SpaceX
There was a company in the US called spin launch that tried to do launch assist. but they only had a technology demonstrator, scaling became too much for VC, the building had to be much much larger and maybe the arm needed to be carbon nanotubes, and the lateral g forces needed really special rockets. But they would have never gotten that money needed unless a super power funded them and SpaceX sucking up all the energy in the room made them pivot to traditional rockets. In short they needed hundreds of billions, and could at best only raise billions.

SpaceX
I know I suck at the new site markup. The problem is not the fuel itself, it is the tyranny that you need to carry the fuel with you, SpaceX could be GIFTED Methalox and it would still be wildly expensive and a dead end. Did you know it would only takes a fuel tank of gasoline to take your body to orbit? Seriously accelerating a 100Kg body to 8000m/s is literally only 3.2 billion joules or 24 gallons of gasoline, and that is ignoring equatorial rotation. The problem is even if you ignore a shell for you, or life support, or oxygen, water blah blah, that fuel itself needs a metal enclosure, and that enclosure needs more fuel, and that fuel needs more fuel, and that new few needs a larger metal enclosure. Next thing you know the actual payload is only < 5% of the mass of the entire rocket. It is not sustainable, that is why space is so wildly expensive, if you can build a launch assist this can actuall scale linearly, even launching at the speed of sound is marginal, the goal is to get good at it so that it can scale linearly with respect to payload, next generation it is 2000km/h, then 20000km/h all the way where your launcher is so advanced it does not even need a second stage at all with it being shot at Mach 30, just ion thrusters for the vacuum stage. All that thrust is no longer needed just specific impulse, by this point you only have like a third stage in size ship. The days of building-sized rockets would be long gone and obsolete. Is the engineering insane? hell yeah! we are only like 1% there, just the transition from a vaccum tube rail to atmo at Mach 30 would cause an explosion of sorts (but way less damage than a blowtorch to the pad), but I trust space agencies to handle vacuum to atmo competently. (most likely gradually adding atmosphere to the end of the tunnel. The most important point is that it is not a technological dead end and the Chinese are seeing it that is why they are starting the baby steps there. And why SpaceX is ultimately a waste of time and money.

You need hundreds of billions of dollars in R&D to really revolutionize space, not even SpaceX can get that much money through VC or private launches. Most tragically the money they have collected have all gone into a moneypit dead end, a traditional rocket. At the end of the day you need assisted launch, period.

@Dahobbs Fine lets bring the discussion here What the chinese are doing is maglev not rail guns, the rail guns destroy the gun after a few launches while maglevs make 0 physical contact Using Gen 1 magnetic assisted launches not only are you accelerating the rocket over the speed of sound you are also starting ignition AWAY from the launchpad aka not destroying it every time you launch. The best part is that you can increment the distance and add more initial velocity, you could literally have a Gen 5 rail (getting to this point is just extending backwards) a fire a non fueled payload at Mach 30 over the coastline, that could probably be enough to get it to orbit even with the angled launch, why? because all of the energy apparatus stays on land it does not need to be carried by the rocket. Will it be insanely expensive? sure maybe 100s of billions and VC won't touch it because they want faster returns on investment, but that is the only NON dead end I see.

Of course venture capital is not cool with throwing away money, that is why it is a failure in the long run. Musk promised dreams of ultra cheap launches so much so that they conned space dreamers (like me, but I never fell for it), had he promised REAILITY aka just marginally cheaper launches than what the Soviets were doing in the 80s his cult would not be where it is today. China is building maglev launch systems, venture capital failed Spin Launch which has pivoted to rockets, to get the morsels to survive https://www.scmp.com/news/china/science/article/3303761/china-bid-challenge-giant-spacex-deploying-maglev-rocket-launch-pad-2028 Yeah if the species goes multiplanetary it will be Musk preventing it from happening more than thanks to him. Launch assisted should have been the only priority even before the Apollo project which in itself was a dead end. I already explained above.

Any rocket system is incredibly STUPID and should ONLY be used to build systems that do not rely on carrying fuel that you need to burn so that you carry more fuel that you need to burn. There is like literally like a few people capable of understanding this dilemma and venture capital sure as hell is not strategic enough for it, let alone orange morons and ketamine addicted con men.

It has taken over because it is backed by large amounts of venture capital, once it dries up and assuming the market remains open tender they will go back in line, and yes that includes starship's incremental nonsense, so much so for "revolution" Had you bothered to read my link That is it that is why spaceX managed to disloge Russia, it finally started being as cheap as the rockets the Soviets were launching in the 80s under communism and Russia in the 90s, that is it.

Going back to SpaceX as a company and the cancelling of the contracts, often overlooked is the economic ideology of fascism: corporatism, officially third way economics (but everyone and their grandma invented a third way economics at least once), the idea was that the commies did nationalizations and the capitalists did the invisible hand. Fascists were "smarter" though, they would command industry without taking it over like the commies, but would let the ideologically aligned oligarch profit and control the government. This is why Russia is currently fascist rich people making lots of money but they had to kiss the ring of dear leader, otherwise they are not only stripped of government contracts but the oligarchs are imprisoned, shot, etc. Guess Donny's prefered economic model?

