    Quote Posted by Miller (here)
    Tech entrepreneur Elon Musk has revealed he has Asperger's syndrome while appearing on the US comedy sketch series Saturday Night Live (SNL).

    The 49-year-old told viewers he was "the first person with Asperger's" to host the long-running programme - to loud cheers from the audience.

    People with Asperger's interpret the environment around them differently to other people.

    It is thought to be the first time Mr Musk has spoken about his condition.
    Ha. Very very interesting, and I totally never knew that. The BBC article you cited was 2 years ago.

    But I've had some personal experience with people with Aspergers, and hearing Elon in that audio conversation it became very clear. It's worth listening to (just a few minutes anywhere in the stream), and the symptoms are right there.

    They can be exceptionally intelligent and able, are often extremely good at processing information, and can hold down high-level positions easily. But when they're a little stressed, distracted, or for some reason not feeling totally on the ball, they can go way out of whack — or even way off the rails! — rather more easily than other people.

    This would be very interesting for armchair rocket geeks (and no-one else! ), a detailed live audio-only Q&A held with Elon Musk 12 hours ago about what the heck really happened with the last Starship launch.

    I've posted it here not for the engineering discussion, but because I was astonished how truly terrible Elon was when trying to explain things to others, even when his audience was fairly well-informed. Maybe he was stressed, completely unprepared, or hadn't had enough sleep, but he was just so totally inarticulate it really surprised me.

    As an aside (but the discussion doesn't really belong on this thread!), he seemed to me to show every symptom of being on the autistic spectrum — which I'd now guess he probably is, as a high-performing Aspergers. Listen in for a couple minutes at almost any point, and you may be able to see this clearly.

    https://m.youtube.com/watch?v=mmIqSPux3FY
    Much thanks, Bill, for posting this audio Q&A. My previous questions about the launch pad, and their way forward, were answered and informed. Learned lots else, too.

    Shoutout to co-host Everyday Astronaut. He has done several really interesting 1-1 interviews with Elon, getting to a level of technical/engineering that I have rarely heard and often missed.

    I kept listening for Elon to falter, and came up empty. Probably just me having hardwired filters for his kind of lurching gait of talk. One of my drilling-rig crews called me Lurch, after the Addams Family character. I thought it was about my awkward walking gait across the frozen uneven mud of the lease/location, but now I’m not so sure. A crew on a different rig called me “Johnny-5” lol (an ~autistic robot in a movie (which I had seen)), and I didn’t figure that out until later.

    • Starship Vs N1... Is Starship "Doomed" To Repeat History?

    Has SpaceX fallen into a similarly flawed design that plagued the N1? Why did they choose so many engines? Will it continue to suffer a similar fate over and over like the N1 or is there something inherently different?

    Today we’ll answer those questions and compare the two most powerful rockets ever made, from different sides of the world and from completely different eras to figure out how they’re similar and perhaps more importantly, how they’re different.

    00:00 - Intro
    01:50 - Starship VS N1
    04:40 - Comparing engines
    06:25 - Common philosophies
    14:30 - Trial by flying
    19:55 - Will starship repeat history?
    26:20 - My opinion / Summary

    On April 20, 2023, SpaceX’s Starship and its Super Heavy booster broke the record set by the Soviet Union’s N1 rocket, becoming the world’s most powerful rocket. Despite the differences in time and geography, these two rockets share striking similarities. In this article, we will explore the parallels between the N1 and Starship, analyze their designs, and examine the reasons behind their engine choices. Additionally, we will discuss their respective capabilities and the philosophies that guided their development.

    Let’s begin by comparing the N1 and Starship side by side. The N1 was the Soviet Union’s ambitious attempt at a moon rocket, aiming to rival the United States’ Saturn V. It was an enormous rocket, measuring 17 meters in width at the base, tapering up to six meters in width for the upper stages, and towering at an impressive height of 105 meters. When fully fueled, it massed 2,735 metric tonnes.

