Will anybody catch up to SpaceX? As an outsider it seems they are impossibly far ahead of the competition.

Blue Origin still has only achieved sub-orbital flight, a far cry away from reusable super heavy orbital flight. Meanwhile SpaceX is launching satellite constellations and Starship is looking increasingly real.

What is the path to victory for other space companies?



Something we lose track of in the software world is that information isn't the alpha and omega in the real world. Everybody from Boeing to China would love to clone what SpaceX is doing, and China is actively trying to do so. And there are no real huge hardware secrets, yet somehow, even with effectively endless resources, these countries/competitors are not only failing to clone SpaceX tech - but aren't even remotely close to parity.

Blue Origin, for instance, not only has Bezos Bucks behind it (while SpaceX was started when Musk was 'only' had millions), but it was also started before SpaceX! And of course Boeing has been around since the dawn of spaceflight. And on a smaller scale lots of brilliant people, including John Carmack, have tried their hand at aerospace, and failed. No idea what SpaceX is doing so well, but whatever it is - it seems extremely difficult to replicate.


The problem for China is that they already had a large state agency doing this stuff. And they did it in a Soviet inspired way. They invest lots of money but their budget is tied up in many long term programs.

They can't just say 'well lets start from zero and copy SpaceX'. They have space station program that needs to continue and they can't wait until they have a next generation reusable rocket. Just like NASA they also do other things, like moon landers and so on.

And despite what people think, China can't infinitely invest in everything and don't. I'm sure the battles for money within China budgeting process are not that different from US congress.

Looking at ESA, getting budget for a new rocket is incredibly hard and ESA member states are richer then China.

Also I think its wrong to say there is no hardware secrets. Developing a very advanced rocket engine is really fucking hard, and to build one and be able to 'mass' produce it like SpaceX does is incredibly hard. Getting there took SpaceX a decade, and government run engine programs are nowhere near as fast usually.

The exact details of the heat shield and reentery of something like Starship also isn't exactly easy to replicate. Doable, but would still require quite a bit of reverse engineering.

SpaceX Starship production line isn't about 'one big secret' but about iteratively improving each part to make it cheaper and better over time. And you can''t replicate that without doing the same.


Supporting old architecture takes A LOT of engineering effort for complex physical devices, creating new architectures from scratch with the learnings from the old architectures often costs too much (and you still need to support the old systems for a long time anyway).

I worked in a project where an architecture was very flawed initially and took almost a decade to move away from it.

So often management pushes for incremental updates on an outdated architecture because the risks are too high since the new architecture might have all new problems of its own.


SpaceX also benefits from vertical integration. They discovered huge costs from trying to use aerospace subcontractors (and had one launch failure because of a subcontractor.)

Both traditional US aerospace and European launch curry political favor by spreading work around to subcontractors. This can't help but slow things way down and make it more expensive.


Aerospace companies have been trying to clone the Lockheed Skunkworks for generations now, with no success whatsoever. The trouble they have is they decide to clone it, and cannot resist "fixing" it in the process. The fixes destroy it. They simply don't have the guts to do what Kelly Johnson did.


Sounds like trying to replace C and C++ ;D


I didn't have $100m to spend on it, either.


>Blue Origin, for instance, not only has Bezos Bucks behind it (while SpaceX was started when Musk was 'only' had millions), but it was also started before SpaceX!

Indeed. SpaceX didn't have infinite amounts of capital during the years it developed Falcon 9 and Dragon. Until Tesla's market cap blew up during the COVID-19 era, Elon Musk had a "mere" few tens of billions of dollars. Boeing/ULA's pockets were and are gigantic, too.

Jeff Bezos has been among the world's wealthiest men for far, far longer than Musk's entry into that group. Let me paraphrase an excellent comment I saw on Reddit, in response to one of the usual lies about how the only reason SpaceX is a decade ahead of the rest of the world is that it got zillions in subsidies from the US government:

>If large amounts of funding is the only thing required to succeed, Blue Origin would now have a nuclear-powered spacecraft orbiting Pluto.


SpaceX did not get subsidies from the government. What they got was a contract to deliver a rocket for a price. They delivered, and got the money.

Paying for a product is not a subsidy any more than you buying a Ford car is giving Ford a subsidy.


>SpaceX did not get subsidies from the government.

I do not disagree.


However, you are still wrong.


Could you clarify, then?


Carmack made reusable, vertically landing rockets before SpaceX did, albeit on a much smaller scale.

I’d say that it wasn’t a failure at all, and more impressive than just about anyone else’s side project I can think of offhand.


>Carmack made reusable, vertically landing rockets before SpaceX did, albeit on a much smaller scale.

No, he didn't, or perhaps more generously "much smaller scale" is doing a LOT of work in your sentence. The core challenge of real rockets is all about scale/speed, and in particular getting to orbit which is where the vast majority of the value starts. The Rocket Equation and material science makes that a completely different scale of challenge to do at all, let alone with a sufficiently useful mass fraction, let alone with reuse, vs anything suborbital. Neither Armadillo nor the DC-X were going to orbit. Hobbies are neat but going from that to something real represents a huge huge amount of work and skill.


