| |
| ▲ | coldpie 4 days ago | parent | next [-] | | Yeah. I used to be excited about SpaceX stuff, I remember watching those early livestreamed landing attempts. But their recent close association with the American fascist movement basically killed my enthusiasm. I can't support the company anymore. | | |
| ▲ | idiotsecant 4 days ago | parent [-] | | Elon Musk is one nepobaby with poor emotional regulation. SpaceX is an enormous number of very smart, very driven, very dedicated professionals who all work ridiculous hours in not great working conditions because they believe in the outrageous idea of humanity out among the stars. It's ok to not like the guy at the top, but still marvel at the achievements of the people he pays. | | |

There are many important and meaningful jobs out there that those people could be doing, which don't involve giving financial & political power to one of the worst people alive today. Choosing to work for him after the many, many, many red lines Elon Musk has crossed taints all of the work those people are doing. | | |

| ▲ | FridayoLeary 4 days ago | parent | prev | next [-] | | You don't give him enough credit. No one else was lunatic enough to back spaceX and build it into a genuinely innovative and successful company like he has. Of course he had a leg up but i see in him a genuine drive to succeed. He thinks he can do things better then anyone else, and in some ways that's true and he gets frustrated when things don't go his way. You see the same sort of thing in F1 drivers. Even in the most casual of driving competitions they are competetive to the point of pettiness. My theory is that's part of what makes them an F1 driver - the inability to lose. it can easily be turned to destructive purposes, see all the avoidable crashes but it gets harnessed and turned to useful purposes. On a more loaded tangent, see Trump. His lifelong ambition was to be famous and become president and i thinkthat, more then his billions gave him the drive to run for office and get reelected (you can argue that it was to satisfy his overwhelming ego but that doesn't change my point). Even if you despise them and everything they stand for i think everyone can learn something from them in how to succeed in their goals. it's not being narcisstic and elbowing everyone out of the way, but it is about having goals, wanting them enough and a healthy dose of self belief. | | |
| ▲ | idiotsecant 3 days ago | parent [-] | | Elon Musk's primary contributions to his companies are funding them and staying out of the way. When he gets involved in actually leading them bad things happen. See: Twitter. | | |
| ▲ | panick21_ a day ago | parent [-] | | People have gone off the deep end on this. Its just factually false by every historical fact we know. He does not 'funding and staing out', that's mostly the opposite of what he does. That's just an objectively false claim. And if you actually study SpaceX and Tesla, then you figure out that they are actually very smart with their capital investments, and therefore didn't need nearly as much funding as his competitors. And not being able to do one thing, running twitter, doesn't mean magically that its the same at other companies. Morris Chang failed at running a consumer facing job at TI but do we therefore conclude that he is bad? |

Especially if you think they're Nazis. SpaceX exists because the US wants access to space and they are the cheapest way to space in history. They can continue to exist because starlink and their commercial launch services are massively profitable. | | |

You didn’t call out anything substantive in my previous comment so I’ll assume those points are not disputed. As to the profitability of Starlink: > Starlink is projected to generate between $11.8 billion and $12.3 billion in revenue in 2025, according to analyses from Quilty Space. This projected growth is driven by increasing subscriber demand and significant government contracts, particularly with the U.S. military. You’ll likely find similar when looking up SpaceX profitability in 2025. So, again, these things only exist because of the US government. Do we agree on this yet or do we need to delve further somehow? | | |

If you read carefully you'll see that I said that SpaceX would not have existed from its conception if not for the US government. But I asserted that it is no longer necessary and that is absolutely true. You pointing out that a basket of money includes dollars from the government (i.e. starlink revenue) doesn't even come close to disproving that. Google gets paid from government contracts too and their existence is not contingent on those contracts. This conversation is over. I hope you will investigate facts and appreciate nuance more in the future. | | |

| ▲ | pythonaut_16 4 days ago | parent | prev | next [-] | | "Even if it never reaches orbit reliably" How is that a greater achievement than Falcon 9 and reusable boosters, especially Falcon Heavy? Like sure if Starship lives up to its goals it will be a greater achievement. But how would an ambitious project that fails its most fundamental task (reaching orbit reliably) be a greater achievement than one that actually does meet its goals and was (and is) still incredibly revoluationary? | | |
| ▲ | sneak 4 days ago | parent [-] | | Because the engineering involved in what has already been achieved with the whole Starship program (the stage0/OLM quick disconnect/chopsticks, as well as the full flow
staged combustion Raptor: v1, and v2, and especially v3) is a far greater technological achievement than any part of the F9/FH stack. Starship is a HARD project, and even the components that they have completed are insane levels of engineering, far beyond even the whole F9 program. It’s not just a “does the rocket work” thing. Every working part of Starship so far has been a monumental breakthrough of unprecedented scale. The fact that they built the largest ever orbital launch system (it’s currently not yet reusable but it can indeed put a ~hundred tons into orbit in a single 15 minutes) is enough to classify it as an unqualified success. Their stated goal just happens to be significantly greater than even that. It has already surpassed the (non-reusable) Saturn V in price/perf as well as payload capacity (and development program total cost). |

