A former NASA engineer with a PhD in space electronics who later worked at Google for 10 years wrote an article about why datacenters in space are very technically challenging:

I don't have any specialized knowledge of the physics but I saw an article suggesting the real reason for the push to build them in space is to hedge against political pushback preventing construction on Earth.
I can't find the original article but here is one about datacenter pushback:
https://www.bloomberg.com/opinion/articles/2025-08-20/ai-and...
But even if political pushback on Earth is the real reason, it still seems datacenters in space are extremely technically challenging/impossible to build.
We don’t even have a habitable structure in space when the ISS falls, there is no world in which space datacenters are a thing in the next 10, I’d argue even 30 years. People really need to ground themselves in reality.
Edit: okay Tiangong - but that is not a data center.

It's curious that we live in a world in which I think the majority of people somehow think this ISN'T complicated.
Like, have we long since reached the point where technology is suitably advanced to average people that it seems like magic, where people can almost literally propose companies that just "conjure magic" and the average person thinks that's reasonable?
It's not just "very challenging", it's "very challenging and also solves no actual problem we face".
It's not like launching stuff into space doesn't have pushback, either. See: starlink satellites.
Yeah but he’s an expert his opinion can be dismissed bro this is 2026
"Technically challenging", a nice way to say "impossible"
> It(Solar) works, but it isn't somehow magically better than installing solar panels on the ground
Umm, if this is the point, I don't know whether to take rest of author's arguments seriously. Solar only works certain time of the day and certain period of year on land.
Also there is so limited calculations for the numbers in the article, while the article throws of numbers left and right.
No one is interested in excuses on why it can't be done. Were in interested in the plan on how they plan to do it.
The guy is saying satellite communication is restricted to 1Gbps ffs. SpaceX is way past that.
It's much easier to find a country or jurisdiction that doesn't care about a bunch of data centers vs launching them into space.
I don't get why we aren't building mixed use buildings, maybe the first floor can be retail and restaurants, the next two floors can be data centers, and then above that apartments.