> No, he didn't

His co-founder at Oculus, Palmer Luckey, talked about how he did on the Arthi and Sriram podcast (both hosts with considerable big tech experience and VCs at A16Z). He said the company was

> "very successful, probably the most successful (rocket) company in its time in it's budget range. They were doing better things than companies spending 100x more money. They moved very fast, building a vertical take-off and landing rocket, actually long before SpaceX did."

https://www.youtube.com/watch?v=dMhVrYhQUsk&t=1100s


They also went out of business, which seems like a reasonable characterization of something that failed. https://en.wikipedia.org/wiki/Armadillo_Aerospace


If profit is your sole motivator and guide then you may not be fit for a discussion about rockets.


The profit motive has proved, over and over, to be a more effective motivator than anything else, including getting whipped and/or shot for failure.

I remember an earthquake in LA caused a freeway interchange to collapse. The government offered an incentive of something like a million bucks for every day the rebuild was completed ahead of schedule. The contractor got it done in a stupendously short time.


Yes: https://www.nytimes.com/2007/06/02/us/02ramp.html

Which is still something that CA sometimes does, with apparently good results: https://www.ktvu.com/news/california-contractor-earns-8m-bon...


>The profit motive has proved, over and over, to be a more effective motivator than anything else.

The USSR and it's space program would argue differently.


How so? NASA wasn't motivated by the profit motive in the 1960s, either. And SpaceX has completely trounced NASA and the Russians in rocket technology.


If you can't even break even then your entire venture stops. Stopping development and launches is by definition failure. This seems pretty obvious.

I am also not launching rockets. It seems like I am launching exactly as many rockets as Carmack, thus by simple math I am just as successful/good at launching rockets at Carmack.


DC-X predates Carmack and SpaceX both. The actual challenge is to produce an economically viable product that can survive beyond grants and investors. This is important, as it determines whether the system continues to operate or not. Falcon 9, and not the DC-X, flies today.


I think doing it with booster capable of actually putting things into orbit must be a challenging aspect of the problem too. DC-X and Carmack weren't doing this part.


It is what is driving spacex. They also embrace failure. It is where they learn what went wrong and fix it. At one point they were 4 rockets away from going out of business. I think they got down to the last 1 or 2 and they worked and spacex got to stay around and do cool stuff. Without money that company would not exist. They are now forcing the whole industry to re-think what it means to fire a rocket off. They have shifted everyone into thinking reuse is the best way forward. Where as before everything was mostly a one off special one time build. That profit is what is making them sustainable instead of the whims of some senator from whatever state decides to spike your program in favor of his buddies program.


People don't understand how much money Bezos is spending. He is dropping billions every year into Blue Origin.


At some point in the past, I'm sure the same question was asked of IBM, Boeing, or several other large companies. At some point, the big company gets complacent or it gets so large it is bogged down in bureaucratic red tape or any other negative thing attributed to bigCorp loss of leadership in markets from the past. Then, as this sector likes to say "it's ripe for disruption." Sometimes, it takes decades though, and many competitors fall by the way side. At some point, Bezos might bore of his glorified Estes rocket hobby and decide to do something else with his money.


> At some point, the big company gets complacent or it gets so large it is bogged down in bureaucratic red tape or any other negative thing attributed to bigCorp loss of leadership in markets from the past. Then, as this sector likes to say "it's ripe for disruption."

I think it's inevitable that that's SpaceX's fate in the fullness of time.

But it seems like it'll be a while for them. They aren't indulging in typical market-leader behavior. They have kept their prices low - the market leader there by a substantial margin (based on $/kg to LEO). And they clearly have no problem making their best product obsolete via internal innovation. From what I recall, those are the 2 big pitfalls that entrenched market leaders tend to indulge in.


I think the Mars goal helps them a lot with obsoleting their best product. It was obsolete from the start - they knew this one never goes to Mars, it's just a test bed for technologies and a money maker that helps them on the way. While other companies developed their best rocket and then tried to keep it running as long as possible to recoup the investment and make as much money from it as possible, Musk was talking about the next rocket before first Falcon 9 landing.


I’m less worried about that with SpaceX than I am about most companies, because Elon has shown a willingness to just fire a large percentage of a company’s employees with the massive Twitter layoffs.


On the other hand, Elon just fired Tesla’s entire Supercharger team for what appear to be stupid reasons (and is now trying to rebuild from that error.) The unique expertise at SpaceX will be much harder to rebuild if Musk makes a similar mistake in that company. If anything, a massive outpouring of talent is the most likely vector by which the competition quickly catches up and overtakes SpaceX.


> If anything, a massive outpouring of talent is the most likely vector by which the competition quickly catches up and overtakes SpaceX.

I'm skeptical.