    In contrast, Starship is even taller, standing at 120 meters, with a width of 9 meters for both stages. However, what sets Starship apart is its weight when fully fueled, which reaches approximately 5,000 metric tonnes—nearly double that of the N1. Starship’s design enables it to carry up to 150 tonnes into low-Earth orbit, making it the most capable rocket ever built.

    The N1 employed kerolox, a combination of RG-1 and liquid oxygen, as its propellants. Starship utilizes methalox—a mixture of liquid methane and liquid oxygen. Another distinction lies in the number of stages, with the N1 having a minimum of three stages, but for lunar missions, it utilized up to five stages, similar to the Saturn V. In contrast, Starship is a two-stage rocket, comprising the Super Heavy booster stage and the Starship upper stage, both of which are designed to be fully reusable.



    Starship vs N1. (Credit: Everyday Astronaut) Perhaps the most prominent similarity between the N1 and Starship lies in the number of engines they employ. The N1’s Block A first stage featured 30 NK-15 engines, while the Starship’s Super Heavy booster boasts 33 Raptor 2 engines. The N1 had additional engines on subsequent stages, whereas Starship relies on a combination of three sea-level Raptors and three vacuum-optimized Raptors on its upper stage. However, it’s important to note that these engine configurations for Starship are subject to change as the rocket is still in development.

    The NK-15 engines on the N1 Block A Booster utilized an oxygen-rich closed cycle, a technology the Soviets had mastered in the early 1960s. These engines produced 1,526 kN of thrust and had a specific impulse of 297 seconds at sea level, with a mass of approximately 1,250 kg. The Raptor 2 engines on Starship produce 2,255 kN of thrust and have a specific impulse of 327 seconds at sea level while massing only 1,600 kg. Consequently, the Raptor 2 engine has a superior thrust-to-weight ratio of approximately 144:1 compared to the NK-15’s 122:1 ratio. This means that not only is the Raptor 2 more efficient and produces more thrust per kilogram—a crucial advantage.


    • Philosophies
    One common question people have is why these rockets have so many engines. Doesn’t more engines mean more potential points of failure and a more complicated system? While it’s true that more engines have the potential for more failure points, there are several advantages to having many smaller engines.

    One advantage is that the loss of an engine has less impact on total thrust levels with many smaller engines compared to fewer larger engines. For example, the N1 rocket had 30 engines producing 45 MN of thrust, while the Saturn V had 35 MN of thrust from just five engines. If one engine failed on the Saturn V, it would result in a 20% loss of thrust, potentially jeopardizing the mission. In contrast, losing one engine out of the N1’s 30 engines would only result in a 3% loss of thrust, which is within acceptable margins to continue the mission.



    Additionally, a larger number of engines can provide more robustness in the event of an engine failure. Although more engines increase the chances of failure, having multiple engines allows the rocket to continue operating even if one engine fails. SpaceX’s Falcon 9 rocket, which uses nine smaller engines, has demonstrated this reliability, with only two engine shutdowns during ascent that did not result in mission failure. Moreover, SpaceX’s Falcon Heavy, equipped with 27 engines, has maintained a flawless record of mission success.

    To enhance reliability, each engine can be enclosed in its own blast containment shield, preventing a catastrophic failure from affecting neighboring engines. SpaceX has implemented improvements in blast containment shields for their Super Heavy boosters to enhance safety.

    Aside from operational advantages, many small engines offer cost benefits and easier handling. The economies of scale come into play when producing a larger number of smaller engines, allowing for quicker depreciation of research and development costs. SpaceX has already achieved significant cost reductions in engine production, with the Raptor 2 engines costing less than $1,000,000 each, compared to the F-1 engine on the Saturn V, which cost approximately $115,000,000 per engine in today’s currency. Smaller engines are also less prone to combustion instability issues that larger engines can face.
    Furthermore, the smaller size of engines makes them easier to handle, test, install, and transport. Higher production rates and more frequent testing provide more opportunities to identify flaws and make improvements in manufacturing. With several smaller engines, there is more testing time available to refine the engine design and ensure reliability.

