Despite significant hype surrounding space-based data centers, the number of GPUs currently operating in orbit remains extremely limited. As this situation begins to change, short-term commercial models for orbital computing power are gradually taking shape.
The largest operational computing cluster in orbit was launched in January by Canadian company Kepler Communications. It consists of approximately 40 NVIDIA Orin edge processors distributed across 10 satellites, interconnected via laser communication links.
The company has already secured 18 clients and announced a new partnership on Monday with startup Sophia Space. The latter will test its specialized orbital computer software on Kepler's satellite constellation.
Experts predict that large-scale space data centers, similar to those envisioned by SpaceX or Blue Origin, are unlikely to emerge before the 2030s. The immediate first step involves real-time processing of data collected in orbit to enhance the effectiveness of space-based sensors used by businesses and government agencies.
Kepler Communications CEO Mina Mitry stated that the company does not position itself as a data center firm but as an infrastructure provider for space applications. It aims to function as a service network layer, offering connectivity support to other satellites in space as well as to drones and aircraft on the ground.
Sophia Space, meanwhile, is developing passively cooled space computers. This innovation could address one of the core challenges of large orbital data centers: preventing high-performance processors from overheating without the need to build and launch heavy, expensive active cooling systems.
Under the new agreement, Sophia will upload its proprietary operating system to one of Kepler's satellites and attempt to deploy and configure it across six GPUs shared between two spacecraft. While such operations are standard in terrestrial data centers, this marks the first attempt in space. Ensuring stable software operation in orbit will be a critical risk mitigation step for Sophia before it plans to launch its first satellite by the end of 2027.
For Kepler, this collaboration helps demonstrate the practical value of its network. Currently, the company primarily transmits and processes two types of data: information uploaded from the ground and data collected by payloads onboard its own satellites. As the industry matures, Kepler plans to begin interfacing with third-party satellites to provide networking and computing services.
