On call should go against negotiated hours like 1/3 or 1/4. 3-4 8-hour shifts on call = day off. A single shift requiring active firefighting = day off.

2 years of 60+ hours weeks is not good engineering culture, or any kind of culture.

Particularly when simultaneously "We are currently in YC Startup School as Geddy at geddy.io and we plan to launch soon."

It's a bit astounding to realize Ballmer was good.

HLS isn't going anywhere.

> HLS isn't going anywhere

I've been hearing this about every SpaceX project for the last twenty years.


Judging by the fact it's 2026 you must be writing this from the Mars base.

> Judging by the fact it's 2026 you must be writing this from the Mars base

SpaceX was started in 2001. It announced Falcon 9 and messaged its reusability ambitions in 2005.

Falcon 1 wasn’t going anywhere because making rockets is too hard. Falcons 5 and 9 weren’t going anywhere because medium lift is a different ball game. Falcon Heavy wasn’t going anywhere because timing that many engines impossible. Reuse is impossible. (The kerosene will clog everything.) Then, after refly: the total launch market will never be more than $5bn, so reuse is useless.

More recently stainless steel can’t work. Now it’s shifted to reuse and refurbishment being too difficult, or refueling being impossible because of boil-off. Because keeping shit from boiling, apparently, is just unsolved engineering. ಠ_ಠ

Not everything SpaceX does is genius the first time. But they’re ridiculously good at not persisting with stupid. The idea that a dozen rapid depot launches is somehow a gating concern, again, as a tech demo, we’re building the depot eventually, is just such a weirdly small and big concern.


To paraphrase, spacex is "making the impossible merely late"

> But they’re ridiculously good at not persisting with stupid.

They are persisting with HLS though.


> They are persisting with HLS though

Through what? What experimental data do you think renders this path foolish?

Because I’m seeing a rapid-reuse heavy lift system with a fuel depot being built.


I dunno, the fact that nobody can say how many fuel launches a moonshot is going to take, but at least 12? And that the lunar orbit chosen due to available energy makes rapid extraction impossible?

"How many fuel launches" is the error margin.

If they get less performance or more mission payload, they can add tanker launches. If they get more performance or less mission payload, they can remove tanker launches.

People ran into "the design is 10% heavier than planned for unexpected engineering reasons and now we have to make hard choices" on space missions far less complex than a literal Moon landing. SpaceX has externalized the "hard choices" into the tanker count, pre-emptively.

The lunar orbit of Artemis is defined mainly by SLS/Orion's performance, or lack of thereof. The specific NRHO was a Gateway choice, and might now be dead alongside it, but by itself, Orion can't get to low Lunar orbit. Which drives some peculiar design choices.


So many (perceived) problems with spaceflight and building moon bases and the like are solved by simply making the process and cost of launching faster, easier and cheaper; the problem that NASA has always had is that each launch, even with the reusable space shuttles, cost billions and took years of engineering, planning, etc. To the point where yesterday's launch was done with (what I perceive to be) salvaged parts where the engineering was done decades ago, because engineering something new would be too expensive and take too long.

Sure, don't fix what isn't broken and all - *nix tools are decades old too after all - but still.


> the fact that nobody can say how many fuel launches a moonshot is going to take, but at least 12?

Nobody has ever done in-orbit propellant transfer or storage. We’re building it to see what those numbers shake out to, and how the propellant gets lost. (Boil off? Leaks? Incomplete transfer? Weird, unexpected degradation because space? ¯\_(ツ)_/¯.)

If it works, it dramatically reduces the cost of lunar and deep-space access. You’re saying that isn’t worth it because it isn’t certain? This is spaceflight. Nothing is certain. We have to weigh risks and payoffs. And then mitigate them. The time for mitigating this risk is this (and probably next) year. If the refuelling is dumb, the plan changes—Blue Origin is testing its own approach on the same timeline.