    Although the initial flights of Starship showcased some engine issues, SpaceX has produced over 300 Raptor engines and implemented a more rigorous testing regime, aiming to achieve outstanding reliability. The decision to fly early versions of the rocket, despite lower success probabilities, is driven by the pursuit of learning and improving the system, similar to the approach taken by the Soviet Union with the N1.
    • Trial By Flying
    The Soviet Union had limited options with the N1 rocket due to its inability to conduct thorough static fire tests. They couldn’t even test fire each individual engine, as the NK-15 engines used pyrotechnics to open valves, rendering them single-use. Instead, they opted to test only one in every six engines (many places online say one in every three, which is incorrect) to identify general production errors. Consequently, the engines used in the N1 flights were not test-fired before launch. This compelled the Soviets to rely on launch tests as the only means to evaluate the N1’s performance.



    Similarly, SpaceX chose a similar philosophy of iterative testing with Starship, despite conducting engine tests and static fire tests. They believe that testing, even if it fails, provides valuable data and insights. Rather than trying to solve all the complexities of flying, landing, and reusing the world’s largest rocket in one go, SpaceX adopts a step-by-step approach, learning from each test.

    The first integrated test flight of Starship aimed to clear the launch pad without catastrophic failure, although it did result in violent concrete ejections that damaged parts of the complex. Nevertheless, the flight validated various aspects, including passing through Max Q, testing the heat shield tiles under strong wind shears, and confirming the functionality of systems and equipment. SpaceX gained real-world experience and identified areas for improvement, such as the flight termination system.

    The question arises: Why did both SpaceX and the Soviet Union opt for this iterative design process instead of thoroughly engineering and testing each part for high success rates on the first flight? The answer lies in the differences in their contexts. NASA’s SLS rocket, for example, underwent extensive testing and engineering over 12 years, aiming for flawless performance to avoid cancellation. The SLS achieved a high degree of success on its first launch, but at a significantly higher cost.

    On the other hand, Starship began its engine development in 2016 and became a full-fledged project at SpaceX around the same time. It took seven years to conduct the first integrated flight test, and the rocket is still far from operational. However, the iterative process allows for rapid production, evolution, and improvement of Starship, positioning it for operational status in the future.

    SpaceX follows a “build fast, test, break stuff, iterate, fly, blow stuff up, learn from it, repeat” approach, akin to the Soviet Union’s philosophy. While the N1 faced a different fate, Starship’s future remains uncertain. However, considering its potential for operational capabilities, continued improvement, and adaptability, Starship is poised to carve its own path and achieve success in the years to come.
    • Will Starship Suffer The Same Fate?
    The failure of the N1 rocket cannot be attributed solely to the number of engines it had. While the number of engines played a role, the root cause of failure was primarily the quality of the NK-15 engines. These engines were relatively new, untested, and prone to failure. The lack of testing for both the engines and the full first stage, coupled with the use of a primitive computer system called KORD to manage the numerous engines, created a recipe for disaster.



    Thrust differential, the mode of steering used by the N1, also posed challenges. It required precise throttle commands and resulted in more time spent in transients as the engines throttled up and down. If an engine shut down, the KORD computer had to shut down the opposite engine to maintain equal thrust. This meant that the N1 could only afford to lose two engines since each shutdown required the opposite engine to be shut down as well, leaving little room for error.

    In contrast, Starship’s Super Heavy booster primarily steers through the center 13 engines, which are capable of gimballing. Gimballing allows the engines to swivel and provide pitch, yaw, and roll control. The Raptor engines used in Starship have an impressive gimbal range of 15 degrees and can make rapid adjustments using electromechanical servo thrust vector controls. This means that if an engine fails, Starship can maintain control by adjusting the gimbal angles, without needing to shut down opposing engine pairs.

