      The vast majority of it is stored in just the rest mass energy of the protons and the neutrons, which chemical burning doesn’t affect at all.
