Having worked on these systems, datacenters in space still don’t make any economical sense to me. Cost of shipping, additional power and thermal limitations/challenges, much greater radiation environment causing corruption and premature hardware failures, and little to no maintenance/upgrade opportunities. Zero sense
INB4 chumps discover that cooling hardware in a vacuum is, in fact, quite difficult.
Lol, this is the truth. There are many cool opportunities for industry in space, but I gotta be honest, I don’t think datacenters are one of them…
In deep craters near the Moon’s poles, permanent shadows keep the surface even colder — NASA’s Lunar Reconnaissance Orbiter has measured temperatures lower than -410°F (-246°C)
That’s not the issue, though. In a vacuum there is no medium with which to carry the heat away. You can’t send it into the air with fans or heat sinks because there isn’t any air.
At least on the moon you could sink it into the ground. But in orbit you don’t have that luxury. This is a major problem that spacecraft and satellite designs need to work around, and much effort is expended in that department.
Even though space is generally considered “cold,” in the absence of a medium to sink heat into the best you can do is rely on infrared radiation which is not terribly effective.
It’s done for smaller parts with peltiers nowadays. Not that efficient, but there are few options. If you sink it to a large enough surface, it will radiate away.
And there inlies the problem. Big surfaces are expensive to ship
What if me make a heat laser? /s
You joke, but actually that is a thing.
When research projects involve super-cooling a substance, after you’ve done as much as you can with convective cooling, researchers will sometimes use lasers to cancel out vibrations within the substance, and cancelling vibrations essentially equals cooling.
What would they use it for? The 2.5 seconds of latency would be too high for most uses. Cooling will be very difficult with no atmosphere. Solar power will be hard since night time lasts two weeks. Radiation will damage electronics unless they bury them.
No hurricanes, earthquakes, floods, or other types of disasters on the moon. Asteroids are rare enough now that they basically don’t count.
Latency is high but it doesnt matter for data redundancy.
Ok… Data redundancy is a possible application… I will tentatively say that’s a feasible goal, if still probably a stupid one.
I mean, how often do data centers upgrade storage drives? Cause the cost of doing that in space is… unreasonable.
It would depend on how critical the data is and if the cost benefit analysis breaks even or tips in favor of the moon. I would imagine housing state secrets up there would be reasonable, and documents (text files) don’t take up a huge amount of space. Video would be more challenging. But realistically you could probably store all of the Secret and Top Secret documents across a few servers with maybe 5 drives in a RAID config each. Probably even a single NAS-like solution.
I mean, yeah, you could do that.
I’m not sure if it would be better than a secret underground base… But you could do it.
With an underground base you could even have the one connection to it be a hard-line, not wireless. You could construct it with a smaller crew, easier to keep under wraps. And I expect that would still be less than 1/100th the price of building it on the moon.
Anyway, I do think the ultimate off site data storage location is a pretty entertaining idea, i’d bet it could make sense for some things, I just can’t imagine what.
Except radiation is much much higher around the moon, resulting in greater corruption events
Craters at poles are in permanent shadows with -200 degrees permanently
Anything that needs a lot of data. Same reason you’d download something to your PC instead of streaming it.
Also for local processing before upload. If you have a huge data set that compresses well, it’s much better to compress first, then upload to Earth.
Seems like the moon would be close enough for our standard IPv6 TTLs to work, but it seems more likely that we will have to abandon domain names in favor of something like IPFS, since it’s a resource locator instead of a location locator. If you were on Mars, for example, you would not want to have to contact Earth every single time you wanted to load a web page. And so you would contact Earth the first time to load it. And then it would be saved locally. And so anybody who requested that page in the future would talk to you instead of Earth.

Don’t ISPs already do something like this to save on bandwidth on their side? Just saving local copies of commonly accessed files.
At least I remember hearing about that a decade ago, I wonder if that can still happen now that there’s basically https everywhere.
But at any rate, I believe there are at least well established methods for that.
Sounds like some sort of decentralized federation of server resources. I don’t know, seems a bit advanced. /s
Nothing would stop you from running a DNS server on Mars and handling requests locally.
The problem isn’t the DNS requests. It’s the data synchronization that would have to occur if you were accessing a service hosted on Earth.
There are many places on Earth where DNS servers have high latency, low bandwidth, and intermittent connectivity, yet still function fine. It’s already a solved problem.
It’s called caching and it’s been mostly solved for decades (except invalidation).

Well I guess that’s what it takes to make Microsoft’s ocean bottom data center look reasonable. 😬
I wonder what the moon’s top level domain name would be?
.luna
We’ve had .moon and .mars since 2009
Edit: Looks like r/CryptoCurrency has recently acquired the .moon TLD.
Because of course they have. All they give a shit about is getting rich on fiat gains. They don’t give a shit why crypto was actually created to begin with. But that’s a whole different rant.
