  1. 0:00Hi, it's me, Tim Dodd, the Everyday Astronaut. Welcome to Starbase, Texas.
  2. 0:04Today, I'm gonna be taking you up SpaceX's launch tower,
  3. 0:06otherwise known as stage zero, with Elon Musk.
  4. 0:09We'll get the ultimate view of Starbase and learn more about just how exactly
  5. 0:13SpaceX plans to catch the world's largest flying object with giant
  6. 0:18robotic chopsticks.
  7. 0:20This is part two of our spring 2022 Starbase Tour with Elon.
  8. 0:24In the first part,
  9. 0:25we got up close and personal with the high bay and Starship prototypes.
  10. 0:29And in the next part,
  11. 0:30we'll get really in depth with Raptor 2 and Merlin rocket engines.
  12. 0:34So stay tuned. And if you happen to find this video valuable,
  13. 0:38consider dropping a "Super Thanks" as a tip below here on YouTube,
  14. 0:41or become a channel member or Patreon supporter for early access and to show
  15. 0:46your support. That being said, let's get up in there.
  16. 1:03I feel like you always talk about, you know,
  17. 1:04how you just wanna build an exciting future,
  18. 1:07a world where people get excited about stuff, wake up and wanna do cool things.
  19. 1:10And I gotta tell you standing right here, man. That's, that's
  20. 1:17pretty hard to not get excited about this.
  21. 1:21Yeah. I mean, this is pretty crazy. I mean,
  22. 1:24there's a custom built tower with arms that' are designed to catch the
  23. 1:30largest and heaviest flying object ever made and pluck it outta the
  24. 1:35air. <laugh> I mean, that's the theory anyway, so.
  25. 1:43Yeah,
  26. 1:43I think it's funny people actually forget now that they're actually built to
  27. 1:46lift and stack the rocket, that cranes have such bad wind capability,
  28. 1:49but one time the booster legs were gonna weigh a lot, Elon just said, you know,
  29. 1:53delete the legs, delete. We're like, well, what is he? Like? You just,
  30. 1:56just use the arms and then say it again, and we were like, "Oh wow,
  31. 1:59he's serious?" Okay. We better get on this. And now it seems normal.
  32. 2:03Or we think at least seems plausible. Yeah.
  33. 2:08I mean, it's still super crazy <laugh> but the more you talk about it...
  34. 2:14At SpaceX we specialize in converting things from
  35. 2:18impossible too late.
  36. 2:21<Laugh>.
  37. 2:24So, But it's pretty nutty because you're gonna have this gigantic,
  38. 2:30you know, booster coming back.
  39. 2:36I mean that's nine meters in diameter, not counting the chines,
  40. 2:39or roughly 30 feet in diameter. It'll
  41. 2:45weigh about
  42. 2:48250 tons just a bit on the heavy side we'll make that lighter over time.
  43. 2:54Weighs about 250 now, is that what you said?
  44. 2:56<Laugh> This is way heavier than... I think we can get the...
  45. 3:01Well there's there's the weight at different points.
  46. 3:04So it's like say like weight when the landing tanks are full
  47. 3:09versus weight when the landing tanks are empty is also
  48. 3:14what, how much ullage mass do you have..
  49. 3:17Dry, weight's kind of floating, you know, there's dry weight is yes.
  50. 3:20Kind of irrelative when it's actually in the air.
  51. 3:22Yeah. I mean there's several tons of air mass in the vehicle.
  52. 3:25If you just say like what's the mass of one atmosphere in
  53. 3:30that volume. It's several tons. Anyway,
  54. 3:37but
  55. 3:40I think we'll be able to get the mass well under 200 tons over time,
  56. 3:44but still pretty heavy. So you gotta like, you know,
  57. 3:47call it a couple hundred tons
  58. 3:50plummeting at you know,
  59. 3:56Let's see... well, I think our... the velocity at which we,
  60. 4:01we start up the engines is more than half the speed of sound.
