>if Google can't make it work for gaming Windows certainly can't do it at the OS level
Gaming is by far the worst place for them to start if they're trying to get people to adopt desktop as a service. Video games rely so heavily on immediate feedback that any kind of latency just feels like shit—people have no idea how much time and money and effort goes into client-side prediction to make online multiplayer games feel good to play. The client-side prediction to make an OS-as-a-Service is pitifully easy in comparison and if the latency is what Starlink actually promises it may not even be necessary at all.

Or is it? To me it's just a trick to get people actually reading into science. You go to school, "learn" a lot of garbage, but you forget all of it. Then all of sudden, a bunch of people start showing what seems to be evidences that the earth is flat. What do you do? You can either

a) bark at them like a guard dog

b) read into the concepts being presented, about how models are constructed, etc.

What proof was show to you to prove that the Earth is round? A cgi composite? If that's all it takes, you could have been taught that the earth was flat and you'd firmly defend that belief not because it's true, but because you accept arguments of authority. Meanwhile they'll try to make their physical experiments that sometimes give results that contradict what they think, but that sometimes also contradict what people "on the other side" would expect.

At least for SpaceX, being able to deliver +50t to anywhere in the solar system (practically speaking) is a pretty powerful thing to have. For just probes, the amount of mass shedding needed to fit on current anemic launchers is astounding. That requirement significantly drives up the cost of the probes as it requires advanced materials and manufacturing. Which then drives up the cost even further because now there's more risk management required to make sure that the highly expensive probe works. Lifting the mass restriction will allow for cheaper and faster built probes that would be just as good as current probes. I think SpaceX has it down if they can get Starship to work.

I doubt that because it can't be guaranteed that every country is going to play nicely with space. China has shown to not give a damn about what the international community thinks and they could happily take over space if it meant having an advantage over other great powers. The US shutting down SpaceX and every other attempt to open up access to space means that other countries will just do their own "SpaceX" and leave the US behind.

I was also taught that flat 7-up would cure a cold and I think that's retarded too because I was also taught that circumstantial evidence isn't enough to "prove" anything. I could "prove" that there's no way a conspiracy of the scope of flat earth could exist just by sharing a secret with a handful of friends and seeing how it takes to get out.

If that's the case, then how would the US and Russia challenge China in this hypothetical scenario? Once something is in space, the only thing that can stop it is something else in space. The Chinese would be able to send 50t to the moon with the LM-9. That's enough to send some serious base making equipment. Russia has nothing that could send anything substantial. The US has the SLS, but it's payload is about half that of the LM-9 and it's launch rate is pathetic. If the LM-9 can launch even as fast as the SLS, then the Chinese would win access to BEO.

The Chinese don't anticipate having LM-9 running until well into the 2030s. The Russians are working on two different super heavies - Yinesei, a moon-capable Soyuz derivative that they intend to have in service by 2028, and their existing Angara A5 rocket with a new second stage that can haul 40 tons to the moon.

There are easier amateur liquid rocket propellants. Acetylene is usable, but it has downsides. The biggest one is that it's unstable (it tends to decompose) which makes storage tricky. If you're looking for a light hydrocarbon, then pentane may be better as it's stable and liquid at room conditions. Stepping away from hydrocarbons, the alcohols are great as fuels. Ethanol is easily obtainable and can be watered down to regulate the temperature of the rocket engine. Methanol can't be watered down and is harder to get, but it offers much better performance.

In my experience. Dealing with highly oxidizing substances was a massive headache. They require specialist materials, lubricants, oils, handling procedures, and more. Cryogenic fluids were also a headache to deal with for the same reasons. Dealing with both at the same time was even worse as materials that can both handle oxidation AND extreme cold are both expensive and rare for an amateur to get. For example, just getting ball valves required special ordering from Israel with an 8 week lead time. Picking something like nitrous oxide as the oxidizer will be much easier to handle.

