Suncatcher: Google moonshot to move data centres to space, Pg15

Key Highlights:

• Google announced Project Suncatcher, aiming to establish solar-powered data centers in space by 2027.
• The project involves equipping satellite constellations with Tensor Processing Units and optical links for machine learning computations.
• Google plans to launch two prototype satellites in partnership with Planet Labs by early 2027.
• Other companies like OpenAI, Nvidia, and Lonestar Data Holdings are also exploring space-based data solutions.

Detailed Insights:

• Project Suncatcher seeks to address issues like excessive water depletion and fossil fuel usage associated with terrestrial data centers.
• Space-based data centers offer potential benefits such as climate predictability and circumventing data sovereignty restrictions on Earth.
• The UN Outer Space Treaty of 1967 may provide a loophole, allowing lunar data centers to host clients from multiple countries without national appropriation.
• Challenges include high establishment costs, difficulties in repairs, data transmission delays, and ensuring cybersecurity in space.
• OpenAI's Stargate project and initiatives like the Star-cloud satellite with Nvidia's H100 GPU indicate growing interest in space-based AI infrastructure.
• Lonestar Data Holdings has already sent a mini data center to the moon, and Amazon plans to follow, signaling a trend toward extraterrestrial data storage.

Key Concepts Involved:

• Data Sovereignty: The concept that data is subject to the laws and governance structures of the country in which it is collected or stored.
• Tensor Processing Unit (TPU): Google's custom-developed application-specific integrated circuit (ASIC) used to accelerate machine learning workloads.
• Outer Space Treaty: An international treaty prohibiting military activities, weapons, and national appropriation of outer space and celestial bodies.