  61. 4:04So this thing is still coming in really fast.
  62. 4:09Pretty much down in a downward direction. So then we light, the engines like
  63. 4:15I said, I think around Mach 0.5, give or take
  64. 4:20but it's only, you know, several hundred meters in the air,
  65. 4:24so it's gonna slow itself down very fast then,
  66. 4:28and correct any error. So like wherever the,
  67. 4:32whatever the X,Y error is when the engine's land it's gotta,
  68. 4:36take out the X,Y error and
  69. 4:40drop the last three of basically zero come in between the arms.
  70. 4:46The arms will be wide and as it's coming in, the arms will,
  71. 4:49will close go flush against the side of the vehicle and the vehicle will be
  72. 4:53descending through the arms. Those tiny little,
  73. 4:58you can barely see the little nubs,
  74. 5:00those kind of lifting lugs will touch the top of the arms and
  75. 5:06then it will hopefully not sheer off and crumple. Joe,
  76. 5:11is there anything you wanna add that, I dunno if you caught that,
  77. 5:13but I was just describing the landing sequence.
  78. 5:16Yep. That was accurate. <laugh>.
  79. 5:21We really hope it doesn't hit the tower.
  80. 5:24Yeah, exactly. And especially not that launch ring,
  81. 5:27which is really difficult to make that launch ring is very complicated.
  82. 5:33We have not found a reason yet why it will not work.
  83. 5:36Yes. Success is one of the possible outcomes. The probability is uncertain,
  84. 5:41but the, it is above zero. So the part of the, you know,
  85. 5:46like the arms are off to the side. So in theory,
  86. 5:48the booster is gonna come back and then when the engines start up,
  87. 5:52it'll translate over,
  88. 5:54slow down and translate over and get in between the arms,
  89. 6:00arms need to close and when they close,
  90. 6:02they need to close in such a way that they don't crush the rocket as well.
  91. 6:07Or score it all the way up the whole thing, just , <Tim noises>.
  92. 6:11Yeah. There's a lot of ways for this to fail.
  93. 6:13How quickly... Is it gonna close almost at the last second, like,
  94. 6:18or will it be mostly closed and there's a small tolerance there and it skirts
  95. 6:22the whole thing by, you know...
  96. 6:23It's intended to close on the methane tanks of the smooth,
  97. 6:26upper section about the top third of the rocket,
  98. 6:29and then you can keep translating down. And,
  99. 6:32and catch on those nubs that stick out the rocket.
  100. 6:35Yeah. I mean, if things are going right,
  101. 6:38it will actually look like the rocket is descending between the arms for quite a
  102. 6:43while. You know, cuz you gotta...
  103. 6:47The length of the thing is like basically around 70 meters.
  104. 6:51So you know, if you've got a descent rate of,
  105. 6:56I don't know, let's say two or three meters per second and you have,
  106. 7:01you know, 20 meters or something like that. It's okay.
  107. 7:05You're waiting for like 10 seconds. You know,
  108. 7:08<laugh> So it'll actually be like actually this is taking a while <laugh>.
  109. 7:13And now you gotta clear those chines too, you know,
  110. 7:16you can't have it be so close down on the...
  111. 7:18The chines will be clocked kind of away from the tower.
  112. 7:21So they won't be increasing...
  113. 7:23Oh, got it. The opposite way from the clamps. Got it. So as the, yeah,
  114. 7:28that makes sense. That's cool.
  115. 7:32But you still need to get the rocket has to still fit in between these arms.
  116. 7:38So, you know, it's still gotta come in
  117. 7:44and <laugh>...
  118. 7:45It has to center up and the arms will slew in...
  119. 7:47Yeah.
  120. 7:48...To meet it wherever it is.
  121. 7:49So if it's off to one side, it's gonna hit one of the arms,
  122. 7:52which will be quite bad.
  123. 7:54Yeah. <laugh>.
  124. 7:56<Laugh> yeah.
