In an Oct. 1, 2026, update, Google said its Project Suncatcher prototype had launched aboard SpaceX’s Transporter-18 rideshare mission, made contact and was operating as expected. Built with Planet, the spacecraft is a research test of AI hardware in orbit—not an operational orbital data center. The update adds an initial-contact report to NeoTeo’s earlier coverage of the planned launch.

What the orbital test is designed to learn

Project Suncatcher is a long-term research effort exploring whether space could support machine-learning infrastructure. The prototype is intended to gather data on how Google’s Tensor Processing Units (TPUs)—processors designed for AI workloads—handle launch stress, radiation and extreme temperatures.

Google says laboratory vibration tests simulated rocket-launch frequencies. In the launch scenario it describes, spacecraft loads can reach 10 g, while individual TPU components can experience 50–100 g. Those figures describe launch stresses, not the satellite’s computing performance in orbit.

Google also reports that Trillium TPUs survived a ground-based proton-beam radiation test at a dose greater than the dose projected for a five-year space mission. That was a laboratory test, not an in-orbit result.

Why cooling is part of the research

Computing hardware produces heat, so managing temperature is one of the project’s engineering challenges. Google says it has tested heat pipes and radiators in a thermal-vacuum chamber as it investigates how to remove heat from the spacecraft.

That work is part of figuring out how the hardware performs in space. The prototype’s reported launch and initial contact mark an early research milestone; they do not amount to a working data center in orbit.

Google plans a two-satellite laser test in 2027

Google’s project explainer describes a future design in which satellites could carry dozens of TPUs and communicate using lasers. The company says it plans to put two satellites in orbit in 2027 to test that inter-satellite connection. That is the next stated orbital milestone for the research project.