Like Amazon, SpaceX is a fountain of ex-employees who have tired of the required workload. I don't see a few extra on top of the current constant exodus changing much.


The talent and even many of the ideas came from NASA and old space, while SpaceX has both inspired and created a generation of it, there was always strong engineering talent in rocket science.

The primary issue for other companies is culture and institutional ability to foster innovation and take risk.

The old space organizations like ULA or Boeing et al and government funded are extremely risk averse and are also optimized for other priorities like having presence in as many states as possible or using old designs/ components to keep jobs funded and so on which limits them.

The new space companies do not have the resources to be as aggressive or fast although they are trying, they do not have free cash flow of SpaceX or extremely wealth and committed sponsor. Blue Origin+Amazon(Kuiper is theirs not BO) have resources but are not fast or aggressive and most likely chance to compete if they can get their culture sorted.

Private rocket companies were not successful businesses before SpaceX for a reason, its success has inspired capital inflows but problems are the same.

---

Astra, Rocket Labs, Relativity and Firefly are the only ones with some track record of orbital launching vehicles, Astra went private at 99% down round for just 11M in March-24 and are probably going to be either acquired or shutdown.

Firefly has no immediate reuse plans. Terran R and Neutron are the realistic contenders for reusable vehicles if successful(big IF) then will have Falcon 9 equivalent competitor commercially available by end of the decade (13 years after Falcon 9 landed regularly in 2017). Starship will be active well before 2030 and be a generation ahead again. SpaceX when Starship launches commercially say in 2025 are at least 20 years ahead of everyone else and currently 10 years ahead with Falcon 9.

The last time space industry had this kind of disparity were the few years after Sputnik and other soviet first launches, to catch up the federal government spent multiple % of GDP and made it the national priority and employed 400,000 people to do it. SpaceX is not Soviet Russia it is a domestic company NASA and Space Force benefits from and Trump/Biden are not Kennedy so that is not going to repeat.

Realistically next 40-50 years will be dominated by SpaceX in both satellites and rocket vehicles, even if they stop innovating soon.


There seem to be a lot of things that cannot be explained if we take what you're saying as an assumption. For instance from 2011-2020 (when SpaceX started launching to the ISS) NASA had no way to get crew to the ISS, and relied exclusively on Russia. That can't be dismissed as just risk aversion. Similarly Blue Origin is filled with old space talent, was founded before SpaceX, is funded by Bezos Bucks, and yet can't even manage to achieve an orbital flight. Also SpaceX's early talent included people like Tom Mueller [1] who would go on to work as CTO. Notably he was picked up on SpaceX because of the rocket engines that he was literally building in his garage!

I have no claim to knowing what SpaceX's secret sauce is, because the problem I think you run into immediately is that any sort of logical explanation then bumps into issues like the ones I'm mentioning here.

[1] - https://en.wikipedia.org/wiki/Tom_Mueller


To be fair, Tom Mueller was also head of liquid engine propulsion at TRW as noted in the wikipedia link, he wasn't exactly an amateur. I had the same initial response to the gp, but I think they got it right: "The primary issue for other companies is culture and institutional ability to foster innovation and take risk." I think SpaceX went after people who knew what they were doing, but were frustrated by the bureaucracy. I get the sense that Blue Origin hired people with experience who were pretty happy with the way traditional aerospace worked, and kept doing exactly the same thing at Blue Origin.


> I think SpaceX went after people who knew what they were doing, but were frustrated by the bureaucracy.

Legend had it Musk hired Mueller after meeting him and seeing a liquid biprop engine he was building in his garage. That sounds exactly like the type of person you describe. “I can’t do the cool shit I want to do at work because of forms/approvals so I’ll just do it myself at home”.


(I know it’s unpopular these days but) this is where I think Elon has to be given some credit.

He set an implausible but interesting ’mission’ from early on. He set the culture of the company from the start such that the concept (borrowed from the tech world) of failing and iterating fast actually happened (rather than just being talked about in corporate presentations). He brought naive but effective ‘first principles’ thinking to many of the questions or problems which probably helped avoid the conservatism of ‘old space’. He brought enough money to start, but it was little enough that they had to be scrappy and lean for survival, which probably fed into the culture and built a great team further. And (by luck or judgment) he hired the right people, like Tom Mueller, who was already a rocket engineer, but was frustrated by his previous industry experience.

(And of course, back then he didn’t have the baggage he has now, which made these things easier to achieve.)


> NASA had no way to get crew to the ISS, and relied exclusively on Russia.

The reason NASA was doing that was because of risk aversion and lack of innovation!

The shuttle was shut down because NASA couldn’t afford another disaster like Columbia and there had been absolutely no meaningful progress to replace it .

Without spacex, that would still be the case , Dreamliner is still not done a demo flight and Boeing would have held NASA by the balls and renegotiated from fixed price to cost plus contract as they have been doing for decades.

SpaceX forced the hand by delivering on commercial crew (CCS)

The shuttle had bunch of older parts designed for other programs and was 30 years old in 2010.