  125. 7:59<Laugh>.
  126. 8:00Or cook the arm or, you know, a bunch of bad things can happen.
  127. 8:04It's just insane though. I mean,
  128. 8:06it looks big from far away,
  129. 8:10but it looks even bigger when you're underneath it and you start to see almost
  130. 8:14the atmospheric distortion and the hazE <laugh> make it fade into
  131. 8:19the distance there.
  132. 8:21Yeah. I'm told this is the tallest thing south of San Antonio.
  133. 8:26Yeah. Because I think the other tallest was on South Padre.
  134. 8:29They have the hotel was the other tallest thing in the whole area here, so.
  135. 8:34And that's quite a bit taller.
  136. 8:37Actually booster and rocket are almost identical.
  137. 8:40At least the 120 meter version was like exactly the size of the Sapphire over
  138. 8:44there. So people need to know what that feels like.
  139. 8:47Just go up in the Sapphire and know that's how big this rocket is. <laugh>,
  140. 8:52which is insane to think about.
  141. 8:54Obviously you're not too worried about like the Human Landing System right now,
  142. 8:59compared to just getting things into orbit.
  143. 9:01But how is that has any of that stuff solidified yet?
  144. 9:05Like any of the Human Landing System?
  145. 9:09Uh, well, I mean, there's a lot of sort of design done on the computer level,
  146. 9:14but and there's some hardware, but, and our focus is getting to orbit, you know,
  147. 9:19if we can...
  148. 9:20Because human landing won't work without getting to orbit obviously.
  149. 9:22Yeah. We need Starship to get to orbit 'cause
  150. 9:28it's the only thing that can carry the Starlink 2.0 satellites. So,
  151. 9:31we've already produced the first, and we have on site,
  152. 9:35the first Starlink 2.0 satellite and it's seven meters long and Falcon has
  153. 9:41neither the volume nor the mass to orbit capability required for Starlink 2.0.
  154. 9:46So even if we shrunk the Starlink 2.0 satellite down,
  155. 9:48the total up mass of Falcon is not nearly enough to
  156. 9:53do Starlink 2.0.
  157. 9:54How heavy does one version 2.0 weigh?
  158. 9:57Well it's, it's about one and a quarter tons.
  159. 10:00There's so volumetrically huge that.
  160. 10:03Um, but if you just say
  161. 10:08like there's...
  162. 10:09A lot of people talk a lot about how many launches per year there are to orbit,
  163. 10:12but this is not really what matters.
  164. 10:14I think what really matters is what's the total useful
  165. 10:18payload to orbit per year. Cause otherwise you could say if this were
  166. 10:24ocean ships, you'd be like comparing a dinghy to a super tanker and it's like,
  167. 10:28they're not the same.
  168. 10:35For a satellite constellation,
  169. 10:36the thing that really matters is what is your total useful
  170. 10:40max mass flux to orbit. You know, so mass, you know, mass to orbit.
  171. 10:44So we need Starship to work and to fly frequently or
  172. 10:50Starlink 2.0 will be stuck on the ground.
  173. 10:53Wow. So that's your big motivator at this point is like get these things going.
  174. 10:55I
  175. 10:57assume because they're bigger will there have to be fewer of those to service
  176. 11:01the same amount of like area? Like is it gonna be,
  177. 11:04is version two gonna be in a higher orbit,
  178. 11:06servicing more people like with per satellite or is it just bigger so it has
  179. 11:10higher capacity, more bandwidth, more like all of that, I guess,
  180. 11:14compared to version one?
  181. 11:17Um,
  182. 11:17the Starlink 2.0 satellites are almost an order of magnitude more capable than
  183. 11:20Starlink 1.0.
  184. 11:21Bandwidth wise or total like throughput.
  185. 11:23I just think of it like how
  186. 11:26many useful bits of data can each satellite do Starlink 2.0
  187. 11:32in terms of useful
  188. 11:36bits of data is almost an order of magnitude,
  189. 11:41better than a Starlink 1.0.
