It’s really hard to put a computer into space… so hard in fact that laptops on the international space station are treated as effectively disposable. So when the folks at HPE wanted to put a SERVER on the ISS, people were a bit skeptical… and it turned out even with the help of KIOXIA’s fast and reliable storage devices, to be harder than they thought.

And I can tell you... they basically looked like big white rectangles. Researching the tech behind them is honestly more fun. But as far as computers surviving in space... my grandfather did work on two such computers that are still working today, more than 40 years after they launched... the Voyager probes.

there are a few things called satellites up there also. not surprising they also have computers up there. the big problem is the ISS seemed to be planned and executed with long slow and dangerously bad design and practice. everything from the station not being completed till after it was supposed to have reached end of life. they run at low pressure resulting in converting super fit & healthy humans into very weak people. they could dissipate heat from computers to heat the station.

@@chrisoakey9841 Utter nonsense. "they run at low pressure resulting in converting super fit & healthy humans into very weak people." That in no way weakens people, it's lack of gravity that does it, same as bed-ridden hospital patients. "they could dissipate heat from computers to heat the station." The problem is Not heating, it's cooling. Without sufficient cooling, the ISS would overheat and cook teh astronauts alive from getting too hot. The computers also need cooling, and so are limited by the total ISS cooling budget, which is limited by the size and number of their radiators. Since the ISS continued longer than planned, they kept bolting on new unplanned additions. things take years to design, test, validate,etc. before flown, and so something planned in the 1980s and initially designed in the 1990s is going to be obsolete 35yrs later, who knew. The ISS was initially developed in the days before personal computers, internet, and other technology being commonplace. Even most electronic calculators in teh early 1990s were still very crude devices, with 2-line calculators and more scientific computing features coming along later.
@paratus04
@paratus04 Ай бұрын
11:41 One correction. The cooling loops exchange heat with the External Thermal Control System radiators (the two sets of 3 radiators closest to the modules along the truss) The Photovoltaic Thermal Control System Radiators are the 4 radiators mounted between each pair of solar arrays. They only provide cooling to the electronics for their respective solar arrays. This makes sense because they are mounted outside of the 2 Solar Alpha Rotary Joints which spin the 4 port and starboard solar arrays 360 degrees every orbit. It’s hard to pass a fluid through a rotating joint.

Not really surprising. Think about a submarine - the other kind of pressure vessel we use as a species that deals with dramatic changes. The ISS deals with a total pressure differential of ~1 atmosphere. Relatively speaking, it's easy to keep the thing as one solid piece. The difficult part is the lack of atmosphere. Take a hinge - like a standard door hinge, two pieces of brass or whatever, that slide together. In space you would find it has the awful habbit of sticking after you open it a few times, and by sticking I mean suddenly welding itself together as the oxide layer is rubbed off, exposing bare smooth metal surfaces that don't know any difference than to presume they are a single continuous piece of metal and suddenly: You can't easily move the hinge. This isn't a problem on earth - any oxide layer that does get removed, quickly reforms. But where you have no atmosphere? The problems in Space aren't so much about bleeding edge technology - it's about solving problems that you didn't know would be problems. This is why Reliability, trumps basically all else. You need to know it will work.

Hi I'm working in aerospace, I can talk about just a couple of things: 1. People think of space as cold, but it might not be as cold as you think. Temperature in low Earth orbit (LEO) can be -60 to +120 C depending on how much direct sunlight you're receiving. Linus' point about having no air to convect heat away is a pretty big deal - that's why you need massive radiator panels. 2. NASA and incumbent space agencies tend to be risk-averse and want to see SIGNIFICANT verification of functionality at every level, particularly when humans are involved. That's probably one reason why they don't use Starlink - the technology is simply too new and maybe there's some technical or bureaucratic inertia to overcome. It's also why tech in space tends to be pretty old, even if it's launched today. US agencies like to see flight heritage. So even (as a silly example) if Ryzen 7600 is better than Intel Core 2, if these agencies see that Intel Core 2 provides everything they need, they're more likely to pick the Core 2 over Ryzen 7600 because they KNOW it'll work. This is compounded by the fact that the rad-hardening process takes a ton of money and time, so you often end up sending surprisingly old tech into space. Newer commercial companies and smallsats are trying to use newer tech though. 3. Power budget is super important. One reason that it's so tight is because solar panels degrade over time, especially in space, so the power available to the ISS is decreasing over time. 4. Bit flips are MUCH more common than on Earth, that's why rad-hardening is important. I had a professor whose research specifically tried to ameliorate the effects of bit-flipping. 5. Not necessarily tech related but it's true that space vehicles need to balance physical practicality versus human preference, e.g. convenient orientations versus "needed" orientations like Linus mentioned.

