马斯克 2022 解读 Starship 与 Starbase 最新进展

0:00Hi, it's me, Tim Dodd, the Everyday Astronaut. Welcome to Starbase, Texas. Today, we're going inside Starbase with the Ultimate Tour Guide, Elon Musk. He's going to take us through the high bay to see where Starships are assembled. We'll also see the new Mega Bay under construction

0:14and talk about SpaceX's plans to get this rocket flying. Now, I must warn you, some of the things we talk about are pretty technical, but I've got a handful of videos to help you understand what we're talking about. There's links in the description to those videos. And stick around, because in the next videos we're going to go up the launch tower, then we'll see the new Raptor 2's up close and personal,

0:32and talk about the Falcon 9's Merlin engine in great detail. And if you happen to find this video valuable, consider dropping a super thanks as a tip, or become a channel member, or a Patreon supporter, for early access and to help show your support. Alright, let's get started. So we're making good progress with the Mega Bay over there.

1:02So that should be done in a month or so. That's tricky the scale from perspective wise right here it almost looks the same you know just from our perspective but it's about 30, 40 feet taller. Okay. So it's more about just this case. So Girth is more important than Langley. because we just need, we need to be able to construct more ships and boosters.

1:37And you can see like the high bay there is, it's okay if you've got like maybe two or three works in progress, but like you like maybe have two or three workstations in this, in the high bay. In the mega bay we can have like really almost a dozen, maybe at least ten workstations.

2:00So that's why the sort of with the length are more important there. Especially as we try to really get the production line going, we need more workstations. The high bay here is okay for making for a low production rate, but as you go to a higher production rate, you just need more workstations.

2:21Yeah. And so that's booster, right? Yeah. Or half a booster, half a ship it looks like. Yeah, exactly. It looks like you do have those, your vents there, the cold gas or the, the foliage gas vents? Yeah. Well, we're using the allage gas for attitude control. So instead of having separate attitude control thrusters, we're using the allage gas itself

2:57for attitude or reaction control. So basically for attitude control in, once you're in orbit, or basically when you're in a vacuum, you don't meet, the impulse needed is very low. So, in earlier design iterations, we had a separate cold gas attitude control system with nitrogen bottles, but that actually doesn't make a lot of sense since we've got a bunch of olives that we're gonna vent anyway.

3:26So might as well use the alleged gas for basically attitude control and small delta V changes on OVID. Yeah. Okay, I had to admit, I'm you taught us to question your constraints. So that makes sense to me for the booster, because the booster doesn't need to do, basically the second you turn the engines off, it's gonna need to want to vent a lot of its stuff anyway.

3:54And that's also corresponds with its first flip. But for a starship, like with docking maneuvers and stuff, how is, to me, in my head, the Venn diagram of needing to depress a tank and the Venn diagram needed to do a orbital maneuver don't always have a huge amount of overlap. So is, or is it not a concern?

4:14Is it always going to be on tap? When the ship gets to orbit, you're going to have still pretty high pressure in the oxen fuel tanks, which are autogenously pressurized. So you've got a hot gas disoxction and hot methane. And you have a lot more all this pressure. You actually don't need any more all this pressure.

4:45So you've got more pressure than you need. OK. and the deal a bit and the landing burns are done with the header tanks. So you actually wanna vent the main tanks down to just above atmospheric pressure. Well, really, you wanna have enough pressure in the main tanks for structural stability.

5:10So it's pressure stabilized, but not any more pressure than is needed for pressure stabilization for atmospheric entry. Right. And it's going to, but when it gets to orbit, it's going to have really a lot more pressure than is needed for atmospheric entry. So we would, in any case, end up venting the main tanks

5:34down to the pressure needed for reentry. And so we'd retossing that gas away. OK. So if it's free, you might as well use it. Yeah, we're going to dump the gas anyway. So then why have separate tanks and everything? You might as well use that gas for attitude control and small maneuvers.

