FAQ

  1. When (first) orbital flight? First integrated flight test occurred April 20, 2023. “The vehicle cleared the pad and beach as Starship climbed to an apogee of ~39 km over the Gulf of Mexico – the highest of any Starship to-date. The vehicle experienced multiple engines out during the flight test, lost altitude, and began to tumble. The flight termination system was commanded on both the booster and ship.”
  2. Where can I find streams of the launch? SpaceX Full Livestream. NASASpaceFlight Channel. Lab Padre Channel. Everyday Astronaut Channel.
  3. What’s happening next? SpaceX has assessed damage to Stage 0 and is implementing fixes and changes including a water deluge/pad protection/“shower head” system. No major repairs to key structures appear to be necessary.
  4. When is the next flight test? Just after flight, Elon stated they “Learned a lot for next test launch in a few months.” On April 29, he reiterated this estimate in a Twitter Spaces Q&A (summarized here), saying “I’m glad to report that the pad damage is actually quite small,” should “be repaired quickly,” and “From a pad standpoint, we are probably ready to launch in 6 to 8 weeks.” Requalifying the flight termination system (FTS) and the FAA post-incident review will likely require the longest time to complete. Musk reiterated the timeline on May 26, stating “Major launchpad upgrades should be complete in about a month, then another month of rocket testing on pad, then flight 2 of Starship.”
  5. Why no flame diverter/flame trench below the OLM? Musk tweeted on April 21: “3 months ago, we started building a massive water-cooled, steel plate to go under the launch mount. Wasn’t ready in time & we wrongly thought, based on static fire data, that Fondag would make it through 1 launch.” Regarding a trench, note that the Starship on the OLM sits 2.5x higher off the ground than the Saturn V sat above the base of its flame trench, and the OLM has 6 exits vs. 2 on the Saturn V trench.

    There’s a new (lord I hate the new name) thread from The Ringwatchers @Ringwatchers about the Hot Stage Load Head et al. Someone did an unroll and it’s here. I haven’t time at the moment to go over it in detail. It looks like two ring sections will be above and below, and they will be reinforced because they are irrelevant to the hot stage sieve. The Hot Stage Load Head has been reinforced in several ways; there are pictures. The assembly will go into the can crusher.

    Have we seen any sign that B9 has been/is being modified with the additional hot-stage ring and the new FTS ? Right now, to me this seems to be the long pole, more than the OLM.

        Yeah, there is approval. But I’m more talking about the retrofitting, which doesn’t even seem to have started.

    New Booster Hot Staging section spotted earlier today. - 7/20/23 - https://starshipgazer.com

    Image 3

    SpaceX made a prototype like this, with lots of vertical slits, and then scrapped it. It was suggested at the time that it might have been for hot staging. Well, that’s looking more likely. The current article has the outlines of the vertical slits but they haven’t been snipped out.

      Potentially basic question: does anyone know if this section is structural and needs to hold all the weight (plus various forces during flight) of the second stage? As in, there’s no hidden scaffolding in the center of the engines?

    Static fire!

    Announcements on the webcast:

    • Test duration 2.74 seconds, with 4 engines shutting down prematurely.
    • Vehicle and pad look good. Preparing for propellant offload.

      Plate seems to have survived this very well. Didn’t see any bits flying up either, and white cloud seems good, so very positive overall.

      But 4 engines shut off and I think John mentioned they were aiming for 5 seconds, so I bet they’ll go for another run in the next few days.

      If I remember correctly, they can launch with up to three engines missing. I guess the early shutdown of the fourth engine after ~2.74s triggered an abort of the static fire, which was supposed to last for 5 seconds?

    Tweets from Elon Musk @elonmusk.

    7:51 PM - Jul 9, 2023: “3 more engines for the meaning of life.” Meaning 42 Raptor engines total for Super Heavy and Starship together. It’s with an upskirt photo of a Starship, though with 6 engines. I can’t quickly find an authoritative statement of the configuration, but since 2021, it seems that people have been stating 3 sea-level gimballing engines in the center, and 6 Rvacs (vacuum Raptors) inside the circumference (so one added between each existing pair of RVacs for a hex array). Everyday Astronaut tweeted a reply at 8:57 PM - Jul 9, 2023, “So 33 on booster, 9 on ship. Which will be the first 6 X Vac ship?”, so he seems to be thinking 6 RVacs.

    The Ringwatchers @Ringwatchers have a 10-tweet thread (via threadreaderapp) analyzing it. They see a Hydraulic Power Unit: they say that, since S26 on and B9 on have the electric Thrust Vector Control system, this has to be a picture of S25. The engine shielding has been removed – for inspections? for redesign? The COPVs have been removed too. There are other details, like the interior camera, the static firing stiffeners on the RVac (vacuum Raptor) engine bells to prevent damage from sea-level flow separation, et cetera.

    Two Elon tweets in sequence:

    • 12:35 AM - Jul 10, 2023 “Looks like we can increase Raptor thrust by ~20% to reach 9000 tons (20 million lbs) of force at sea level”
    • 12:43 AM - Jul 10, 2023 “And deliver over 200 tons of payload to a useful orbit with full & rapid reusability. 50 rockets flying every 3 days on average enables over a megaton of payload to orbit per year – enough to build a self-sustaining city on Mars.”

    Edit for the record: Zack Golden @CSI_Starbase tweet on Jul 9 this picture. It showed Starship’s config as mentioned above. But the 3 center gimballing sea-level engines are lined up with 3 of the 6 RVacs on the rim, which I think would slightly reduce their range of motion.

