Musk reveals plans with Varda for first space factory
Benefit: microgravity. For manufacturing 3d printed organs, special-purpose semiconductors.
2023 plan: 3 months of Varda's spacecraft being up there, then a reentry capsule will return the finished product. 2024 two more factories to go up.
Varda is also building it's own capsule to return up to 100kg from space. They're focusing of frequency of reentry because it shows how they can return value after sending raw materials to space.
Varda hasn't said what it will produce up there (and might not yet know because they might not have a contract). Pharmaceuticals and fiberoptic were mentioned.