5:57And then even then, we'll still end up dumping the remaining gas that's not needed for entry. OK. So because of that last statement, you'll be dumping it anyway. Definitely kind of. Yeah, actually, when you look at the old design, It's just like obviously it was pretty dumb to have a separate called gas reaction control

6:24system because we have excess, allaged gas. And if we simply have a main tank vents that vent in the direction that you'd want, then and there's no need to have separate other structures. You can literally just use the vent. So at some point, those will probably have almost an Apollo style four-way set of nozzles

6:57or something, right? Or because right now they're just facing pro-grade, basically. Yeah. So that would be for settling thrusters, basically, those ones up there. and there's this side thrusters that you don't see on right now that will be added. So side vents. And yeah. So it just still surprises me that they're not doing, you know, like capturing and doing

7:28some kind of high pressure or higher pressure, you know, hot gas thruster anymore when you have. No. The hot gas thruster was definitely over-engineered and unnecessary. So, just using all his guests for, for basically for for small thrust is the obvious move in this case. So, in retrospect, the obvious move.

7:53It's much more efficient than having separate cold gas thrusters. Well, guess not, not think about it. There's probably hasn't, there's never really been a rocket where the upper stage or the actual spacecraft is 99% of giant empty tank or a drained tank. Every other vehicle, space shuttle, very small amounts of just the ohms pods, basically, that stuff.

8:14But there's never really been a vehicle that's on orbit where it just went through a four or five minute burn. And now it needs to, yeah, that actually is really, really interesting. That's so crazy. So it's a significant optimization, mass and cost savings to use the ELLage Gas for attitude and reaction control that have separate cold gas

8:39trusters. I love it. I'd say that's like one of the biggest improvements that we've made. I got to admit that was one of you. We're talking about the last time. And I kept thinking about it. Actually, it was literally a curt to me in real time. It occurred to me while I was explaining it to you.

8:55I was like, wait, what are we doing? It was one of those things that kept just being like, that can't be right. But yeah, I mean, it is, it seems to be. Yeah. We kind of went through this exercise for the ship and then it was like, wait a second, we should do that for the booster as well.

9:16And that just occurred to me literally while I was doing the interview with you. Like, okay. Do you mind saying a few things or, or do I? What do you think we should discuss? I don't know. Yeah, I wanna see Elon's interviewing skills. Well, I mean, so this is Joe Petrolaco. He's head of a booster engineering.

9:42And I don't know if anything you want to say. Like, good point of things and describe. What's new on like seven and stuff? What are some of the new things you guys are working on? On booster seven, which is down at the pad right now, it's been quite an improvement over the first boosters So we built four and five.

10:01We simplified a lot of things. Like there was a lot of, you just learn when you put things together the first time we were able to get rid of a lot of it and combine a lot of it. It's got some new arrow features. So it's got upgraded grid fins and it has chines or strakes on the side of it.

10:14And those are gonna make the reentry performance much better. So we'll be able to actually come in at a lower velocity and get a higher precision when we're coming in to the tower catch. So we're really excited to try that out. Okay. Then I got one for both of you guys. Why are the strakes or whatever?

10:29What are the chimes? Chimes? Why aren't they 180? It sounds like wind chimes. It's just the chimes. It's just the chimes. It's just the chimes. Why aren't they 180 degrees to each other? It looks like they're about 140 or something offset. Yeah, they're about 120, actually. What they do, it's not about just increasing the wingspan, if you will.

10:50It's about getting the area of the cylinder of the rocket to pressurize. So those features help the rest of the rocket pressurized. So it's more than just the area of those chimes. You actually get more net drag on that section of the vehicle. At an angle, right? Not. Yeah. OK. So you're basically using that to increase the overall surface area when it's coming at some kind of angle of attack.

11:12So the booster is very, it's very bottom heavy with all of the engines down there. And so you're trying to actually add drag area down there as well. And when you do that, that can let the booster pitch up higher. Otherwise, if you don't have the chance, it wants to just come in first.

11:28So we're going to come in pretty button first. It's going to come in slightly less. Well, you can pitch it up 120 degrees. Yeah. You can get much more control authority. And further, and it's a little bit more than just increasing the cross-section of the vehicle. Because you're not coming in.

