UK to Invest Nearly £1M In In-Orbit Manufacturing

UKSA awarded contracts to three companies worth a combined $1.1M+ to advance in-orbit manufacturing.

Details of the contracts include:

  • £300,000 ($410,000) to Cardiff-based Space Forge, which wants to manufacture novel semiconductors in space; 
  • £295,000 ($404,000) to London-based OrbiSky, and its space-grown optical fiber research;
  • £250,000 ($342,000) to BioOrbit, also from London, which experiments with made-in-space pharmaceuticals. 

“By backing these innovative companies to explore manufacturing in orbit, we’re positioning the UK to capture new markets and bring tangible benefits back to Earth—from better medicines, to more efficient electronics,” UKSA CEO Paul Bate  said in a statement. 

Zero-G benefits: In-orbit manufacturing experiments have shown that crystalline materials grow better in microgravity, forming larger and more regular structures that improve the material’s performance. The vacuum of space also exceeds what’s possible in the best vacuum chambers on Earth, resulting in fewer crystal impurities prone to spoiling the crystals’ growth. 

For example, semiconductors made of space-grown materials could boost thermal performance, reducing the need for cooling but also offering increases in computing power. Space Forge, which has plans to grow semiconductor seed crystals in space, recently tested its orbiting demo factory, producing a stream of super-hot plasma in space for the first time. 

Company specifics: It’s not exactly clear what the new funding will go towards for Space Forge, but the company plans to launch its next satellite in 2027, with the aim to return its first batch of space-grown semiconductors to Earth later that year.

OrbiSky will use the funding to design a payload to grow optical fiber crystals in microgravity, to potentially make strides for the telecommunications and medical imaging industries. The company is focusing on the production of ZBLAN fibers. 

  • ZBLAN fibers are a heavy metal fluoride glass alloy that transmit optical signals better than conventional silica-based fibers. 
  • Manufacturing ZBLAN on Earth has been difficult due to gravity-induced breakage. 
  • OrbiSky thinks that made-in-space ZBLAN could transmit light up to 100 times better than conventional optical fibers.

BioOrbit intends to design an end-to-end mission to test the production of new pharmaceuticals. The company says the superior quality of space-grown crystals could enable researchers to create novel drugs, or to improve the efficiency of existing ones.