It’s exceptional that people centrally organized a huge amount of effort and resources towards something imagined by countless humans since prehistory, was far from being a sure thing, had no possibility of revenue and only indirect value, planned and executed a full decade toward a single objective, and succeeded in a single moment shared by almost everyone with a television. Arpanet, the transcontinental railroad, the pyramids…amazing still but lacked the 0 to 1 all at once factor. Starship is inspiring and also not a moonshot. | | |
| ▲ | itishappy 4 days ago | parent [-] | | Hmm... Hadn't considered that. I suppose I was thinking of things in a "for it's time" lens. In general I suppose Starship is quite superior to the Apollo program. Apollo certainly feels more impressive to me, but I completely see how Starship is a greater achievement. |

| ▲ | panick21_ a day ago | parent [-] | | If you go buy actual objective measure of what people tried to achieve, Shuttle is a failure. They literally drop an architecture, Apollo, that was perfectly achieving what needed to be achieved, namely, facilitate humans to LEO, extreme large payload to LEO and large payload to LEO, very fast payloads for outside of LEO and single shot space stations. All of that existed and was able to be build of the shelf. Shuttle then took all that money, in turn losing the US the capability to do all this amazing stuff. With the promise that it could then do all those things again but actually do it cheaper. In that aspect, Shuttle completely failed. Not only did the US lose most of its capability for the next 40 years, some we still have not gotten back. And it did that while costing absurd amounts to develop and then a huge amount to operate, so much that NASA barely had a budget to actually do anything useful with Shuttle. And of course it also took so much time to develop that a whole space station had to be scarified for it. So really the whole Shuttle program is an anti-achievement, it literally directly reduced the technical capability of a nation and turned it from the best space nation in the world into the second best to arguable being second best. Technical complexity by itself is not a mark of great engineering, and that's all Shuttle was. In terms of actual objective measure, Shuttle is a failure pretty much every way you look at it. Failure on cost, failure on safety, failure on ecosystem, failure of evolution, failure operational reliability and so on. Soviets could launch payload and human cheaper to LEO for the next 40 years and only SpaceX brought this back to the US. |

| ▲ | panick21_ a day ago | parent [-] | | That's kind of ridiculous and pedantic. In a solid fuel rocket, the solid fuel is most of the complexity and most of the cost. The rocket flys because of how the solid fuel is shaped and engineered. Reflying the booster cases doesn't change the fact that an essentially new solid booster has to be manufactured. In fact it didn't even financially make sense to reuse the boosters, so it was actually worse then not being reusable at all. As with everything with Shuttle, it all sounds cool when you imagine it, but then if you look at the actual program its basically a 40 shit-show that started very badly and basically never got better. In actual fact, it failed completely as an industrial program for the US. |

Because we haven’t seen a single re-use of a starship yet nor any significant payload brought to orbit, or the orbital refueling turn around and launch cadence necessary to even achieve 1/10th of what Musk suggests is “possible on paper”. Super-heavy is being wasted on a potential dead end 2nd stage in my opinion. | | |
| ▲ | itishappy 4 days ago | parent | next [-] | | Only because they haven't honestly tried (for reuse). We've seen Superheavy caught successfully with engines that could probably be reused, and we've seen Starships lightly splashdown with engines that could potentially be reused if they weren't filled with saltwater. I'd agree that they're way behind schedule and that recent launches have been disappointing but they've demonstrated their components. I believe reliability will come in time, the question is how much time. | |
| ▲ | laughing_man 4 days ago | parent | prev [-] | | By "numbers" I mean the rocket equation. There should be plenty of fuel to put Starship in orbit with a nontrivial payload and have it land again. Yes, the entire system doesn't work yet, but we're already into the refinement stage. |

| ▲ | jiggawatts 4 days ago | parent | prev | next [-] | | True, but they're doing it on a far lower budget than the Space Shuttle. A single RS-9 engine -- one of five used in the SLS -- costs more than an entire Falcon 9 launch with payload, taxes, and profit! Starship is similarly frugal. Its construction is simpler, it is made of cheaper materials, it uses a cheaper fuel, etc, etc... “Any idiot can build a bridge that stands, but it takes an engineer to build a bridge that barely stands.” | | |
| ▲ | poslathian 4 days ago | parent [-] | | I love this quote. mankind having been to space already, the rockets are the sideshow to the way they designed and grew an org that delivered them along with a great business, starting from an amount of capital loads of nobodies have had but failed to do anything interesting with. |