A friend of mine is a physicist who used to work at CERN and, as part of her job, assembled sensors for the particle collider. And despite the sensor's specific purpose being to measure the products of a collision, one of the issues they had to deal with was these particles causing bit flips and other issues when passing through the chips inside the sensors. So what she told me they did was to irradiate the chips before putting them in because this somehow increased protection from the effects of the particles passing through. Or better put less susceptible to damage. She tried to explain it to me what happens in detail but this was long ago and I didn't understand half of it, so I might be talking BS here. Though I wonder if NASA/ESA also do something similar to their chips. But I guess this would only be useful for heavier particles than gamma radiation, which I guess is the main problem in space. All that being said, computing in hostile environments is both very interesting and potentially very frustrating as entropy slaps you in the face.

In case you're interested (they mention "irradiation qualification of ASICs"): indico.cern.ch/event/774201/contributions/3429235/attachments/1875763/3088566/iWoRiDtalkDette2019.pdf Though since you're here and could provide some background knowledge: Since this is basically just testing/sorting chips, wouldn't this also make sense for any kind of ASIC/CPU/GPU NASA sends up there? Or do they do that already?

​@@XanatosDavid Somehow my last response was deleted, probably because I linked to a PDF from the CERN document server with slides my friend sent me back when she told me about this. But thank you for explaining and of course you are completely right and I remembered it wrong, it was basically just done to sort out the chips that would be most affected by radiation. In the slides she sent me back then she called it "irradiation qualification". But since I have another physicist to ask now: Do you know if NASA performs similar tests with the computers they send up? Would make a lot of sense I guess. Oh and in case anyone wonders, the PDF can be found on the CERN document server, it has ID 2686279.

Something like this is actually common practice for all industrial grade (and military and aerospace grade of course) electronics. Most component failures tend to occur early, so the parts undergo a stress test inside a climatic chamber, cycling through the temperature and humidity ranges the parts are specified for. It's called a "burn-in". This is of course expensive, but it's a lot less expensive than fixing a train stuck in some tunnel in the alps or a plane crashing.

Speaking as someone that helped put about 150 satellites into LEO, in my opinion, space hardening the hardware really only applies when you intend on a super long lifespan - which means you also have no reliable de-orbit plan (so you fully intend on being space debris). For something with a lifespan of under 10 years, you just need some redundant systems and really good error checking in your software. Software based hardening is 100% a thing and way cheaper.

Always depends on the workload, but it is crazy how many workloads can fit in the Rancher SUSE "Cattle not pets" model for services where you build them to deploy as stateless as possible to allow for processes to spin up when needed to process data and crash with no loss if they go down. Again redundancy, plan for failures to happen, and then you can start to tighten your tolerances to save costs and not just to get it to work at all!

During the "space race" it was kind of a war with russia and some lives lost were acceptable. That's not the case anymore. That's why things are over engineered and thorougly tested. Because there is no triple a or plumber in space.

Having just wrapped up my Master's thesis, which dealt with working within the constraints of edge compute systems for AI in space deployments, this was great timing and a very enjoyable video. Great work on really putting into perspective the constraints one has to work within when dealing with computer systems in space. The university I attended has a lot of projects under NASA funding, so its always nice to hear that NASA's big ISS projects have to deal with many of the same sorts of constraints that we have to put up with on our smaller space platforms.

the private sector computers are far more advanced than anything the gov has developed.

NASA has *always* outsourced a ton of stuff to private contractors. e.g. take the Apollo Guidance Computer (AGC). The MIT Instrumentation Laboratory designed the computer's hardware, OS and UI. Raytheon did the manufacturing. Fairchild Semiconductor pioneered the first mass-producible ICs in 1960, and the AGC was the first computer to use them. Of course these were still primitive-one flatpack chip roughly 20mm² might contain two 3-input NOR gates, for a total of 6 transistors. The AGC's memory was even wilder. Its RAM was magnetic core memory (typical for the time) but its ROM was core rope memory. The AGC had 6 core rope modules. Each contained 512 iron/nickel cores (donuts 0.249" in diameter, about 6.3mm) and 192 "sense" wires. For every core, each sense wire either threaded through it (representing 1) or around it (representing 0). Cores had additional wires for address selection and reading out. All of this threading was done by hand-Raytheon had a factory full of needleworkers threading data into the ROM, bit by bit. They did this because even though core rope memory was incredibly labour-intensive to make, it had unparalleled information density, about 5× that of the magnetic core memory used as RAM. When going into space, mass and volume are paramount. It also happens to be resilient to bit-flips ;)

Idk if you've done a video on Mars rovers or their computers (a quick KZfaq search suggests not 🤷‍♂️) but the radiation hardening required for those sattelites and computers that go beyond LEO are insane. For instance, the Perseverance rover launched in 2020 has the equivalent of a late-90s PowerPC Mac CPU. The ISS and other LEO sattelites don't need this because they are below the Van Allen radiation belts that capture most of the sun's harmful radiation. On another note, I don't think the wider public realizes how difficult it can be to change hardware out in space. Every spacewalk takes multiple hours and you only get half of the work done that you could here on the ground. And every upgrade (like adding Starlink antennas) would require a spacewalk. The work that goes into computers and equipment that goes into space is amazing. Awesome video, love that you could work with NASA and bring light to a wider audience the awesome things they do. 😁👍
