PNSF - NASASpaceflight.com@NASASpaceflightFuture vehicles and their upcoming assembly hall, called the Gigabay, are in focus ahead of Flight 11, all aimed at the next phase of the Starship program.
Elisar Priel@ENNEPS·Join us 🔴LIVE🔴 Today, October 2nd, from 2:00 p.m. CDT / 19:00 UTC on @NASASpaceflight Starbase Live stream for another Raptorside Chat.We’ll discuss all the latest developments at Starbase, and beyond, and try to answer any questions you may have!

Or else maybe a different, more heat resistant grade of stainless steel.Possibly I'm hallucinating, but I seem to recall other bicurved domes and nosecone sections being shiny. As to a different alloy, stainless is already heat resistant, but certain other steel like HSS does have a somewhat higher melting point. I think to go higher than that, you need a refractory coating, which is why I asked. I'm still not sure it's really all that much less shiny, which is why I asked. Catdlr's pictures seem to show it as less shiny, but maybe I'm just seeing what I think has to be there.dull v. shiney has been going on since the beginning - it's the mfg process that makes them dull or shiny.Bocachicagal pic attached

This process essentially stretches the outer surface of the metal, so it starts shiny and flat, but one stretched into shape, the surface finish will lose its shine.

In fact it's even 5s longer than (planned) on Flight 9The minimum time spent trans-sonic is interesting. Have they changed the definition? Or are they decelerating 240% faster? It doesn't seem like it will be in thicker air (lower altitude) to achieve this, unless terminal velocity is significantly lower.There was comment about the Flight 10 splashdown and whether it was sufficiently controlled - it seems that's not the way forward.
Here is the corrected updated online press kit with the launch time in UTC (the SpaceX website shows GMT).
Meanwhile, at the village....Two Teslas, a Starlink on the roof, and a Superheavy in the backyard. Suburbia in the 20s.https://twitter.com/StarbaseTX/status/1976013752530268644
MattZ@wvmattz·Booster 15-2 arrived at the launch site this morning after the trek down Highway-4 in Starbase! @NASASpaceflight covered it all live.
MattZ@wvmattzAfter arriving at Pad 1 a few hours earlier, Booster 15-2 was lifted onto the OLM. Mark one more item off the pre-launch checklist. Flight 11 is coming up soon!
SpaceX@SpaceXFlight-proven Super Heavy booster moved to the pad at Starbase ahead of launch
Hard to tell from the photo, but this doesn’t look like new construction (at least to my eyes). Is this one of the buy-out houses that had solar shingles put on them? Might need to have Mary or Nomadd chime in for this answer.
