Ich stieß auf einen Artikel über Kürzlich verdrahtet, dass es eine Zukunft für die Herstellung von Dingen im Weltraum statt im Erde gibt.
In dem Artikel wird erwähnt, dass die Mikrogravitation der Erde eine implizite Obergrenze für die Qualität der Produkte legt, die hergestellt werden können – und die Herstellung im Weltraum kann dies überwinden. Die Herstellung von Siliziumkristallen für Halbleiter führt aufgrund der Schwerkraft der Erde zu Verunreinigungen – dies würde jedoch durch die Herstellung im Weltraum behoben. Wie wahr ist das?
Es sagte auch das China machte eine Niobiyum-Silicon-Legierung in der Raumstation. Es ist leichter und dreimal so stark wie Titanlegierungen, die es verwendeten – und es würde in Motoren hyperschonische Flüge auf großartige Fortschritte senden. Es gibt Herausforderungen (brüchig bei Raumtemperatur, die verhindern, dass es heute in Massen erzeugt wird – aber diese werden aufgrund der geringen Schwerkraft mit der Herstellung von Raum im Raum überwunden.
- Ist die Herstellung im Weltraum wirklich ein wichtiges Problem? Wird es wirklich Hilfe schaffen, um Dinge wie Fahrzeuge im Weltraum herzustellen?
- Was wäre die finanziellen Auswirkungen? Würden die ersten Umzugsunternehmen ein Monopol schaffen? Würde ein Unternehmen, das im Weltraum hergestellt wird, einen exponentiellen Vorteil gegenüber einem ausschließlich auf der Erde hergestellten Wettbewerber gewinnen?
- In welchem Zeitraum wäre das realistisch?
Is the future of manufacturing in space ?

Seeing how much lack of resources earth has and how resources space has, so yes definitely.
For the space industry it would be a huge step if they could expand into manufacturing as this would have the potential to expand the market. However in terms of the people on earth the impact won’t be huge as the production volume would be low in the near future. I don’t think we will see vehicle production as this needs a very complex supply chain and it’s still easier to launch is pieces and assemble in space.
Nobody knows the finanical impact until we acutally have it. Due to the high cost to build and low production volume, it could become a monopoly. If it’s used in defense, the might be several nations creating their own facilities. A company might have an edge over competitors, but only in very niche applications.
Time frame would depend on how complex the production facility is. I could imagine that there could be something ready in the 2030s for simple stuff.
We would need to solve the high cost of transferring things to and from space first. I mean it’s cool to imagine the stuff we could make in zero gravity, but if it all costs a million dollars per gram due to shipping, what’s even the point?
No.
Let’s think this through:
– Gather materials
– Load them into a rocket
– Shoot everything into the orbit
– Produce the goods somehow somewhere (space station, rocket?)
– Send it back to earth, it has to land save at a place you can easily reach
– Collect the products and distribute them
Sounds like way to cost and time consuming. Not to speak about the environmental costs and all the risks involved. This PR article is not speaking about all that for good reasons (they only want venture capital)
You would need to be manufacturing something that requires zero gravity and fetches a price high enough to send building sized rockets up with supplies. Making faster computer chips would have to be weighed against just making more regular ones that don’t require a flying building full of explosive fuel in their supply chain.
I personally fail to see how it could be a good use of resources, there are so many low hanging options to improve life and the environment that could use attention first. Why do we need faster computers and hypersonic flights when we force people to work under poverty wages and destroy the same environment the people that could afford hypersonic flights would be going on vacation to see? Who does this help?
How would you do welding in space (or other heat intensive processes) if you can’t dissipate the heat with convection? I assume radiating it away would take a pretty long time. Is there some way to change the dimensions of heat energy similar to how you can do with electrical wattage?
Long term future, yes, though it requires very high levels of autonomous systems
We kind of went to space way, way, way too early. We have zero capability to do anything remotely useful or interesting off of Earth.
It would be like if some guys from Spain discovered Hispaniola in 500AD with longboats. It’s cool, but there’s just no infrastructure nor any ability to remotely enterprise from it.