    Musk replied 10:29 PM - Jul 9, 2023

    Inner engine gimbal angle is limited in some directions, due to impacting outer engine nozzle, but probably ok

      Huh, the tweet seems to be visible even without a login? If not, the underlying image is https://pbs.twimg.com/media/F0zTpR6XwAAnVvl?format=jpg&name=4096x4096

      The tweet says

      Chris Bergin - NSF @NASASpaceflight 9:09 PM - Jul 11, 2023

      Say hello to S24.2 at Starbase. You’re interesting!

      Photo by Jack Beyer (@thejackbeyer) for NSF.

      I think the naming convention of Snumber.number or Bnumber.number is for a test tank or other test subassembly.

      One suggestion is that it’s a test of the lunar Human Landing System. S normally means it’s on Starship, and maybe the reinforced holes at the top of the tank are the landing thrusters, or the openings for the thrusters.

      There’s also the suggestion that it’s a hot staging ring, but it was objected elsewhere that that would be on top of a booster, not in a Starship.

      Another suggestion is that it’s a “Frankenbarrel”, combining two tests.

    WOW! OLM Water Deluge System conducts its first full test! That was super impressive. No more rock tornados, I’d say!

    http://nsf.live/starbase

    I wonder whether the MP4 will attach here? … edit: Nope, it seems not. See https://imgur.com/a/CQwvvl0 . Audio, but don’t turn it up.

    Edit 2: https://www.youtube.com/watch?v=QgTqqGaU-Bg is a closer view from Starship Gazer @StarshipGazer, but with some unrelated chopstick stuff at the end apparently.

    Edit 3: DRAT! I hang out in this thread, not the main group, and didn’t see that @llamacoffee had posted “[Chris Bergin - NSF] WOW! OLM Water Deluge System conducts its first full test! That was super impressive. No more rock tornados, I’d say!” here.

      Zack Golden @CSI_Starbase added on 2:09 PM - Jul 17, 2023:

      Interesting things to note about this test:

      1. In the near future this will have an even higher volume of water
      1. The system appears to be in the process of being expanded and might eventually have double the amount of high pressure gas tanks feeding it.

      On point 1, someone asserted (based on “Individuals on various discord servers”) that it was only the center manifold.

      Zack had a later tweet, 3:37 PM - Jul 17, 2023:

      The purpose of the water system is purely to keep the steel plates from melting.

      Without the water, the plates would be disintegrated, but the actual foundation would still survive as long as the booster cleared the pad fast enough.

      The upgraded foundation is the key to success here. Had the original foundation been constructed the way it is now, the pad would not have failed during the first launch attempt while using Fondag on the blast surface

      IMHO it’s impossible for that type of failure to occur again.

      He clarified in a later reply, “As I said, the water is not preventing mechanical forces from being transmitted through the plates and into the foundation. That’s not it’s job. It’s purely for thermal protection.”

      I think this test was done without the plates that close the top of the connection to the center section. If I’m correct the next test will look quite different.

    New comment from /u/santacfan on Reddit:

    Starbase live-

    12:57am- Short piece of pipe lifted into the pit

    7:27am- Rebar lifted over by the deluge area. No idea where this is going. Maybe just staging it for the OLM pit?

    5:45pm- Crane on the left side lifts deluge feed pipe and repositions it

    6:20- Lift goes up at S25

    6:29pm- Deluge pipe lifted out and sat by side of pit. Workers gather around the end

    6:36pm- Lift at S25 goes down

    6:37pm- Lift goes up to Chopsticks, near pivot point by the tower

    6:43pm- Deluge pipe lifted back into the pit

    6:49pm- Forklift drives under OLM

    7:06pm- Appears to have another one of the plate extensions. Goes between cryo pipe leg and new stairs leg

    7:39pm- Disconnected from the forklift

    8:45pm- Scaffolding and tarps being set up under the OLM. The great weldathon continues.

    9:15pm- Grover moves back closer to the deluge tank farm and starts lifting counterweights back on

    10:02pm- Grover finishes stacking counterweights and turns towards the water deluge tank farm

    (This gets synced)

    Bigger deluge test. WARNING: LOUD!

    NASASpaceflight: SpaceX Starship Full-Pressure Deluge Test (YouTube). That has &t=2425s in there to start just before the test. That’s video timestamp 40:25, wall clock at upper left 1:09:50. (Tweet)

    RGV Aerial Photography (but at ground level) (YouTube). I like this because it’s 3 different views, some zoomed in, some distant. (Tweet)

    Andrew C - Rocket Future @TheRocketFuture tweet. A lot like the first. I tried to attach the video but Lemmy wouldn’t take it.

    SpaceX tweeted a couple of things. Picture from ground level and close: Full-pressure test of Starship flame deflector (Twitter). Video, up a bit, just outside the legs, slow motion (Twitter). You can see right down the bidet’s butthole. This is the clearest shot showing that the intent is not to spray cold water on hot metal, but that it all looks angled to the sides.

    (((Geoff))) @DeffGeff (Twitter) sped up the video to normal speed.

    Video posted by He Who Musk Not Be Named, up and further away.

    Marcus House @MarcusHouse 7:02 PM - Jul 28, 2023 (tweet) noted about the SpaceX image, “If you look closely, you can see that much of the water is shooting out in the exact pattern needed for the 33 engines. It is a real thing of beauty.”

    Oh, and Zack Golden @CSI_Starbase tweeted 1:26 PM CDT - Jul 28, 2023,

    Wow! This full pressure test of the flame diverter system was pretty incredible! Crazy there is still an additional water tank missing from this.

    I can’t wait to see this during the first Static Fire test. Would not be surprised to see that as early as next week!