SLS flies on engines that are decades old from shuttle era with no plan for new engines and still costs in multiple billions per launch !

If not for spaceX we would be cheering BO for successfully delivering the Vulcan engines and being proud of that as pinnacle of private space .

BO official Moro is step by step ferociously. They were always culturally tuned to be risk averse and careful


The only person more important than Tom Mueller for SpaceX is

Mike Griffin https://en.wikipedia.org/wiki/Michael_D._Griffin


Mike Griffin has almost no relation to SpaceX. He's a footnote at best.


And Gwynne Shotwell, COO of SpaceX.


Astra is not private yet. The SEC is still reviewing the take-private offer that Astra's board accepted from the group of investors. The take-private move is essentially an acquisition.


Waiting for a rot in competition rather than upping one's own game seems a bad strategy. Sure, Spacex will seize to exist at some time. But so will everything else.


s/seize/cease


Disruption can come from any direction. I don’t think Spin launch has better than 5% odds of success, but it could drastically undercut SpaceX in terms of $/kg to orbit and there’s a few others willing to face SpaceX head on. Or China, US military, etc may decide to heavily subsidize a competitor for strategic reasons outside of economics.

Starlink is becoming a core component of their business model which presents its own issues. The service is attractive today, but cellular or wired connections have inherent advantages in most situations and could seriously eat into their customer base fairly quickly. T-Mobile/Verizon/etc 5G wireless home internet for example is generally a better choice for most people.

Which isn’t to say SpaceX is in any kind of imminent danger, rather the company has significant long term risks.


It’s possible, but the whole reason Starlink has a userbase is because there’s large areas where traditional telecom companies either never had enough interest to set up infrastructure or let what had already been set up rot. If that were to change meaningfully it’d require a significant shift in strategy from Verizon, AT&T, etc.


I think this is a very US centric viewpoint (and I'm actually not convinced that it is correct in the US - see https://undergroundinfrastructure.com/news/2023/december/fib...).

Outside the US there is major major FTTH rollout going on everywhere. UK will get to ~90%+ penetration within a few years (it's at 66% now, 83% if you include HFC DOCSIS3.1 and growing at ~1% a month, including some very very rural areas).

All of Europe is basically like this, and will have/already has overwhelming FTTH coverage. The same is happening in Asia and even in the more developed parts of Africa.

So every month the addressable market for Starlink IMO declines. There will of course be places that are extremely rural that won't get FTTH for a long time (but I think they will eventually), and underdeveloped countries will struggle to roll it out for a long time too - but there is a lack of capacity in these underdeveloped places to pay for starlink.

What Starlink as actually amazing at is bringing the price of fixed line connections down. A lot of countries have ridiculously high fixed line/mobile data costs (I would assume some level of corruption is happening to keep competition out). Starlink will push those prices down and force providers to offer unlimited data packages in those areas. However, I'm not convinced Starlink will see the benefit of a lot of that.

Don't get me wrong - Starlink is an awesome service that really benefits humanity. However, I think the long term economics for it are poor for it to grow substantially more (this may be ok as I believe it is EBITDA positive now). And I think churn will be a problem in developed countries as more and more of them get FTTH.


How could it be a US centric view when the US has faster bandwidth than almost every country in the world? It's ranked 5-6th in the world for average bandwidth and 10 in median.

https://www.speedtest.net/global-index#fixed


I literally said that it wasn't true. There is a common misconception that the US is miles behind other countries in terms of FTTH coverage and/or rollout has stalled.


Oh I totally misread you ! Sorry


I think T-Mobile trying to buy US cellular suggests they are approaching 5G home internet as a real growth opportunity. The infrastructure rollouts are just far more reasonable tha trying to run wires everywhere.


Yeah land based networking just makes less and less sense when you look at it from first principles, wireless is fast enough for most connections it has enough bandwidth if distributed and being in orbit makes widely distributed networks trivial compared to doing it on earth.

I dont know if it will be starlink but I do expect(hope) ground based telecom to go the way of floppy disks in the coming decades


Unless you on a boat being in land is a huge advantage. 5G only needs ~10,000 towers to cover most people on the US. From there you scale density based on where people actually live.

Satellites however move so you need to accept the network sucks in moderate density areas or you have vastly more coverage in low density areas than you need.

Wired connections inherently provide a lot more bandwidth, and in dense urban environments the last mile isn’t a mile it’s within a building.


Can you site that number? It really doesn't pass the sniff test for me, unless the word "most" is doing some pretty heavy lifting.

A quick search suggests that the range of a 5G tower, operating only at low/mid-band spectrum (so in other words, below peak speed - but at higher range) can only operate in the 1 to 3 mile range. [1] We'll say 2. That's an area of pi*2^2 = ~12.5 square miles, we'll say 13. The area of the US is 3.8 million square miles. So your number would provide coverage for (10,000 * 13) / 3.8 million = 3.4% of the US. That maybe enough to cover the most exceptionally dense urban locations, but you're missing a lot of people there.

