    There is a lot riding on V3. SpaceX cannot afford to take too many launches to get V3 solid. If 2026 is another 2025 (3 V2 failures in a row followed by 2 V3 successes), then they can forget about landing on the moon before 2030.

    My hope is that Flight 12 goes nearly flawlessly (at least gets to soft splashdown) and they can start testing in-space refueling in July/August.

    If they can demonstrate in-space refueling by the end of 2026, then they have a shot at a lunar-landing demo in 2027 and a crewed-landing in 2028. But a lot has to go right for that to happen. Here's hoping it does.

      question: what will happen if orbit refuelling goes wrong? Won't it destroy everything in orbit?

        No. What is the mechanism through which you suspected this could happen?

          Kessler syndrome presumably?

        Liquid handling in microgravity has always been weird. Big gas bubbles in the fluid, surface tension effects causing liquid to float in balls in the ullage, stuff like that. Turbopumps break if they ingest a larger bubble.

        There could be some odd failure modes I would think. Failure to pump the liquid, broken pumps, who really knows? My guess would be that a failure mode would be a big spill, a failure to pump, only partially refilling, or broken turbopumps before an explosion.

      My theory for why they have been failing so much recently..

      2018.. Young brilliant engineer starts working for spaceX, absolutely the most exciting space company, on an awesome new rocket that will finally be a better launch vehicle than Saturn 5 and be able to enable all sorts of cool space stuff. Just a naive young nerd, dont really know anything about Elon, not into social media.

      2024.. The Elon stuff in the media is unavoidable and obvious, they guy is a freaking nazi, suporting trump, supporting right wing parties in EU.. The talented engineer either leaves or stops giving a shit and quiet quits.

      This process times several 100, in an experimental rocket design project, where any tiny flaw can make the whole thing fail.

        Have you met hardware guys? This is not how they operate, in my experience.
        • everyone 5 minutes ago
          I mean I might be a hardware guy myself depending on your definition. I've never dealt with rocket engineers.. Are they "hardware guys" according to you? If so it seems you are using that term incredibly broadly.

        “They [sic] guy is a freaking nazi”

        Presumably you’re at least fairly intelligent, nonetheless propaganda has done its job. Fascinating…

        Just FYI, engineers are one of the groups most likely to lean right.

        I’m hopeful tomorrow’s launch goes flawlessly!

        That's makes a lot of sense becuase the Nazi's were notorius for not having good rocket engineers

        Aren't theories supposed to include some conjecture? This here is pure deduction.

    This is the first flight of the new engines. They look so much sleeker and simpler than the previous two generations:

    * And supposedly with a 20% power increase to boot!

    • MattDamonSpace 48 minutes ago
      Oh wow that photo is from years ago but you’re correct, this is the first flight of that design
    • chasd00 50 minutes ago
      The stats are pretty out there. Iirc just the fuel pump, which you can probably pick up and put on your desk, generates 100k HP.
      • jvanderbot 42 minutes ago
        Well, it's powered by bleeding exhaust from a very big rocket.
        • TomatoCo 26 minutes ago
          One of my favorite clips to give a sense of scale for rockets is this one. https://www.youtube.com/watch?v=70u748VALt4

          I show someone and then I tell them, that's not the rocket exhaust. That's the exhaust for the engine that runs the fuel pump for the rocket.

        • jasonwatkinspdx 20 minutes ago
          Nope, Raptor is full flow staged combustion, so both the fuel and oxidizer have dedicated preburners and turbopumps each.

    > The two modified satellites will test hardware planned for Starlink V3 and will attempt to scan Starship’s heat shield and transmit imagery down to operators to test methods of analyzing Starship’s heat shield readiness for return to launch site on future missions

    Hope we get to see those images. Would be awesome to see a 3rd person view of starship in space.

  • cooper_ganglia 1 hour ago
    These are always exciting, even if it's more of the same. I love that we live in a time where we can regularly watch huge rockets launch into space with intentional issues just to see what might go wrong and how best to monitor/solve them.

    Congratulations, everyone, at being alive at the best point in human history so far!

      With super high res onboard camera footage too.

    Dang, they aren't catching the booster this time, but I guess V3 is practically a new vehicle and validating the next Starship launch is probably too critical to risk damage to the launch site for now.
    • amarant 1 hour ago
      Oh hey, you're right! Somehow I read "water landing" and interpreted it as landing on one of the barges (ocisly or jrti) any clue why that isn't the case? Is super heavy just too big for the barges maybe?
      • ggreer 37 minutes ago
        They won't use barges because the booster has no landing legs (to save weight), and because the booster is massive compared to Falcon 9. Also Starship is meant for rapid reusability, and it can take days to return a barge to port and unload the booster. Getting barge landings to work would be a distraction from the goal of Starship, and SpaceX already has Falcon 9 for current payloads.