Like, in Apollo 11 we fucked up the lander’s fuel budget. The astronauts were literally running out of fuel because a foreseeable problem, the surface being bumpier than expected, wasn’t contingency planned for over ten preceding missions. And we’re trying to do better than just retreading Apollo, because Apollo—strategically—failed as a platform for further manned spaceflight.

> the lunar orbit chosen due to available energy makes rapid extraction impossible

Isn’t NRHO an Orion limitation? Can Orion circularise on its own?

Also, rapid extraction hasn’t been a requirement for the Moon since ever? If you want rapid extraction, plant a ship that can motor off the Moon home in one shot as an emergency-egress option down the road. In the meantime, you’re days away from help under ideal circumstances; realistically, we don’t have rescue options.

Starship might be crap. But the bets look good, and the project is on the whole no more ambitious than the original Apollo missions. The criticisms you’re raising are either fundamental to the mission architecture because it’s developing a new spacefaring capability (refueling and rapid relaunch) or cost-cutting choices irrelevant to HLS (Orion’s second stages being efficient but underpowered).


Ughhh, Elon Moosk amirite? Such a fraud, because [???]

I don't really understand why these kinds of comments persist except as some pathological cope when confronted with a world that doesn't work the way you want it to.

It's not convincing, it immediately outs you as a zealot, it's counterproductive in every single way. Why keep doing it?


> don't really understand why these kinds of comments persist

One, you can make money criticizing Elon on the internet.

Two, controversy is catnip to the man. DOGE was a disaster. X and xAI look like aborted disasters. And he’s clearly gotten bored with Tesla. It isn’t hard to project that on SpaceX if you don’t know the heritage.


My guess is Tesla's pivoting to batteries and storage. Huge demand, great margins, competitive advantage.

I'm very disappointed Tesla has (seemingly) abandoned its goal of producing 20m Model 2 per year. Forfeiting the mass market is a bummer. More so every passing day.

(I'm bearish on Robotaxi and (Tesla's) self-driving.)


He's a much bigger asshole than he is a fraud, but he is a fraud too. There's no hype like Musk hype.

I fully agree with you, but the answer is obviously "because he's a very unpleasant man."

Lots of powerful people are unpleasant, but Musk additionally got involved in politics in a very visible way at a very partisan, polarising time in American history. He didn't attract as much hate before 2024.

Maybe more people should listen to Musk's political message. The Biden Administration was playing nasty games, blocking progress on both SpaceX and AI generally.

That's beside the point... Fact is, there's a schism and no one crosses it. Elon picked a side I guess, so the other side hates him.

The Biden admin was TRYING to slow down AI. It did not work for them.

As for SpaceX I'm not sure what you mean seeing as how the government is easily its largest customer...


just saying: he is good at vaporware on a large scale and kind of a fucked up person. It's not weird people are skeptical. But he also has basically an endless money supply so he can throw money at problems and make them go away eventually. But his timelines are basically all lies used to get venture and retail money into the game.

That describes basically all founders though, minus the endless money supply. That's how business/sales works: make promises, build product later.

Also SpaceX, Tesla, PayPal, OpenAI, Grok and Neuralink aren't vaporware...

The claim fundamentally doesn't make any sense.


Cybertruck, Semi, Hyperloop, robotaxi, point-to-point rocket travel, tunnels, the list goes on.

Making promises and "it's essentially ready, it's just about regulators" are quite different, if not for Trump he'd be done for securities fraud.


Hyperloop was never a Musk project — it was a back of the napkin suggestion he gave away.

All of those exist or are being worked on, so I don't get it. Except maybe hyperloop, which was abandoned afaik.

What are you even trying to say? That these projects are totally fake? AI generated or something? Like the Moon landing was fake?


Of course they are real, just like Theranos, except that one was less fraudulent.

The one with sales in seven countries and over 50,000 vehicles driving on roads?

> confronted with a world that doesn't work the way you want it to

Sure.

Some of us are just trying to figure out the new rules. What is all this hypercapitalism stuff (aka Muskism) and who are the people (lunatics) pushing us there?