And, again, this is just for the low/mid-band stuff. And then you need to regularly maintain those towers. While you could get global coverage with relatively few satellites that can just be trivially remotely launched/decommissioned. A quick search there [2] turns up a current practical (not peak/theoretic) bandwidth for Starlink in the 100+ Mbps range + ~50ms latency. I have difficulty seeing a logical argument for ground based telecom, beside as a hedge against WW3 when probably the first thing that will happen is a huge chunk of all satellites going poof.

[2] - https://www.pcmag.com/news/starlink-speed-tests-2023-vs-2022


Your first link says “On average, the maximum usable range of a cell tower is 25 miles.” Which is relevant because we aren’t trying to provide service just for high density areas.

Before you ask if 10,000 * 2,000 = 20 million square miles is high, handoffs require you to be in range of multiple towers so there’s a lot of overlap and hills, ocean, etc that reduce useful range.

Ultimately there’s 142,100 cell towers in the US, but that’s including density from urban areas and redundancy from multiple cell networks. Anyway, the point I was making was that Starlink is targeting low density areas by necessity they simply can’t target NYC density for any reasonable constellation size. However, if you’re a cellphone company and you’re already covering anywhere in the US with 50+people per square mile extending that to anywhere with 5+ or even 0.5+ people per square mile and killing Starlink just doesn’t take that may towers.

https://www.benton.org/headlines/us-cell-towers-and-small-ce...*


"Usable" is going to mean at the max possible wavelength. The problem with telecoms is that there's a physics imposed inverse relationship between frequency (speed) and wavelength (penetration/distance). So it's not like computing where we basically have gotten a free lunch with stuff that goes faster, runs cooler, and takes up less space.

Each upgrade with telecoms entails a sacrifice. You can have really fast signals that can't go far and have difficulty penetrating obstacles like walls/buildings/hills/etc, or you can have really far reaching and high penetrating signals that can't go fast. So for instance Verizon's max speed towers can only reach 1500 feet [1], so I think my estimate of ~2 miles was a pretty reasonable meet in the middle.

All that said I agree with you in principle. Obviously space based telecoms are much better for less populated areas than heavily populated, but I'd argue that that space based can scale much more easily. The ground based telecoms aren't just those 140k towers, but also the other 450k nodes on top. And that's to cover a pretty small geographic area. And each of those nodes not only needs land and construction permits, but they also need to be be regularly maintained, and so on. It's a pretty big deal. For space based coverage, you can just launch your satellites from Texas and have them providing coverage on the other side of the world in a matter of minutes.

Put another way - imagine we were creating a civilization from scratch and these technologies were all 'unlocked.' I don't think we'd be using ground based stuff much at all. In the present when the infrastructure already exists, there's no reason not to take advantage of it, but in general it just doesn't scale so well.

Don’t forget those towers covers the vast majority of US population with high speed connectivity, where Starlink only has ~1 million US customers 1/300th the population. Those ratios aren’t that off in terms of customers per unit, but the problem with scaling satellites is they don’t stay in one location.

You can’t just put 50 satellites next to each other over a suburb and call it a day you need a ring(s) of satellites circling the entire globe to reach whatever your target density is along their full orbit. Unfortunately, most land has really low density North Dakota only averages 11 people per square mile, while Florida a mostly empty state sits at 422.

Target 10 people per square mile (adjusting for household size and rates percentage of people signing up) and just about all your satellites are useful across the entire US.

But Pick 100 people per square mile 90% of your time over North Dakota is wasted. Worse large chunks of Florida are also nearly empty as most of its population is along the coastline in places like Sweetwater where 8,800 people per square mile live. So your wasteful 100 people per square mile in ND still only covers a small fraction of the population in Florida.

Cellular is the reverse the first 10k towers are largely “dead weight” that cover few people per tower, but the rest of the 130k are really useful because you optimize locations for density. Swap that to satellites initially the constellation has very high utilization, but the ratio keeps getting worse as you add more satellites.

PS: Starlink could try to vary speeds or prices more based on density, but people really want predictable results for their money.


This is what I was trying to say above but much more detailed an eloquent. Theres a lot dislikes in this thread but not many folks addressing the points.

The thing about high density places with a ton of infrastructure is that wired will always be the best because you have close access to infrastructure and its likely to already be built in. For rural areas or even suburban areas the equation starts to tip to orbital wireless for the reasons you state above and also geographic realities make ground based wireless unreliable in places where there are mountains valleys canyons etc.


We’re talking about 5G vs satellite not wired.

There’s a 4 orders of magnitude difference between high density areas and low density ones. So no you don’t need millimeter wave everywhere. You can increase bandwidth per tower, but you can also the number of cell sites.

Further every frequency you add removes users from other frequencies. IE: At 10 miles you can use a subset of frequencies, but those frequencies don’t need to cover for people 100m from the cell tower because those are on 5G.