  190. 11:44Are those different user terminals too, compared to...?
  191. 11:47The user terminals are on a separate upgrade path.
  192. 11:51Although user terminals will work with Starlink 1.0. or Starlink 2.0 satellites,
  193. 11:56but the Starlink 2.0s are just much more capable.
  194. 12:03Um, is it possible to go up in the tower, and do some or...?
  195. 12:06Um, I don't know. Can we go up in the tower? Is the elevator working?
  196. 12:10As long as the generator gone? Yeah. I can fire it up.
  197. 12:11Okay.
  198. 12:14I mean just might not be a bad place to watch a sunset at this point.
  199. 12:18Yeah.
  200. 13:16Where are y'all going to?
  201. 13:16Men's department!
  202. 13:21I guess we could stop at the QD arm and then, you know,
  203. 13:26then continue up.
  204. 13:28That will be and then...
  205. 13:39Yeah.
  206. 13:49This views gonna be insane. I can already get little sneak peaks through the...
  207. 13:54Danggg.
  208. 14:21Wow, this is epic.
  209. 14:23This is so epic.
  210. 14:24We're not even at the top.
  211. 14:26<Laugh>.
  212. 14:30Better enough. It's worth. This is where the QD arm is.
  213. 14:35Oh, hey.
  214. 14:37The top has a better view.
  215. 14:39Look at how beefy all this stuff is though.
  216. 14:42Yeah. I mean, this is insane, custom designed gigantic
  217. 14:48hardware. I mean it's hard to believe this is real.
  218. 14:52It genuinely is.
  219. 14:58Oh man. Geez.
  220. 15:10<Laugh> That's... It's quite the view.
  221. 15:14It's beautiful.
  222. 15:16Yeah. It's beautiful.
  223. 15:19We're even above the booster even right now.
  224. 15:23And we are in the sky.
  225. 15:31We can't even see South Padre.
  226. 15:34Oh, wow. Yeah. Really hazy.
  227. 15:41Well, should we go up?
  228. 15:41Yeah. <laugh>.
  229. 15:45Even better when there's a vehicle on the OLM.
  230. 15:47Oh, I know. I know. I can't imagine.
  231. 15:51Up close and personal. You gotta come back.
  232. 15:54Oh yeah. I missed the one... I came
  233. 15:59out here I think the day after you guys stacked. Well,
  234. 16:02I guess I came out for last event,
  235. 16:04but I think they stacked on like the 4th or not, don't know something.
  236. 16:07I don't what day it was. I was like next day. That's right.
  237. 16:29Emergency escape ladder thing?
  238. 16:31You can hand crank all the way down if you really lost power.
  239. 16:32I
  240. 16:45maybe want to do that once. It'd probably take like an hour. I feel like you...
  241. 16:53Holy crap. We're really getting up here though.
  242. 17:01The craziest thing to me is that none of this was here a year ago. You know,
  243. 17:05that's just hard to fathom is like,
  244. 17:07especially if you were out here three years ago and saw quite literally nothing
  245. 17:12but a field and a little R2D2 man. Wow, look
  246. 17:25at that.
  247. 17:31I mean it's far down there.
  248. 17:45If this isn't surreal. I don't know what is.
  249. 17:46Yeah, totally. It's insane. I mean, the Ship looks small from here.
  250. 17:51The ship looks tiny from here.
  251. 17:55Even people are like tiny. It's like, "Whoa".
  252. 17:59How tall is this again at this point?
  253. 18:01143 Meters at the top. Or about
  254. 18:06138 maybe?
  255. 18:14Oh my God. And look at how how hazy even the production site is right now.
  256. 18:19Yeah.
  257. 18:28This is not a good place if you have a fear of heights, that's for sure.
  258. 18:31<Laugh> You better go get over 'em real quick.
  259. 19:12Yeah. We should get like a hang glider and jump off or something.
