If you want to manufacture in space—and bring the products back again—there’s a limited set of options: Wait to go to the International Space Station, or partner with a handful of start-ups launching spacecraft that spend time in orbit before they return to Earth.
But the vehicle that goes to space and comes back to Earth more often than any other is a SpaceX Falcon 9 rocket booster, which made that round-trip 163 times last year and has already flown more than 100 times this year. Now, a startup says it has talked Elon Musk’s space company into letting it prototype an orbital semiconductor factory across a dozen flights with the booster.