Thus double the number of cell sites means there’s an extra circle of people on mm wave frequencies around the new towers. Thus you more than double effective bandwidth in low density areas when you double the number of towers.

Meanwhile the reverse happens with satellites. For a given number of satellites there’s some areas where you have sufficient capacity for the density at those area. Suppose you have enough satellites for ships and aircraft over the ocean, add new satellites to handle higher density and the time those satellites are over the ocean isn’t getting you new customers. IE the percentage of time the average satellite is at 90+% capacity drops when you add more satellites.


I have a lot of difficulty in understanding why you think it's "trivial" to launch a satellite, but not trivial to build a cellphone tower.


Building things deployed to land in real life, basically sucks. Building out a tower requires buying the land (or even possibly getting involved in extremely dirty eminent domain lawsuits), getting countless building permits/inspectors, architecting your building in accordance with local regulations and any sort of geographic peculiarities, organizing a construction team, [finally] building it, and then maintaining the building itself as well as the various regulatory regulatory, tax, and other requirements that come with such. And that's for exactly 1 tower! And you really cannot overstate how big of an ordeal this is. If you think NIMBYism is bad for housing, think about how people feel about building phallicy energy generating towers reaching hundreds of feet in the air around them.

By contrast SpaceX: build satellites, launch satellites, done. They can launch tens (and soon hundreds if not thousands) from their base in Texas with a single launch. There's still some bureaucrazy they have to deal with, but this is overall just a many orders of magnitude greater difference in terms of scalability and overall ease. And when satellites start hitting end-of-life - no problem, just deorbit them and continue expanding the swarm.


I think this is only kind of true. 10000 towers is a lot when you consider that probably half of them are in very low density areas. LEO based satellites are a really good way of covering the desolate areas (oceans, deserts, farm land with very low population density etc), and areas with medium density and lots of elevation changes that would mess with ground based coverage. Starlink was never going to work well for urban (or even sub-urban) areas, but airplanes, boats, and ~20% of the US population is nothing to scoff at.


Cell towers already exist to provide cellular service in low density areas. In general people expect service to be generally available not simply be available in cities and subdivisions.

Some of that is provided for free when covering higher density areas which satellite networks like Starlink simply can’t handle at any kind of reasonable constellation size.


> or you have vastly more coverage in low density areas than you need

That's not really a problem, and is already the case over most of the world (particularly oceans.)


Satellite internet is inherently a niche market. The physics simply don't allow for example good satellite coverage of even 10% of NYC, because you just can't get enough satellites flying over NYC at the same time to handle that much data. And there are limits to how much better you can make the individual satellites themselves, since you have a very limited heat budget in space, where you have to rely 100% on radiative cooling.

So, for any square mile of land, you can have at most some small number of subscribers. Sure, you can cover a huge surface, but only with a very low density. Conversely, the vast majority of the world's population lives in huge clumps in small areas.


Billions of people live in low density areas. Hundreds of millions live in NYC-type very high density areas. Satellite can still serve very high density, just at limited rates. Satellite internet is very far from niche.

Starlink should (annd perhaps anlready do) approach commercial high rises with a single uplink for the building, shared through the building network. Even as a backup data system, still very valuable system.


Satellites really can’t provide coverage at full 1 acre lot suburbs level density let alone NYC level density.

Starlink has ~1 million customers in the US from ~6,000 satellites so you’d think they could do 10x that with 10x the number of satellites. But much of the US is low enough density that their current constellation is already sufficient and effective bandwidth per satellite is maximum bandwidth * percentage of orbit in useful locations. Which means 10x satellites are closer to 3x useful bandwidth and it gets much worse the higher density you’re aiming for.

Ahh you might think just offer lower bandwidth per customer in urban areas, but people will pay less as the bandwidth drops and Starlink is already fairly slow.


I don't think satellite is cost effective for high density areas. If you have enough subscribers in a given geographic location, it makes more sense to put up some cellular towers, which can be maintained by people on the ground.


Spinlaunch makes no sense on earth, they should put a tether based spinlauncher on the moon instead.


> T-Mobile 5G wireless home internet for example is generally a better choice for most people.

I was speaking with someone from US Cellular at a conference recently and they were saying their whole advantage over T-Mobile was spectrum in rural areas. Which explains why they were bought out by T-Mobile.

T-Mobile is also in the process of rolling out fiber home internet to compete with AT&T because 5G isn't that great.

T-Mobile's network might be good enough in suburban areas but it's lacking in rural areas. This is where Starlink is competitive, and also places like the middle of the ocean.


There’s absolutely markets like sailboats or back country RV’s where starlink has inherent advantages. Obviously 5G isn’t rolling out everywhere.

The issue is it’s rolling out enough places to start hurting Starlink because speeds are generally higher and it costs 50$ vs 120$ / month.


Not sure that's true. Around here (rural Montana) the 5G providers will sell "home" service in town, but not outside town. My assumption is this is because they have enough capacity on 2GHz in town with small cells but not enough on the large 700MHz cells in the country. Starlink is really the only proper provider in our neighborhood. You can use LTE Hotspot but the carrier will throttle traffic pretty quickly.


