Best moments from Elon Musk's Starship update

Science
Speaker 1: The the sales pitch for, for, for going to Mars is that, um, it's gonna be a cramped, dangerous, difficult, uh, very hard work. Uh, you might die. Um, and, um, that's the sales pitch. I hope you like it so far from being some sort of escape hatch, it will be extremely difficult and dangerous and, and tough. [00:00:30] Um, Speaker 1: Mars, Mars is a fixer upper of a planet. And, um, so it's, it's gonna take some work to make it, make it easy to live there, but at one day we could make Mars a planet like earth, and I think we should. The, the critical threshold I think for Mars is to, uh, have a city that is self-sustaining. Um, it's gonna be incredibly difficult to make a self-sustaining city because if it's missing any ingredient, any ingredient [00:01:00] at all, um, however, minor that ingredient is then if the ships from earth stop coming for any reason, uh, the city will die out. Starship is capable of doing that. It's capable of, of getting, getting a million tons, the surface of Mars and creating a self-sustaining city. Um, and I think we should try to do that as soon as we can. Um, the window of opportunity may be open [00:01:30] for a long time and I hope it is, but it, it may also be open for a short time. And this is the first, this is the first point in the four and a half billion year history of earth that it has been possible. So the, and, and we're aiming for, uh, rapid reusability, uh, which is why the, the booster is, is gonna take off and then fly back to the launch tower and, uh, aspirationally, uh, get, uh, land [00:02:00] on the arms if it does come in too fast. Um, and, um, and sheer off the arms, then I guess it will be a farewell to arms. Speaker 1: Uh, there'll be more ships than there are boosters because the, the booster actually, even though it's gigantic, uh, will come back in about six minutes. The, the, the ship, uh, has to complete at least one orbit around earth and sometimes, uh, maybe three orbits or, or more, uh, and each orbit is 19 minutes. [00:02:30] So the ship, uh, is probably, you know, reusable about every, uh, six, six to eight hours. That's, uh, that's why we say sort of three times a day for the ship. And in theory, the, the booster is capable of being, uh, reused every hour. Um, so that the, the propelling pumps are designed to fill the rocket in, uh, about half an hour. So the, this really is designed for rapid reusability, [00:03:00] just some facts about Starship and these, these numbers will evolve over time. Um, so, uh, the Heights of the ship is about 50 meters, 164 feet, uh, the nine meter or 30 foot, uh, diameter. Speaker 1: Well, you can just see it basically. Um, um, it's got about 1200 tons of, of propel on the, the ship and, uh, thrust is about 1500 tons. Um, now these numbers will, yeah, we'll probably add more propel [00:03:30] over time, increase thrust. Um, diameter will, will stay the same. It's a huge, huge pain to change diameter, so that that'll tend to stay the same, but it'll probably get a little bit longer. And, uh, we're expecting payload capacity of, uh, a hundred to 150 tons depending on, on which orbit. Um, so to, uh, to a Starling orbit, uh, roughly a hundred tons, uh, heat shield. So this is the world's largest heat shield. Um, and, uh, this is, uh, we actually, you make this [00:04:00] at, uh, at our little factory in, in Florida near Cape canal. Uh, we call it the bakery and, uh, we're actually using a lot of techniques that are, uh, used for roofing tiles. Speaker 1: So we, we need to have a heat shield that, uh, is capable of resisting extreme heat, but also is not a crazy expensive. And, um, our heat shield team has done, done amazing work in creating, uh, the world's largest, uh, heat shield and one that is, uh, reusable, uh, but also, uh, robust and, [00:04:30] uh, low cost. So, uh, it's not a, it's not a crazy money heat shield that that's one of the technologies that is necessary for, um, getting to Mars. So, uh, the ship would get to orbit with, with payload and then in orbit, we would refill the tanks. So it'd have enough repellent, uh, to, to get to Mars. Mars is far so let's see super, the super heavy booster. So it, it was 17 meters. Um, but then [00:05:00] there was an extra half barrel section that the team deleted and totally accidentally at 69 meters. Speaker 1: It's also booster four inch ship 20. I mean, this is a pure coincidence numbers. Won't leave me alone. Just, um, I hope it's good luck. Um, so yeah, so, so propelling capacity is like around 3,400 [00:05:30] tons. I think this, like I said, these, these it'll probably, uh, it will increase over time, probably get to 36, maybe 3,800 tons. Um, thrust is around 7,600 tons. Uh, that'll probably increased through over time. Um, just to put this into perspective though, the Saturn five was, uh, seven and a half million pounds of thrust and, um, Starship is 17. So it's more than twice the thrust of a Saturn five, which was quite, that was that's the largest rocket ever to get to all it, [00:06:00] um, yeah, worth noting, super heavy is, is the, the largest flying object of any kind or will be the next booster. Uh, we actually increased the engine count to 33. Speaker 1: We've kind of bounced around on engine count. Um, but, um, it, cause I think at one point we had like 37 engines and, uh, they were into 29. Uh, we finally settled on, on 33 engines, which, which is about actually the most number of engines you can actually fit under that, that booster without like expanding the [00:06:30] diameter. Uh, this, this tower from, from design to construction was, uh, 13 months. So it's quite an quite an epic structure. Um, it it's really worth emphasizing that the, the whole launch system, which is basically stage zero, uh, is, um, I'd say as complex and difficult as either the booster or the ship. So I, I really want to emphasize that this is, uh, and it's [00:07:00] a very difficult thing that requires a lot of hardcore engineering and, uh, it's really, um, like I said, the, the tower and the launch system, which I call stage zero is just as important as stage one and stage two. I mean, this is really some, some wild stuff year in fact, I mean, hard to believe it's real except, you know, Right there. So, Speaker 1: [00:07:30] And then rafter development, uh, R one was 185 tons of thrust. Uh, rafter two is 230 tons of thrust. And I think over time, uh, we can get that to probably 250 tons. Um, so that's, and it's also significantly simplified. So you can see the difference between V one and V two. So it's it actually, um, Raptor two cost about half as much as R one, despite having [00:08:00] much more thrust. Uh, and I think just generally being, um, a, a much easier engine to build, uh, and a more robust engine. So, um, very excited about Raptor version two, and it's, it's only gonna get better from here. Yeah. [00:08:30] So yeah, so Raptor two is pretty sick. Um, we have so upcoming, uh, uh, Starship mission, uh, orbital flight is really just the beginning. Uh, so we're, we're, we're gonna have, um, a number of Starlink, uh, missions, uh, that will launch, uh, Starlink satellite version two. Um, but, uh, even more exciting than that is the, the NASA, uh, [00:09:00] human space flight mission. Um, we're incredibly honored to that that NASA has selected, uh, Starship to, uh, take astronauts back to the moon for the first time in, in half a century, which is kind of mind. Speaker 1: I'd just like to say, like we're, we're SpaceX is just deeply honored and appreciative that that NASA would, would, uh, uh, choose us for, for this, uh, [00:09:30] incredibly important mission. And, um, we'll get it done. Um, and then there, there's also, uh, the dear moon mission, which is, uh, um, uh, gonna take, um, artists around the moon and, um, that's, uh, saku Meza and he he's, uh, gonna select, uh, I think a dozen artists and, um, and, and do a loop around the moon, which will be very exciting. And there's gonna be some, uh, future announcements [00:10:00] that I think people will be pretty fired up about. So, um, anyway, super exciting future ahead with, uh, this, uh, there'll probably be a few bumps in the road, you know, but, uh, we'll wanna iron those out with, uh, satellite missions and test missions and, and, uh, and get to a high flight rate and, and then have something that's extremely reliable, uh, for, for human face flight.
