"At Lonestar, we are building the future of resilient, sovereign data storage in space,” Chris Stott, chair and founder of Lonestar, said in a statement. “Having already tested data storage from the lunar surface and in cislunar space, we are now scaling toward constellations of connected vaults across every orbit, and doing that at scale needs power."
He continued: "Space Solar's in-space assembly capability is key. [Its] platforms could one day host hundreds, even thousands, of our systems as a single connected fabric in space. Teaming up with Sam (Adlen), Martin (Soltau), and the Space Solar team is a significant step forward for both companies, and for the orbital data economy as a whole."
Lonestar has successfully demonstrated data operations on the lunar surface, including storing a DCD article in February 2025.