So it's natural to kibitz about one of the most powerful people on the planet. Especially when he's also a world-striding shit poster, antagonizing everyone, demanding a response.

FWIW: the writings of Jill Lepore, Quinn Slobobian, and Ben Tarnoff have been most illuminating. Ditto their misc guest appearances on various podcasts.

So you just hate him. Great. Now stop derailing every thread related to NASA/Spacex launches.

What's your (hot) take on Starship's second stage reusability?

My (noob) understanding is the challenge is achieving reuse (safety, reliability) while keeping the (economically necessary) 100 ton payload capacity.


They are very good in finding money from somewhere to afford all of this.

If this doesn't play out to be reducing costs for the avg american, Musk was able to get funded by the american tax payer nicely.


Musk has saved the tax payer (through the government) billions of dollars on every project SpaceX has been involved with. They have earned money by providing vital Internet services to the disconnected and left behind in rural areas all over the world.

9 Million customers. I know a handful of people who use it as a secondary option who were everythign but 'left behind'

Thats not a lot of people.

And with the satelites risk and disruption to astronomy and the co2 usage, it might have affected more people negativly than positivly.


Hunter-gatherers were always on a knife edge, as they were in equilibrium with the food supply. Killing children in dry years, constant fighting over resources, massacres of entire tribes. Of course they didn't know they were on the knife edge, so what?

Relative terms such as "living on edge" require normative references. It was just business-as-usual, normal life for them, in their own normative reference frame. Just like how cultures in some parts of the world today see things as normal, which would be abnormal to others. It's all your reference frame. There is no permanent or universal norms that can tell what is normal.

Long-range anti-ship missiles of old are also obsolete, they and their launch problems are also too expensive for their vulnerability. A salvo Shahed-style drones launched from expendable unmanned vessels would overload a carrier group air defences way cheaper than old school ASMs from frigates.

New weaponry poses great challenges for these platforms. I don’t know if a swarm of very slow moving drones would be my biggest concern though.

You can afford to spend a few million when you’re taking down billions of dollars worth of hardware.

I would think a simultaneous barrage of maneuvering hypersonic missiles would pose a much bigger threat. A CIWS or three can take down a lot of slow drones.


but if you know there are 3 CIWS, you know they can move the pew-pew pipe at some radians per second this axis, and that axis, you put the drones in a formation to maximize the need for muzzle movement, estimate how many rounds are in them (or how long can they fire before getting overheated)

and send that number + 1 drone.

.

.

of course it's a bit oversimplified, but really with decoys, and putting cheap shaped charges on them ... they can fuck up the launch/landing surfaces, the AA capabilities, there's absolutely no way to jam them if they have the "last mile" set to automatic.

(yes, in theory a dumb and big fireball or good old flack can take out a lot of them, seems trivial, but in practice we don't see that, instead we see faster drones trying to intercept them, currently with FPV remote control)


In theory sure, in practice nobody ever tried to defend a carrier group from 500 Shaheds.

Seems like USN can still do whatever it was made for from this large standoff distance, also seems like it wasn't made for chasing individual nondescript trucks in a hundreds-miles-long mountainous shoreline.

> USN can still do whatever it was made for

One of the primary functions of navies historically has been to secure vital shipping lanes. It’s a big deal that USN can’t seem to fulfill that function anymore.


I'm not sure that the USN would have been any more effective 30 years ago if it tried to make a narrow waterway that is off-shore from a medium-strength world power accessible for safe commercial ship traffic. Effective anti-ship missiles have been around for a long time. Given how understandably sensitive commercial ship crews and owners are to even slight danger, there's just no way to reduce the risk to the necessary near-zero without a prolonged air campaign and/or land invasion to support the naval effort.

A medium-strength world power that it Iran only figured out how to make anti-ship missiles only 25 years ago. They sure got their hands on Chinese ones a bit before that, but that quantity just didn't amount to strait-blocking capability.