11:45The integrated pressure profile on the base. So you've got the sort of the experienced wind of is hitting the cylinder of the vehicle and then it's rolling around the cylinder and it's kind of like losing pressure as it rolls around. By having the chines be not 180 degrees but a little lower down, we're catching more of that air that's escaping.

12:15And so technically you actually have slightly less cross-sectional area, but you have more integrative pressure at the base. Gotcha. Let's keep moving quick while this machinery's firing up. But these are very primitive chines. Yeah. We've got first attempt and not expect to change them a lot over time.

12:33Well, one of the things that I love about it is that you're covering up the COPVs. So it's both a COPV arrow cover. Double use out of it. Double use out of it, which I love. I do fear that it makes us less rigorous about getting rid of COPVs. But more complacent that they're have a home.

12:50It's as many as we wanted under them. So they were still a person. Okay, good. But like if you say like what's, what are optimized chines, you'd actually want them to get bigger as you get. Wider at the bottom. Yeah, wider at the bottom. It begins to start looking like chip flaps.

13:05Yeah. Yeah. You can put the simulation right away. Especially as you're coming in, like you said with such a big amount of mass and basically a dry can above it, you'd really want the center of pressure to be as low as possible. Right. So that brings me to another question then.

13:20I'm curious why you guys are still sticking with grid fins instead of more traditional stabilator or some kind of conard or something. Well, this is a frequent topic of an conversation. Exactly. We discussed this a lot. I mean, essentially, our optimization right now is getting to a little bit.

13:41So there's a, yeah, so we know how to use grid fins from Falcon 9. Grid fins are much more consistent than flaps as you go from hypersonic to super sonic to trans sonic to subsonic. So you're going through these different markers regimes and grid fins are much more consistent than a wing or a wingy thing.

14:08Yeah. So, especially as you go subsonic, the center of pressure on any kind of flat surface shifts significantly when you go from supersonic to subsonic. So, but I, you know, could you be lighter than a Gritfen? I think there's a good chance you could be. There's also another factor which is the actuator power needed to turn a grid fin is much less

14:40than is needed for to turn a wing, a sort of a wing like thing. Similar. Yeah. Especially as that center of pressure changes. It increases the torque on the motor, right? You're necessarily going to be ordered so short that even if the center of pressure changes, it's not far from the rotation point.

14:59And so the total pork required does not change dramatically throughout your mock-breaking transitions. Yeah, yeah. We are constantly talking about can we have the right number of grid- Like for- They designed correctly. Yes, so like we're not saying we're right to be clear. Like we're definitely not optimal, but we, it'll work.

15:19Yeah. Like it's probably, we're working as good and it's one less problem to solve. It's also like we obviously don't need four. I think we could probably get away with two. Definitely not more than three. Well, you're old 2016 original OG ITS had three, and I remember that being a pretty unique design consideration.

15:49There's a number of iterations that this vehicle has gone through is insane. Before it even hit the pavement, it already iterated like... So many times. Well, I started questioning, you know, why, for me, I always thought the grid fin was a lot of it was being able to retract him on a cent, you know, get him out of the wind stream, but now that you're not retracting him, I was like, well, that and then also, you know, the actual mass savings, you know, 50% of your, the mass of a grid fin is perpendicular to your control

16:16motion, you know, your control authority. So I always wondered if like they, how that would, the trade would be on just, yeah, compared like normal wingy thing. If you know your position well and you know your wind's well, you can in theory have a ballistic arc when you do your boost back burn that is very accurate with nothing.

16:41Except, and we tried this in the early days of Falcon 9, but the problem is like Like any small asymmetries on the vehicle will cause it to go crazy, basically. It'll spin up and start flapping around and it'll just start oscillating and rotating. And. And. And. Yeah. Exactly. So technically you don't actually need massive surfaces.

17:14You just need to be able to take out the asymmetries of the, of perturbances on the vehicle, and any error that you have with respect to position or your boost back impulse. Yeah. And even wind conditions and things like that after a micro. Yeah. So you really don't, the control surfaces you need are actually not very big.