I worked on a deal with a US state government to bring broadband to unserved and underserved areas by working with local ISPs. Largest proposal of my career so far and will be nice come bonus time if we win but, honestly, if it were me I’d just give the unserved folks out in the country starlink vouchers instead of pouring millions amd millions into ISPs and call it a day.

I probably would have been fired if I said that out loud in front of the client.


Stoke Space is developing a novel fully reusable rocket that could be competitive with SpaceX.


If we are betting on a company that hasn't launch anything and wont for years to come. We know we are grasping at straws. They haven't even tested reentery or landing of a first stage rocket yet. They have a cool design.

They are just one of many hopefuls in the industry.


> They are just one of many hopefuls in the industry.

There's a big difference. Virtually all rocket startups are doomed regardless of whether their rockets succeed or fail because of the competition from fully reusable Starship and/or Terran R and/or Stoke.

Relativity and Stoke actually have a chance of success. It's small, but non-zero.


Spin launch doesn't even have 0.005% odds of success. 5% is an absurd number frankly.

The $/kg doesn't matter that much in practice in the real world. Maybe in the future where people are launching only fuel. But not now.

The reality is Spin launch requires people to build sats 'for' launching on Spin launch. And that's simply not happening. No major consumer is gone do that.

Spin launch is borderline a grift.


Square cube law means smaller satellites care less about g-forces. People shot vacuum tubes out of artillery shells as part of proximity fuses and they would survive just fine.

A cellphone experiences higher peak acceleration when hitting a floor when falling off a table but they are generally fine. So yes some sats would need modifications, but not necessarily significant ones and you can trivially test those conditions prior to launch. A Starlink competitor would happily design for such if it reduced their launch costs by 90%.


First of all, all sats need modification. Things like reaction wheels simply wont work the same. Usually launch vehicle selection is done well after engineering on the project is along quite a bit. SpinLaunch basically requires that you make a decision to be SpinLaunch compatible as soon as you start. And that will force you to use some of their parts.

This simply isn't something that anybody would do unless there is a huge benefit to it. Spin Launch still requires a rocket, and one that will likely not be reusable one anytime soon. So the idea that its going to massively reduce cost is a fantasy.

To even have any cost saving at all they need a huge number of launches. There simply isn't a market for that many tiny sats. There is a reason all the constellations have moved to larger sats that are not SpinLaunch compatible. Micro launch is a tiny market and companies like SpinLaunch are just lying to their investors, just like Astra did.

If we are looking at things like consumables, it would take 500 SpinLaunch launches and that doesn't even match a single Starship launch. How anybody could think this would be cheaper is beyond me.


The answer is SpaceX is being held at a low headcount strategically. Turns out, if you‘re an engineering company you don‘t need a lot of top brass, DEI committees, artificial diversity hires, inner-company minority peer groups and bloated HR departments. You instead reduce friction as much as possible.

I hate to say it, but maybe Musk is onto something. SpaceX hires top people who work a lot, efficiently. This seems to work for them. Duh, I guess?


SpaceX is a true marvel.

The closest competitor is Peter Beck's Rocket Lab. That's why SpaceX is using their monopoly position to attack them.[0] As I said in a different post, Beck is a combo of Musk and Tom Mueller.[1] The "only" things that Rocket Lab is missing is first-mover advantage, and billions of investment.

I don't think you can call Rocket Lab a competitor of SpaceX by any metric. Besides, look at the comments in the link you posted, it's pretty obvious that SpaceX isn't attacking them.


At some point SpaceX will reach the limits of how efficient they can get as dictated by physics. Their competitors will get there eventually, maybe decades later. But eventually the market will mature and they will become competitive. Same as any other industries, smart phones, electric cars, etc.


It's not about physical efficiency of the rockets so much as it is about their reuse. When you launch a rocket, fuel costs are basically a rounding error - well under a million dollars in general. Nearly all of your costs come from the rocket itself. And before SpaceX we were simply throwing away these rockets after a single use. Well technically the Space Shuttle was "reusable" but the refurbishment required was so extensive that they may as well have been rebuilding it from scratch after each launch. This is why SpaceX's audacious initial goal of reducing space flight costs by orders of magnitude was completely viable.

I think companies will have difficulty competing against SpaceX, so long as SpaceX is ideologically motivated. Right now their goal isn't to make a ton of money, but to create a stable civilization on Mars. So once we start headed to Mars them making next to no profit on launches, beyond what's needed for development and basic sustainability, would be perfectly fine. So you not only need to hit technological parity, but then somehow also go well beyond them in terms of cost reductions - at least if your motivation is profit.


Not to mention that 2 out of 5 Space Shuttles suffered catastrophic loss, one of them (Columbia) almost certainly because it was being reused and the heat shield failed.


Columbia didn't fail because of heat shield reuse. It failed because a chunk of foam crashed into a important part of the heat shield at high speed and created a big hole.


