You missed the real important bit. " Most steel alloys get brittle at cryogenic temperatures. That’s not the case for stainless steel with high chrome-nickel content. It gets stronger in cold conditions, but it also maintains ductility. That means stainless steel has high fracture toughness, which could prevent small structural imperfections from developing into cracks." With the cryo fuel loaded, that thin sheet of steel is stronger than carbon fiber, on top of all the other stuff you mentioned.

I think if a normal, less ambitious person would leas spacex, they would accomplish much more, elon musk just wants to much, and often the things he want are just too early, science is not prepared yet.

My Soviet university "diploma work" back in 1987 was to test this type of cooling for rocket re-entry, porous pressed metal powder was used, however there were problems with incostintent gas flow in different parts of provided samples. Hopefully perforated solid metal will work better than baked together particles, I really hope such protection is possible (although not 100% sure), only tests will show.

@BRAVOZULU DWEST boathouse I don't think it's possible to calculate these things precisely because of nature of turbulence, it is not really predictable and may create very local effects when one part of rocket will be heated much more than other part. That's why tests are still necessary. That's why wind tunnels are still used. However, it's hard to replicate all conditions of re-entry in wind tunnel, SpaceX is right to build cheap test rocket.

I think the biggest challenge will be with the baffle diffuser 'heat shield' that the methane will flow through; there will be cryogenic methane on one side and high-pressure semi-ionized hypervelocity gas on the other. This will create a high thermal gradient across the baffle plates, and I am not sure if anything short of an actual flight test will prove/disprove this approach. If it fails, it could doom Starship and jeopardize SpaceX's investment funding. If it performs as designed, we enter a new era in spaceflight and human exploration.

Amazing content and good material knowledge! Another interesting consideration is application of torsional loads unto the material as Kepler's laws take over. This certainly makes isotropic materials like SS a preferred choice, at least until we can improve composite material science to respond equally well to compound forces. However, there will always be limitations associated with substrate selection for various coatings/shielding, especially as their CTEs vary and internal strain is created. Looking forward to other videos!

Mate what a fantastic video, really well explained and I love the isogrid idea.

There's a couple of errors or misconception in the video and one key part brushed over: 1. "Starhopper" is just the nickname of the test vehicle being built in Texas; it has this name because when SpaceX were testing the software and systems required to perform landings with the Falcon 9 they built a short version of a Falcon 9 (with just 1 Merlin engine) which was called Grasshopper. The actual rocket that's going to Mars is called "Starship" as a whole, with the upper stage bearing the same name and the booster (which is only necessary for getting Starship off of Earth's surface) being called Superheavy (as a spiritual step-up from Falcon Heavy). 2. The Starhopper vehicle being built in Texas is not the same height, weight, etc as Starship (just as Grasshopper didn't have the height, weight, etc of Falcon 9); rather it's just designed to test propulsion and the final stages of landing (being able to throttle the engine properly, have a reliable and rapid gimbal system, etc). They do have a very rough approximation of the final Starship's CG vs center of pressure with Starhopper, but it's only really rough data. There's also rumours that they might attempt a simulated mid-air engine-out, where the rocket would descend under 1 or 2 engines (instead of all 3 they're installing on Starhopper; Starship is currently planned to have 7 engines), likely at a tilted angle - engine-out redundancy is important for something that's envisioned to carry 100 people to Mars and (later) back. 3. They're also going to be building a full-scale prototype of Starship separately to Starhopper; this full scale prototype was meant to be under construction now at the Port of Los Angeles, but SpaceX didn't renew their lease and are moving construction to Texas, so there's likely not much in LA right now (that can't be moved by truck, rather than barge, to their new Texas facility). It's not clear whether this would be a vehicle that later turns into an operational vehicle, but that full scale prototype will actually test things like the aerodynamics of the rocket (including the special aerodynamic control surfaces, have the proper manufacturing techniques (such as those involved with the active cooling system), etc. Starhopper will get the control laws tuned into the ballpark, the Starship prototype will refine these to transport customer payloads and humans. 4. This is the key part you missed out - a lot of materials, such as carbon composites, aluminium and even many stainless steels, get weaker when they're subjected to the cryogenic temperatures experienced when being used to store -200C liquids. The specific stainless steel (a slight variant of 301 SS for the tanks, a slight variant of 310 SS for the heat shield outer wall) that SpaceX will be using however actually gets about 50% *stronger* when it experiences these temperatures. The combined cryo + hot strength advantages of steel has ended up resulting in the payload capacity of Starship rising compared to prior carbon composite-based plans.

They are generally easier to weld than aluminum alloys and not prone to the same fatigue life. In general Stainless steels have gotten significantly stronger (UTS) in the last 30 years and therefore can be considered an option that was not feasible in the 60's of 70's.

I love this channel, this was a bit of a bizarre video though. Mentioning the fact that the Starship has to reenter "not once, but twice" kind of down plays the significance of what Spacex is doing here. They're not just developing a rocket for the purpose of going to Mars and coming back, they're trying to design a rocket that can go to Mars, come back, and then leave again any number of times. The goal is a fully reusable rocket than can go to space and reenter tens, hundreds, or maybe even (a bit aspirational) thousands of times. And it's not just for Mars, it'll also do routine launches of satellites and cargo to places like the ISS, geostationary orbit, etc. It's intended to completely replace the Falcon 9 and Falcon Heavy, so it's going to be doing quite a bit more than going to Mars.

It might not be a far-off time where someone is on Mars or a Jovian moon trying to explain to their students or children (one and the same?) What the days of aluminum & carbon fiber rockets were like and why it took six decades to make reliable rockets out of steel. I should plan to see a Falcon Launch soon - there will be more while Starship is being tested.

Yes, the rocket could be reused BUT the initial challenge is to get it up to mars, bring it back and most importantly have it's crew not die. Then, when the rocket is safe home it will be possible to do repairs, change the outer most layer or shields or whatever. The rocket itself will be the same but it won't land and go back again instantly. The structural integrity of the steel won't be the same the first time it launches and when it comes back. What I'm trying to say is that the initial challenge is to: build rocket to get to mars and back, then the next challenge would be different, use old rocket to get people to orbit.

One important factor you didn't give enough attention to is the fact that with very large spacecraft, there is more room for carrying extra weight. For smaller spacecraft there is a very small margin and any extra mass means significantly higher launch costs per kg. However, for a large reusable spacecraft the equation changes dramatically. There is much more room for extra mass and reliability and reusability become far more important. The main reason why super large rockets have not been used till now is the lack of reusability meant the greater complexity of larger rockets was less economical than small ones. They would have had to launch large numbers of satellites on every launch to be economically viable.

They don't call it "waste" because they throw it away, they call it that because it is a waste of time, energy, and money. The more material to be removed, the more time it takes (man hours and machine time) to remove it. And it takes a lot more electrical energy to do this. And all this brings up the cost. They don't get much money back from their aluminum waste. Designing parts with less of this waste is super important in producing things economically.

Wondering if you would do an update video on Starship now that it has been 2 years its truly amazing how they developed both Starship + their new raptor engine. And if you notice in Starships current development they have reverted back to using ablative tiles which is interesting.

Please do one on the raptor engine as well!!

Use of propellant for cooling during reentry is not as unusual as you think as this is not the first time it was proposed on a space vehicle. It was featured on a lot of Phillip Bono's designs such as the SASSTO and ROMBUS.

The X-20 Dyna Soar's heat shielding also would've used liquid coolant during peak heating.

Who come here after the launch? Starship roll multiple times at highest speed and still intact before be self-destructed. Its shown that Stainless steel is ultimate choice for it and maybe later space rockets.