17:39And we've shrunk the grid fins significantly from where we started out. So they're much lighter. Yeah, but even with grid fins, we really should be moving to aspirationally two grid fins, but certainly not more than three. And the third one can be small. A little vestigial guy, and I like just imagining a tiny little guy.

18:06And I'm one sector. So, I think we have actually this is liquid oxygen tank section for booster 8. It's coming along very quickly right behind booster 7 and then the ship 24 nose comes. So this is the ship that we hope to bear with booster 7 for our first orbital launch. It's looking so much more refined already than even S20.

18:41Oh, can we see the door? On the back side of it? Corner. I mean, it's like a blow your mind. You'd be surprised, man. The internet sure loves that door. Yeah, you got to see the door anyway, so I guess why not. But because you're at this point planning to launch 24 with Starlink version 2 already, right?

19:12Yeah. Well, we'll see. But, I mean, it's just, like I said, it's not gonna blow your mind here, yeah. It's basically, it's like we call it the PES dispenser. Yeah. And it's kind of like that. It's the stalling satellites are, you know, in this rack, which looks like a friggin' PES thing.

19:43Cause they're like, you know, kind of like rectangular, just like a PES. and they're stacked inside the nose cone, inside the bearing. And since they're low profile, we only need really a small door. With a small door, we can use pressure stabilization. Like, we're going to retain pressure in the bearing.

20:05So we can, at least partially, pressure stabilize the nose cone. Oh, fairing. And then we don't have a humongous hinged door. But might later on, which larger pieces of cargo and things like that. Yeah, we can make a giant door in the future. But this, a small door always, a lot less than a giant door.

20:29Yeah, yeah. I would say, for a sense, that we could come up like third. Yeah, I feel like it just begs the camera. It's going wrong, we clear. Yeah, if the mechanisms inside jam up, that'll be pretty embarrassing. Right, right. But it looks like it's just begging to have like two big googly eyes with a funny looking grin there, you know, or something.

20:50So we are incurring some complexity for the sort of the racking system inside, because you've got to have a racking system. So it's more complicated than a pessus pesser. But it's the general principle, is it like spring loaded then or hydraulic loaded or something? It's a bunch of electric, it's electric.

21:15And with a bunch of mechanisms. And they just like roll themselves out and just zip out the door and... Sorry. It's inspired by pallet stacking technology. Yes, like I watch YouTube videos of a pallet stacker. Exactly, exactly. And industrial pallet stackers is the same basic principle.

21:37They don't look super simple, but they do work. And so it's the same basic mechanism. I mean, there's some risk of, you're loading it in at one G and then you're unloading it at zero G. So you could have some situation where you're unloading a mechanism and because you unload the mechanism, it now binds.

22:05So that's the risk that we best hard to test for. Yes. Yeah. Yeah. What? So you're planning to actually do your first set of Starlink version 2s on this vehicle? Or wait, is this 25 or 24? Is this 24? Which is currently scheduled-ish to be the first orbital attempt, right? So you are.

22:29So has the plan changed to go from kind of a suborbital to an orbital launch if you're going to be trying to pop out a couple star links. No, we're always going to go here. Our next launch is always going to be orbital. Full orbital, not? Yes. OK. So that would? Well, yes. I mean, yes.

22:47Well, cool. OK. Because for a little while, there's talk about B4 and stuff, and that's pointing back in the day doing like a just shy of orbit on the re-entered by Hawaii and stuff like that, never quite reaching. It's basically orbit. OK, yeah. There's no real difference. Mouse fart between them.

23:01Yeah, I mean, you could just, it's the difference between, I mean, you're going like three quarters the way around the earth. Yeah, I mean, you could. Was literally like 30 meters per second difference. So it's a layer is as small. Yeah, it's essentially over the last C. So there's just no point in doing, like why not, why do an extra loop around the earth, and have another, the overgrown.

23:27So. But really, I wouldn't say that there's like, high confidence that the first flight will work. I think there's a good chance that it does not reach orbits, that there's an issue with the booster or stage separation or what the ship doesn't start or, and then even if it does get to orbits, there's probably that the ship makes it down in tact is also not super high.

