“The work that we’re doing now is allowing us to create semiconductors up to 4,000 times purer in space than we can currently make here today,” says Josh Western, CEO of Space Forge.
Interesting. Having something that can only be manufactured in space would be a real motivation to getting off our asses and back up there.
Hell yeah! Actual useful industrial endeavors are the way we finally get humans off the planet, this is the way to the future. Once there’s a reason for industry in space, there’s a reason for support industries, construction, material supply, fuel supply, maintenance, etc. With those support services comes reasons for people to start to actually live in space, where they work. And from there, we can start to spread our legs and really “move in” to solar system, and the story of the human race truly begins.
And how much space junk will end up there? Cleaning up afterwards costs more money and long term thinking isn’t something shareholders care about over more profit today.
The tech is interesting, hopefully governments across the entire planet regulate it well enough. Although at the same time, its not like we really need to care either. In our lifetime its not like any of us are likely to be able to afford to go to space anyway, but it would probably be a good idea not to ruin it if we have a choice.
It shouldn’t be too hard to engineer orbit decay as a feature to avoid space junk.
Consider that space junk is so sparce it’s not really much if a consideration for launches. It’s like the rings of Saturn: the likelihood of a collision is so remote that they didn’t even consider it when we had a satellite move through it.

I didn’t realize that, what mission is this your talking about? Cassini?
Yes, Cassini
Pretty sure its the asteroid belt, not planetary rings, that you don’t really need to think about when passing through.
And yeah, it shouldn’t be too hard and yet look at all the junk already up there. Hopefully they can just be required to keep to very low orbits that decay rapidly.
The satellite Cassini passed through a less dense section of Saturns rings and was met only by dust particles, despite the rings being populated by objects between 10 meters and the size of mountains.
It’s my understanding that the idea of a dense asteroid belt (the kind Han Solo might try to hide in) is basically pure fiction, they don’t exist. However… that is essentially exactly what some parts of a planetary ring system may look like up close. So perhaps Han could hide in a planetary ring.
I’m just confused about what products can be manufactured completely autonomously, in a 0G environment, and are profitable enough to make space-based manufacture economical.
Solar energy for computation perhaps, but cooling would be too expensive.
In an existing ecosystem of space mining and processing of all required elements, with no need to exit gravity wells, could be microchips. I don’t think we are closer to that than Vinland settlers were to thirteen colonies.
Anything, because it’s a hell of a lot cheaper than launching finished products from Earth.
Pretty interesting. How come they can get 1000c in space but not on earth? Doesnt the vacuum of space make it hard to retain heat?
Vacuum is a perfect thermal insulator. The only real losses are radiative.
Edit: From Stefan-Boltzmann: up to (not sure about emissivities, but could be down to 10% of this) 100kW for a black body of 1m diameter at 1000C.
I’m completely unaware of the science around it all but none the less its exciting stuff, i hope to read more about it as things progress.
We can finally make endo steel chasis!
Finally, like SciFi series ‘Star Trek’ & Etc.
Only problem is all the garbage already in space, damage! I assume better for the environment, even with environmental cost putting all that into space. Robots not our species working there.
Ew… Aliens don’t need more human garbage. Have you seen how much space junk we have?.. We already look like the universe’s junk yard.