    Despite the challenges faced by the N1, it is believed that they would have eventually resolved the issues and improved the rocket’s performance. The N1-F, the next iteration of the N1, was expected to feature upgraded and more reliable engines, the NK-33.
    Starship benefits from over 50 years of advancements in computer and aerospace technologies. Modern computers allow the engines to detect anomalies and shut down before catastrophic failure occurs. Furthermore, SpaceX has a solid revenue stream from being a leading launch provider and rapidly expanding its Starlink internet service. They are investing significant resources into Starship and have the goal of mass-producing the rockets. SpaceX’s track record of achieving once thought-impossible feats and its commitment to innovation make them less susceptible to running out of funds or facing untimely setbacks.

    SpaceX is already developing multiple facilities to scale up Starship production, and there are several vehicles near completion. While they currently lack a working launch pad, it is reasonable to believe that SpaceX will find a solution. It’s important to note that these assessments are not biased but based on SpaceX’s demonstrated ability to overcome challenges and accomplish remarkable feats in a relatively short period.
    • Summary
    In summary, while the N1 faced significant difficulties, Starship has the advantage of technological advancements, financial stability, and a proven track record of pushing boundaries. SpaceX’s commitment to iterative design, economies of scale, and reusability positions Starship for success and the potential to revolutionize space transportation.

    • SpaceX's NEW Raptor Engine is Mind-blowing:

    Starship, SpaceX’s mars bound rocket is set to receive a huge update as its engine raptor is getting a remodel, promised to bring a monumental revolution. In fact, it’s a big boost to power to become the most powerful engine ever built. Yeah, SpaceX just shocked the whole rocket industry with NEW ENGINE - Raptor 3. How does the Raptor 3 stack up against other engines? And how will this enhancement impact SpaceX's future? Analyze everything about this in today's episode of Alpha Tech: SpaceX CEO Elon Musk had set his goals for Mars since the company’s conception in 2002, initiating a stepwise process beginning with uncrewed flights of the small Falcon 1 before upgrading to commercial missions with the larger Falcon 9, followed by crewed flights to near-Earth space and heavy-lift missions of the Falcon Heavy, including precursor missions to Mars. Achieving this ambitious goal requires a massive launch vehicle with a cluster of high-powered engines, a propulsion system for operating in deep space, and a propulsive landing and ascent architecture for operation in the Martian atmosphere. SpaceX's NEW Raptor Engine is mind-blowing than you think!

    • SpaceX's Radical Starship Design Change: Hot Staging Confirmed!:

    How will the second Starship flight differ from the first one? Did SpaceX and Elon Musk just confirm our speculations about Starship hot staging? Who was selected for the Crew 7 mission? And did Vulcan get delayed… again?

    ¤=[Post Update]=¤

    • Musk just revealed Starship's hardest technical problem...:

    Elon Musk just revealed Starship's hardest technical problem SpaceX is going for a second try to launch its Starship to orbit, but don't get your hopes up too high. There's still a 40% chance of a big boom, which is only slightly better than the previous attempt. The key factor is how well they can pull off the stage separation, which involves igniting the upper stage engines while still attached to the booster. Sounds crazy, right? Even Elon Musk thinks so. He said it's the most risky thing for the next flight. But why do they do it? Find out everything you need to know about Starship's toughest challenge in today's episode of Alpha Tech!

    • Elon Musk just revealed Starship NEW major DESIGN upgrades to reach orbit:

    Elon Musk just revealed Starship NEW major DESIGN upgrades to reach orbit. SpaceX just pulled off a stunning feat with its newest Starship prototype, Ship 25. For the first time ever, the massive rocket fired up all six of its Raptor engines in one go, without any prior tests. That's right, no warm-ups, no rehearsals, just pure rocket power. This is a huge milestone for SpaceX, as it shows how much confidence they have in their Starship design. You may remember that two months ago, SpaceX launched its first Starship orbital flight, which was a historic achievement in itself. But since then, they have been busy making over 1,000 improvements to the next version of Starship, which is now ready to take to the skies. So, what are some of the changes that SpaceX has made to Ship 25? And what are their plans for the future of Starship? Stay tuned as we dive into these questions and more in this episode of Alpha Tech! SpaceX took the first step towards another highly anticipated orbital test flight later this year after it conducted a static fire of the Starship second stage spacecraft yesterday. The test was a success and SpaceX soon confirmed on its Twitter later on that the test was a success with 6 engines fired on Ship 25. While Ship 25 does not feature many upgrades over Ship 24, its upcoming flight is certainly no less exciting as the Starship S25 introduces a range of modifications that enhance its functionality and performance. Musk outlined some of the Starship rocket modifications in a Twitter Spaces discussion on Saturday with journalist Ashlee Vance.