  260. 19:15<laugh> That'd be sweet.
  261. 19:18<Laugh>.
  262. 19:19You could sell rides as a zip line over to the High Bay.
  263. 19:23You could probably zip line pretty far.
  264. 19:28I can't believe how small the boosters look from here even. That
  265. 19:35just looks... It looks so fake right now. This is insane.
  266. 19:42And just, we <laugh> how's that feel?
  267. 19:44Whoa. Vertigo.
  268. 19:48Oh my God.
  269. 19:52You see the ocean out there.
  270. 19:54We really lucked out on the on the night.
  271. 19:57The Gulf, I guess
  272. 20:03<laugh> Insane.
  273. 20:05It is insane. <laugh>.
  274. 20:08It is gorgeous.
  275. 20:10I think this is the time to be philosophical almost.
  276. 20:13It's just so inspiring out here, you know, it's... Do you,
  277. 20:18I mean, in your heart of hearts, like in the very depths of your soul,
  278. 20:21do you really believe this is like the start of making human Multi-planetary?
  279. 20:26I believe we have... I
  280. 20:29think for the first time it is possible.
  281. 20:32There's a possible outcome to make life multi-planetary.
  282. 20:36The key to making life multi planetary is a fully
  283. 20:42reusable rocket. That's the key.
  284. 20:44So full and rapid reusability, like an aircraft.
  285. 20:51So it's just very hard to achieve full reusability given
  286. 20:56the strength of Earth's gravity field and the density of the atmosphere.
  287. 21:01Full reusability would be, well,
  288. 21:04like relatively easy on Mars which has around
  289. 21:0937-38% of Earth's gravity and about 1% atmospheric density.
  290. 21:15It's just barely possible to achieve reusability on Earth. Like
  291. 21:20it's not as though, you know, all the, the rocket engineers in the past..
  292. 21:24It's not as though reusability never occurred to them. They, I mean,
  293. 21:28they're well aware of aircraft and other things. It's just that it's
  294. 21:33an incredibly difficult technical problem and
  295. 21:40they just thought it was
  296. 21:43impossible or the probability of success was so low that it was not worth doing.
  297. 21:50I
  298. 21:53feel like you almost had a bit of a Noah's Ark-esque you know,
  299. 21:56if you're gonna get Biblical, aspect at the last talk was saying how, you know,
  300. 22:00if you care about life and
  301. 22:03the true continuation of life on Earth and continuation of life as a
  302. 22:06consciousness, then you have to have a sustained planet, you know,
  303. 22:11another sustained planet off of Earth.
  304. 22:13Exactly. I mean, I think you know,
  305. 22:18if you think really long term, then you realize that eventually there
  306. 22:23will be some natural disaster even if it is not made by humans
  307. 22:28that destroys all life on Earth.
  308. 22:31So eventually the sun will expand and evaporate the oceans and
  309. 22:35and will be like Venus you know, just
  310. 22:40so hot that no life can really exist or maybe some chemotrophic
  311. 22:45bacteria, but eventually even they will, they will die.
  312. 22:48So the only way to prolong life,
  313. 22:51as we know it is for us to become multi-planetary and ultimately
  314. 22:56multi-stellar. And if
  315. 23:00we do not do that all life on Earth will die.
  316. 23:05So those who care about life on Earth should really care a lot about life
  317. 23:10becoming multi-planetary and ultimately multi-stellar.
  318. 23:13Well,
  319. 23:13I think there's a lot of people get attached to this idea that for some reason,
  320. 23:17you know,
  321. 23:18SpaceX or other aerospace companies are trying to escape Earth and escape
  322. 23:22Earth's problems. And I think you put it into a really good perspective that,
  323. 23:26you know, currently specifically like NASA's budgets, you know, 0.3% of the,
  324. 23:31you know, of the federal budget and then let alone, you know,
  325. 23:35the entire cost of how much we're investing so far in, you know, making,
  326. 23:40you know,
  327. 23:41getting humans off of Earth and protecting our planet even with asteroid defense
  328. 23:44and stuff is still relatively small. I think people don't understand that the...