| ▲ | gridspy 4 days ago | parent | prev [-] | | And isn't that decision to leave humans behind on the ground an inspired piece of mission planning. It's wonderful that computers and telemetry has progressed so far. |

| ▲ | sneak 4 days ago | parent | prev [-] | | It was only reusable if you keep building new ones after they explode and kill everyone inside. Did we all forget that the Space Shuttle is a failed program because it was unacceptably deadly due to a high failure rate? | | |
| ▲ | kemotep 4 days ago | parent [-] | | It was only recently surpassed by Falcon 9 as the most reliable rocket program in human history with something like a 98% success rate. All other rocket programs, including Starship are significantly worst in terms of failure rates than Shuttle. | | |
| ▲ | ggreer 4 days ago | parent [-] | | There were 135 space shuttle missions over 30 years, with 2 failures resulting in 14 lives lost, giving a success rate of 98.5%. The second failure happened when the program was mature, which means that either NASA didn't analyze certain failure modes or they didn't take steps to address them. The Space Shuttle's design is inherently less safe than a normal capsule on top. With the orbiter on the side of the stack, any debris from other components is more likely to damage it. The orbiter also had no launch escape system or ability for crew to eject. Also, the solid boosters could not be throttled or shut down early if they malfunctioned. In contrast, capsules like Dragon and Soyuz are above the booster stages, reducing the chance of damage from any malfunctions in the stages, and allowing a launch escape system to get the crew away in the event of an emergency. Falcon 9 has had 531 launches over 15 years (394 of them have happened since January of 2022), with 3 failures (one on the pad before launch, two during launch), for a success rate of 99.4%. Had these failures occurred during manned missions, the Dragon capsule's launch escape system would have likely saved the crew. The mature version of Falcon 9 (block 5) has had 466 successful landings out of 472 attempts, giving it a success rate of 98.7%. This likely means that riding on a Falcon 9 first stage with no additional safety devices (such as a parachute or a launch escape system) is safer than riding in the Shuttle. | | |
| ▲ | kemotep 4 days ago | parent [-] | | Thanks for providing this to other users but my point was about other rocket programs beyond Falcon 9 and Space Shuttle such as Starship. Starship is behind where Falcon 9 was at this point. By the same timelines Apollo was sending people to the moon too. | | |
| ▲ | ggreer 4 days ago | parent [-] | | It's not useful to compare timelines. Of course the Apollo program went fast. Adjusted for inflation, NASA's lunar program cost over $300 billion. It also killed three astronauts. And it didn't have the regulatory hurdles that exist today when trying to launch rockets. Starship's budget is 2-3% of the Apollo program, and its goal is to become profitable long term. I would assume that given a sliver of the same budget, and a much harder problem (fully reusable super heavy lift vehicle), and more regulations than the 1960s, it would take significantly longer. It's also not useful to compare failure rates yet, because Starship is currently a test program. SpaceX believes that it's cheaper to build, test, and revise rather than to try getting it right the first time. They know Starship is not reliable, which is why they don't have real payloads in their test flights. Contrast this to the Space Shuttle, which NASA thought was so safe that they put a schoolteacher on it and broadcast the launch to children across the country. | | |
| ▲ | kemotep 4 days ago | parent [-] | | This is the 4th launch where they are effectively attempting the same thing they were going to do 8 months ago. Musk himself has a deadline of December 2026 for Mars, ignoring Artemis. How many more launches do they need to work out orbital refueling to make that deadline if they don’t test actually sending a real payload into space? |

| Meh, rocket science is just Newtonian physics mostly. SpaceX is just the commercialization of stuff that was invented by our parents and grandparents in the 60s, 70s and 80s. |

| ▲ | idiotsecant 4 days ago | parent [-] | | How to spot someone who has never designed a complex system in their life. | | |
| ▲ | amelius 3 days ago | parent | next [-] | | Be reasonable here. The complexity is within reach of high schoolers: https://youtu.be/SH3lR2GLgT0 | |
| ▲ | nativeit 4 days ago | parent | prev [-] | | Let me know when Starship's complex systems, y'know, work. | | |
| ▲ | panick21_ a day ago | parent [-] | | Funny we were talking about SpaceX and you have to pivot your comment to Starship because otherwise you didn't actually have a comeback. SpaceX has build complex systems, very successfully so. Starship not being finish with development isn't exactly a 'dunk'. |