    • SpaceX's Starship Interior Design NEW UPDATE!

    On April 20, Starship achieved a significant milestone thanks to its first test launch, an undeniable feat. This accomplishment has provided SpaceX with valuable data to further develop the Starship for critical future missions, particularly those involving human passengers. But just a spacecraft that can fly won't mean anything to Elon Musk's goal of colonizing Mars, Starship also requires to have a meticulously planned and designed interior space to cater to extended-duration stays. That's something they've changed! Nick Cummings, senior director of SpaceX, recently unveiled an exciting revelation about the interior design of the Starship that includes a host of features and amenities guaranteed for an enjoyable trip to any celestial destination.

    • Why Starship's 1st to orbit is even more important than SpaceX thinks!:

    In South Texas, the commercial spaceflight company SpaceX is preparing to test a huge, stainless-steel rocket. The machine could one day carry humans to the moon, Mars and beyond. But before any of these big dreams can happen, SpaceX needs to prove that Starship can actually reach orbit. Yeah, Starship's 1st to orbit is even more important than SpaceX thinks... First up, experts are calling this a testament of the tireless efforts of SpaceX engineers, which spans over a decade. They have been working day and night just to see Starship reach orbit. It all started with a 2012 announcement of plans to develop a rocket with substantially greater capabilities than SpaceX's existing Falcon 9. It was underpinned by the ambition to enable human exploration and settlement of Mars. The company would go on to create a succession of designs for such a vehicle, under various names like Mars Colonial Transporter, Interplanetary Transport System, and BFR. It all led up to a 2019 adoption of a stainless-steel body design, which is also when the name changed to the current Starship. Why Starship's 1st to orbit is even more important than SpaceX thinks...

    • Unleashing the Power of the Mars Cycler: SpaceX Starship to play a huge part?:

    If you’ve been watching along here for quite some time, you will know that the team and I have been releasing some deep dive videos that look into the complexity of long duration crewed spaceflight. The primary concerns of course being the health of astronauts aboard these missions. To do all of this stuff right and protect those squishy fragile human bodies on board, it is going to take a lot of equipment. That also means a lot of mass. Well, here we explore Unleashing the Power of the Mars Cycler. Would SpaceX Starship to play a huge part? Almost certainly if SpaceX's dreams of low mass to orbit become reality. What if I told you, that once we get all this up to the required speed for the journey, that was it. A reusable station taking trip after trip, only needing tiny course corrections from time to time? Well, with a nod to Buzz Aldrin, may I present to you the Atomic Powered, Shielded, Spinning Starship Mars Cycler!

    My assessment of the space x starship is that it has primarily been developed to take the Starlink V.2 satellites into orbit. I do not believe this design is optimal for a moon or Mars launch. The Mars story is a great deflection to stop people from asking why these satellites have become so massive if they are only to bring internet to rural locations.

    Star wars (SDI program)?

    See my thread on this subject
    https://projectavalon.net/forum4/sho...ecame-Starlink

    Starship "is the only thing that can carry the Starlink 2 satellites. Falcon has neither the volume nor the mass-to-orbit capability required for Starlink 2."

    During that same interview, Musk explained that the next-gen satellite will measure roughly 23 ft (7 m), weigh roughly 1.25 tons (roughly 2,750 lb), and will be "almost an order of magnitude more capable" than current "Starlink 1" satellites — though he didn't specify whether he was referring to bandwidth or throughput.