        And they won't attempt a catch with the first V3 booster because it's not worth the risk. They can build a new booster every couple of months. It takes much longer to build the launch/catch tower, and they don't have any spare towers yet. A catastrophe during a booster/ship catch would set them back a year, so they'll only attempt a catch if they're confident it will succeed.

      • pixl97 1 hour ago
        Superheavy is 10x larger than the Falcon. Its thrust would sink the barge.
        • robocat 53 minutes ago
          Yeah. Rocket first stage Approx. unfueled mass:

          Super Heavy: 200000 to 280000 kg

          Falcon 9 first stage (without Falcon Heavy side boosters): 25600 kg

          • jjk166 19 minutes ago
            So 200-280 tons. A standard barge can support 1500-3000 tons of cargo. Even with the added weight of a catch tower and a healthy factor of safety thrust isn't gonna sink the barge. Far more likely the major hurdle would be stability issues with how tall it is.
      • wmf 1 hour ago
        It doesn't have landing legs so it has to be caught by chopsticks. They're skipping the barges; either it lands back at the pad or it doesn't land.

    Everyday Astronaut has posted a video on this launch https://x.com/Erdayastronaut/status/2057163096817332576?s=20
  • pixl97 1 hour ago
    There is a 70% chance for storms in the area tomorrow so it's very likely going to be a scrub tomorrow.

    They have really invested in content lately - like, actually having someone spend some time creating the text on this page. And a number of long form videos. IPO time, I guess.
  • chasd00 53 minutes ago
    Really looking forward to seeing raptor 3 fly. Those engines are insane.
  • purpleidea 35 minutes ago
    I don't know why they aren't doing more booster catches. Kind of a bit disappointed they keep skipping. Either they can land them or they can't. If it's not consistent then they're avoiding the possible failure so their stock price (launching soon) stays up, otherwise just prove it's solid and actually works.
    • ggreer 23 minutes ago
      They can build new boosters pretty quickly. New launch/catch towers take a lot longer, and they don't have any redundancy yet. Also they weren't going to reuse their V2 boosters once V3 was ready, so they could learn more by testing things like intentionally disabling an engine during the landing burn or flying at a higher angle of attack.
    • GMoromisato 28 minutes ago
      V3 booster has a lot of changes, including a brand new downcomer, an integrated hot-staging ring, and 3 instead of 4 grid fins. Chances of a RUD are not 0.

      If Flight 12 blows up in space, they've already got Flight 13 almost assembled. It might delay them a month, maybe. But if a returning booster destroys the launch pad, it would delay them much longer--maybe a year.

      With those stakes, it makes sense to not try a booster catch until they're sure it's going to work.

    I am watching Elon give a long speech about the launch, scarily delivered at high speed, without pause. Including a Bitcoin marathon promotional informercial complete with an on-screen scan code. "That QR code is your boarding pass." He just repeated several paragraphs verbatim from a few minutes ago.

    He occasionally mentions the aspirational 100x reduction in launch costs.

    AI slop. Yuck, Youtube. Surely Google could have AI moderators catching this crap.

    • sfjailbird 48 minutes ago
      That's a fake youtube channel that is somehow allowed to squat the SpaceX channel name. It's been going on for years, including the crypto scam. Baffling. Maybe a big middle finger from Google to Elon.
    • jiggawatts 44 minutes ago
      It probably is AI generated.

      My very first exposure to "AI spam" was trying to watch one of the Starship test launches, the second one if I remember correctly.

      That was around the time that Elon bought Twitter, so he removed all publicity video streams from third-party platforms like YouTube and moved them to Twitter's streaming service.

      I wanted to watch this on my big TV, so I was hunting through YouTube for the stream. I found the most likely looking one and watched as Elon got up on a stage, started waffling on about how this is the "future of humanity" and then with 40 seconds to go before the launch the (entirely realistic) AI voice was dubbed over and started offering "double your Bitcoin if you transfer to this account", with the obligatory QR code in the corner.

      I was actually impressed by the audacity!

      The really frustrating thing was that YouTube then promptly blocked all content even vaguely related to the launch! It was impossible to keyword search for anything that said "starship", "spacex", etc.

      It was a scary preview of instant corporate censorship.

      I'm sure the person (or bot!) at YouTube "meant well", but sheesh... they just erased the online presence of dozens of legitimate space-fan channels like NASA Space Flight. And NASA. And SpaceX's official channel too!

      Ironically this meant that the only remaining matches were 100% scams.

        > Ironically this meant that the only remaining matches were 100% scams.

        I am wondering if some of this is unmarked paid advertising. I can't imagine any other incentive for Youtube to effectively align its brand with Ick.

        Ads, as one of the prophets said, are the Devil.