23:53This is why it's entering over the Pacific an unpopulated area. So if there is an issue, it's not a danger to people. Yeah. So one of the things that a lot of people were asking about after, once we started seeing the heat shield tiles, is why they aren't scaled like a dragon or like a rough shingle where they're

24:14slightly overlapping and tapering and thickness. You know, why are they just have the gaps and everything. I mean, you know, there's multiple ways to approach this. So it's not that like a single approach, it couldn't work. You could have a single approach. The thing that will happen or should in theory happen here is that when the tiles get hot, they will expand and

24:46tighten the gap. So the gaps that you see here should be smaller when the tiles heat up. And you know, you're really not gonna see a lot of heat going down through those gaps is our expectation.

25:07So, shingling does not seem to be important. You could be wrong about that. So, it's kind of a ramen vehicle. Yeah. It's close to trying to burn. Right, right. Yeah, the flow is not coming straight in at those gaps. It's like... It's, yeah, I mean we'll be coming in at an angle similar to the shuttle, like, I don't know, 67 degrees.

25:30So sort of like, if the ground is the surface of the earth, we're sort of coming in like that. Yeah. And it's a balance between generating lift. Like, for a reusable heat shield, we want to minimize the peak heat load. So the peak heat load is going to determine if we melt the tiles or not.

25:50And if you melt the tiles, they're not very good for reuse. So we're kind of balancing between generating lift. And yeah, so there's atmospheric density, velocity, and you don't wanna have like, be going fast in high density air. That's gonna be. You wanna kind of stay up in the upper atmosphere for a little bit longer than you would.

26:20You wanna slow down as much as possible in the thin upper atmosphere. So you minimize peak heating. That's the best goal. Minimize peak heating. Which is pretty much what designed the whole shuttle's airframe almost was that peak heating and controlling that peak, that peak queue.

26:39Yes, so we're gonna learn a lot from this first entry. I like said, if there's any issues, the ship will not, you know, if there's unexpected heating in some places, then the ship will fail on entry and it'll be that. Yeah. Is there any talks, speaking of failing and re-entry and all those things?

27:08And we guys, there were rumblings for a little bit, you guys, someone was talking about flying ship 20 still, or S20. Just on a sub-orbital. Yeah, we've moved on. ,

27:34We think we've learned, you know, what we need to learn really with the cybervital flights. And there wasn't really much to learn, so best of folks aren't getting too old. Okay. I mean, yay, but also, I don't know. I'm quite excited about that. Yes, true. Yeah, those 33 rappers I think will put on a pretty, that'll make up for the slow,

27:54slow gentle climb will be 33 shaking everything. I think what it will seem pretty pretty odd or like strange is that the Starship orbital stack is going to come off the pad very fast. Yeah. So yeah, it's got a high thrust weight. What's its best approximate thrust weight? I mean it should be like 1.4, maybe 1.5.

28:16Yeah. That's like already on five speeds because SRB's, once that, those lights, that thing just shot off, shoots off the pad, you know? Yeah. be like that. I mean it's yeah. I'm being disoriented to see something that big just accelerating that quickly you know it'll. For a reusable vehicle you actually want to have a higher thrust to

28:39weight than an expendable vehicle because thrust weight below one is not doing anything. So your propellant is not being useful below thrust weight of one so you actually want to have a higher thrust to weight for a reusable vehicle than for an expendable. For an expendable vehicle, the cost overwhelmingly is in the vehicle itself that you are losing.

29:04But for a reusable vehicle, if it's rapidly reusable and completely reusable, the cost of propellant is the single biggest cost of the flight. And so you want to have a high thrust to wait so that more of the thrust is useful. Yeah. So high thrust to wait, Rachel, literally is financially beneficial purely on the,

29:28you need less fuel to do the same kind of work. Like this may sound sort of mercantile, but it's actually the thing to optimize for is cost per ton to orbit. Like you can't cheat if you get cost per ton to orbit. It's not about what the mass ratio is or the ISP or anything. So although we're aiming to have a great match ratio, a great ISP, everything, but it's really what is your fully considered cost per ton to orbit.