  329. 23:48Oh yeah. So the Earth does not currently have any ability to stop
  330. 23:53asteroids now with Starship that we
  331. 23:59then have some ability to stop an asteroid. Actually,
  332. 24:02technically a comet would be the real danger because there are billions
  333. 24:07if not more than billions,
  334. 24:08maybe trillions of objects that are in the outer solar
  335. 24:13system some of them with that are very long period comments.
  336. 24:20An example that most people are probably aware of is Halley's Comet.
  337. 24:23So I forget the exact period is today but it's slightly under once per century
  338. 24:27that Halley's comment comes by. So
  339. 24:32there are probably many objects,
  340. 24:36many comments that have very long periods that we simply don't know exist and
  341. 24:42for example, the comet Shoemaker-Levy when that hit Jupiter,
  342. 24:49it made a hole in Jupiter, the size of Earth.
  343. 24:52So if that did hit Earth, that's "Game Over" everything's dead.
  344. 24:59So anyways,
  345. 25:03there's always some risk of such a thing occurring and the
  346. 25:12probable lifespan of life is just much greater if we're a multi-planet and
  347. 25:17ultimately multi-stellar civilization.
  348. 25:21Well, I think people also don't tend to realize that it's not a zero sum game,
  349. 25:24that if we're working on rockets and space flight and aerospace technology and
  350. 25:29all of these things, life support for these things, it's not just that you,
  351. 25:33you know,
  352. 25:33as company spend a hundred million dollars on a rocket and that a hundred
  353. 25:35million dollars went into space,
  354. 25:37it's that a hundred million went into the economy, you know,
  355. 25:41invested in our own technology, our terrestrial technology, you know.
  356. 25:45Look at all the spinoffs of NASA and what, you know,
  357. 25:47what NASA had done in the 60s and 70s to create the society that we live in
  358. 25:51today. You know, I mean, I think people are shortsighted sometimes on, you know,
  359. 25:56on the implications that you don't immediately see those things that you don't
  360. 26:00immediately grasp, because we they're just kind of unknowns at this point,
  361. 26:03you know?
  362. 26:04I mean, in general, the you know, the economy is
  363. 26:10very much a positive sum game, a kind of a growing the pie situation.
  364. 26:15When
  365. 26:20people examine their understanding or beliefs of the economy, if
  366. 26:25they have an implicit assumption that
  367. 26:30the economy is zero sum,
  368. 26:34then the only way for one person to get ahead is by taking things from another.
  369. 26:38But obviously the economy today is much,
  370. 26:42much greater than it was in the past. And we have the
  371. 26:49economic output per person is massively greater than the
  372. 26:54past. And
  373. 26:57so obviously what has happened is that the pie has grown and has grown much
  374. 27:01faster than the population has grown. You
  375. 27:07know, essentially if one creates wealth or creates
  376. 27:14great products and services that,
  377. 27:17that is something that should be applauded. That is, we've
  378. 27:24effectively increased the standard of living of,
  379. 27:31you know, of the country and perhaps of the world.
  380. 27:36The, you know, and sometimes people will conflate or you know,
  381. 27:41essentially
  382. 27:43they think of consumption and wealth as the same thing,
  383. 27:46but they're obviously not the same thing. You
  384. 27:51know, this is sort of a long argument of sort of capital allocation is
  385. 27:56a job consumption is fun, but capital allocation is a job.
  386. 28:02So anyway,
  387. 28:05I don't think a ton of people want say Warren Buffet's job,
  388. 28:08which is to read through very tedious annual reports of companies,
  389. 28:12including the minutia of the accounting and decide whether to
  390. 28:17invest in Coke or Pepsi. I don't want that job.
  391. 28:22<laugh>.