Of course they can, its just shitty calculations nobody bothered to because nobody cared, and before people still harp but duh that was the frugal genius of Musk, he is still beholden to the fuel tyranny equation. Which still means extremely expensive launches. Musk is a con man https://faustusnotes.com/2022/11/23/how-much-do-spacex-rocket-launches-really-cost/ Conclusion The final conclusion of all of this is that SpaceX are lying about the price to launch stuff into space on their rockets, and the media are uncritically repeating their fabricated price without checking its validity, comparing it with other prices available on the SpaceX website, comparing it with the prices that would be implied by SpaceX’s government contracts, or looking at the evidence from actual SpaceX flight data. The true price of launching stuff into space on a SpaceX rocket is likely more like $6,000/kg, more than twice the number they are citing. It is also clear that reusability has not driven down the price of launches. Reusability incurs a payload penalty, since the rocket needs to be stronger and some fuel needs to be reserved for re-entry. Reusability is also not a radical new idea: the space shuttle’s booster rockets were reusable, and SpaceX’s sole advance on this 1980s technology has been to land them on a barge rather than beside one. This likely speeds up the time to return them to use, and slightly reduces the penalty incurred for robustness (since the rockets don’t need to resist the crash into the water) but it also significantly increases the amount of reserve fuel needed for re-entry. In fact United Launch Alliance (ULA), a SpaceX competitor, analysed reusability and found that it does not necessarily deliver much cost benefit for these reasons. There are formulae for the calculation of how many re-uses are needed for a recyclable rocket to be cheaper than an expendable one, available at the documents linked in this discussion board, and they suggest that in general it only reduces costs in the long-run by about 5%. So no, SpaceX has not revolutionized anything in this regard either. So in conclusion, SpaceX is not revolutionizing space travel, it has not driven prices down at all relative to the long-term trend, launches with SpaceX cost considerably more than their PR suggests, and SpaceX is essentially a low-quality internet service provider with a side-hustle in military contracting, being heavily propped up by murky venture capital. Elon Musk is not, and never will be, anything except a scammer, and in future decades people will look back on how he was viewed in this period with confusion, scorn and disbelief.

Again I have observed literally every form of trolling, as a rule of thumb I never put more effort than the troll. Once sentence answer deserve a sentence response or two at most.

Any failure of NASA can all be laid bare at the feet of anti science republicans that want to cut all funding, the same is true in the sciences, basically all big research positions are more politicians than scientists (something a lot of critics like Sabine Hofstater constantly harp about) because funding is evaporating, and well they have to be begging 24/7 for money. The party that sabotages government and science then has a field day celebrating its failures and propping up shitty startups. That is why the empire is circling down the drain faster than the western roman empire, an eastern roman empire was the best case scenario but no we are speedrunning collapse. The chinese, and western europeans are poaching all of the best scientists now

NASA did everything better than SpaceX, like literally everything. I know you want to count numbers from 11 to infinity but this is just low effort trolling.

Germany survived, but it required 6 million nazis dying in the war and the largest imposed reeducation campaign in history, this campaign was sustained for decades (and ironically what peeved ELMO so much about them) The price of freedom is eternal vigilance.

100% correct, but 7/10 is the lowest polling I have ever seen for the cheeto among republicans, 9/10 normal 8/10 the floor, 7/10 unheard of kinda like a preprogramed robot twitching, and you are worried it is going rogue. That is it though the absolute greatest broadside ever given to Chump and it only changed 1 automaton out of 9. Politics insulation plays a part of course, but this is already baked into the model, fundamentally changing this is the only way the country survives.

There was a shot however small, but that implied Elmo building a Cleetus "information" network, have drones follow him around blasting news on how Trump is going to make his pig farm die a tarif's death and kill his medicaid. I am sorry but shielding Cleetus from politics is how it got this bad to begin with, he will only vote for those that entertain him. Fuck the "No Cloak Room" culture fuck those people that want to "get away", the orange troll makes politics radioactive and these fools blame us for reminding them of it. Everything is lost.

Like it matters, frankly Musk is losing this civil war based on who has sided with whom, the biggest power Trump has is that Cleetus likes him and wants to have a beer with him (and secretly suck his mushroom) and they tune out politics for 4 years, nobody has the same feelings for the autistic manchild. They like him sure, but they don't tune out the 4 years, his wall is made of sand while Trump's is made of tefflon.

Idiocracy is actually an inspirational movie today, I know it has been told a million times but President Camacho was smarter than this, like seriously he put smarter people in charge. I would have taken the corpse of Joe Biden over Donald Trump just because of the people they have on staff, forget the fact that the corpse might be smarter too.
