For the first time we saw the fully assembled Starship/SuperHeavy stack assembled on the pad. This is all designed to put Starship, the largest spacecraft ever built, into orbit, but we also got a really good look at a near complete thermal protection system, and that's critical to bringing the Starship back from orbit safely.

As an ex welder, two things-- first, stainless does take much higher temperatures to melt, but aluminum conducts heat hugely better, so you end up needing more amps to weld it. Not sure how that will affect things, I'm sure they thought of it. Second (and what I'm looking forward to see) is that stainless gets hot and starts making really cool colored oxides, way before it melts. It's not as colorful as titanium, but it can make beautiful blues and gold under the right conditions. So there's a chance if the heat and available oxygen are just right that it could turn partly blue or gold just past the tiles, which would be super awesome.

Regarding heat conduction: This does not apply here as the heat is applied more or less uniformly to a huge and thin surface - the heat simply does not have anywhere conduct to - maybe except for a bit at the sides. Maximum temperature before losing strength is really the metric they want to maximize, hence the very specific alloy of stainless steel that they are using

@jgottula 3 жыл бұрын

@@TheSe7enman I think it’s potentially relevant when thinking about how well (or not-well) Starship could handle the loss of a tile from its belly side: how efficiently can that exposed stainless steel area spread the extra heat around to neighboring areas and keep things okay; versus does it just heat up, become a hot spot, and melt through. Something like that…

The cubesat was a great idea. The original arm was to do that on all the shuttle flights before re entry, but never happened. Why not use a $1k cube sat for exterior inspection on each ship? Makes sense to me. Would just need to back haul the camera and data to the starship, should be easy.

@arik_dev 3 жыл бұрын

If you watch the 2nd part of Everyday Astronauts video though, Elon mentioned they're not going to install payload doors for the first 10 or so vehicles. He said this was because they would be improving the vehicles so quickly, that they wouldn't want to keep the tooling around for maintaining older models, as this is what happened with Falcon 9. And there was no point in putting doors on vehicles that would never fly real cargo. Now a cubesat is really small, so maybe they could deploy it in some other clever way. Maybe it could be stored at the top of the booster and pop out during separation?

the fact that the Raptor 2 is gonna have more streamlined and simplified plumbing makes absolute sense considering not only how many engines each launch will need, but Elon's ultimate goal of having Starship launches be as regular as jumbo jet flights. Less chance of damage, simpler to just change out as needed, probably easier maintenance....right now they're still in prototype data gathering stage, and as seen by the way serial numbers have jumped, they're already way ahead of where they thought they would be.

1:48 - If you ever do a "rostrum shot" (i.e., a zoom / pan across a high-resolution still), remember to add a small amount of gaussian blur (typically 0.3 to 0.5 pixel radius), or you get shimmery pixels on high-contrast edges. In theory this wouldn't be necessary if the software used proper area averaging, but most "consumer" software just uses pyramidal or box filtering (i.e., it only looks at 5 or 9 pixels), which isn't great and really messes up edges whenever the source image has more than 3x the output resolution (sometimes even less, depending on the exact algorithm).

Actually manufacturing the parts to spec, validating the parts, and making sure everything works nicely with eachother is where it can get incredibly difficult.

Scott, I don't know if you'll see this but I'll try. I sent this to Elon & Tim Dodds as he's pretty tight with the Rocketman. Starship has been experiencing minor tile loss during initial testing & I'm assuming that there's zero tolerance. I've worked for a major aerospace contractor eons ago but there are some low tech solutions that still apply today using the KISS principle. Why not apply a thin conformal coating of RTV like elastic substance over the entire area of protection? The elastic material could help retain the tiles through MaxQ & on to LEO. Heat on liftoff through to LEO would be sufferable depending on the material chosen by SpaceX. It could then burn away upon reentry leaving air pressure to hold them in place. Then a scrub down or solvent wash before reapplication of a new rubber, so to speak. Being elastic would help by spreading the vibration over a wider area, similar to ballistic armor principles. I realized that Elon would not be keen on anything that slows down his turnaround time but the application/reapplication process could be improved on rather than lots of engineering hours suffering through what the shuttle program dealt with. Cheers mate from a kiwi transplanted to the space coast. PS: I'm surprised that the other commentor could not determine your nationality from your name? Probably a pommie with a handle like spitfire, LOL

@solexxx8588 3 жыл бұрын

The tiles also have a fixed gap for thermal expansion. Boil-off of methane and LOX will also cool the tank walls if they are venting while at peak heating. Musk himself said that getting off the pad and away from Starbase for the first launch will be a victory because rebuilding the infrastructure would be expensive and take time.

Musk argues that using lots of engines makes sense, as it means redundancy, lose a couple of engines and Starship still reaches orbit. I’m not a rocket engineer, and I suspect neither are you. I can’t say what Musk’s thinking was. He may well have decided that having the same engines in the booster and Starship would significantly reduce development costs. But you can bet his decision was based on input from a group of highly experienced rocket engineers. My guess is that if they could solve the fuel feed for 9 engines, they can solve it for 27 or more. Just my uneducated guess. Best ask Musk.

Exactly, and I've been saying that for a while. People often forget that despite ending in a fireball, SN8 massively exceeded expectations - as the first serious test of the ascent and of the skydive, it wasn't expected to make it that far through testing, yet they were able to make a landing attempt on the first try. There's a reason SN12-14 were scrapped or never built, and why they didn't bother to fly anything after SN15 nailed the landing - they were far ahead of where they expected to be at the time. But my point is that just because that phase of testing went unexpectedly well, it shouldn't set expectations for the next phase. SpaceX allowed for no less than 7 attempts (SN8-14) to make the skydive work, 5 for the landing (SN15-19) and I doubt they're doing any differently for orbital flights.