30:01At the end of the day, yes, the fully considered cost per ton to orbit is the optimization. And any given technology is only relevant to the degree that it produces cost per ton to orbit. So thrust-to-weight ratio might matter more than ISP as long as it makes for a lower cost per ton to orbit.

30:19Yes. So the trade offs always end up with, does it decrease the cost per ton to orbit? And that's what matters more than it. That's racially, we don't always get right, but the thing that really matters is minimize cost per ton to orbit. And then for Mars or the moon, minimize cost per ton to the surface of the moon or to the

30:40surface of Mars. And just to give you a sense of just how much we need to improve it, it's really insane. Like right now the cost per useful landed ton to serve some Mars is inaccessible a billion dollars. So you can't count the heat shield or the parachute or the useful stuff. So the landing system's mass does not count.

31:07Only the, like in the case of the rovers, it's really just the rover that is the useful thing. So if the rover weighs a ton, then it costs a billion dollars to get there. It's a billion dollars per ton to Mars. And that's roughly what it currently costs. Now in order to make life multi-planetary and have a self-sustaining city on Mars, that

31:44number will have to improve to I think probably under $100,000 a ton. That would be a 10,000 times better than the current state of the art. To put this into perspective, how much of an improvement is needed? About 10,000 percent, 10,000 fold. That's what Starship is intended to do.

32:11Be 10,000 times better than the current state of the art. So, orders and orders and orders of magnitude. A lot of orders of magnitude. But it is, we're not breaking any laws of physics. It is possible to do that. Can we see up at the top or is there anything to see up there right now?

32:32now. Not really anything to see. I mean, I think we probably shouldn't take pictures of the inside. Not that it's super interesting, but I think we're going to be cautious about like pictures of the inside of so. Where's the lifting points on this one now? You can see the lugs up there.

33:14I mean, we need to move those lifting points. Those are out in a good position. So you don't want to have lifting points where the heat shield tiles are. We need to move the lift points to where the heat shield tiles are not. Are you still hoping to catch the ship too with the arms or what's the...

33:35I mean you are right? Yeah. How are you going to catch it I guess? Are you going to do the same thing with the tiny little lumps? Like the booster? Yeah, I mean it'll be very similar to the booster with In the case of the ship because we need to have huge hill tiles that go more than 180 degrees a little more than 180 degrees

33:58We'll have to have the Catch points kind of flip out But it'll otherwise be in the in the lead way the win Like you'd have to I mean this you'd have to have a part with he chills house pop out or or have something that's in the leeward side that swings out. One of the two. And you can't just have the, you can't catch them by the nose fins.

34:24You will sort of could, well, like what you're seeing there that doesn't have heat shield tiles will need to have heat shield tiles. Yeah, yeah. So everything's gonna have heat shield tiles. Just, you see a steel part at the base of the, but that'll have to have tiles on it. If it's attached, if the mounting point would be attached to somewhere on the leeward side of the flap,

34:50and the flap could rotate more than 180 degrees, it could get in line with this. It could be the same mechanism that does the quickie thing, could be just the flap itself. I'm not sure I understand what you're saying, but... If the catch ball thing is on the leeward side of the flap,

35:10and the flap can go beyond 180 degrees... Oh, that's... man. There's not the problem you want us to try solve. The huge challenge we have is the hot gas seal. Oh, right. You'd move that in the morning. Over center of that. Yes. Like frankly, the thing we need to do, I think, is move the Ford flaps more towards the leeward side.

35:33This is a major internal debate. But there's a massive amount of optimization possible with the Ford flaps. They're in the wrong position. The wrong size, wrong position, wrong location. But they will work. Yeah, they're a start. Yeah, they'll work but they're far from optimal. What are the, under those one heap shields, you see the little, those like yellow puck things.

36:04What are those in, are those special or something? Just temperature sensors. Oh, I think so. either temperature or radio. I'm not sure. Okay. So, here are the antennas or temperature sensors? Well, what else is new since last time we were out here? Well, we're pulling the mega bay.

