BBesxar builds reusable orbital Fabships that manufacture ultra-pure semiconductor substrates in space vacuum to supply power and AI chips without Earth-side clean rooms. Small microwave-sized Fabships attach to Falcon 9 boosters, expose wafers in orbit, and return with the booster, with in-orbit processing including heating and multi-material deposition to produce qualification wafers. The approach leverages in-space fabrication on launch-vehicle‑attached Fabships and early data from orbital samples, supported by a SpaceX deal for 24 Fabship payloads and investors backing the effort, positioning it to scale toward larger, Starship-class fabs. The goal is to continuously produce substrates for data-center, robotics, and EV power chips via on-orbit manufacturing.

Besxar's orbital chip plan clears first SpaceX flight test. Ex-OpenAI researcher Ashley Pilipiszyn's startup proves its space chip canisters survive a Falcon 9 ride. Last updated: September 9, 2026 8:30 pm Besxar, a startup founded by former OpenAI researcher Ashley Pilipiszyn, has completed its first flight test of hardware designed to make semiconductors in the vacuum of space. The mission flew July 5 on a SpaceX Falcon 9 carrying Starlink satellites, with semiconductor wafers in Besxar-built canisters alongside samples for researchers at the University of Virginia and the University of Texas at Austin. The flight proved the canisters could let the vacuum in while keeping out contamination, including atomic oxygen in low Earth orbit, and that the wafers survived launch and re-entry aboard the returning booster. Besxar says the test gives it flight heritage for its fabships, small canisters designed to carry and process semiconductor materials in orbit. Besxar has raised almost $14M, including a $9M seed round led by Dauntless Ventures and Overture VC. SpaceX is under contract to fly 12 missions for the company, and the second is expected before the end of the year. Pilipiszyn argues space offers what Earth fabs buy with billions in pumps and pressurized clean rooms: a ready-made vacuum. It is more cost-effective to go where the physics already works, she told TechCrunch. For the deep-tech ecosystem, the demo is an early data point on whether orbital manufacturing can move beyond experiments toward real wafer processing, and whether the chip supply chain will ever include a stop in low Earth orbit.
Space manufacturing startup Besxar has raised $9.35 million in seed funding led by Dauntless Ventures. The company develops technology to manufacture semiconductors in orbit, leveraging the natural vacuum environment above the Kármán line to bypass the expensive infrastructure required for terrestrial cleanrooms. Besxar recently completed a milestone suborbital flight aboard a SpaceX Falcon 9 rocket, carrying test wafers to validate its space-based manufacturing approach. The hardware successfully demonstrated its ability to protect sensitive materials during atmospheric re-entry. The fresh capital will support Besxar's mission to produce higher-quality, cost-effective semiconductor components for commercial markets. The company has contracted a series of twelve suborbital missions with SpaceX, with a second launch planned before year-end.
Besxar, a startup founded by former OpenAI staffer Ashley Pilipiszyn, is developing an orbital semiconductor factory using SpaceX Falcon 9 rocket boosters. The company has raised nearly $14 million, including a $9 million seed round led by Dauntless Ventures and Overture VC. Besxar aims to manufacture semiconductor precursors in space, leveraging the vacuum environment to avoid the costly clean room infrastructure required on Earth. The company's first two "fabships" flew on a July Starlink mission, successfully protecting wafer samples from contamination. The flown samples showed less particulate matter than terrestrial wafers. Over the next two years, Besxar plans to iterate its technology across a dozen flights, with the ultimate goal of operating larger fabrication facilities aboard SpaceX's Starship. The startup intends to supply leading chipmakers with wafers for advanced chips used in data centres, robots, and electric vehicles.