Storing acetylene is arguably a bigger pain than hydrogen. Welding cylinders are filled with activated carbon and acetone where the actual acetylene is dissolved at a pressure af about 12 bar. Try to compress it without that - it goes boom. Try to compressit more even with all that - it goes boom. If you're handling a cylinder and feel it's getting warm out of nowhere - crank the valve open and fucking run.

If your actually reusing your engines to a significant degree (BE-4s are supposed to be good for 25 flights) 42 should be more than enough.

At least that's what they tell us in training every year. You're also supposed to carry it outside and pour cold water on it (or snow if it's winter) and only run if it doesn't help. Apparently the heating starts when the filling goes a bit bad so the reaction happens in a small volume enough for the rest of the cylinder to act as a heatsink at first and prevent it from going boom right away. It's essentially a ticking time bomb at this point still.
Luckily we don't deal with that shit in practice, only with supercritical co2 and occasionally some nitrogen for drying lab glassware.

I just don't understand this reusable legislator meme.

The amount of money you can save from reusing representatives isn’t enough to justify how much harder it makes it to pass the difficult bills that usually make money in the lawmaker world. I’m sure one day reusability will be more effective, but the truth is that when you have all the challenges that come with political science in general, it’s almost always much more effective to throw away the legislator after it’s done its job than to figure out how to make recovery part of the mission. I know of no major technology on the near term horizon that would change that.

Even if reusable legislators are possible now, but when reliability is THE number one priority (in this case the appropriations bill takes up 2/3rds of the cost and the actual representative only 1/3rd) it makes absolutely no sense. Like, look at this legislator (pic related). This represents some of the most advanced technologies in the constituents world. Do you honestly think that such a complicated machine can be made tough and reliable enough to be reusable? I doubt it. Best example in my opinion is condoms, sure you could reuse them but making sure that they do not suffer a drop in reliability will cost a lot of money and time.

Just because some country made reusing legislators popular, then that doesn't mean that we will have the sci-fi future of millions of laws per year. We'll be lucky to see more than a couple dozen per year. Dial down your expectations, don't buy into the 'reusability for legislators' meme.

I just re-checked our safety manual and it actually says both but doesn't go into much detail. You should limit the flow rate to below 25 l/min during normal operation, but crank it open all the way if it starts heating. My guess too much flow can indeed end up in boiling and loss of acetone (which is what makes the filling go bad and consequent loss of stability) but when the bomb is already ticking the filling's fucked anyways and you should only care about dropping the pressure as fast as possible since it's stable by itself below 2 bar.

Agreed, in general. Luckily Starships are more than tall enough to simulate a full G if they're spinning while connected ASS TO ASS. You could start the spin low at just 2 RPM, slow enough that even people who normally feel motion sickness wouldn't suffer any negative effects, and over the course of about a week ramp it up to 4.2 RPM, at which point you'd have a full G at the nose of the ship and somewhere around .5 or .6G in the "lowest" decks closest to the center of spin. If you slowly increase the spin, people will have time to acclimate between changes in spin and thus basically anyone except for somebody who is already chronically prone to motion sickness wouldn't have any problems.

Then you would manipulate your RCS thrusters accordingly to spin around the two ship's common center of mass. You could spin even slower then and achieve the same effect.

It is easier to maintain health in at least some amount of gravity. It is true that muscle and bone loss can be combated now with resistance exercise however there are other problems as well. The circulation of blood and lymph is hindered in microgee because humans did not evolve their fluid circulating systems in microgee, a lot of our plumbing has grown assuming it's always being pulled down by 1G. Injuries or illness (possible in a long term space mission) would also be exacerbated in microgee, for example bleeding injuries cannot drain properly in microgee and the lungs cannot properly expel fluid in microgee, which would make pneumonias extremely dangerous in it. If any of your astronauts caught the space Kung Flu in microgee they'd be fucking goners, so simulated gee is desirable.

