Everyday Astronaut explaining how flaps control flight (twitter video)
Elon: That’s correct. Essentially controlled falling, like a skydiver.Viv: ... but what's used to actuate the fins? Some kind of small motor?
Elon: Many powerful electric motors & batteries. Force required is enormous, as entire fin moves. More about this on the 28th.Elon: It does actually generate lift in hypersonic regime, which is important to limit peak heating
EA: Pop back out of the dense atmosphere to radiate heat away and then drop back in 🤔 awesome! ...
Elon: Better just to ride your max temp all the way down & let T^4 be your friend. Lower atmosphere cools you down real fast, so not crazy hot after landing.Oran Maliphant : Is “sweating” methane still an option?
Elon: Could do it, but we developed low cost reusable tiles that are much lighter than transpiration cooling & quite robust
\ok, I was steadfast that Elon's statements said nothing about future use of transpirational cooling, I will concede that this is not a defensible position anymore, ha ha])Scott Manley: And just like that I need to rebuild some of my descent models. So the AoA won't be 90 degrees, it'll provide lift to keep vehicle out of denser atmosphere until it loses enough speed.
Elon: Exactly. For reusable heatshield, minimize peak heating. For ablative/expendable, minimize total heat. Therefore reusable like Starship wants lift during high Mach reentry for lower peak, but higher total heat.ShadowZone: So this increases the probability of Starship having to do multiple aerobrake passes when going to Mars or returning, correct?
Elon: For sure more than one pass coming back to Earth. To Mars could maybe work single pass, but two passes probably wise.[Or discuss on r/SpaceXLounge post or Starship thread]

Here’s how #starship controls pitch, roll and yaw (in that order in this clip) using just 4 total flaps. This is a unique form of control. I don’t know of any vehicle that does this with its control surfaces perpendicular to the airstream. Cool stuff @elonmusk.…

Why does Starship only have 2 rear fins?!
We’re less than a week away from this year’s Starship update from Elon Musk. And before the party gets started, we’re already catching some major changes happening before our eyes.
The most obvious change is the fact that Starship only has two finny / flappy…

We’ve been focusing on production (now on SN12). Only need 250 bar or even a bit less for Starship/Super Heavy. Anything above 250 is nice to have & we’ll get around to it, but not needed for flight.
