[@UncleEarl97]

Given that we saw some flames coming out above the nozzle of one of the Raptors during SN9's flight, I wonder if that wasn't a somewhat different problem from the second engine failing to ignite properly as SN8 came in for its landing? SN8 seemed to be a fuel mixture problem. I would expect them to do more than just one Static Fire test for SN10. What do you folks think?

[@David-yo5ws]

@@UncleEarl97 Well we know they can do 3 static fires in one session! I think the fire did cause a problem with 1 engine or the 1 engine had a poor fitting that caused the fire AND failure. I still have a gut feeling the problem is the sensor feedback to the Engine Control System receiving 'false' data caused by the free-fall in some way and this causes the wrong start-up cycle, leading to engine failure. However, they should see that in Telemetry Data AND I would have expected McGregor, Test Control Centre to have test results of Horizontal tests too.

Remember the idea of a carbon composite SS/SH? No rapid iteration, insane cost. In hindsight, this is a masterpiece process of engineering and breakneck development.

[@MartinRunesson]

Yes, but it´s a part of the evolution and not wasted time. When starship matures, I bet we will see some parts replaced by composites to reduce the weight.

[@albertvanderheiden7419]

The cost of the pure material from cabon are higher indeed. The labor cost mmm? i dont now. The carbon fiber mold i remember was just a enormus drum who spin and wrap the carbon around it. Saves you a lot of welding for sure.

[@tirthachakrabarti5912]

Carbon fibre or other composite materials themselves are light but with supporting stuffs and extra heat shield (that steel doesn't require) make them heavier than steel effectively. Also, final starship will be mass produced rapidly (like ~1000 ships with 1 or even 2 ships per week) so I don't think even the final version will have much of composit material.

[@jakob4321]

@@albertvanderheiden7419 The main difference is that with carbon composites each layer would have to be cured before another could go on top of it. And no doubt there would have been a decent number of layers. And there would have been zero room for error with the curing process. One air bubble in one layer of the composite and it could be catastrophic for the entire rocket. Carbon composites would have been ridiculously complex to pull off. It would've been cool to see, but I'm glad they chose this route. It will be much, much faster to develop and test.

[@rolandkinzer3211]

i think we can expect parts of super heavy and starship to have carbon composite components later on when the iteration is done. it also depends a bit on the overall weight distribution and so on. but i believe there could be some significant weight savings. for example the cargo area or crew area could be made lighter with carbon vs. steel

I will speculate that that 'rebar cage' that was lowered into the ground at the Orbital Launch site, may be the start for the lifting and support tower for the Super Heavy. Also, that control valve being delivered to the 'concrete block house', makes it feasible that that structure is the control valve center for the orbital base. For Fuel, oxidizer and cooling water.

The size of SN10 makes the engines look too small to do the job. I can't wait to see the vacuum raptors being installed.

That 'ground equipment' is built for serious pressure. I've worked with Table D flanges which are good for 150 psi (10+bar) but these flanges on the manifolds are way bigger. Motorised (the orange box on top) ball valves - two the same size and one smaller. Interesting. Might be for salt water being made from stainless or re-compress methane?

80 percent cried seeing SN9 like that

[@BakuganBrawler211]

At least the engines from SN9 are mostly intact besides some flattening hopefully that means they’ll be able to figure out what caused the engine failure. Hopefully this triple light will fix the problems while Raptor reliability is improved 🚀 still believe it’ll go in 2024 if not a prototype by next year, why not 😂

[@adwood201]

The plumbing around that engine seems to be much more complex than earlier iterations...

[@SPLYKEABLE]

As constructive feedback: would it be possible to show the explaining banners for a longer time? I absolutely adore your work, but often only have the time to skip through your videos. As a consequence, I often miss the descriptions

[@donrubottom8723]

How do you drill a hole deep enough for that rebar column that close to the beach?

[@paulfrederiksen5639]

Having drilled many a well in heaving sands, I can tell you that it is possible but there is as much magic as science to it. You have to have a very light touch on the handles.

[@ahahn928]

What is the ground service equipment?

[@magicalmusicalstreetr3057]

The question is why are the Raptors self destructing on the landing? Debris at lift off? shockwaves from takeoff? They need sensor's around the raptors....As Elon stated they need to light all three use two of the good engines keep one as a backup if one fails..

[@pdtech4524]

The local scrap man is rubbing his hands together!! SN11 being readied behind the scenes? 😯

[@kataseiko]

Look, the raptors have the serial number on the side.. Why is there no number on the Starships?

[@patcht2523]

Has anyone mention in blogger world or twitter how much these test rockets cost? I guessing over 6 mill???

[@cosak23]

looks like re-inforced pump house

We're watching being built one of the most revolutionary transportation system ever . It's good to remember.

[@topsecret1837]

Could the Starship, if it had to abort, land in water by slowing itself down before doing a second belly flop so more of its surface takes the brunt of the impact for passengers? If it could be made buoyant, that would make it incredibly safe, especially considering stainless steel tends to corrode more slowly than other metals, possibly even making it recoverable.

[@Cediii4ris]

Yeah sure because let’s just hit water with literally the entire surface what could go wrong

[@Usstampcollectersatkiwistamps]

Looked like the impact was slow, but it actually hit at 120 mph. Deceiving because of its size

[@topsecret1837]

@@Cediii4ris Id still like to remind you the entire structure is built to survive 5-7 bars of pressure. If it can withstand that much force, it should be fine hitting the water at 30-60mph, which was what I was getting at.

[@Cediii4ris]

@@topsecret1837 but it’s stupid to do on the belly. 90* and it’s safe, falcon 9 also did a hard water landing at ~90° and was unharmed.

[@Dalidoso]

Salt water (chlorine) is very bad for stainless steel.

[@stevearnold100]

Please tell me they've done additional QC's on the Raptors!

[@ecohen2010]

I believe the real QC checks come mainly during static fires and test launches. They can learn a little on the test stand but only way to really test all three raptors working together, at altitude, is on a starship in flight. I'm sure by Raptor SN 100 or so they will have many of the issues worked out.

[@davidnoble868]

"Rebar cage" That answers how they are able to create a stable foundation that can hand hundreds of tons on what is essentially a flood plain. It's hard to judge scale, but it looks like they're drilling pilings 50(?) feet deep.

[@eurekakennel]

Wonder if that is a support tower base for the orbital pad?

[@theallknowingorbitalteapot1010]

Just wondering if anyone knows why they still work on Starhopper? I thought it was there for show after it's hop

[@eurekakennel]

Communications and camera platform now.

[@Chuckiele]

Hopper has a lot of uses. Most stuff you see attached to it has been installed after the hop.

[@Brabant076]

The raptor engine looks so tiny. :D

[@bnuttsgee]

Its the thrust that maters.

[@alexnest9038]

@@964cuplove actually size matters especially for the rockets

[@ianskinner1619]

anyone who works construction will understand that footing means that something very big is going in there. be it heavy or more likely tall.

[@giovannifoulmouth7205]

How much would you pay for one of those destroyed Raptors?

[@bill_ruppert]

Those are the secret sauce. Russia or China would pay a lot.

[@dirktween244]

Before or after the materials have been recycled ? ?? Raptor SCf6, 3kg of aluminum carbonite; being used to create foil fin of SN12 ?