> I'm not sure that the USN would have been any more effective 30 years ago if it tried to make a narrow waterway that is off-shore from a medium-strength world power accessible for safe commercial ship traffic.

Yeah I'm not too knowledgeable about this subject, I'm just theorizing.

My thesis is that the only ways that someone could control a waterway was through naval power, air power, or missile power. Air and naval power is negated by a stronger air force/navy, and 30 years ago missiles were only available to a small number of advanced economies nations. Now, high-quality (or at least credibly dangerous to shipping) missiles and drones can be manufactured cheaply by many nations.


It can be safely said that current carrier groups were not built for that, they were built for power projection on land.

The problem is that nowadays essentially nothing can really secure vital shipping lines ...

Ergo navies don't exists.

??

The technology has changed. The navies used to be able to protect shipping. Now the task is much more difficult.

Just as battleships replaced ships of the line, and were in turn replaced by carriers, all due to technology changes.

Maybe there will be drone swarms or some other future magitech being able to protect shipping.

Or maybe the civilization will collapse due to internal (income inequality, widespread employment of AI), external (ecological disasters) or other (demographics, nuclear WW3) pressures before such technologies are developed.


The USN, specifically aircraft carriers, where designed to project power. No one on the world stage is looking at the USNs inability to open the Strait of Hormuz and seeing successful power projection.

Was there ever a risk-free spaceflight? Pretty sure even with this finding this flight would be safer than any Apollo.

You seem to be ignoring the "just to save face" part. I'd argue it would be a worse thing for our bar for how safe it should be to be raised significantly from when we had been in space as a species less than a decade to now that it's been 65 years.

Never risk free , but Soyuz hardly lost any crew over its 50+ years

2/156 lost for Soyuz in 59 years, 2/135 for Space Shuttle in 30 years. Same rate. People often underestimate how intense STS actually was.

The 2 were early, and fewer lives were lost. The shuttle was unnecessarily risky , and NASA was aware from its inception

Yeah, and where is it now?

The next two Soyuz launches are this Wednesday and Saturday.

Saturn 5 had a flawless record. The leftover space shuttle parts which SLS is cobbled together from, not so much. SRBs are inherently dangerous, theyre designed to quickly launch nukes from silos, not people. And Orion is just a typical modern Boeing project. So far its fallen at every hurdle right?

Saturn 5 came close to catastrophic failure at least once. It had partial failures. Its sort of perfect record is mostly down to luck and not launching very many times.

Of course, six decades later, we should be able to do a lot better.


Orion is a Lockheed (CM) and Airbus (ESM) project.

Yeah, I thought it was Starliner on top. I dont know anything about Orion then. SLS is very crappy and disappointing, its using shitty old space shuttle tech, + its ridiculously expensive in terms of payload to orbit, but it will probably work.

I didnt know, cus I just dont give a shit about this stupid project.


If you think NK an US look the same from the outside check your body temp. Source: am outside both.

I'm outside both and I'm not seeing a lot of difference. Main one is that one is threatening everyone with nukes, and the other one isn't making any threats I can understand because they're in Korean.

You chose to suffer not just with touchscreens. That said, it would probably work just fine.

It's honestly kind of amazing how many things seem to never be tested by anyone with long fingernails. My favorite was the time I picked up a video game controller and physically could not use it because the buttons were in a stylish little recess that meant my thumbnail would have to pass through the plastic housing before I could get the button to make contact.

Why would product designers make products worse for most due to self-inflicted conditions of the few?

You do realize that a significant portion of the population is encouraged to grow their nails long, right? Women exist.

Even as a non-woman I sometimes like to have my nails done up nice, and sure it’s my _choice_ just as it’s my choice not to purchase products that are fine excluding a chunk of the market. Out of curiosity, do you remember what controller? We are pretty much all DualSense in this house but I’d like to be aware in case we go shopping for new ones at any point

This was something a friend had in his office when I visited him at Activision back in the late nineties. I have no clue. :)