37:19What got you? Here's turning now. No, just this, I mean, there's a lot of improvements to make with the ship and booster design. But anyway, right now the important thing is just to get to orbit with, you know, some reasonable payload and then we have a whole series of improvements that we plan to

37:41improve the performance of the payload to orbit. But I really am not a fan of our forward claps. Like every time I look at them drives me crazy because they're so sub-optable. Well, your rate of innovation and your rate of iteration, those will be different sooner than later, I'm sure.

38:08Yeah, I mean, there's a potential scenario where we can delete the four claps entirely. And the shuttle doesn't have four claps. Right. that's because you're using dihedral control to control mostly pitch and you can still do a little bit of yawn roll with just a pair. So, huh. Because it's mostly about your center

38:39pressure, right? So, center of mass and center of pressure. It's a CISO. So you can just think of these things like the you've got a seesaw and your center of pressure like

38:58the wind the air is hitting the vehicle and you have a center of pressure it's like where's the where's that air gonna push the vehicle like If you add up all the wind pressure, where if you're pushing it with your finger, where would you, what's the center of that force gonna be?

39:26And then you've got your center of mass, which is a similar thing, but for mass. So you've got these sort of two C-saw things, center pressure, center of mass. If you have big forward flaps and big rear flaps, you can have a much more variation in where your center of fast is gonna be.

39:46And also what your angle of attack can be and how well you control the vehicle and different macho regimes and in the face of like a lot of wind shear, wind buffet. So. Because there is that, again, Soviet, like I don't remember what it's called, the mole or something that just had a dihedral wing on the back, it's supposed to be like a mini shuttle for them, like a two passenger Charon.

40:14What was that? The baron. No, not baron. No. It had like it's had foldable wings. And they basically the only thing is over those are fixed. They weren't dynamic. You know, so it's not like they controlled its pitch, but it basically had a really was supposed to have a really high angle of attack during initial ascent.

40:30And then the the back flaps just folded down. And but that was to extend basically have actual lift and do a horizontal landing. It wasn't necessarily like a dynamic link. But the idea was that you could control your overall, you know, pitch almost like, you know, virgin galactic spaceship two that folds in half, you know, how it can change its

40:49its whole center pressure and everything just, you know, in a single thing. But it's not again, that's not dynamic. It goes from one mode to mode one to mode two, you know, and same with that that Soviet one. But yeah, there's, you know, that probably becomes a lot trickier when you are trying to be dynamic and we are trying to actually

41:05pinpoint control your landing. I'm sure that it was just having a The thing that's like really counter-tutive about the Starship is that it's not an aircraft, it's falling. So we're just constantly trying to break as opposed to an aircraft that is, aircraft is trying to generate lift and fly horizontally.

41:26We are trying to generate drag and be as draggy as possible when we fall. So it's a very different optimization than an aircraft. So, yeah. It's about four times the usable area of the high bay. So it's only a little bit taller, but it's a lot wider and deeper. And so we have a lot more positions for, you may factoring the booster or the chip.

42:03So if you have a production line, you need a lot of stations, essentially, for a high production. So this is intended to have a lot of stations. Is some of this getting replaced by another building that's over top of some stuff, or is it? We are building a permanent battery building and replacing the tents.

42:27With the high bays and a one-way building. We're not building a building to encompass the high bay. That would be insane. But we're all going to be building a permanent factory building and replacing the tents. And we'll start the factory building from that side and kind of both and gradually replace the tents with a large permanent building.

42:48That's actually currently in the works, I guess. So you're still, you know, there's a lot of speculation, obviously with how quickly Florida's ramping up that this might be slowing down, but that doesn't seem to be slowing down too much if you're building a building out here. Yeah.

43:03Yeah. Hey, my, I'm Tim. Hi, Andy Krebs. Awesome. Yeah, sorry, what was your name? Andy Krebs. OK, cool. I was engineering for the non-quite hardware, so I do the high bays and factory up the spot for those who also launch the Google stage zero. A lot of the stage zero stuff. Yeah.

43:21The ground systems are, ground systems, especially inclusive of the tower, are at least as complicated as the stage one or stage two. Yeah. So should we go check out stage zero? Sure. Ha ha. Thank you, Elon, for all your generous time and thank you, Ryan Schlinski, for helping shoot and capture this incredible conversation.
