UK startup readies new satellite that will make semiconductors in space | Space

A U.K. startup is preparing to send a satellite to space that will manufacture new semiconductor materials that could be used in electronic devices on Earth. 

The company, , lost their first experimental satellite in the failed launch of ‘s LauncherOne rocket from Cornwall, the U.K., in January. Their new satellite, called ForgeStar-1, is about to ship to the U.S. for a launch at the end of this year or in early 2024, Josh Western, Space Forge CEO and founder, told 

Space Forge has recently signed a collaboration agreement with American aerospace giant Northrop Grumman to provide space-made semiconductor substrates that Northrop can then further develop in their foundries. 

Semiconducting materials are essential for all sorts of electronic technologies, but their manufacturing on is costly and energy intensive. The vacuum and conditions of space, however, could allow completely new semiconductor materials to be developed much more efficiently, said Western. 

“Producing compound semiconductors is a very intense and very slow process, they are literally grown by atoms,” said Western. “And so gravity has a profound effect, basically shifting the bonds between those atoms. In space you’re able to overcome that barrier, because there’s an absence of gravity.”

Space, Western added, also provides a perfect vacuum, which is necessary to protect the sensitive material from contamination. In factories here on Earth, this vacuum has to be created by industrial machines. The combination of the microgravity and vacuum of space can enable researchers to create semiconductors that are “10 to 100 times more efficient semiconductors than you have on Earth,” Western added. 

The microwave-sized ForgeStar-1 satellite contains a miniature, automated chemistry lab that will allow the team to remotely mix various chemical compounds and develop new semiconducting alloys once the satellite is in orbit. But rather than sending the materials back to the planet, ForgeStar-1 will beam the results of these experiments to scientists digitally as this satellite is not designed to return to Earth. 

Space Forge's future missions will be able to return to Earth with the products they made in space.

But the company’s subsequent mission, Western said, will be built to survive the fiery return through the atmosphere and bring its products back to Earth. The company will not concentrate solely on semiconductor manufacturing but will use their satellites to host other industrial processes as well. Western said the first returnable satellite might be launched in two or three years. 


The global semiconductor industry is currently worth more than $500 billion and is expected to double in size by 2030. 

“This growth is expected to require investment in high-end advanced wafer manufacturing materials, equipment, and services,” Space Forge said in an emailed statement. “In-space manufacturing offers unique advantages, such as microgravity and vacuum conditions, that can lead to the creation of semiconductors with superior performance and reduced defects compared to those manufactured on Earth.”
