Google Aims for Space-Based AI Computing with Project Suncatcher

Google is pushing forward with its ambitious project to develop AI data centers in space. The company plans to launch an experimental satellite called MVP on October 1 aboard a SpaceX Falcon 9, carrying four specialized AI chips that can process about one kilowatt of solar power. These chips have computing power roughly equivalent to one data-center server.

The radiation testing for these chips has shown promising results, with Google finding that errors caused by radiation can be corrected by restarting the chips. However, cooling the chips remains a significant challenge in space, and Google developed a system using conductive materials and radiator panels to transfer heat into space.

Google acknowledges that building a large-scale orbital data center network could take years and require substantial investment, but estimates costs could become comparable with terrestrial data centers by the mid-2030s as launch costs decline. The company plans to launch two additional satellites in 2027 and is exploring fleets of more than 80 satellites that could work together to process AI queries.
