Google Launches 'Space Data Center' Orbital Experiment Google Unveils Its Own AI Chip!
Google's 'Suncatcher' project has taken a crucial step. The first prototype satellite was successfully launched into orbit on October 1, 2026, and confirmed to be operating normally, beginning tests on the performance of TPU chips in the extreme environment of space. 🛰️ First Mission: MVP Prototype Satellite This satellite, codenamed MVP (Minimum Viable Product), is the size of a refrigerator and was manufactured by Planet Labs. It is equipped with 4 of Google's sixth-generation Trillium TPUs, providing a total computing power equivalent to a single data center server, and is powered by solar panels with an output of approximately 1 kilowatt (kW). The satellite was launched aboard SpaceX's Transporter-18 rideshare mission from Vandenberg Space Force Base in California. 🔬 Three Key Verification Items The goal of this mission is not to directly operate a data center, but to collect real-world data and verify the following core technologies: · Radiation Resistance: High-energy particles in space can cause 'Bitflip' errors. Google has confirmed through ground-based particle accelerators that the Trillium TPU can withstand the radiation dose for over 5 years of mission life, but its long-term effects need to be verified in orbit. · Vacuum Cooling: Space lacks air convection, so Google is using heat pipes combined with radiators (Radia

Author· Vacuum Cooling: Space lacks air convection, so Google uses a structure combining heat pipes and radiators for cooling. The TPU will operate in pulsed mode for about 15 minutes per cycle to prevent overheating. · Power and Computation: Under a power limit of approximately 1 kW, the satellite will run simple AI inference tasks like the Gemma model, observing its stability. 🗺️ Future Roadmap and Challenges The long-term goal of Suncatcher is to establish an orbital data center composed of a tight formation of 81 satellites, interconnected at high speed via laser optical communication. The plan is to launch two test satellites in 2027 to verify inter-satellite laser communication technology. However, the plan faces immense economic challenges. Google's research estimates that to reduce launch costs to $200 per kilogram, SpaceX's Starship may need to launch approximately 1,800 times over the next 10 years. Building a 1 GW-class orbital data center could cost up to $30 billion. Additionally, orbital congestion and space debris are potential risks. Google officially views this as a long-term 'moonshot project,' adopting a cautious approach and expecting concrete results in about 15 years, similar to autonomous driving technology.
