#62Re: Starship's Tenth Flight Test
#63Some kind of failure in the lower engine area. Figure it's going to burn up on entry? EDIT: made it. I suppose it was meant to blow up on landing in the ocean? It would have been nice to examine the burned components — but perhaps they had not intended to retrieve it that far away anyway.
Maybe just some part of the construction (possibly even just the strinngers or simply some nook or cranny that is fully eclosed) got presurized or was pressurized for the whole time by just air that could not escape. That would be fine for the fligt so far - until it started to heat up from re-entry heating. The stainless steel would be still fine if heated to hundreads of degrees, but the expanding gass could maybe…

Not quite, but it's a major milestone. Still quite a bit of work to go on the rapid reusability part (burnt flaps, oxidized body, missing tiles, tile waterproofing). Starship might actually deliver payload to orbit on flight 11.

#65So the starlink simulators its deploying right now are empty platters that will burn up in the atmosphere from what I understand. Next missions they’ll be real statlink sats. Are these different than regular sats? It sounds like they’re able to handle more bandwidth but I don’t know.
The economics of Starlink basically require high cadence Starship launches with 50+ Starlink v3 satellites on each flight.

Yes, although one booster engine failed at the start. Not a big deal. :)
Re: Starship's Tenth Flight Test
#67Are the tiles on Starship going to need replacing after flight like the Shuttle? There isn’t a permanent material that can handle all the heat yet? Serious question, my space expertise is only from KSP.
The tiles themselves work fine, but how to best mount them? where do you need them? Can you make them thinner? do you need anything underneath? what kind of gap do you need between tiles? Those are the things they're hoping to understand in these tests.
The Shuttle tiles were technically reusable AFAIK. The issue was that they were very fragile and the Shuttle for the most part could not tolerate any heat getting through the tiles (being aluminum), so every flight needed to have a perfect heat shield. Starship is a bit better on that end, as stainless steel is a lot more capable of tolerating heat and I think the tiles are a bit less fragile. Still, would be ideal to figure out how to not drop any tiles.

They're currently experimenting with things such as actively cooled tiles (which I presume were installed on this ship, since they were on the last two).
I personally think the likely best case is that they'll have to go over the ship and replace some here and there before launching again.

But yes, “rapid reusability” is a ways off. I expect they’ll be spending weeks inspecting and repairing ship and booster before reflight for a few years, but they’ll drive it down over time.
TBD how “rapid” the reusability ends up being in the end.