    Musk also explained that Starlink 2.0 would be roughly four times heavier than V1.5 and just under five times heavier than V1.0.

    • Elon Musk And Nasa Finally Revealed Plans For New Space Station!

    You've probably heard about SpaceX's intentions to utilize its enormous new Starship spacecraft to send several Starlink satellites or huge telescopes into orbit, land people on the Moon and Mars, transfer equipment or people between points on Earth at a fast rate of speed, or even all of these things. But, wait! SpaceX previews another Starship application. And in today’s episode, we’re going to find out how they'll make this happen?

    Hello everyone! Welcome back to Elon Musk Evolution, where we bring you the most recent news about Elon Musk and his multi billion-dollar companies, space news and the latest science and technology.
    But, before we begin, make sure you subscribe to our channel and click the bell icon so you don't miss any of our amazing videos.
    NASA is on board to provide expertise as the business explores another use for the Starship architecture developed by SpaceX. Though the technology is still in its infancy, NASA is keenly interested in this project because it could turn Starship into a commercial space station, as there are currently no plans for a government-owned research facility in low-Earth orbit after the International Space Station is shut down in 2030.

    A new series of agreements with seven private companies, including SpaceX, were revealed by the space agency last month. The Collaborations for Commercial Space Capabilities (CCSC) program was created to encourage the private sector's development of cutting-edge goods and services that might be made accessible to clients in five to seven years, including NASA.

    This is distinct from the sponsored contracts NASA entered into in 2021 with three business teams led by Nanoracks, Blue Origin, and Northrop Grumman, who are all developing different ideas for a commercial space station. Axiom Space, a different business, has a contract with NASA to create a commercial module that will be attached to the International Space Station with the intention of using it as the focal point of a privately owned complex in low-Earth orbit in the future.

    NASA rejected SpaceX's proposal for a sponsored space station development agreement in 2021 due to concerns over, among other things, SpaceX's intentions to scale up its life support system to permit long-duration missions and its single docking port. The new CCSC initiative, which incorporates the Starship space station concept, is not being funded by the space agency, but the government will help the industry with technical know-how, including expert assessments, lessons learned, technologies, and data.

    Along with the SpaceX agreement, NASA also announced it will back Blue Origin's effort to create a crew spaceship for orbital trips that would launch on the firm's New Glenn rocket. The organization also supports Northrop Grumman's efforts to create a research platform in low-Earth orbit that will be manned and work in tandem with the company's proposed space station.

    The other businesses chosen by NASA for unfunded agreements included: Sierra Space's proposal for a crewed variant of its Dream Chaser spacecraft; Vast's idea for a privately owned space station; ThinkOrbital's plan to develop welding, cutting, inspection, and additive manufacturing technology for construction work in space; and Special Aerospace Services for collaboration on an autonomous maneuvering unit to help, or perhaps even replace, spacewalkers working outside a space station.

    • SpaceX's Remarkable Full Pressure Test, Starship Sacrificed, & Record Breaking Falcon Heavy Mission:

    We’ve got it all today my friends. SpaceX's Remarkable Full Pressure Test of the water cooled steel plate system, another favorite Starship Sacrificed. 🥺 A Record Breaking Falcon Heavy Mission, testing for the first time on Starbase's Orbital Launch Mount. Falcon 9 action as always with 2 Starlink flights, some neat perspectives from Hubble, and can Amazon's Project Kuiper really compete with Starlink? They sure think so based on the construction plans breaking this week.

    Elon's simple statement:
    Starship is ready for launch
    Awaiting regulatory approval
    The regulatory approval is that of the FAA, who were obliged to look into the events of the previous Starship launch, which created a dramatic tornado of concrete debris all over the launchpad and way beyond. (But all that's been fixed now. It can't and won't happen again, which should be easy for the FAA to understand and agree.)

    FAA approval might be hours, days or weeks away. But there's speculation it's going to be pretty soon, a green light being given suddenly and without any warning. Once that happens, the next flight would follow in a few days at most.
