"The largest compute cluster currently in orbit was launched by Canada's Kepler Communications in January, and boasts about 40 Nvidia Orin edge processors onboard 10 operational satellites, all linked together by laser communications links."
"Kepler doesn't see itself as a data center company, but as infrastructure for applications in space, CEO Mina Mitry tells TechCrunch. It wants to be a layer that provides network services for other satellites in space, or drones and aircraft in the sky below."
"Sophia, on the other hand, is developing passively-cooled space computers that could solve one of the key challenges for large-scale data centers in orbit: keeping powerful processors from overheating without having to build and launch heavy, expensive active-cooling systems."
"Making sure the software works in orbit will be a key de-risking exercise for Sophia ahead of its first planned satellite launch in late 2027."
Kepler Communications has launched the largest compute cluster in orbit, featuring 40 Nvidia Orin processors across 10 satellites. The company has 18 customers, including Sophia Space, which is testing software for its orbital computer. Experts predict large-scale data centers in space won't emerge until the 2030s. Kepler aims to provide infrastructure for applications in space rather than functioning as a data center. Sophia is developing passively-cooled space computers to address overheating challenges. Their partnership will test software across GPUs in orbit, marking a significant step for space-based computing.