I don't understand what roblox is or does, but it came up when I was searching for information on numerical integrators and it had some handy tips related to their use in cloth simulation. Since you can do that in roblox, write up FEA and particle hydrodynamics and simulate it woobling around with fluid inside. Although you should really calculate the natural frequency of it properly.

Are they amazing? Are they, really? To me they seem like a solution to the problem we've had since the Shuttle era that we're just getting around to solving forever, which is of course maximizing living space for a given expendable rocket's launch mass capacity. You know what we'll be able to do with Starship? Mass produce hundreds of 8 meter wide, ~12 meter long steel-can habitats and dock them together in orbit to do whatever the hell we want. Shortly afterwards we'll be able to launch rolls of steel into space to manufacture truly large single-module stations and deep space ships from.
In light of these rapidly forthcoming capabilities, what is so amazing about a habitat that can inflate to roughly 200% of its packing volume after reaching space? It's a total dead end technology.

Your wrong on all accounts here, considering it’s all but decided now that ULA’s Vulcan will launch before New Glenn does. Furthermore, BE-4 doesn’t actually run on pure methane like Raptor does, it runs on Liquefied Natural Gas (LNG) which is a mix of methane and ethane.

Expandables give superior mass-to-volume ratios, so if you build say a 50 ton steel can and a 50 ton expandable hab made of mostly para-aramids, insulation and a thin steel internal skeleton, the expando-hab will grant you substantially more pressurized habitat volume per ton of material used. It is also more durable (note I say durable in terms of it's ability to soak up micrometeor hits and radiation). Expando-habs so far are also massively less expensive compared to the current aluminum/steel can habs used by previous stations and the ISS, and while you can skylab it up by refurbishing a hollow steel shell with the necessary equipment for life support, I don't think that will be very safe or sustainable in the long term, permanent habitats should be purpose built for their functions.

My answer to both is: why wouldn't you? It doesn't really matter that there are theoretically more optimal things that you could put in orbit, because those things are more expensive, take longer to build, have better things to do (crewed starships), etc. Cargo and tanker SS will inevitably hit end of life and have to do something.

It will be cheaper but it will also be substantially more hazardous in ways which it doesn't need to be. In addition expandohabs are already projected to be enormously cheaper than current custom aluminum can habs, the price gap between a steel can hab and an expando hab will be very small compared to the price gap between both of them and a current specialist custom hab for the ISS or any other contemporary space station.

Can someone explain wtf header tanks are for, and if the other tanks boil off why not just make the header tank as big as the normal tank. Then you don’t need two separate tanks.

>rocket fuel residue
the oxygen tank residue is literally a head start on your breathing air, and the methane tank residue is harmless
it shouldn't be dangerous as long as you start mixing with nitrogen first

Earth surface is 3 mSv/year average. Some places where people live long term have ~ tens of mSv, with no apparent bad effects. Some places where people do not live but visit (beaches) have 100 mSv.

ISS is 150 - 300 mSv. Mars surface is roughly the same as ISS. Deep space is 300-600 mSv.

Only because pretty much every spacecraft today and in the past had to respect tight mass budgets. If extra mass if available for beefier structures and triple redundancies, then tiny fuck ups would just be inconveniences.

Modern planes have vocal warning alarms, often in a pretty strident tone of voice, it is known that a pilot may be more likely to pay attention to their alarm if it sounds like another human voice berating them. In addition, there are a multitude of different electronic sounds a plane can produce when something is wrong, in the heat of the moment a pilot may forget what each one means and what they have to do, a human voice snapping out a simple command or warning in just a few words is effective in reminding them what to do. One of the other Anon's mentions bitchin' Betty, a nickname for the AWS in FA-18s, because it sounds like your plane is snapping at you like a fed up mom. It's relevant to Starship because Starship is pulling a maneuver which would make the EGPWS in a normal aircraft go fucking ballistic.
