Satlyt Moves Closer to Turning Satellites Into Space Data Centers

Satlyt says it completed a successful test this month after 13 months of work, moving closer to its goal of turning spacecraft — starting with satellites — into virtual data centers. The test was conducted with the University of Houston as part of a NASA-funded research project. It showed how Satlyt’s software can assign tasks among computers in orbit based on available compute and communications conditions. The key takeaway: this is a step toward shared computing in space, not a finished orbital data center network.

The company created a simulated network with four computers, four users, and eight services. One physical computer aboard a spacecraft ran the experiment, evaluated the simulated network of four computing hosts, and returned the results to Earth. According to Satlyt, the test proved its software can generate plans on hardware in orbit. The next milestone is testing how multiple physical computers transfer information among each other in practice.

Satlyt’s broader aim is to help operators run AI and other applications onboard spacecraft, processing data closer to where it is collected. That could reduce dependence on downlinks and ground-based analysis, which matter when satellites have limited communications windows. A cited example is wildfire detection: onboard processing could help transmit relevant information faster. For readers tracking space infrastructure, the trend to watch is software that makes satellites more useful as compute nodes, not just sensors or relays.

Satlyt says more validation is needed across workloads, hardware, and connectivity conditions. The company also found an issue in how its software time-referenced delays, recording arrival time rather than elapsed delay. The test still succeeded in software development, onboard execution, and returning outputs, but the company says it needs usable communication links, operator permissions, secure transfers, resource scheduling, and recovery when connections become unavailable. Satlyt is also researching applications beyond low Earth orbit, including support for 4K video streaming from the Moon through its NASA-funded work.
