York Space Systems announced the close of its acquisition of Solestia. "Controlling our supply chain is a core part of how York delivers for our customers, and space solar has been a critical gap the industry has largely ignored," said Dirk Wallinger, CEO of York. "Solestial's solar cells are produced in the U.S. and will ultimately source raw material from U.S. suppliers creating a complete U.S. solar cell production ecosystem and their solar cells are proven to self-anneal radiation damage on orbit. This acquisition positions York to meet the program timelines our customers require, without the supply chain vulnerabilities that put others at risk."