I’m always deeply skeptical of appeals to the “laws of physics”. Yes, there are some hard constraints there, no, it doesn’t account for bright ideas for how to make those less important; the laws of physics stop us shrinking vacuum tubes small enough to fit billions on a chip, but it turns out that that doesn’t actually matter


There’s no working around the rocket equation unless you invent antigravity, which I personally think is a harder problem than transistors.

The cost to develop in the first place may be too high, except for maybe nation states.

Falcon 9 funded Starship. Now there is little funding for a competitor, ignoring the fact that Starship will sink that even closer to 0 with such low launch costs.


BlueOrigin is not making money but investing more then most nation states. In fact, Bezos is single outspending Europe in terms of rocket investment. Bezos invested way more in New Gleen then Europe in Ariane 6. Not to mention outspending India whole space budget.


This only strengthens my point. Given all that spending, they still are seemingly nowhere close to a Starship competitor.


You believe conventional turbo boosted rockets are the end game of space travel? There is a lot more to come I can tell. at least 200 years of development if not more with current knowledge.


What will ultimately limit SpaceX, and launch in general, is deposition of water (either water in the rocket exhaust, or water from later oxidation of unburned fuel in the rocket exhaust) in the upper atmosphere. The stratosphere and mesosphere are extremely dry, so this limit is lower than you might think.


PRC has several commercial reusables on the way and IIRC 3 seperate mega constellations planned for short/medium term. If there's sustained demand, there's no reason they can't do to space launch what they did to ship building. At 30-40 F9s, IMO people are conflating SpaceX's reusable "capability" lead for actual scale. If other sectors any indication, would not be out of question for PRC to economy of scale 100s of F9 tier launch vehicles and eclipse SpaceX in aggregate payload in a few years of buildup if there's business/strategic case for it.


China is broke, like dead broke. It will follow Soviet Union's footstep of space race with the US in 1960 and collapse of Soviet Union.

Ship building is not the same technology level as spacecraft. China famously exclaimed in 2019 that they will be able to duplicate EUV in a few years, when dutch introduced EUV restrictions in China in 2019. Still nothing from China on EUV. Still nothing from China in terms of plane engines. Their new carrier in 2024 is still just a "demo" carrier, not to be used in real combat.

The comment history for this user is interesting.


Indeed - every comment in a topic directly related to China, and all in some way negative…

Reuters and news about China. quite reliable indeed. In the meantime China is boosting forward. Absolutely no way that there is 46% unemployement in China. In general all over the world there is shortage of workers. Also in China. You mentioned Soviet space race failure. Russia/USSR did not fail with the space race. Even today they have a strong position in space travel.


The only reliable rocket they’ve got is the Soyuz, everything else suffered major failures in the past decade.

Nevertheless they’ve got their asses kicked by Starlink so I’m sure they’re trying to figure out how to make their own.


> PRC has several commercial reusables on the way

They currently rely heavily on small hypergolic rockets. It's really hard to tell just how scared people should be of China's rocket program. On the one hand, they undoubtedly have a lot of very smart people. And they don't seem to fall in love with boondoggles like SLS/Orion. But on the other hand, they seem to be really stuck in the past for a country with so much advanced space tech.


They're moving away from inland hypergolics, to coastal cryogenics, especially for commercial. TLDR history is PRC space program really exploded in last 15 years. Before that, budget/development poverty tier. Most of payload considerations since are urgent military (ISR), so prudent/expedient to use existing hypergolic infra (legacy/synergy of strategic missiles) to maintain launch tempo because they don't want boondoggles when it comes to getting military space infra up reliably. Cryogenic LM6/LM7 first test only in mid 2015s. They'll switch over eventually, but right now priority is still military launch. IIRC all the current reusable efforts are cryogenic fuel.


We are witnessing rail road tycoon, but for the solar system. The foundations set in the next 50-100 years will be the foundation of the human solar empire. Spacex has no competition for the foreseeable future. And anyone who uses them as a service provider will be quickly subsumed if they’re successful, as the present article indicates.


so invest in the first company to launch bars and whorehouses along their orbital construction sites?


Air and water providers first, probably. Your picks are obvious next ones, though.

Slow and steady wins the race. Boeing is only slow by the way.


I don't see anyone catching up to SpaceX anytime soon. There are several possibilities on the horizon to catch up to Falcon 9, if Starship gets delayed for a number of years for example, but that seems unlikely. Competitors can continue to hang on via just the threat of SpaceX taking over the entire launch industry though but they'll basically stay minority players. That is until the cost advantages of SpaceX become too great and companies become large via using SpaceX to push their own business models.


Amazon Kuiper should go into beta later this year: https://www.satelliteinternet.com/providers/project-kuiper/


That's not possible this year

Hopefully there isn't one. We need a Pepsi here, not an Amazon.


I'll take AWS over... ?


There is also Rocket Lab with rocket nerd Peter Beck at the helm.