  392. 28:25I think aerospace in general kind of still follows the same, like, you know,
  393. 28:29if back in the day at one point, no one had electricity, running water,
  394. 28:33air conditioning, all of modern life's conveniences.
  395. 28:36And of course at first it started off as something that only a few people could
  396. 28:39get. And now it's, you know,
  397. 28:41a pretty common standard of living across the world. And, you know,
  398. 28:44you gotta start somewhere, same with air travel, you know?
  399. 28:46Yeah. Exactly air travel used to be accessible to almost no-one,
  400. 28:50to very few people. It was insanely expensive and dangerous.
  401. 28:53And now it is commonplace to fly somewhere. TVs
  402. 29:01used to be rare and expensive. And then, you know,
  403. 29:05big flat screen, plasmas used to be extremely expensive. And now you can buy,
  404. 29:10you know, go to Walmart and buy an amazing flat screen plasma for 500 bucks.
  405. 29:15It's amazing.
  406. 29:17Yeah, it really is.
  407. 29:19Yeah.
  408. 29:22Oh man. I don't wanna end the conversation on Walmart plasmas,
  409. 29:25but at the same time <laugh>.
  410. 29:28Yeah.
  411. 29:30Wow.
  412. 29:33It's a hell of a lot of progress.
  413. 29:36I mean, again, not to bring up the past, but three years ago,
  414. 29:38I think the first time I ever came out here was March, 2019.
  415. 29:42So almost exactly three years ago. And all you had was little hoppy.
  416. 29:47He had just made it out here and was starting to do some of the initial static
  417. 29:50firing. That was <laugh> that was three years ago.
  418. 29:53That's amazing that the, the hopper is still there.
  419. 29:56Yeah. Looking over us, all the grandfather, we all need.
  420. 30:01Yeah.
  421. 30:03But even, I mean, even the tank farm was like three tanks of those smaller,
  422. 30:07you know, for the first test,
  423. 30:08it was so tiny and there was literally just a dirt mound and three tanks.
  424. 30:13And now, you know,
  425. 30:14it's <laugh> and there was a tent out there and that was about it.
  426. 30:18Yeah.
  427. 30:19The propellant storage for the whole vehicle was actually,
  428. 30:24that was a really, that was a quite difficult,
  429. 30:28just put a lot of effort into the propellant storage.
  430. 30:33How? So if you have to scrub,
  431. 30:38if you're trying to do like the first static fires and stuff,
  432. 30:40how long does it take to recycle because you're probably...
  433. 30:43What's that look like?
  434. 30:44Because you have to drain the propellants back into the tanks and say,
  435. 30:48you have to come out here and wrench on something and you know,
  436. 30:50you have 33 engines that all have to work harmoniously.
  437. 30:53What's a scrub and recycle look like with this system right now?
  438. 30:58Well, first is gonna take us long time to scrub and recycle, but
  439. 31:03over time it should be very fast and we really shouldn't be scrubbing.
  440. 31:06It should just take off for it's like a normal thing.
  441. 31:08Yeah. But I mean, obviously the first,
  442. 31:10the first booster static fires will be probably...
  443. 31:13Yeah, no, I mean, it is gonna be very bumpy at first. I mean,
  444. 31:17for Falcon 9 in the beginning
  445. 31:21we'd have like a dozen recycles, like we'd scrub the launch like a dozen times.
  446. 31:24I mean, for a while there I was living out at the Cape,
  447. 31:29basically just working on,
  448. 31:32getting the damn rocket to take to, you know,
  449. 31:35getting all nine engines to start and take off and,
  450. 31:37and 'cause we would just have one launch abort after another.
  451. 31:43And I brought the kids with me and I went to,
  452. 31:45went to DisneyWorld a lot and Harry Potter land.
  453. 32:10Thanks again to Elon for all of your generous time and thanks to Ryan Chylinski
  454. 32:14with Cosmic Perspective, for helping to capture and share this conversation.
