United Semiconductors' Second Crystal Growth Payload Successfully Launched to the International Space Station from Cape Canaveral on Northrop Grumman's NG-23 Resupply Mission

United Semiconductors LLC (USLLC) is proud to announce the successful launch of its Mission 2 crystal growth payload to the International Space Station (ISS). This marks a major milestone in advancing semiconductor crystal manufacturing in space.

Following the success of Mission 1, which demonstrated the transformative effects of microgravity on semimetal–semiconductor composite crystal growth, Mission 2 aims to further expand the scope and scale of space-based semiconductor manufacturing. The payload—designed, built, and qualified by USLLC—was successfully delivered to orbit and is now safely integrated aboard the ISS.

Mission 2 will pursue three key advancements:

1. Shorter on-orbit manufacturing durations.

2. Increased production volumes.

3. Engineered microstructural control to improve material properties for high-performance semiconductor devices.

Crystals grown during Mission 1 have already yielded 2× performance gains and 10× higher device yields compared to current terrestrial technologies. Building on these results, Mission 2 is expected to accelerate the transition toward commercial-scale production in microgravity, setting the stage for sustainable in-space semiconductor manufacturing.

According to Dr. Partha Dutta, Chief Technologist at USLLC and Principal Investigator:

“The success of Mission 2 marks a defining moment for space-enabled semiconductor technologies. With microgravity providing an unparalleled growth environment, we are witnessing a new frontier in material quality, device yield, and reliability.”

Dr. Geeta Rajagopalan, President and CEO of USLLC, added:

“This mission validates the vision of a robust commercial space economy in low-Earth orbit. By manufacturing advanced semiconductor materials in space, we are laying the groundwork for U.S. leadership in critical technology sectors—from radiation-hardened space electronics to AI, sensors, and advanced computing.”

The Mission 2 investigation is being conducted in NASA’s Solidification Using a Baffle in Sealed Ampoules (SUBSA) furnace, with implementation partners CSS Inc., Redwire Space Technologies, Inc., and Axiom Space. The project is supported by NASA’s In-Space Production Applications (InSPA) program under Contract No. 80JSC022CA005, managed by Mr. Kevin Engelbert, InSPA Portfolio Manager, NASA/JSC.
